Ultimate Wildmutt is significantly larger and more muscular than Wildmutt. His fur is a maroon-red color. 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 whose tip has a horn, resembling a scorpion stinger. His lips are black, like Wildmutt in the original series.
Ultimate Wildmutt wears the evolved Ultimatrix MK10 symbol on his collar.
