Oroku Saki (1987 video games)

The Shredder appeared in many of the video games based on the Teenage Mutant Ninja Turtles (1987 TV series), usually, but not always, as the final boss.

1989 home console 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 Retromutagen Ray, 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 is used to turn Splinter back into Hamato Yoshi.

Teenage Mutant Ninja Turtles: The Arcade Game
The Shredder first appears at the end of the first level after the players defeat Rocksteady, kidnapping April 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 a device that de-mutates the Turtles, killing them instantly. He is also able to create clones of himself, the exact number of which reflecting on how many players are currently playing the game. When Shredder or one of his clones nears defeat, his helmet falls off.
