User blog comment:The Bonehead Skipper/Chopper's Devil fruit/@comment-2229670-20101106195132

He never has a human form. Except that Gorrila like form.

I don't understand how the Rumble Ball affects his Devil Fruit powers... cuz Jump Point ... Guard Point... Horn Point -> theese aren't human abilities(I think)

I think Rob Lucci actualy transformed in to a leopard... so at some point Chopper will transform in something like this: http://www.youtube.com/watch?v=ZAQLp77yzlE :))
