That giant boy who wanted to sail with Shanks, how much panel time do you guys think Oda will devote to him? If we were to go by Oda's trends, probably way too much.
Oda will probably make this guy out to be the next O-Tama/Momonosuke type characters. We'll probably spend a significant amount of time having Luffy befriend him and he'll probably have some plot relative power that makes him very important or something.
My theory. This guy is supposed to parallel Luffy, so perhaps he is a D. Maybe Saul's son or something. In addition, perhaps Oda could have him eat one of the god fruits, similar to Luffy and his Nika fruit and Momo and his Seiryu fruit.
