Ultimate Wildmutt is the Ultimatrix's DNA sample of an Evolved Vulpimancer.


Ultimate Wildmutt is significantly larger and more muscular than Wildmutt. His fur is a maroon-red color and he has four huge gray/white spikes running down his back that overlap. These spikes start out as a shark-like fin at the head and rises almost into an arc over the back, tapering near the rump. He also has a long tail with a curved horned tip, resembling a scorpion stinger. His lips are black, like Wildmutt in the original series, and he has white claws.

Ultimate Wildmutt wears the evolved Ultimatrix symbol on his chest.

Powers and Abilities

  • Enhanced Strength
  • Sharp Teeth
  • Bipedalism

Ultimate Wildmutt has Wildmutt's incredible sense of smell and is physically stronger than him. He also, unlike Wildmutt, has the ability to speak.

Ultimate Wildmutt has more agility than Wildmutt and in addition to his enhanced smell, he has enhanced hearing as well as a sharp tail, claws and teeth used for close range combat.


Like his base form, Ultimate Wildmutt cannot see and his vision is only made up of a dull 3-D mapping.
