does anyone know a Аниме where the chick is really badass and has a reallly cool power but isn't the main character?

ikaros from heavens Остаться в живых property is.

Yamraiha from Magi.
Has water magic.

FMA has quite a few, like Izumi and Sloth and Lust.
Durarara - Celty(Would she be considered a main character?)

Temari from Наруто is so cool and badass but sadly we rarely see her. She has the Wind Release nature and can summon Kamatari (the one eyed weasel) with her Фан to cut up her opponents. She's blunt and not afraid to speak her mind and is в общем и целом, общая a really amazing character.

Hancock from One piece is a badass character, she is one of the 7 warlords (they're very strong pirates) and she isn't a main character.

Alice - Pandora Hearts.

She isn't the main character, but shes always with the main character, and plays a huge role in the anime. If Ты have seen it, Ты will know what I mean.

Rangiku Matsumoto (Bleach)

Ishizu Ishtar from Yu-Gi-Oh!

Kunieda from Beelzebub
