Mob

Mob body is made of shadowy goo, it's acting like a shadow, being unable to be where light is to hard, and will actually run away from light, but if you touch it in the shadow, it will fell like a strange slime, as it clearly is humid but will not leave any residue. His body can be this shadow liquid, or form into a more humanoid form.

Even if all his body is clearly black, the only non-shadow part of his body are his eyes, two yellow orbs that usually betrays his position, so he past most of his time hiding them inside.

Mob power allow him to 'fuse' with the shadows, and store item in his own body, trapping mostly anything that doesn't produce light. as a resulte, his body mass increase propotionnaly. When he don't have anything inside his body, he can fit in a demi-liter bottle.

Mob has a big problem with being social in general, he fell akward and, most of the time, will act very strangely and dramaticaly, trying to 'fit in'. As a result, he is unaware of when people are trying to manipulate him.

He need a model, someone to follow, and more generically someone that can tell him what to do.

His Quirk being one of the reasons he'll never properly fit in society, he devellop an belief that power build the person, and it can't be any other way, heros are heros because of it, and vilains are the same.

When tend to stalck people, hide in their home or personnal stuff, just to see, and somehow fell like being a part of their life.

He also work a lot on impulsivity, if we want something, he will just drop anything he was doing and go get it, and most of the time he will get so excited about it, he will forget what it was about.
