Vulpimancer

Vulpimancers are bizarre and beastly creature that is far more animal than humanoid. Bred for the hunt, Vulpimancers propel themselves through all sorts of terrain with the aid of two long powerful apelike arms. Vulpimancers have incredible athletic ability and heightened senses of smell, hearing and taste. And while they have no eyes, porcupine-like quills serve both as weapons and finely tuned sense receptors that can "see" in ways most other creatures can't. Super-adept, Vulpimancers can use their quills to detect the slightest movement, heat signatures and some even say, fear. Once prey is located, the quills on their backs can be fired off like projectiles, or the Vulpimancer can roll itself into a kind of spiked ball to attack its enemies. Having no eyes means that some enemies can get the drop on them fairly easily. Constantly on edge, Vulpimancers must be ready to fight because they have no way of communicating verbally in a humanoid fashion- just snarls and growls - only adding to the danger of "blind" situations.

Vulpimancers/Wildmutt are a species of alien in Ben 10. Several have been shown throughout the series but the most common is by Ben Tennyson through means of the Omnitrix. These species seem to be dog-like when young and become more feline like as they grow older. As in the original series, Ben's Wildmutt looked more doglike than the Vulpimancers shown in Episode 14, Truth, as these were shown to be bigger and more mature but also more catlike. The males gain stripes on their backs and both male (proven both when Ben faced 2 vulpimancers in the meat factory and in the Ben 10,000 episode, when Ben's older alter ego transformes into a vulpimancer) and female vulpimancers grows tails. In the Ben 10: Alien Force episode Single-Handed, it is shown that besides orange, they also come in different colors as there are 3 Vulpimancers that are gray/blue in color in this episode, this is possibly a sub-species.
