One Piece - The Legend of the Crocodile

In the slums of Fishman Island there was a small boy that appeared to be 4 years old, he looked like a mix between a crocodile and a human, but the most interesting part about this boy is that he had four arms.

This boys name is Asura, he was dumped into the slums of Fishman Island called the Fishman District which is the most dangerous and poverty ridden area on Fishman Island at the age of 3, Asura was the product of Queen Otohime and an unknown person, while she was married to King Neptune.

Asura was always a intelligent and cold child, he realized from a young age if his mother married King Neptune, he would get rid of him.

Luckily Neptune underestimated how resourceful Asura is, even at a young age he would always be on guard, because he was an illegitimate child of a women of great political importance, so just in case he was kidnapped or worse threaten to be killed he would be ready.

Asura will not forget where he came from and who his mother is, but for now the only goal is, to survive the hell hole that is the Fishman District.
