Custom Robo

"Custom Robo" is sort of a sci-fi action take on Nintendo's own "Pokémon" titles, featuring a collectible and battle-style gameplay. In the game's story mode, you take on the role of a young boy who has just built his very own toy robot named Ray. Together with your cousin, you head to the Robo Station to take part in a massive Custom Robo battle tournament being held at the local Holosseum. The ultimate goal is to hone your skills so you can defeat Mamoru, the champion among Custom-Robo builders. The gameplay involves customizing robots and fast-paced action battles in tight 3D arenas. A sequel followed.
