C'mon, if you don't know who this guy is and you're a Dragonball fan, you should probably crawl out from under a rock you've hiding beneath. Freiza is a of course the greatest villian to walk the face of the Universe. He's basically the head of a Huge "company" that goes around purging planets of life, and then  selling them to the highest bidder. Or, if he's so inclined and in the right mood, he may just wipe out a planet for fun. Freiza sees himself as the most powerful being in the universe, with no equal. However, Freiza's greatest fear was the lagedary Super Saiyan, and by wiping out all but 3 saiyans, he figured that he would have been safe Well, yeah he might have been, unfortunately he missed one, Goku. Freiza has the ability toupgrade his body actually changes to become suitable for his power. Once he powers up a third time, and each time he upgrades, his power. Once he powers uo a third time, he has the ability to charge up to 100% energy. Freiza is supposedlykilled by Goku on Namek; however he's found and rebuilt by his father, King Cold. He goes to earth to seek revenge, andthere he's sliced and diced by Trunks and goes to hell.
