Nicktoons Red and Blue are films that began in 1996. This is somewhat similar to the Pokémon games.
The silent protagonist of Red and Blue is a young preteen who lives in Nick Town. After venturing alone into deep grass, a voice warns the player to stop. Professor Stu Pickles, a famous Nicktoons researcher, explains to the player that wild Nicktoons may be living there, and encountering them alone can be very dangerous. He takes the player to his laboratory where the player meets Stu's grandson, a rival aspiring Nicktoons Trainer. The player and the rival are both instructed to select a starter Nicktoon for their travels out of Doug, Stimpy, and Susie Carmichael. Stu's Grandson will always choose the Nicktoon which is strongest against the player's starting Nicktoon. He will then challenge the player to a Nicktoons battle with their newly obtained Nicktoons, and will continue to battle the player at certain points throughout the film. While visiting the region's cities, the player will encounter special establishments called Gyms. Inside these buildings are Gym Leaders, each of whom the player must defeat in a Nicktoons battle to obtain a total of eight Gym Badges. Once the badges are acquired, the player is given permission to enter the League, which consists of the best Nicktoons trainers in the region. There the player will battle the Elite Four and finally the Champion: the player's rival. Also throughout the fillm, the player will have to battle against the forces of the Rugrats (Tommy, Chuckie, Phil, and Lil), who behave similar to Team Rocket, a criminal organization that abuses Nicktoons.
