Dayo's history

We'll start at the beginning, Dayo landed when he was a baby... He didnt really know why he was on earth, and he wasnt aggresive, unlike other pure sayans ... on the outside though, on the inside, he was wrekking havoc in his mind, his agression was killing him because it turned into a depression... He had unbelievable hidden powers, just like someone he met when he was 9... his name was gohan. He was a lot older than dayo but Gohan felt dayo's powerlevel... and decided to train dayo.....
