Spoiler One Piece Chapter 992 Spoilers Discussion

[Bounty]

It sort of makes sense with his attack names so far (at least Thunder Bagua). We gotta see what Oda does because I'm not even sure how he can represent these "elements".

However, we've barely gotten named moves from Kaido and the longer this fight goes on, the more we'll see.

What makes it really intriguing is the involvement of lake and water elements just in case it turns out that he is a non-DF user and there are some weird shenanigans of him originally being a dragon. Like many have speculated this could justify as him being the strongest in the sea too (alongside land and air).
I'm personally skeptical of this because of Yamato's existence, but we'll see.
