I have a lot of human OCs, but my most favorite are the Number Brothers.
Nineman (the youngest) has no powers whatsoever and relies on firearms, but Tenman (the eldest) has an aura style called Apparition; which allows him to phase into people, vice versa, and the ability to have limited control of other peoples body parts by literally digging into their wounds.
The Number Brothers use their skills to commit crimes (primarily blackmailing and robbing people) across the monster populated Sunburn City!
