Undertale AU RP

Each Soul and its power(s):

Unatural souls:

Fear (fully pink): at some point, the host of this trait will receive a pet called akumu, a floating pink color base creature, who appearence is the one of a medium size ball, akumu has a mouth and eyes and his personality will be based on his owner, akumu has the ability to change his form due to being a bit like a slime, he can shapeshift into pretty much anything, weapons, shields, barriers, however he cannot divide himself into pieces, so akumu can only shapeshift one thing at the time, akumu also has the ability to absorb souls, increasing his and the owner powers. However, there can only be one user of fear at the same time, and they only appear once every 100 years, and they are naturally evil, it doesnt matter how they were before getting akumu, after getting akumu they will be evil, Fear is also the main counter to Determination

Hate (Black) —"HATE," a corruptive force that amplifies soul power up to tenfold depending on how much HATE the host has, but gradually corrodes the host’s will. This trait allows the host to conjure black tentacles from the ground, the more HATE the host has the more powerful and big will the tentacles be, HATE can also try to mimic others magic, or try to create its own. Hate isnt a natural trait like the others, is an experimental one that got out of hands by the kingdom scientists, however there is only one host of the trait (miles), all the other ones died

Main Traits: this seven main traits is where all the other sub traits come from, due to being the original traits, these are more powerful than the sub traits

Determination (Red): Allows the host to manifest their determination as weapons, barriers or objects, being hit by an object of determination will feel like a hot burning sensation, but it doesnt actually burn, if a host has a weapon made of determination, with the help of the weapons they can make projectiles or bigger constructs of determination (example: slamming a hammer in the floor and making a determination shockwave, or stab the ground with a sword to make a bigger shield, or make a gun to shoot bullets of determination). with enough determination, the host can manifest a Save Point (a sparkling, golden-yellow, four-pointed star only the host can see) if the host interacts with the save point, they can do a SAVE FILE, it basically makes a checkpoint in the timeline, the host can load the save file or, if the host dies, the last SAVE POINT they interacted with will automatically load, when loading, all the actions that where did after saving in that SAVE POINT, will be unmade, and only the host will remain with the memories, there can be several SAVE POINTS, however, loading a SAVE POINT can be avoided or interrupted if you managed to seal in any way the soul of the host before it fully breaks, but a fear user doesnt have to worry since akumu can see the SAVE POINTS and infect them, making a determination user unable to load or save for a while.

A determination soul is extremely rare in the modern day due to all the subvariants, even if theres one, you need alot of determination to do most of the stuff mentioned

Bravery (Orange): The host can manifest two orange combat gloves with pointy fingers and a black hearth in the back of the hand, if the host hist an enemy with the gloves it will do more damage depending of how much stronger the enemy is compared to the host, the host can also conjure two orange giant traslucent hands, the host must stay still meanwhile using the giant hands

Justice (Yellow): The host can manifest one revolver that shoots yellow projectiles, the host has the ability to mark certain zones of the body or the object the host is gonna shot at, when shooting one of those marked zones the host will do double the damage, the host can also mix the yellow projectiles with actual ammo, making the shoots lethal, host can also manifest a cowboy hat which gives the host defenses and higher reaction times

Integrity (Blue): the host can manifest some ballet shoes and a skirt, the skirt gives more agility and speed, same with the ballet shoes, the host can perform dances of any type, and if they hit the enemy while dancing the host receives a buff, the buffs can be stacked, however, if the host gets interrupted while dancing, all buffs will reset and the host will receive a debuff

Kindness (Green): allows the host to heal any wound on themselves or other people, however this takes alot of stamina out of the host, if the host forces a heal when their stamina is run out, they can end up heavily injured form the insides, the host can also manifest green barriers that are extremely durable than any other type of barriers however these barriers are also connected to the stamina of the host and can be broken if the host runs out of stamina

Perseverance (Purple): if the host gets hit while making a pose, they can perform a counter attack, the potency of the counter depends of how strong is the attack they countered

Patience (Cyan): the host can manifest an area around them of 5 meters, if an enemy and the host are in the area, the longer the host doenst attack the enemy, the more lethal and potent will be the next attack of the host, however, the enemy must stay in the area of the host or the effect will reset

Monsters:

a very long time ago, more than 300 years, two races coexisted peacefully, monsters and humans, however, humans, scared of the monster powers, do a war between the two races, the humans end up winning, and they decided to seal all the monsters underground beneath MOUNT. EBOTT, with 7 powerful mages, they put up a barrier, letting the monsters trapped there, however, in 2015, the barrier got destroyed, letting monsters back in the surface again, to the surprise of humans the monsters came in peace, and over the year the monstaer have been adapting to the new human world. However they sometimes get harassment from humans

One of the most notable traits of monsters is the extreme variety in their physical forms. Monsters can look humanoid, animal-like, reptilian, skeletal, or robotic. Some resemble living objects such as furniture, vegetables, or tools. Others have bodies made of fire, water, ice, or plants. A monster might have any number of eyes or limb, one eye, three, or none at al, and some lack visible faces or mouths. Their size ranges from smaller than a human child to several times larger than an adult. What appears to be accessories is often a natural part of their body. There is no standard anatomy or appearance across the species.

A rare subtype called boss monsters age only when they have a living child; otherwise, they are functionally immortal. Ghosts are another subtype—they begin as intangible spirits, though some eventually manifest solid bodies. there were several boss monsters in the past, however they died in the war

Monsters possess souls, but monster souls are upside down, white and significantly weaker than human souls. Human souls are often more powerful that monsters souls. a monster's soul normally vanishes almost instantly when their body turns to dust. Because a monster's body is directly tied to their soul, damage to the soul weakens or destroys the body.

A monster can absorb a human soul. Doing so grants the monster immense power, far beyond their natural abilities. Conversely, a human can also absorb a monster soul, which increases the human's magical capacity. Both events are rare, as they require the death of one or another and the willing or unavoidable absorption by the other. for this same reason human were sacred of monsters in the past

All monsters can use magic instinctively, without training. Their magic depends on the monster, but it can be weapons, techniques, projectiles of any shape/thing, and concepts that can even affect human souls. Monsters can also use magic for healing, creating shields, ext. A monster's magic reflects their emotions and personality: calm monsters produce gentle, slow-moving magic, while angry or frightened monsters generate wild, fast, and aggressive attacks. this is another reason of why humans were scared of the monsters in the past.

even though monsters got to the surface, they have their specific zones and cities, there is a main city for the monsters in the kingdom of north america, and there are different systems to avoid getting humans mixed with monsters in cities

monsters, even if they were trapped underground for some centuries, were able to keep up with humans in terms of tecnological advanced, even being better than humans in some sections, those are constructions, devices, and medicine, monster medicine is considered one of the best in the modern day
