Ultimate Wildmutt is the Ultimatrix's artificially evolved DNA sample of a 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[]

Unlike his devolved form, Ultimate Wildmutt has the ability to speak other languages than the Vulpimancer language.[1]

Ultimate Wildmutt retains Wildmutt's incredible senses of smell and hearing.

Ultimate Wildmutt has sharp claws and teeth, which can be used for close range combat. He also has a scorpion-like tail with a sharp tip.[merch 1]

Ultimate Wildmutt possesses enhanced strength, as he was easily able to hold down Prisoner 775.[1]

  • Ultimate Wildmutt is the last Ultimate form used by Ben on-screen in Ultimate Alien.
  • Ultimate Wildmutt's sentient counterpart did not appear in The Ultimate Sacrifice, even though the synopsis said that all of the Sentient Ultimate Forms want freedom.
  • Ultimate Wildmutt was the first Ultimate Form to be hinted on the DVD cover of Ultimate Alien named The Wild Truth, where his view is shown, with Ultimate Wildmutt facing away from Ben.
  • Derrick J. Wyatt did concept art for Ultimate Wildmutt as part of freelance work, who used inspiration from looking at dinosaurs. However, none of his designs were used for the final version.[DJW 1][DJW 2]
    • One of Ultimate Wildmutt's unused concept art by Jon Suzuki would later be repurposed as the basis for Solid Plugg's design.[DJW 3]
    • Strangely, Ultimate Wildmutt's final design bears a striking resemblance to the Godzilla franchise monster, Titanosaurus, with a red body with a white-yellow frill running down its back and onto its tail.
  • The Omniverse crew did not discuss bringing Ultimate Wildmutt back.[DJW 1]
