Ultimate Wildmutt

Ultimate Wildmutt is the evolved form of Wildmutt. Not much is known about him, except that his appearance was confirmed by Bandai during a toy fair.

Appearance
Ultimate Wildmutt is significantly larger and more muscular than Wildmutt. His fur is a maroon-red color. He has small, fin-like growths on his shoulders and his chin is much larger. His quills are gone, and have been replaced by 3 huge gray spikes on the back of his neck. He now has a small tail with a gray spike on the tip of it. His teeth are now slightly larger. His claws are now gray. unlike original Wildmutt, Ultimate Wildmutt gains the ability to talk, which is likely the result of its evolution.

Trivia

 * Ultimate Wildmutt is the second alien that evolved from an alien in the original series (the first being Ultimate Cannonbolt) and the first of the original 10.
 * It was shown at the 2011 Toy Fair that he can talk which is strange since his original form can't. However the forms ability to talk is likely due to it being an evolved form of Vulpimancer/Wildmutt.
 * His appearance looks similar to a Fel Hound from Warcraft.
 * It is confirmed that sometime in a future episode, Ben will be as Wildmutt, pressing the Ultimatrix for another alien, he will turn Ultimate by accident.
