In MK1, Reptile was a mix between Scorpion and Sub-Zero, having all their move and having a green suit (Since Yellow + Blue = Green). In MK2, he only keeps Sub-Zero’s slide, as all his other move are new to the game.
True to his name, Reptile is a reptilian creature that is disguised as a human. His face is revealed during his Acid Spit projectile and during his first fatality. He is also able to turn invisible until hit or until he performs the move again to return visible. Lastly, he has a unique, slow Forceball projectile that causes his opponent to launch in the air, allowing Reptile to perform combo.
Against the CPU, Reptile will often use his jump kick + slide and his Acit Spit, when far. His invisibility is almost useless, since the CPU know where you are anyway, but it is required for his second fatality. Early in the game, his Forceball, following by two standing punch and a kick is his strongest move. His roundhouse kick is also very fast, allowing him to hit his opponent twice and even three times before he can fall down, but must be done in a corner. He shares that trait with Scorpion and Sub-Zero, since they share the same base character. It is also an excellent anti-air.
