Play Gekitou Power Modeller (Japan) Online

Gekitou Power Modeller was a Japan only Game Boy release from 1996, developed by KID and published by Imagineer. It arrived in the later years of the handheld, a time when developers were experimenting with more niche concepts beyond straightforward platformers and RPGs.

You play as a hobbyist building and battling small, customizable robots. The core loop involves purchasing parts like motors, wheels, and armor in a shop, then assembling them in a grid based garage interface where weight distribution and part compatibility are crucial. The main objective is to defeat opponent models in one on one arena fights; victory earns prize money to buy better components. The pacing is deliberate, focused on thoughtful construction rather than frantic action, and a poorly balanced robot will tip over or perform poorly. It feels like solving a physical puzzle with the reward of seeing your clunky machine come to life.
