Wildmutt

Wildmutt is the Omnitrix's DNA sample of a Vulpimancer from the planet Vulpin.

Appearance
Wildmutt appears to be a huge (the size of a car), orange dog with no eyes, ears, nose, or tail. His teeth are very defined and stick out of his mouth. Wildmutt has no eyes, instead using his sense of smell and hearing, which are aided by three gill-like nostrils located on each side of his neck.

In the original series, Wildmutt wore a brace with the Omnitrix symbol on his left shoulder.

Four year old Wildmutt looks very similar to his ten year old self, but a lot smaller and thinner.

In Ultimate Alien, Wildmutt wore the Ultimatrix symbol on his chest and has orange lips rather than black, also he had lighter fur, however he had black lips in the Ultimate Alien Intro.

10-year old Wildmutt in Ultimate Alien is almost identical to his 10-year old version in the original series, just with orange lips rather than black and the brace doesn't have any white in it. The Omnitrix symbol is also recolored.

In Omniverse, 16 year old Wildmutt has black lips, his forearms are a bit bigger and he now wears a green and white collar which contains the Omnitrix symbol.

Powers and Abilities
Wildmutt has a superb sense of smell. Due to him not having any eyes, his "vision" is made up of a dull 3D mapping of where his scents originate.

Wildmutt can track almost anything and anyone by their scent.

Wildmutt has superhuman strength, as he can rip off the roof of a car with ease.

Wildmutt has enhanced agility that allows him to run, jump, as well as climb at a superhuman rate.

Wildmutt can dig deep craters at a fast speed.

Wildmutt is a quadruped, however he is capable of standing on his hind legs, and he can punch, somewhat awkwardly, by doing this.

In Ben 10: Omniverse Wildmutt could release a sonic attack capable of stunning enemies.

Weaknesses
Wildmutt can't talk. Instead, he communicates through a combination of barking and snarling. Due to this, it is extremely difficult for anyone to understand him.

Wildmutt's senses are very sensitive, making him vulnerable to anything that can overwhelm his senses such as a high-pitched sound or a strong smell.

Wildmutt's lack of eyes makes him completely dependent on his other senses (mainly olfactive).

When infected with a cold, Wildmutt's nostrils (on the sides of his neck) get blocked by mucus, making him unable to smell or hear and rendering him essentially "blind". In addition, his fur color seems to "decrease" from its vivid orange to a pale yellowish-orange tone, and his lips and claws turn from black to a sickly dark green hue.

Trivia

 * According to Dwayne McDuffie, Vulpimancers do have a language, but it is too difficult for Universal Translators to translate. Wildmutt doesn't know it.
 * Wildmutt's name in the Croatian version of the cartoon, "Psina", means "Great Dog", but the same word is sometimes used to name several sharks, especially the Great white shark, which sometimes caused naming confusions between him and Ripjaws.
 * In the opening of Ben 10: Ultimate Alien, Wildmutt's lips are black instead of orange.
