Komodai was a male Saurian who invaded Earthrealm. He was very similar to the character Reptile.
It is not known where he originated from except that he was accompanied by a team of fellow Saurians that broke through a dimensional portal into Earthrealm where they fought the Earthrealm warriors. He would fight against the Special Forces Agent Jax Briggs but was defeated, though he managed to use his acid to damage his robotic arms.
Komodai unmasked
Komodai would retreat back through the dimensional barrier but swore to avenge himself. He returned to Earth and captured Sonya Blade in order to fight Jax once again; he and she may have conversed before Jax showed up, because she imparted to Jax the knowledge that Komodai's "in the gator family and that Jax could out-think him". Despite his plan and hostage, he was defeated once again which ended his threat to Earthrealm. He was sent back through the dimensional barrier to whichever realm he came from.
Behind the scenes[]
Komodai was created as a replacement for Reptile, who had perished in his battle with Liu Kang in the first movie as Defenders of the Realm takes place within continuity of the film. Komodai also seems to have a sense of honor, as he bows before his first battle with Jax.
Mortal Kombat: Shaolin Monks, Part II[]
Komodai, as well as his Saurian army, were stragglers escaping Outworld during the Shokan/Centaur scrimmage. The defenders of Earth were thrown into the mix, and he was about to have his way again utilizing his acidic tongue in incapacitating Jax and disabling his bionic arms. He was then hit from behind by Kung Lao's razor-brimmed hat and challenged the monk! It was a gruesome battle, and he nearly had the upper hand with his invisibility, acid, and energy projectiles; however, it wasn't enough for the resilient warrior! As his stamina was failing him, Lao knocked him to the ground, before he was split in two by his hat functioning as a buzzsaw!
Final Kombat[]
Just like with Reptile, they returned to overthrow the benevolent chameleons governing the Saurian race, and he was a formidable opponent for Jax till he was bested by Cyrax. The Chameleons bested him and Reptile in kombat before they were incinerated by the firestorm conjured by Blaze and Fire God Liu Kang.
