They are paired together as a double-boss. They can team up in their attacks in the SNES version; one of their moves involves Tokka withdrawing into his shell and Rahzar hopping on top and riding around the screen chaotically like a skateboard. Their low intelligence from the movie is also included in the game: they will often accidentally hit each other instead of the player, and will take damage for it. Just like in the movie, when the player defeats them in the game, they de-mutate to normal animals. It is possible to attack Rahzar after he has de-mutated. He makes a 'Yelp' sound. Also, in the game, their names have the spelling of the movie, not the later spelling of the TV show. The Super NES version borrows a quote from the movie which Tokka and Rahzar said, right before the fight: "Master say have fun." "FUN!" In the movie, they say this when they're tearing up a backstreet to lure the Turtles into a confrontation. Rahzar also made an appearance in the NES game Teenage Mutant Ninja Turtles III: The Manhattan Project. Rahzar appears in the Technodrome level immediately before Shredder, and uses an ice breath attack. Also, in this game Rahzar's name is spelled Rahzer.
Rahzar returns to the role in the 2009 -Turtles in Time remake for Xbox LIVE Arcade and PlayStation Network. In The Manhattan Project Rahzar has ice breath, and curiously has fire breath in the Super Nintendo Version of Turtles in Time.
