Overhyping a dragon Zoan? I dunno.... I mean, just look how powerful Lucci was, and he's a
leopard (those cats are pretty unremarkable when compared to lions or tigers). I'd imagine that a dragon Zoan would be pretty darn scary, especially if the user in question is no slouch in combat, either.....
...Of course, that's only considering if that particular Zoan type
does appear in the series at all. But it's definitely possible if we've got
dino fruit users appearing now. Plus, we could use more reptilian-type Zoans anyway.
