Nicktoons: Attack of the Toybots
builds on the idea that all of the Nicktoons exist in the same universe and know each other. Sometime Jimmy Neutron nemesis Dr. Calamitous devises a plan to take over the world by creating armies of robot toys. In order to make sure his plan works, he captures the main heroes - Tak, Spongebob, Jimmy Neutron, Timmy Turner and Danny Phantom - and creates robot duplicates. What he doesn't count on are Cosmo and Wanda, Timmy's fairy godparents, showing up and freeing one of the heroes. However, they only have enough power to free one, who then sets out to free the others by defeating the robots that hold the cell keys.
Attack of the Toybots is a pure platformer, though with a slight free-roaming twist. Levels are huge and feature numerous paths to the end. The catch is that each path is meant for a specific Nicktoon. Danny can phase through certain walls, while Tak can climb up vines. It makes for interesting gameplay, though it really doesn't matter much in the end. There's nothing particularly interesting between the alternate paths other than maybe stumbling across a random Nicktoon character standing in the background. Level design is pretty basic and doesn't stray too far from what players have seen in other games. This presents a real problem for the game since it becomes incredibly repetitive after the first two levels - especially once you start rescuing characters, since you'll have to lead each through the level.
Each level ends in a battle with one of the robot duplicates. Battles are really basic and usually just turn into shoot-outs. You usually have a tank during each battle, though the damage output doesn't seem to make up for the lack of mobility, especially after unlocking attack upgrades.
