Porcupine

porcupine is first seen in the episode" ready to rumble", where he fights gatorboy, one of ben's alien, for the 911 grand prize money. apparently, gatorboy always won, until the day he met ghostfreak, vilgax and kevin 11, which he zaps his transmodulator to combine himself with them, to make vilghost 11. vilghost killed gatorboy, but then, the omnitrix turned ben into...the awesome eye guy, so he downloaded the vilgax, kevin's, ghostfrek's and porcupine's dna, giving him an ectonurite, a chimera sui generis, an osmosian, and a mutated porcupine. he is fling off earth by vilghost, which at that point, he becomes vilgax, and challenge 10 worlds, with his lackey psyphon.(maybe this is true, or not....)
