I know alot about OP but i never knew when and who confirmed the Shichibukai Jimbei.Can someone tell me when was it mentioned in the anime/manga that he was a member?

Black is a better color for this forum in my opinion.

kuma Kuma fruit
Type:Zoan
Description:Allows user to transform into Bear like Human (Similar to Lucci's fruit).P.S. Bears are tougher then leopards…

What are your theorys/predictions on the "New Era" that Donquixote Doflamingo mentioned after killing Bellamy?

@Pass:

Hola y recepción. I take it by your avatar that you're a luffy fan.

Yeah i am a pretty big fan

Subjects can really change quickly…

I think Lucci is,he pretended to be friends with paulie,iceberg etc for all of that time. And as a child saved and killed those knights,also he told luffy that he would chase Robin to the end of the earth and kill her despite luffy's effort.
