Wonderweiss vs starrk

Wonderweiss has some weird feats. Blitzed ukitake and one shot him while losing to mashiro. Then getting his butt kicked by kensei but then beating his masked bankai in resurrection. he then slightly damages yamamoto which is an insane feat.

Starrk starts off decently fighting on par with kyoraku albeit his sword was not in the mood. Gets a point blank cero off shunsui but then heavily struggles with shikai masked vizards needing to bust out his wolves. Shunsui then gets a hidden stab off of him and proceeds to beat him.
