Wildmutt

Wildmutt is a Vulpimancer (a play on vulpine, which means fox) from the garbage planet Vulpin, an animalistic creature that fights with animalistic speed and strength yet unable to speak. Though without eyes, Vulpimancers use the gills on their neck for thermography echolocation and use heightened senses of sound and smell. However, a loud sound or a horrific smell can overwhelm a Vulpimancer. According to various profiles on Wildmutt, the porcupine-like quills on his back supplement his radar sight and can also serve as weapons, either protecting him while he's rolling, or as projectiles fired off at will. This ability is unique to adult Vulpimancers, and since Ben's version is only ten years old, these quills have not fully developed.


Ben first transformed into Wildmutt in "And Then There Were 10" after his experiment with the Omnitrix, thus his first intentional transformation.When Ben got his cold, it affected Wildmutt by clogging its nostrils, causing it to lose its sense of smell, therefore, not letting it "see." In Ben 10: Ultimate Alien, Wildmutt's design was basically unchanged, except that his lips were orange instead of black and he has Ultimatrix symbol on his chest. Wildmutt made a few brief appearances in the third series, most of them off-screen and not by Ben; his official debut was in "Prisoner #775 is Missing", where he used to track the invisible alien prisoner, and as he doesn't speak, Gwen shout out his name for him. Wildmutt made a brief appearence in "Inspector 13" when the Ultimatrix malfunctioned and Gwen and Kevin transformed into the aliens, Kevin transformed into Wildmutt and crashed his car.


In Omniverse, 16 year old Wildmutt has black lips, his forearms are a bit bigger and he now has a green and white neck brace. The Omnitrix symbol is on his 'collar'. 11-year old Wildmutt looks identical to his original design except that the Omnitrix symbol is green. He first reappears in "Have I Got a Deal for You", chasing the Screggit.
