"Say your prayers, toitles"
— Rocksteady

As an important, recurring villain in the 1987 cartoon, Rocksteady naturally found his way into the video games based on it, usually as a boss character.

Teenage Mutant Ninja Turtles (1989 video game)

Rocksteady appears first, guarding a captive April while the player fights Bebop in the sewer of level 1. He later appears, in a warehouse at the end of the level, as the player attempts to rescue April. He fights with a shoulder charge, and his machine gun. Notably, in some versions of the game, he is very easily defeated by crouching Donatello on top of the stake of crates at the edge, and repeatedly swinging his downward.

Teenage Mutant Ninja Turtles (arcade game)

Rocksteady serves as the first boss of the arcade game, coming out of a Module that has somehow breached April's apartment. He fights with his machine gun and shoulder charge, and will also kick away any Turtle that gets too close to him. In the arcade game, he later reappears in a dual-boss fight with Bebop. In most home versions, this fight is replaced with Baxter Stockman in his fly form.

Teenage Mutant Ninja Turtles: Fall of the Foot Clan

Rocksteady once again was the first boss. He wielded a standard single shot rifle, and his ammunition could be deflected with a well-timed weapon strike.

Teenage Mutant Ninja Turtles II: Back from the Sewers

Rocksteady's fight is very much like his previous incarnation, including being the first boss again, and having deflectable bullets. However, he had his machine gun again, and has a jump attack. A Foot Soldier also drops items from a window in an attempt to damage the player.

Teenage Mutant Ninja Turtles III: The Manhattan Project

Rocksteady appears as the first boss of this game, leaping from the water at the end of the boardwalk. He is very much like his Arcade Game version, but carries a spear gun.

Teenage Mutant Ninja Turtles: Manhattan Missions

Rocksteady is the boss of Extortion Mission 3, using his machine gun once again.

Teenage Mutant Ninja Turtles: Turtles in Time

Rocksteady only appears in the Super NES version, dressed in pirate garb and wielding a fencing foil. Bebop accompanies him for a dual boss. The two are capable of getting their weapons stuck together, letting players hit them for free.

Teenage Mutant Ninja Turtles: The Hyperstone Heist

Rocksteady appears as the second boss, and this is the only time he appears in a game that Bebop does not also appear. He fights much like his Arcade Game version, only he is also capable of tossing grenades. An orange recolor version appears during The Gauntlet stage.

Teenage Mutant Ninja Turtles: Tournament Fighters

Rocksteady's final video game appearance was as an observer of fights in the Mt. Olympus stage. He is inexplicably green here.

Rocksteady is playable as Rocksteady (Classic) and Rocksteady (Bunny)
