I suspect none of them will have regular zoans. This is purely on the basis that those are typically far weaker than ancient and mythical Zoans
We know the following:
Drake - Ryu Ryu no Mi Model Allosaurus
Page One - Ryu Ryu no Mi Model Spinosaurus
There are some potential hints for the other flying six:
Sasaki - If Kaido's tattoo and Drakes scars are anything to go by, his wing/feather tattoos imply a tori tori model fruit
Ulti - She behaves like a Geisha and has many cultural references, I actually think she could be based on a Rokurokubi and so have a hito hito model or a paramecia that revolves around an elasticated and impossibly strong neck
Whos Who - I just think of an owl based on his appearance and name, but the game he's named after is about identity, so could be a superior version of Bon Kurei's fruit - maybe one that mimics/steals abilities
Black Maria - Black Maria may be a reference to the Queen of Spades or Black Mamba snakes, so a burrowing animal Zoan - maybe a Naga fruit?
There's a chance some don't have Zoans or fruits (I don't think Sasaki will have a fruit, just a hunch), but this is in the instance they all have fruits.
I would love for the Tori Tori no Mi Model Nue to be real, and if it is, it must be a Tobbi Roppo member
