well at city of heroes, i play the role of a defender. my origin is mutation, so i'm a mutant and my powers originate from my genes and inheritance. defenders' primary job is to defend other heroes, healing them, giving them offensive buffs and de-buffing villains. defenders can stand alone fighting villains as they have long range fighting powers, but would need other archtypes in mishes and taskforces. defenders are popular and they are often in need by other archtypes.
