Pell said there are 5 Types of DFs that grant Flight (Do not Count Variations)
We've seen:
Bird DF (Alongside it's Multiple Variations) such as Pell or Marco
Insect DF (Alongside it's Multiple Variations) such as Dwarf Duo
Dragon DF (Alongside it's Multiple Variations) such as King
Bat DF (Alongside it's Multiple Variations) such as Stussy or Non-Canon Patrick Redfield
It's Common Knowledge that in our World, Only Birds, Insects, Pterosaurs & Bats have Natural Ability to Fly
So i believe Laffitte should have 5th Type of DF that grants Natural Flight (Wings)
I'd say it's Angel Angel No Mi
