User blog:The Bonehead Skipper/Chopper's Devil fruit

We now know that the Human Human fruit has different models. But as we all have probably noticed Copper has never turned full human. His heavy point, which is supposed to be his full human form his furry and commonly mistaken for an ape. I saw somewhere on arlong park's forum that someone thinks that it could be a caveman model. After thinking about it it could be true, it could be an ancient zoan. What do you guys think?
