Aokiji is one of the members of the Blackbeard Pirates, despite having been a very well-respected Marine at one point. After the capture of Captain Koby, Aokiji ended up fighting against his former teacher, Garp, and this gave rise to one of the very best clashes that fans have seen in One Piece so far.

He’s also one of the most relevant characters in the final Saga of One Piece, as evident from the latest chapters of the series. And I am convinced that Aokiji is pulling the Severus Snape with this latest chapter.

He is trying so hard to gain the trust of Blackbeard by spilling marine secrets like Sword, which by the way even make Aokiji look like a traitor, and now fighting his former teacher Garp in front of Shiryu and CO.

Knowing him, I see no clear motive as why he should be considered a real 1Oth Titanic Captain and a bad guy, when all he ever did were “good” deeds, saving Saul, Smoker or Robin (multiple times). It would be so out of character for him to swap teams and become a villain.

After Akainu took the reigns, Aokiji said he didn’t want to work with the marines while Akainu was on top, so he maybe came to Garp looking for options, how to still be of help and this was the best outcome.

When Garp yelled “and never forget, you are ALL the future of the marines!!” I think he incluced his former prodigé Aokiji, and Aokiji knows it but he has to play along. Also maybe farfetched but when he froze Garp’s wound to stop the bleeding, for me it looks like he also froze his tears.

Maybe I’m missing something but this theory of him being bad is as bad as Zoro grabbing Luffy’s bounty when he becomes the Pirate King.
