@Lobster:
I don't even understand why Oda said that Chopper's age was 15..
1. He doesn't act like a 15, nor sound like a 15 year old human. He's like a 5 year old kid (like Gash Bell, which his VA also plays)
2. Or if you go by Reindeer years, then he's already long been a full grown adult
Probably just so the Hirluk Timeline wouldn't be thrown off.
Well, in my opinion…
1. Chopper doesn't act like a 15 year old because he's been living amon humans for less time than that and has always been kept quite away from the human world. So basically, he's an awesome doctor, but knows nearly nothing of the human culture nor the world itself. In the medical area, his knowledge farly suppasses that of a human in his teens, but in life experience, he's still a child.
And Luffy doesn't act like a 17 year old eigther no matter how you look at him. Seriously Oo
2. Chopper IS a full grown adult reindeer. His real form is the animal form, not the cute little furry thingy he usually is. If you see how he looks like in Movie 3's credits and how his 'human' and "half-human" form looks like in any picture of the Strawhats as children or when he met Hiluluk, it seens to me that only that form growns up at all.
I still think chopper will end up cuddled, hugged and loved to death by eigther Porsche or Perona =w=
