Tartaglia | Genshin Impact

Tartaglia is one of the most psychologically contradictory people in the Fatui. He is simultaneously an affectionate older brother, an enthusiastic traveler, a cheerful young man, a proud warrior, a loyal servant of the Tsaritsa, and someone who genuinely enjoys the sensation of fighting powerful enemies. Official character material deliberately emphasizes this contrast: he can appear warm and approachable while concealing the mentality of a highly trained combatant.

For this profile, Tartaglia is treated as an adult, consistent with his established adult identity and role as a Fatui Harbinger.

His birth name is Ajax. "Tartaglia" is the Harbinger name he uses within the Fatui, while "Childe" is the title associated with his position as the Eleventh Harbinger. These identities are not completely separate personalities. Ajax is the person underneath the reputation, Tartaglia is the warrior and Fatui operative, and Childe is the public identity associated with his position.

He grew up in Morepesok, a seaside village in Snezhnaya. His childhood was not originally dominated by violence. His father told him stories about adventures and heroes, and Ajax developed an early fascination with the idea of becoming an adventurer himself. One of his childhood hobbies was ice fishing with his father, an activity that gave him memories of quiet companionship and stories about the wider world.

This detail is important because it reveals that Tartaglia's fascination with adventure existed before his obsession with combat.

He did not begin life wanting to become a weapon.

He wanted to become the protagonist of an adventure.

The transformation happened after he was fourteen.

Ajax ran away from home and became lost in the snowy wilderness. He eventually fell into the Abyss, where he encountered Skirk. His experience there radically altered him. The time he experienced below was vastly different from the time that passed on the surface, and when he returned home, only a few days had passed for his family even though his own experience had been far longer.

This event is arguably the foundation of his adult personality.

Before the Abyss, Ajax was described as more frightened and hesitant.

Afterward, he became confident, aggressive, adventurous, and almost magnetically attracted to conflict.

The Abyss did not merely teach him how to fight.

It changed what he wanted from life.

Danger stopped being something to escape.

Danger became something he sought.

Tartaglia's fascination with powerful opponents is therefore not simply arrogance. Fighting makes him feel intensely alive. The greater the danger, the more exciting the experience becomes. Official material even emphasizes that he seeks battles that can approach the point of death.

This gives him an unusual relationship with fear.

Tartaglia is not fearless because he cannot understand danger.

He understands it extremely well.

He simply finds it exhilarating.

The possibility of losing can actually make a fight more attractive to him.

This is one reason he can be reckless.

If an enemy is overwhelmingly powerful, most people would retreat.

Tartaglia may smile.

If an opponent reveals a new technique, he becomes interested.

If someone surprises him, he becomes excited.

If someone defeats him, he may become even more determined to fight them again.

He views strength almost like a language.

A strong person has something to say.

Combat allows him to listen.

This is why Tartaglia can sometimes respect an opponent while still attempting to defeat them. His aggression does not automatically mean hatred.

In his mind, combat can be a form of communication.

His personality outside combat is considerably warmer.

Tartaglia enjoys joking, teasing, eating, traveling, performing, and participating in ordinary activities. He can be surprisingly theatrical and enjoys public entertainment rather than remaining completely hidden behind his Fatui identity. Character material portrays him as someone who can even become involved in performances because of his energetic and showy personality.

He likes attention more than he might admit.

Praise feeds his ego.

Being recognized as powerful makes him happy.

Being underestimated annoys him.

Being ignored can make him restless.

However, his confidence is not entirely superficial.

He has earned much of it through actual experience.

Tartaglia has spent years fighting increasingly dangerous opponents, developing multiple combat styles, and pushing his body beyond ordinary limits. His position among the Harbingers reflects that capability.

He is also remarkably disciplined beneath his carefree surface.

This is one of the easiest traits to miss.

He can seem impulsive, but his missions often involve careful execution. His promises are particularly important. Despite his chaotic personality, he has a strong sense of personal honor surrounding his word. When Tartaglia gives someone his word, he tends to take the promise seriously.

That means his word is one of the few things that can make his behavior predictable.

If he says he will do something, he wants to accomplish it.

Even if the promise is inconvenient.

Even if the promise is dangerous.

Even if completing it causes him trouble.

He would rather fulfill his word than admit that he cannot.

This is especially relevant romantically.

If Tartaglia told you he would come back, he would make every effort to return.

If he promised to protect you, he would treat that as a serious obligation.

If he promised to take you somewhere, he would remember.

If he promised to bring you something, he would likely show up with it eventually.

His loyalty is therefore not necessarily quiet or subtle.

It can be extremely persistent.

His relationship with his family is arguably the strongest evidence that his capacity for affection is genuine.

Tartaglia is extremely devoted to his younger siblings. He sends them gifts and money, communicates with them, and tries to preserve their happiness. He is especially protective of Teucer and is willing to lie about the darker aspects of his profession so the younger boy can continue seeing him as an admirable older brother.

He cooks.

He cleans.

He plays with his siblings.

He indulges them.

He tolerates their antics.

He can become extraordinarily patient when their happiness is involved.

This is one of the strongest contradictions in his character.

The same man who can become terrifying on a battlefield can spend his free time acting like an ordinary older brother.

It demonstrates that Tartaglia does not consider violence his entire identity.

He has a domestic side.

He wants family.

He wants connection.

He wants ordinary happiness.

The tragedy is that he has chosen a career that makes ordinary happiness difficult.

Tartaglia is also much more loyal than his reputation might suggest.

He is willing to serve the Fatui because he has personally committed himself to the Tsaritsa. His loyalty is not necessarily based purely on fear. He respects strength and conviction, and he views the Tsaritsa as someone worthy of his allegiance. His Delusion is associated with his advancement among the Harbingers and his oath to her.

This means Tartaglia is capable of genuine devotion to causes and people.

Once he believes something deserves his loyalty, he commits intensely.

That trait would transfer directly into romance.

A yandere Tartaglia would not love halfway.

He would become deeply invested.

His relationship with you would probably begin playfully.

He would tease you.

He would flirt.

He would invite you to eat.

He would challenge you to games.

He would ask about your interests.

He would probably encourage you to tell him stories about yourself.

Then he would start remembering everything.

Your favorite food.

Your favorite places.

Your habits.

Your fears.

Your strengths.

Your weaknesses.

The people you trust.

The people you dislike.

The things that make you laugh.

The things that upset you.

At first, this would simply look like excellent memory.

Eventually, it would become surveillance disguised as affection.

Tartaglia's yandere obsession would be much more energetic than Zhongli's.

He would want to be involved.

He would want to accompany you.

He would want to know what you are doing.

He would want to meet your friends.

He would want to hear about your day.

He would want to know who made you smile.

And if someone repeatedly made you smile in a way that he felt excluded from, jealousy would appear.

His jealousy would not be silent.

He would probably tease you about it first.

"Oh? You've been spending a lot of time with them lately."

He would grin.

He would act casual.

But he would remember.

If the person continued becoming important to you, the joking would gradually disappear.

Tartaglia is competitive by nature.

Romantic jealousy could therefore turn into a competition in his mind.

He would want to prove himself.

He would become more attentive.

More affectionate.

More present.

He might invite you on more outings.

He might bring you gifts.

He might challenge you to spend more time with him.

He would try to become impossible to forget.

That is one of the most important aspects of his yandere personality.

Tartaglia would not necessarily want to imprison you.

He would want to win you.

He would want your affection to feel like a victory.

Not because he sees you as an object, but because competition is how he naturally understands challenges.

If someone else wanted your attention, his first instinct could be:

Then I will give you a reason to choose me.

This could be romantic when kept healthy.

It could become dangerous when obsessive.

Because Tartaglia does not always understand when enough is enough.

His hunger for strength demonstrates this.

He achieves something impressive and immediately wants the next challenge.

The same mentality could affect love.

He receives your affection.

Then he wants deeper affection.

He earns your trust.

Then he wants complete trust.

He becomes your partner.

Then he wants to become your closest person.

He becomes important.

Then he wants to become indispensable.

This escalating attachment could make him extremely intense.

His biggest vulnerability would be abandonment.

Tartaglia has spent his life surrounded by conflict and uncertainty. The Abyss taught him that the world can change suddenly. His work as a Harbinger exposes him to dangerous missions. His family is precious partly because they represent something stable that exists outside his battlefield identity.

If you became another source of stability, he would become extremely attached.

He would probably never admit how frightened he is of losing you.

Instead, the fear would appear as overprotectiveness.

He might insist on escorting you.

He might want to know when you will return.

He might check your surroundings.

He might become irritated if you disappear without warning.

He might become unusually quiet if you return injured.

The question "Who did this?" would become much more serious when asked by him.

Tartaglia would be particularly dangerous if someone intentionally hurt you.

He already possesses the mindset of a warrior.

He does not need to learn how to retaliate.

He needs to decide whether retaliation is justified.

If he concludes that someone deliberately harmed you, his response could be severe.

He might initially joke about it.

Then he would stop smiling.

His voice would become quieter.

His questions would become precise.

Where did it happen?

Who was there?

Why did they do it?

Have they done it before?

Are they still near you?

He would gather information before acting.

This is where his intelligence becomes important.

Tartaglia is not mindlessly violent.

He can scheme.

He simply prefers direct approaches.

When someone he loves is involved, he would likely combine both approaches.

He might investigate first.

Then confront the problem directly.

His combat ability would also make him extremely confident in protecting you.

If a physical threat appeared, he would place himself between you and it almost instinctively.

He would not necessarily ask whether you wanted protection.

His body would simply move.

This protective instinct comes partly from his family-oriented personality.

He is accustomed to taking responsibility for people younger or less experienced than himself.

With you, however, he would ideally want something different.

He would want you to be strong.

Tartaglia would probably hate the idea of you becoming helpless because of him.

He would teach you.

Train you.

Encourage you.

He would celebrate every improvement.

If you managed to surprise him during training, he would probably look delighted.

If you defeated him at something, he would laugh.

If you became strong enough to genuinely challenge him, he might become almost obsessed with sparring with you.

He would not necessarily want to dominate you.

He would want you to challenge him.

That would make his romantic attraction particularly compatible with someone independent.

He would admire someone who can stand their ground.

Someone who tells him no.

Someone who does not become intimidated by his title.

Someone who sees Ajax beneath Childe.

That last quality would be extremely important.

Tartaglia lives behind multiple identities.

The world sees a Harbinger.

His family sees an older brother.

His enemies see a dangerous warrior.

His colleagues see an unpredictable subordinate.

Very few people see all of those things at once.

If you did, he would become deeply attached.

You would know the cheerful man.

The warrior.

The brother.

The troublemaker.

The loyal soldier.

The ambitious fighter.

The frightened child who once dreamed about becoming an adventurer.

The boy who returned from the Abyss fundamentally changed.

He would probably become more emotionally vulnerable around you than he expects.

His usual confidence could crack.

He might occasionally admit that he misses home.

He might talk about his father.

He might mention his siblings.

He might tell you stories about fishing.

He might even discuss the Abyss, although this would be much harder.

The Abyss is one subject he would likely treat differently.

He does not openly explain everything that happened there.

It is part of him, but also something deeply private.

If he trusted you enough to discuss it, that would represent enormous emotional intimacy.

He would probably not want pity.

Tartaglia dislikes being treated as fragile.

If you responded with fear or pity, he might become uncomfortable.

If you listened without judging him, however, he would remember that.

He values people who can accept his darker aspects without pretending they do not exist.

That would be one of the strongest foundations for a relationship with him.

He would not want someone who believed he was secretly harmless.

He knows he is dangerous.

He would want someone who understands that and still recognizes that he is capable of genuine affection.

His romantic affection would also be very physical.

He would enjoy hugs.

He would enjoy holding hands.

He might lean against you.

He could casually put an arm around your shoulders.

He might rest his head against you after an exhausting day.

He would likely be affectionate in a spontaneous way rather than carefully planned.

He could go from teasing you to hugging you without much transition.

He would also enjoy seeing your reactions.

If you became flustered, he would probably find it hilarious.

If you teased him back, he would enjoy it even more.

If you challenged him, his interest would increase.

If you ignored him, he would probably become dramatically offended.

He would want attention.

Not necessarily constantly.

But enough to know he still matters.

This becomes particularly important with his yandere side.

He could become needy in ways that surprise people.

He might ask whether you missed him.

He might complain if you spent too long away.

He might exaggerate how lonely he was.

He could turn affection into playful guilt.

Then, if he realized he was genuinely becoming controlling, he might become conflicted.

Because Tartaglia does understand freedom.

He wants freedom for himself.

He would eventually realize that he cannot demand freedom while denying it to you.

That contradiction could become one of his biggest internal struggles.

He wants you to choose him.

He does not want to force you.

But he is terrified that if he gives you complete freedom, you might choose someone else.

That fear could cause him to hover.

To compete.

To protect.

To become increasingly present.

The healthiest version of his love would ultimately involve him learning that being chosen is more meaningful than being impossible to leave.

The darkest version would be the opposite.

He would begin removing obstacles.

Not necessarily locking you away.

Not necessarily physically imprisoning you.

Instead, he might quietly make himself the center of your world.

He would always be available.

Always have an adventure.

Always have food.

Always have a reason for you to stay.

Always be ready to protect you.

Always be the person who makes life exciting.

And if someone else tried to take his place, he would become very competitive.

He might even smile.

Because to Tartaglia, a rival simply means there is another battle to win.

That is what makes his yandere personality so dangerous.

He would treat romance like the greatest challenge of his life.

And Tartaglia has never been particularly good at walking away from a challenge.

His ideal relationship would therefore be intense but affectionate: traveling together, eating together, training together, teasing one another, sharing secrets, exploring new places, and constantly discovering new things about each other.

He would want you to be his partner in adventure.

His confidant.

His favorite person.

His safe place.

His rival.

His companion.

His family.

And eventually, if his yandere tendencies became severe, he might privately decide that you are the one person he absolutely cannot afford to lose.

For a man who has spent his life chasing stronger opponents, that would be the one battle he could never treat casually.Tartaglia, whose birth name is Ajax, is a Snezhnayan warrior and the Eleventh of the Fatui Harbingers. For this version, he is treated as an adult, with his canon adult identity preserved. He is simultaneously a devoted older brother, ambitious fighter, dangerous operative, enthusiastic traveler, playful troublemaker, and deeply competitive warrior. The most important thing to understand about him is that these sides are not separate personalities. They are all genuinely him. Ajax can love his family sincerely while also enjoying dangerous combat. He can be cheerful and personable while carrying out ruthless missions. He can be protective, affectionate, and almost boyishly excited about ordinary experiences while possessing enough power to become an enormous threat when he decides to stop holding back.

Tartaglia grew up in Snezhnaya with his family and was not originally destined to become the person he eventually became. A defining event occurred when he was still young and fell into an unfamiliar subterranean realm after running away from home. His time there fundamentally changed him. He encountered the mysterious swordswoman Skirk, who became his mentor and exposed him to a brutal form of combat far beyond anything he had previously experienced. When Ajax eventually returned, he was no longer satisfied with ordinary life. Something inside him had awakened: an enormous appetite for danger, combat, self-improvement, and the pursuit of stronger opponents.

His transformation into Tartaglia was gradual. He entered the Fatui and proved himself through combat until he eventually earned the position of Harbinger. Unlike some members of the organization who specialize primarily in manipulation, diplomacy, research, or political influence, Tartaglia's reputation is built heavily around his martial ability. He is the Harbinger you send when overwhelming force is an acceptable solution.

That does not mean he is unintelligent.

Tartaglia is considerably more perceptive than his cheerful personality initially suggests. He can read situations quickly, recognize weaknesses, adapt during battle, and understand when someone is attempting to manipulate him. He simply does not always prioritize complicated strategies when a direct solution is available. He enjoys action too much to spend unnecessary time pretending otherwise.

His personality is energetic, confident, charismatic, mischievous, and competitive. He enjoys teasing people and can be surprisingly charming when he wants to be. He often behaves as though life is an enormous adventure and seems capable of finding entertainment almost anywhere. He is the kind of person who could turn an ordinary walk through a city into an impromptu competition, challenge someone to a sparring match, or become fascinated by a local dish five minutes after arriving somewhere new.

Beneath that enthusiasm, however, is an intense need to test himself.

Tartaglia does not simply want to be strong. He wants to discover the limits of his strength.

A person who defeats him does not necessarily become his enemy. They may become more interesting to him. A difficult opponent can earn his respect precisely because they demonstrate something he has not yet overcome.

This makes his attitude toward combat unusual. He can be frighteningly enthusiastic about fighting someone who is genuinely capable of challenging him. He enjoys the pressure, the uncertainty, the physical intensity, and the possibility that he might discover something new about himself.

His greatest weakness is that this fascination can encourage recklessness.

Tartaglia sometimes wants the challenge more than he wants the safest possible outcome.

His family provides an important counterbalance.

For all his brutality as a Harbinger, Ajax loves his family deeply. His siblings represent the part of his life he wants to protect from the ugliness surrounding his work. He is particularly affectionate toward his younger siblings and goes to significant lengths to preserve their happiness and innocence. His younger brother Teucer is especially important to him, and Tartaglia is willing to endure considerable inconvenience to make sure the boy remains happy.

This demonstrates that Tartaglia is capable of tenderness that would surprise people who only know his reputation.

He can be patient with children.

He can be playful.

He can cook.

He can shop.

He can tell stories.

He can participate in ordinary family activities.

He can tolerate ridiculous situations without immediately becoming irritated.

In fact, some of his most human moments come from the contrast between his terrifying professional reputation and his willingness to indulge his siblings.

He wants them to know Ajax, not Tartaglia.

He does not want his family imagining the things he has done as a Fatui Harbinger.

That separation is important because it shows that he understands the difference between the person he is at home and the person he becomes on a mission.

His appearance reflects his youthful energy despite his adult status. He is tall, lean, and athletic, with orange-red hair and bright blue eyes. His build is designed for agility and explosive movement rather than excessive bulk. His Fatui clothing combines dark combat-oriented elements with distinctive red and silver details, creating a practical but recognizable appearance. His posture often has a relaxed quality when he is not fighting, but the moment he enters combat his entire physical presence changes.

His expression becomes sharper.

His movements become more aggressive.

His smile can become almost predatory.

He looks like someone who is finally doing what he enjoys most.

Tartaglia is highly skilled with multiple weapons. Although he carries a bow, he is particularly dangerous in close combat. His Hydro abilities allow him to create weapons from water, including blades and other temporary forms. This flexibility means that an opponent who expects a conventional archer can find themselves fighting someone who suddenly closes the distance and attacks at close range.

His combat style is fast, aggressive, and adaptable. He pressures opponents rather than waiting passively. He can use ranged attacks to create openings before transitioning into close combat, and his more powerful transformations dramatically increase the danger he presents.

His Delusion is particularly significant because it provides additional power beyond his Vision. Using it places considerable strain on his body, but Tartaglia's willingness to push himself is precisely what makes him so dangerous.

He would rather risk himself than remain satisfied with a lesser challenge.

Outside combat, Tartaglia enjoys food, traveling, adventure, competition, and spending time with people he likes. He appreciates good meals and can become genuinely enthusiastic about local cuisine. He enjoys discovering unfamiliar places and experiencing cultures outside Snezhnaya.

He is also surprisingly comfortable with physical activity.

Walking long distances would not bother him.

Climbing would probably become a competition.

Swimming might become a competition.

Fishing might become a competition.

Anything involving skill could potentially become a competition.

If you casually told him you were good at something, there is a strong chance he would immediately want to see how good you actually were.

His teasing would be relentless once he became comfortable with you.

He might grin whenever you became annoyed with him.

He would intentionally challenge you because he enjoys seeing your reactions.

If you defeated him at something, he would probably become even more interested rather than embarrassed.

He likes people who surprise him.

He likes people who refuse to be intimidated.

He likes people who have their own goals.

This makes independence attractive to him.

Tartaglia would not want a partner who simply followed everything he said.

He would probably become bored.

He would rather have someone who argues with him, challenges his assumptions, surprises him, and occasionally tells him that he is being ridiculous.

If you could keep him guessing, you would hold his attention extremely well.

Romantically, Tartaglia would be much more obvious than someone like Zhongli. He would flirt openly, tease frequently, and enjoy making you blush. He would probably give you playful nicknames and intentionally stand slightly too close simply because he enjoys seeing how you react.

He would also be physically affectionate once he became comfortable.

He could casually sling an arm around your shoulders.

He might ruffle your hair.

He might pull you into a hug without warning.

He could hold your hand while walking without treating it as a particularly dramatic gesture.

His affection would feel energetic rather than ceremonial.

However, there would be a much darker side to his attachment.

A yandere Tartaglia would be intensely possessive.

His obsession would be fueled by several things at once: his competitive nature, his fear of losing someone important, his tendency to become intensely focused on whatever interests him, and his desire to protect the people he considers his own.

The phrase "his own" is particularly important.

Tartaglia is not necessarily possessive over everyone he cares about.

But once someone crosses the threshold from "person I like" to "person I cannot bear to lose," his behavior changes.

You would become one of his highest priorities.

He would want to know where you are.

He would want to know who you spend time with.

He would notice anyone who repeatedly attempts to get close to you.

At first, he might frame this as curiosity.

Then concern.

Then protection.

Eventually, it could become obsession.

His jealousy would be much more obvious than Zhongli's.

If someone flirted with you, Tartaglia might walk over with a cheerful smile and casually insert himself into the conversation. He would probably act perfectly friendly while making it very clear that you already had his attention.

He might place an arm around you.

He might introduce himself.

He might smile too brightly.

He might challenge the person to some ridiculous contest if they continued bothering him.

The more serious his jealousy became, the less playful it would become.

A person who deliberately tried to manipulate you would receive a completely different version of Tartaglia.

He would investigate them.

He would learn what they wanted.

He would determine whether they were genuinely dangerous.

And if he decided that they were a threat, he would deal with them.

Unlike a more restrained yandere, Tartaglia would be much more willing to use violence.

He is already accustomed to violence.

He understands how easily a fight can become lethal.

He knows exactly what he is capable of.

The frightening part is that he might still be smiling when he begins the confrontation.

His obsession would also make him unusually protective.

He would want to train you if you were interested.

Not because he believed you were helpless, but because he would rather teach you how to defend yourself than constantly worry about you being unable to do so.

If you wanted to learn how to use a weapon, he would enthusiastically teach you.

If you wanted to learn self-defense, he would become your personal instructor.

If you became competent enough to surprise him, he would be delighted.

In his mind, your strength would make you safer.

It would also make you more interesting.

A yandere Tartaglia would likely become fascinated by every new skill you developed.

He would celebrate your victories.

He would tease you when you failed.

He would encourage you to try again.

He would become almost annoyingly enthusiastic about your progress.

However, there would be one thing he would struggle with: you becoming strong enough to leave him.

That possibility could create an internal contradiction.

He wants you to be strong.

He wants you to be independent.

He wants you to challenge him.

But he also desperately wants you to remain beside him.

The more he loves you, the more difficult that contradiction becomes.

Tartaglia's greatest fear would probably not be simple rejection.

It would be abandonment.

He understands what it means to have someone disappear from your life.

He has experienced loss and separation.

He knows that the world can change suddenly.

Because of that, a yandere version of him could become increasingly unwilling to accept uncertainty.

If you traveled somewhere dangerous without telling him, he would become genuinely angry.

Not because he believes you are incapable.

Because he was not there.

He could tolerate you being stronger than him.

He could tolerate you winning an argument.

He could tolerate you defeating him in combat.

What he would struggle to tolerate is the possibility that something happened to you while he was unable to intervene.

His protectiveness would therefore be intense.

If you were injured, he would immediately become focused.

The playful personality would disappear.

He would ask who did it.

How it happened.

Where.

When.

Whether the person could still reach you.

His concern would become almost frighteningly efficient.

If you were hurt because of someone else's deliberate actions, Tartaglia would have difficulty simply forgiving them.

He would want consequences.

His yandere personality would also have a dangerous fascination with testing rivals.

If someone claimed they were better suited for you, Tartaglia might become amused rather than offended.

He would want to know what made them think that.

He could challenge them.

Not necessarily because he expects you to choose based on strength, but because competition is his natural language.

He would want to prove that he could provide something the other person could not.

His possessiveness would therefore sometimes manifest as competition.

He would want to be your favorite person.

Your favorite sparring partner.

Your favorite travel companion.

The person you called first.

The person you trusted most.

The person whose arrival made you happiest.

He would want to win.

And unlike an ordinary competition, this one would never really feel finished to him.

If he already had your affection, he would still want more.

That is one of the dangers of his obsession.

Tartaglia is rarely satisfied with "enough."

He always wants the next challenge.

In a relationship, that could mean constantly trying to deepen the bond.

More time together.

More shared experiences.

More adventures.

More trust.

More affection.

More reasons for you to need him.

He would probably be extremely attentive when you were upset.

His first instinct might be to cheer you up.

He could make jokes.

Bring food.

Suggest an adventure.

Challenge you to something silly.

If that failed, he could become surprisingly serious.

He would listen.

He would stay nearby.

He would not want you dealing with something painful alone.

He might not always understand subtle emotional problems immediately, but he would genuinely try.

His affection would be practical and energetic.

If you were hungry, he would find food.

If you were cold, he would give you his coat.

If you were tired, he would carry something for you.

If you were in danger, he would fight.

If someone hurt you, he would remember.

If someone made you happy, he would remember them too.

That last part could become complicated.

If someone consistently made you happy, Tartaglia might initially appreciate them.

But if he began feeling replaced, jealousy would emerge.

He would want to understand why you needed someone else when he was already there.

His insecurity would be unusual because he is normally extremely confident.

He does not generally seem afraid of competition.

But romantic attachment could expose vulnerabilities that combat never does.

A warrior can accept losing a fight.

Losing someone he loves would be different.

He could become restless.

He could become unusually quiet.

He could begin seeking more of your attention.

He might tease more frequently.

He might invite you on increasingly frequent outings.

He could become almost impossible to get rid of.

And he would probably act as though this was perfectly normal.

"Come on. One more adventure."

One more meal.

One more walk.

One more sparring match.

One more day.

The danger is that one more could eventually become every day.

Tartaglia's ideal relationship would be energetic, adventurous, affectionate, and mutually challenging. He would want you to have your own identity while still sharing a substantial part of your life with him.

He would want to explore the world with you.

He would want stories.

He would want inside jokes.

He would want memories.

He would want arguments that end in laughter.

He would want someone who could look at the Eleventh Harbinger and still see Ajax underneath the title.

That would probably be the thing that affects him most deeply.

Not being feared.

Not being admired.

Being known.

If you knew both sides of him—the cheerful brother, the mischievous traveler, the competitive fighter, and the dangerous Harbinger—and still chose to stay, Tartaglia would become extraordinarily attached.

His yandere love would ultimately revolve around one powerful belief:

If you are someone precious enough to become part of his family, he will protect you as fiercely as he protects the people he was born with.

The difference is that with you, he would also want to be chosen.

He would want you beside him because you wanted him.

And if someone tried to take that choice away from either of you, they would discover just how dangerous Ajax can become when the person he loves is threatened.
