The Gargoyle has a number of superhuman powers derived from the demonic body he possesses. His leathery skin is more durable than human flesh, and is able to withstand ballistic impact up to and including .30 caliber armor-piercing shells. His body is impervious to disease and aging. His speed and reaction time are equivalent to those of an average human male in his twenties, as is the acuity of his senses.

The Gargoyle's original spirit had considerable knowledge of magic. Christians himself was a student of the occult. But apart from being able to summon minor demons he has little magical ability.

The Gargoyle's rudimentary, featherless, scalloped wings, which span 5.8 feet from tip to tip at full extension, are insufficient in and of themselves to bear him aloft. The real mechanism of flight was a mystical power of levitation. His wings simply help him maneuver. The Gargoyle is able to support his own weight plus 100 pounds of cargo; he can fly at speeds up to 25 miles per hour. He is able to fly about 3 hours before he tires appreciably and has to alight.
