Blitzwolfer

Benwolf is the Omnitrix's DNA sample of a Loboan from Anur Transyl's moon, Luna Lobo.

Appearance
Benwolf's appearance is based on a classic werewolf. He has grey fur and a long flowing mane and large bushy tail, with three sharp claws on each hand. The inside of his mouth is green. Benwolf wore the Omnitrix symbol on his stomach in the original series.

In Ultimate Alien, Benwolf's mane and tail have turned black. He retains the same clothing from the original series, the inside of his mouth is now red, his mouth is now white and he wears the Ultimatrix symbol on his chest.

Powers and Abilities
In addition to his formidable claws, fangs and muscles, Benwolf can emit a strong and destructive green-colored glowing visible ultrasonic howl if the parts of his quadra-hinged muzzle are opened and a shout is released.

Benwolf has enhanced senses of smelling and hearing.

Benwolf is the only Loboan seen able to speak.

Weaknesses
Like real-life canines, Benwolf is colorblind.

Ben 10

 * Benwolf first appeared in Benwolf. After the Omnitrix was scratched by the Yenaldooshi, it got stuck between Active Mode and Capture Mode, making Ben turn into Benwolf slowly. Wes thought Ben was turning into a Yenaldooshi because he was bitten by it as Wildvine. However, after the Omnitrix symbol appeared on his stomach, they realized that they were dealing with an alien werewolf. Benwolf turned back to Ben after he dropped Max and Wes on a cliff.

Ultimate Alien

 * Benwolf was re-unlocked in Ben 10,000 Returns by Ben 10,000.
