Perseus

Full name, Perseus Abaddon.
Perseus has the ability to manifest void from thin air. Everything the void touches slowly gets consumed and disintegrates. Apart from this, within the void is a great shade beast that has a million eyes and a million voices. Perseus is able to control the void beast and uses it to spy on targets. But due to how fatal this ability is, he has only ever used it twice, and when he did, it was not a pretty sight. He doesn't exactly know what would happen if he pushes himself from using his full potential, as he was only told by "someone in his dreams" that he will perish if he does. In the meantime, Perseus remains dormant and is laying low.
