Thornhounds are a species of plant-like aliens featured in Ben 10: Protector of Earth.

Appearance

Thornhounds are plant-based aliens with a dog-like appearance, having four legs, no visible eyes, a long tail, and a body covered with thorns, hence their name.

More mature Thornhounds, such as Thornhound Aggressors, have more pronounced thorns and a large frill extending from their mouths.

Thornhoud Chargers are brown, with yellow face, light brown spikes and two long tusks that are near their mouths.
