Teenage Mutant Ninja Turtles: Dimension X Assault

Teenage Mutant Ninja Turtles: Dimension X Assault is a stand-alone handheld video game by Tiger Electronics, released in 1995. It is the only video game to take characters and designs from the infamous "Red Sky" episodes of the 1987 Teenage Mutant Ninja Turtles series.

The game's chief villain is Berserko, who has a plan to destroy the Earth as revenge on the Ninja Turtles. He utilizes "Gamma Bombs", which must be deactivated at the end of every level (save for the final stage), and finally appears in his "Annihilater" (sic) vehicle as the final boss.

Other than Berserko, the enemies include Foot Soldiers, Bebop, and Rocksteady.

The game's instruction manual is known for taking liberties with the series' canon (relegating all of the general foes to being servants of Berserko), character identification mistakes (swapping Donatello and Michelangelo's portraits, referring to the Foot Soldiers only as "Cyber-Soldiers"), massive amounts of typographical errors, and overuse of outdated slang on an embarrassing level even for its period of release.
