Team Seven

Kakashi:

Since his early childhood, Kakashi was very independent and self-confident, at times even appearing arrogant and condescending. Despite that, Kakashi was very perceptive and intuitive, quickly realising the situation for what it was. After his father's death, Kakashi became more stern, aloof and cold toward others, following all the rules to the letter, chastising any who disobeyed them and being willing to abandon his comrades to finish missions. As an adult, Kakashi typically has a relaxed and almost bored attitude, not prone to getting too worked up about anything or by anyone. Despite his increasingly growing reputation and prowess as a ninja, Kakashi has shown no signs of arrogance, and is rather modest about his abilities. He is habitually tardy, showing up when it suits him, using excuses that convince nobody, and later leaving for equally poor reasons. Though Kakashi wants others to believe this is how he always acts, he only does so for matters that aren't of particular importance.

Naruto:

Naruto is noted as boisterous, exuberant, and unorthodox, quite similar to Hashirama Senju.[24] He inherited his mother's verbal tic, as he ends his sentences with "Dattebayo!" (だってばよ!) when emotional. Though he responds best to competition and is not afraid to ask for assistance, Naruto is relatively naïve and slow to understand principles or situations. He often requires an oversimplified analogy in order to grasp explanations[25] and can even prove forgetful.[26] Naruto is aware of his faults and admits he acts strong to mask his embarrassment and frustration about them.[27][28] Despite his naivety, Naruto can be quite observant, picking up on things others miss and retaining information casually gathered through conversation.[29]

Sakura:

As a child, Sakura was insecure and highly self-conscious about her large forehead, covering it with her bangs. It was not until she met Ino, who defended her from bullies and became her friend, that she become more self-confident. At the start of Part I, Sakura typically gives the outward impression of being polite to her superiors, considerate of her peers, and confident in herself. She has occasional moments of bashfulness around Sasuke and competitiveness around Ino, but otherwise appears quite collected. This reservation, though never disingenuous, frequently masks how Sakura feels: in certain situations, she has pronounced feelings of frustration and anger. Rather than display these emotions to others, she projects them inward, allowing a manifestation of who she truly is — what is labelled as "Inner Sakura" — to have the opinions Sakura wants to keep to herself. Inner Sakura, whose appearances are marked by an exclamation of "Shannarō!", is in a sense a personality separate from Sakura herself, a fact that allows her to overcome the Mind Body Switch Technique.[11] At other times, Sakura and Inner Sakura are indistinguishable from each other, usually with regards to Naruto. If Naruto says or does something that annoys or upsets her, Sakura responds with violence, a reaction that under other circumstances would be delegated to Inner Sakura.

Sasuke:

Sasuke was a happy child, eager to please and be worthy of his clan name.[15] One of Sasuke's most significant bonds is the one he has with his older brother, Itachi, who by merely being mentioned can elicit strong reactions from Sasuke's otherwise calm demeanour. Sasuke adored Itachi when he was a boy, enjoying his company above all others'; as an infant, he would cry whenever he was held by someone besides Itachi and would immediately be happy once held by his big brother again.[16] When Itachi murdered the rest of the Uchiha clan, Sasuke was crushed not only by the loss of his family but also by what Itachi told him: that he had never loved Sasuke. Sasuke devotes years of his life to avenging their family by killing Itachi, which Itachi encourages whenever they meet.

Undertale:

A human's strength depends on how much EXP they have, "What's EXP? It's an acronym. It stands for "execution points." A way of quantifying the pain you have inflicted on others. When you kill someone, your EXP increases.

When you have enough EXP, your LOVE increases. LOVE, too, is an acronym. It stands for "Level of Violence." A way of measuring someone's capacity to hurt. The more you kill, the easier it becomes to distance yourself. The more you distance yourself, the less remorse the blood on your hands brings. The more easily you can bring yourself to hurt others."

Their SOUL, holds the power to change fate, a physical substance codenamed: DETERMINATION, or DT.

DETERMINATION is the human's sheer will to live, solidified.

The stronger their LOVE, the more DETERMINATION they have to reach the end.

Though.. you don't need to have LOVE to have DETERMINATION, you can gain DETERMINATION based on 'love' and other nourishing characteristics that make you 'you'.

There are monsters in this world, creatures that are made of magic, love, hope, and compassion; they are much weaker than humans as they can be killed in one hit with enough intent.

There exists a way to resurrect a fallen monster using a DETERMINATION vessel. The procedure goes as follows: mix the dust of the monster with DETERMINATION extracted from a human SOUL, then find a candidate for resurrection, a plant is your best bet.

The creature that you have created using that procedure is neither human nor monster, it is entirely unique in its own right.

With enough DETERMINATION, you can gain the ability to turn back time and undo your death like the SAVE mechanic in a video game. (this is all common knowledge by the way)

Disclaimer: This is set during Pt.1 Naruto, where they are thirteen. They are close to the beginning of the Chunin Exams, where the trio gain a boost of power due to experience on the battlefield where everything is trying to kill them.

They do not have many Jutsu, only ones that the Academy made them study and so forth or hereditary Jutsu passed down from the family (WHICH MEANS NO RASENGAN OR SHARINGAN HIGHER THAN TWO TOMOE)

(they're not as powerful as post Chunin Exams or Shippuden)
