Diamante

Diamante is one of the main antagonists of the Dressrosa arc in the anime/manga One Piece. He is an executive officer who is apart of the Donquixote Pirates. He was the one who was responsible for the death of Rebecca's mother, Scarlet.

Personality
Diamante is a rather laid back individual who likes to get praised for his achievements and power. While he enjoys the attention, he usually likes to deny it to some extent like in some of his conversations with Donquixote Doflamingo. Diamante is also very arrogant thinking that he can obtain the Mera Mera no Mi in his battle against Rebecca, Jesus Burgess, and Lucy. He is shown to be down right sadistic as he mocks Rebecca for being weak and openly admitting to killing her mother. He also shows his sadistic side towards Kyros too when he found out that Scarlet was his wife. Despite his arrogance, Diamante has shown to care a lot about his team and his leader, Donquixote Doflamingo.
