Ok so I posted this one a little later than in the month than I posted my other year of the dragon pics, but in my defense I wanted to finish the Wano arc in One Piece to make sure the information I describe here is accurate. With that being said-

**SPOILERS FOR ONE PIECE, PLEASE ONLY READ IF YOU'VE SEEN THE WANO ARC OR YOU DON'T CARE ABOUT SPOILERS**
So from the moment I saw Kaido, I knew he was going to be my favorite villain in One Piece, and as I saw more and more of him as the series went on, that feeling checked out. He's so powerful, being able to keep up with and hurt Gear 5 Luffy for a time, that he's less like a character and more like a force of nature. Though power aside I found it funny that he got drunk in the middle of his and Luffy's fight, and his drunken attacks are very effective, hell even before his epic fight with Luffy on top of Onigashima, he one-shot Gear 4 Luffy with one drunken swing of his weapon, and to put that into perspective- Gear 4 Luffy is so powerful in Dressrosa he unleashed a punch that folded a huge part of a kingdom on the island like an omlette. I could go on and on about how powerful Kaido is, but I'll just cap this off by saying that his attack Thunder Bagua is one of my favorite attacks in One Piece, it's up there with Ifrit Jambe and pretty much any of Jinbei's attacks, I would say it's crazy to see him go, but the thing is there are a number of scenes in this show that really looks like they kill off a character only to have that character be fine later, even in the Wano arc, so who knows, maybe him and Big Mom will come back at some point, only time will tell.
(quick note- if Kaido is definitively proven dead or alive in the manga, please don't spoil it, I'm not an anime only but I am currently in the process of collecting the manga, and I'd rather read for myself.)
