Piccilo is a cool guy. He is the evil half of Kami and he used to fight with Gokuu a lot. But once Radditz arrived on Earth, Piccilo and Gokuu teamed up. In the end, Piccilo shot a special beam cannon at Radditz, who couldn't dodge it because Gokuu was holding him. The only reason that Piccilo fought with Gokuu was because he was evil. After Piccilo and Gokuu teamed up to defeat Radditz (and Garlic Jr.) they slowly became more and more of a team (much like what happened with Vegeta. When the threat of more Saiya-Jins was present (Nappa and Vegeta) Piccilo took it upon himself to train Gohan. Piccilo was the one who really took the first step to revealing Gohan's hidden powers. Piccilo has also saved Gohan many a time. Piccilo's special attacks are the Special Beam Cannon, his Extendo-Arm move and his regeneration.
