Teenage Mutant Ninja Turtles (1989 home game)
The Shredder appears as the final boss at the end of the Technodrome level. He wears a red costume similar to his Mirage Comics counterpart and fights using the Life Transformer Gun, which de-mutates and instantly kills the Turtle that the player controls. He also takes away roughly half of the player's health if he is touched. After he is defeated, the Shredder turns into a pile of ash and the Retromutagen Ray Generator is used to turn Splinter back into Hamato Yoshi.
Teenage Mutant Ninja Turtles (1989 arcade game)
The Shredder first appears at the end of the first level after the players defeat Rocksteady, kidnapping April O'Neil and escaping. The third level features Shredder appearing on several monitors while exclaiming "Tonight I dine on turtle soup". He also appeared in the preceding cutscene guarding the captive April with Bebop and Rocksteady (Baxter Stockman in the NES port).
Ultimately, Shredder appears at the end of the game in the Technodrome level as the final boss, faced immediately after Krang. He attacks with a sword and lightning bolts from a device on his helmet, that de-mutates the Turtles, killing them instantly. He is also able to create clones of himself (the exact number of clones is one more than the number of Turtles attacking him in the arcade version). When Shredder or one of his clones nears defeat, his helmet falls off, a unique occurrence in the game series..
This game was the first one not to feature Shredder as the final boss. Instead, Shredder appears as the next-to-last boss in the river level, armed with a sword and able to teleport when hit. It is also the first game in which Shredder doesn't have the ability to de-mutate the Turtles. Krang is the final boss.
In this game for the DOS computer system, Shredder is the final boss in his Manhattan hideout, decorated in a Japanese style. He also appears in the ending being turned over to the police by the Turtles. His appearance is based on the Mirage comic version.
This game is the first to feature both a battle against Shredder and a second one against a mutated Super Shredder. Shredder first appears as the boss of level six, the Technodrome level, attacking with a sword. He later returns as the final boss on the stage set in Krang's spacecraft and assumes the form of Super Shredder much as he did in the second movie which had been released earlier the same year (1991). As Super Shredder, the Shredder can summon lightning and shoot fireballs that temporarily de-mutate the Turtles, taking some of their energy.
A sequel to Fall of the Foot Clan, this game also features Shredder as a regular level boss and Krang as the final boss. He does not have the ability to de-mutate the Turtles, but he does have a wider variety of attacks than in the previous Game Boy game. Shredder first appears as a regular stage boss, attacking the Turtles by punching, kicking, and running from side to side. He later returns as the penultimate boss of the final Technodrome level in the mutated form of Super Shredder. However, in this incarnation, his only super-power is the ability to teleport elsewhere on the screen. Super Shredder attacks with a sword and occasionally teleports and kicks the Turtles. Krang is once again the final boss.
In the arcade version, Shredder is again the final boss of the game found in the Technodrome level and attacks with a sword, fire hand shots and eye beams. However, this time, he is not preceded by a Technodrome level. Instead, the Turtles fight through a Starbase level in the future (2100 AD) with Krang as boss, then teleport to the Technodrome in the present (1991 in the arcade game and 1992 in the SNES version) for the final confrontation. In the SNES version, an earlier Technodrome level was added that featured a regular Shredder. In this battle, Shredder is in a kind of battle tank armed with a machine gun and claws as the main stage boss, being defeated by throwing the never-ending waves of Foot Soldiers toward the screen at him. The player views the action over Shredder's shoulder inside the tank. In the same version, the final boss has Shredder become Super Shredder and has the added superpowers of super-speed movement, and attacks with three different attacks: Red that create a trail of flame in front of him, blue that fires upward and freezes the Turtles, and green fireballs that de-mutate the Turtles costing them a life.
In the Re-Shelled remake, Shredder is once more the final boss and uses a sword, fireballs and eye beams.
This Sega Genesis game featured a Super Shredder similar to the one in the SNES version of Turtles in Time as the final boss. His attacks are roughly the same with the exception of his blue attack not freeing the Turtles.
Unlike the previous Game Boy games, Fall of the Foot Clan and Back from the Sewers, Shredder is the final boss. He attacks by kicking and throwing fireballs. After he is defeated once, his health bar instantly refills and he fights again, this time with more vicious attacks. He is the only boss in the game with two life meters, He is called Cyber Shredder, half-man and half-machine in the game's credits and box.
This is the first game in which Shredder is not a boss but instead a regular playable character. Furthermore, his costume is based on the Mirage comics version. Shredder is a fully playable character in the NES and SNES versions of the game. He is called Cyber-Shredder in the SNES game, but there is no indication that he has become a cybernetic being as in Radical Rescue..
