Despicable One Piece villains like Charlotte Katakuri and Admiral Kizaru are compelling enough to warrant a redemption arc.

Akainu is a major One Piece antagonist responsible for killing one of the most beloved characters, Portgas D. Ace.He is introduced in Chapter 397 as one of the Admirals, Akainu, which means Red ...

Akainu joined the Maine at an early stage of life, so he could have crossed paths with the Dragon. As Dragon betrayed the Marine, their relationship could be that of enemies.

Akainu is the man who killed Portgas D. Arc, and he tried to do the same to Luffy. The admiral despises anyone whose blood he considers bad, and those with the Will of D land in that category.

Sakazuki, also known as Akainu or Red Dog, appears as one of the main villains in One Piece. He is a former Admiral, who is currently serving as Fleet Admiral in the Navy.

Bandai Namco revealed in this week’s issue of Jump magazine that the three Admirals in Aokiji, Akainu, and Kizaru are joining One Piece: Burning Blood as playable characters.[Thanks, @Kazu4281.
