Demo

Demo is a psycho-evolve. They're also a special type, and so have special abilities. One of them is their Demonstration ability, where before enemy attacks, Demo sees everything paused, they cannot move, and a yellow glow of like a ghost of the enemy making their attack, then Demo can successfully counter-attack or dodge their attack. This, however, does not work with bullets, and only attacks a human eye can see. They have a powerful reaction time because of this. Demo is also a special-type because they can "evolve" in different forms and stages. Each stage is achieved from the enemy being powerful or Demo getting way too angry. The higher he gets in the stages, the harder it is to achieve the next stage.

the first stage is Hatred, then Psycho, then Nightmare, then Psychotic, and finally the Absolute Psychopath. Each stage makes their strength and power much stronger, however, if they break the limit and go a stage beyond Absolute Psychopath, they break their limiter. This stage is called Isolation and is the deadliest as Demo now can do as much damage as he wants, however, this only lasts few seconds to few minutes. After each stage, Demo is unconscious, but for different times depending on the stage, they were at. 1 - 3 minutes of unconsciousness in Hatred, 6 - 12 minutes in Psycho Form, 15 - 18 minutes after Nightmare, 2 - 5 hours after Psychotic, and then 2 - 10 days after Absolute Psychopath. After Isolation, however, it is unknown.

Demo owns an illegal portal dimension gun. He is also a world destroyer so if he wishes too he could destroy the world he currently is on right now and just travel to another dimension, making his actions meaningless.
