Teenage Mutant Ninja Turtles 2: Battle Nexus was released for the Game Boy Advance; which is 2D platformer, opposed to it's concurrently released variation for PS2, GameCube and Xbox that is a third person beat 'em up. It released in 2004 by Konami and was the sequel to Teenage Mutant Ninja Turtles and based on the 2003 TV series.
The game begins with a battle with the Foot Clan and Hun in Oroku Saki's skyscraper. The Foot is defeated, and Master Splinter mysteriously disappears. The Turtles chase the trail down to a building marked "T.C.R.I.", which proves to hide a bizarre secret beneath its innocuous exterior: its employees are members of a brain-like alien race, the Utroms. Whilst battling these strange new foes, the Turtles are accidentally teleported to different points across the galaxy, meeting the Fugitoid Professor Honeycutt on D'Hoonib, and end up as crossfire in the war between the Triceratons and Federation - both sides are after the Fugitoid for his technology. Along the way, they come across an intergalactic bounty hunter named Slashuur. Said to be the most powerful bounty hunter in the universe, Honeycutt heard legends of him as a young child. Ironically, Honeycutt is who Slashuur is after, having been hired by the Triceratons to capture him. After the Turtles beat him, Slashuur reveals that he has knowledge of Hamato Yoshi before taking his leave. Before escaping the Triceraton Homeworld, the Turtles befriend and free a noble Triceraton warrior who had been forced to fight as a gladiator, Traximus. Upon returning to Earth and the T.C.R.I. building, it is revealed that the Utroms had rescued an injured Splinter and were caring for him. The Utroms place the TMNT and Splinter in a virtual reality machine to better explain their origins to them. Hundreds of years ago, the Utroms were traveling across the galaxy, transporting a murderous rogue of their species, Ch'rell. Their ship crashes on Earth in the country of Japan. Ch'rell escapes, while the Utroms are forced to wait for Earth technology to catch up with their own, so they can return home. Some time later, after the Utroms have enlisted the help of some humans as Guardian Ninja, the Utroms are ambushed by a heavily armored warlord known as The Shredder. Meanwhile, in the real world, Baxter Stockman sabotages the virtual reality machine, and the dangers within become presented as real to the Turtles and Splinter. After defeating Shredder and his Feudal Foot Ninja, the Turtle meet up with the Utrom Mortu, who gives them a device that allows them to return to the real world. Unfortunately, when they get there, they find Shredder and the Foot attacking the T.C.R.I. building. During their fight, an organic destruction device is planted, and the Utrom escape through their Transmat. The Turtles defeat Shredder before he can chase after them, and it is revealed that not only is this Shredder the same one they saw in Feudal Japan, but he also is the evil Utrom Ch'rell! The Turtles escape the building before the device goes off, but Ch'rell is not so lucky.

The storyline of E.V.O.: Search for Eden follows the same patterns as modern Evolution theories. The players first controls a prehistoric sea organism, and fights to gain evolution points with which he can improve his fish's body parts and upgrade his attack/defense abilities. The gameplay is not completely linear, which means that certain choices of paths and stages will affect the player's success. The game is composed of a series of stages, in which the sea organism slowly evolves into an amphibian, and later a land-only creature. The physical changes are fairly scientifically accurate which gives the game a semi-educational purpose as well.

Because of a rise of anti-mutant activity in Genosha, Professor Xavier uses Cerebro to scan the island nation and discovers Apocalypse's presence there. Genosha's government is apparently using Apocalypse to bring their mutant population under control. However, Xavier suspects Apocalypse to follow his own plans and sends five X-Men, Cyclops, Wolverine, Psylocke, Beast and Gambit, to investigate. X-Men: Mutant Apocalypse combines the gameplay of a side-scrolling brawler like Final Fight with elements of a platformer, that is, players have to fight various enemies and survive the occasional jumping-puzzle. Most levels also feature mid- and end-bosses in form of robots, monsters or known Super-Villains. Each character has unique abilities and special moves: Cyclops uses his Optic Blast to attack enemies from a distance, Wolverine can climb walls, Psylocke is very agile and the best jumper of the team, Beast can cling to the ceiling while Gambit throws explosive cards at his enemies. Special moves are quite similar to those found in Street Fighter II (Wolverine has a Dragon-Punch-style attack and Gambit's Double Kick is virtually identical to M. Bison's Scissors Kick), and require similar button combinations. While most stages are unique for each character, some can be played with any of the X-Men. Progress is saved via password.
