The Creeper has the ability to regenerate any part of his body by devouring a similar part from a victim. In this manner, he has survived since Biblical times, replenishing his deteriorated body by feeding on humans for replacement parts. The ability also works as a form of healing factor, as the Creeper can discard injured or maimed body parts after ingesting a replacement version. In addition to his regenerative powers, the Creeper is quite resilient. In the second film, it is impaled with harpoons multiple times yet retains the ability to move, including several head wounds. The Creeper only stops moving when it reaches its hibernation period.
Physiologically, the Creeper is a humanoid figure. His skin is dark green and yet scaly, and he has razor sharp claws and teeth. Hidden under his black duster coat are a pair of enormous bat like wings strong enough to lift himself and at least one adult human. In the second film, the Creeper is shown to throttle a pick-up truck off the ground while in flight. The speed at which he can fly is undetermined, but he is seen to match a speeding automobile with little difficulty. The Creeper possesses a third nostril on the bridge of his nose which allows him to smell specific organs in his victims. This second sense of smell can only detect essential parts when the being is in a state of fear.
The Creeper is a sort of a Chimera. The human body parts are backed up by a second, almost indestructible creature that does not seem to be the product of any Earthly line of evolution. This second creature forms the wings and clawed hood structures behind the humanoid head of the Creeper.
The clawed hood in both movies to date can flare out to intimidate/frighten the Creeper's prey. At the end of the second film the clawed hood engulfs the Creeper's head as the creature returns to a 23 year hibernation. In Jeepers Creepers II, the creature is seen to discard and replace his head with one from a fresh victim, but the clawed hood remains part of the original torso. Therefore, the clawed hood/wing structures appear to be the actual Creeper and the human body parts appear to be additions. It's unknown if the Creeper can get memories or knowledge from a freshly absorbed human head.
The Creeper has superhuman strength and speed. He is strong enough to tear apart automobile frames and rip parts from the human body barehanded. He can also climb on walls like a spider, and is well-versed in physical combat, including using melee and throwing weapons. While the Creeper does not talk in either of the films, a deleted scene from the first film has him speaking a line in an American accent saying, "She don't smell too good... Darius.". He is also known to whistle the Jeepers Creepers song. The Creeper in the first film has an old phonograph in his new lair, and seems to like early 20th Century music and songs, hence the film's title Jeepers Creepers.
