His skin is hardened to the degree that it is nearly impenetrable to ordinary forms of abrasion, including high caliber weapons fired from a distance. He also possesses an extraordinary amount of super-strength; for example, he was able to tear a bank vault door off of its hinges with minimal effort. He has demonstrated regenerative powers, allowing him to heal and restore lost limbs and teeth. He possesses superhuman reflexes and speed, especially while he is moving underwater. Killer Croc also has an enhanced sense of smell. Once he has become familiar with a person's scent, he can track them from miles away. He can see through his crocodile eyelids. As his appearance and personality has grown more and more bestial, his misanthropy has increased dramatically. He is jealous and hateful of "normal" people and often lashes out violently without provocation. As a result of these feelings of jealousy, Croc will often entertain himself by grabbing hold of small, pointy objects as a source of comfort.
