That's exactly the wild crossover premise behind Sonicmon Fire Red — a GBA ROM hack by The Pech that replaces the Pokémon roster with iconic characters and creatures from the Sonic universe, dropping them into the familiar structure of Kanto for a uniquely bizarre and endlessly entertaining adventure. Explore the classic Kanto region, battle Gym Leaders, and build your team — except instead of Custom cartridge, plug and play. Compatible: GBA, GBA SP, DS, DS Lite.
