Transpork

is Hawk's inherent power. It gives him the ability to take on the traits of any magical creature he consumes.

Description
Whenever Hawk eats (part or whole) a magical creature, he will gain the same power and traits as the creature, even gaining a similar appearance. The transformation will wear off once Hawk empties his bowels, flushing the source of magic from his body.

Trivia

 * In the anime, this ability is slightly renamed as Trans Pork (, Henshin (Toransu Pōku))
