He is the reincarnation of Piccolo Daimaou. Right before the death of the present Piccolo's father, he had enough time to spit out an egg, which the Piccolo that we know today hatched from. His original intentions were to get revenge for his father and kill Gokuu as well as take over the world. After losing to Gokuu at the Tenkaichi Budokai, Gokuu told Kami-sama to spare him and went off to train so that he could defeat Gokuu. After five years, Radditz shows up and he finds that he is much more powerful then he is. So he decides that the only way to defeat him is by teaming up with Gokuu. When they confront him, they had a tough time but finally defeated him with Piccolo's Makkankousappou, with the cost of Gokuu's life. After the death of Radditz and Gokuu, Piccolo takes Gohan and trains him so that he could help with the fight against the other Saiya-jin's that Radditz mentions before he dies. Because of their long training together, he ends up being Gohan's protector and guardian. During the fight against Nappa and Vegeta, Piccolo while protecting Gohan from one of Nappa's attacks. During the Freeza saga, Piccolo was wished back to life and transported to Planet Namek. On his way to the area that Gohan was at, he ran into Nail, a fellow Namek-seijin and merged with Piccolo, making Piccolo a little stronger. During the Jinzouningen saga, he convinces Kami-sama, he was the God of the earth as well as Piccolo Daimaou's counterpart, to merge with him so that he could be stronger. I believe that after this merge, Gokuu called him Kamicollo for a little while.
