Combination Robot

Custom Robo is an action RPG for Nintendo 64 where players command tiny customizable robots called Custom Robos in holographic arenas. Players assemble and upgrade their robo by swapping chassis, guns, bombs, pods, and boots, each with unique abilities affecting speed and power. Battles are frantic one-on-one fights with auto-aiming and a short knockdown mechanic. The story follows a young boy who receives his first robo named Ray from his mom on his birthday and competes in tournaments to become a top commander, uncovering a shadowy organization using nano-robot tech. Key characters include Ray (the starting robo) and supporting figures in the town. What makes it stand out is its deep robo customization system for strategic battles in confined 3D arenas with fast, nimble movement.
