NAME: Erza Scarlet
POWERS: The Knight - Summon and equip all sorts of melee weapons and armors, each armor serving a different purpose, one will increase her physical defense while other will increase her speed, there are also some that increases one specific elemental resistance and a special one that allows her to control floating swords aside from her own.
As for weapons they are just as diverse as the armors, but all of them are melee(she pretty much only summons swords and spears though, but there was one time she summoned a giant hammer), also some of them are imbued with some elemental property.
CHARACTER: Erza is a skilled and strong warrior, from the start of the series she's recognized by most as one of the strongest female mages alive. She has a very strong sense of justice and pride and also cares deeply for those around her, not thinking twice before putting her life on the line for her friends. It is also implied more than once that she's actually a very submissive individual when it comes to more intimate relationships.
Here we have a collection of pretty much all of the armors she summons throughout the series:
And here a fighting sequence that displays well her fighting style of changing to new armors and weapons one after the other(thought there's no need to watch more than 5 mins past the moment I posted it here, most of the rest of the fight are just flashbacks and talking).
