I still can't believe that Queen got a trashy zoan power like that.
At least a mythical zoan would be hella cool. King's zoan is similar to Rodan and thus, it clearly fits King.
I sorta get what Oda was going for.
King — comes from an unseen flying race, has a powerful ancient zoan
Queen — Human who possesses an ancient zoan of one of the largest living animals ever
Jack — Very strong fishman
Land, Sea and Air sort of thing that ties in with Kaido's
introduction.
And I love the idea of a sauropod being an ancient zoan. But I just don't know how Oda's gonna make that an interesting power by itself. Haki, plagues, all that will be cool. But just being big on One Piece hasn't meant much since Dressrosa, when Luffy could casually take out giants.
