The Wolf

The Wolf was one of the aliens whose DNA was absorbed into the Omnitrix, giving Ben the new alien, Benwolf. At first people thought that The Wolf was the Yenaldooshi, the wolf-creature of Bad-luck. But after a failed attempt of trying to destroy it with a sliver pendant, they realized that he was actually an alien. With similar powers to Benwolf, The Wolf also has the sonic howl. But the difference is that The Wolf's eyes and sonic howl is Purple in colour, whereas Benwolf's eyes and sonic howl is Green in colour. Later, the people realized that The Wolf was one of the aliens working for Ghostfreak. His mission was to control a network reciever in New Mexico.
