What seems like a running gag actually has some truth to it, asHawks' magical power level is rated as a measly thirty, but because they are from the realm of Pergatory, Hawks has more weight behind his claim. Due to being from Pergatory, Hawk is extremely resilient and additionally possesses the power to absorb the powers of things they eat.
