a green facial mask as part of his ninja disguise to conceal his true reptilian nature, removing it for his acid spit attack (which was Daniel Pesina's idea inspired by an episode of The Amazing Spider-Man) or his tongue grab Fatality. Reptile stands 6 feet (183 cm) tall, and speaks in a hissing tone. In Mortal Kombat 4, Reptile's appearance became more reptilian, with his head completely uncovered. His hands became clawed, while his feet were now three-toed talons; it is likely that the authors were inspired by the appearance of the dinosauroid conceived by the well-known Canadian paleontologist Dale Russell. By Deadly Alliance, Reptile had developed a full reptilian head and tail, with gold and black armor to cover his legs, elbows, shoulders, and belt, and his shoes go off, he was completely barefoot. Bone spurs extended from the base of his skull down his spine, ending at the tip of his tail, while a similar spur extended from his heel on each bare foot. Ed Boon described the changes to Reptile's design over the course of the two games as hinting at him "evolving into a bigger character", and foreshadowing Onaga controlling his body in Deception.

In addition, black strips of cloth wrapped around his forearms, hands, and head, leaving his eyes, mouth and bare feet exposed. The design was later reused as his primary outfit in Armageddon, with his appearance from Deadly Alliance serving as his secondary outfit.

His Forceball attack creates an energy ball from his hands, while his Acid Spit attack produces a higher, faster projectile. Reptile can slide towards the opponent, or turn invisible for a brief period of time or until
