Making your allies able to ride you, or be carried by you. The main zoans i really would like to be able to use this are the tori tori no mi model Phoenix and the Ryu Ryu no mi model pteranodon (I’m pretty sure this got added for pteranodon since I originally made this post, I haven’t tested it but if it still has that time limit it’d be kinda whack if you accidentally dropped ur df user friend in the sea). Marco is always carrying ppl in the anime. And having the ability to assist your allies that have eaten devil fruits over water would be super useful. I think maybe the birds should be limited to one “passenger” tho.
