Killer Croc, like all other interpretations of the character, is a massive human-crocodile hybrid, with scaly green skin, long and sharp black fingernails, yellow eyes with vertical black pupils, and an under bite with several sharp teeth showing. In episode 1, he is seen wearing the typical orange Arkham Asylum prisoner uniform complete with the black logo on his chest. When at the Legion of Doom, he can be seen wearing a grey tank top and tattered brown pants.
