Kame
Kame is the good side of Piccolo. It might sound weird but as a youngster, Kame wanted to be defender of Earth but the current defender said that he could not because his heart was not pure so he trained hard and got rid of his evil side making Piccolo. In the series Kame just stands in his lookout watching all the battles with Mr. Popo. He does virtually nothing except get trapped in a bottle by Garlic JR. and get beat up by the former defenders of Earth. In the new series, he reluctantly refuses with his evil side Piccolo in order to defeat the androids 16, 17, and 18. After the fusion, Kame is never seen again.
