Pokemon Gaia is one of the most polished and widely respected Pokémon ROM hacks ever created. Built on Pokémon FireRed, it introduces the entirely new Orbtus region, a deep original story, ancient ruins, and modern Pokémon mechanics.
Pokemon Gaia is a feature-complete FireRed ROM hack developed by Spherical Ice. It is set in the Orbtus region, a land rich in history, mysterious ruins, and powerful legendary Pokémon tied to ancient civilizations.
The story follows your journey as a young trainer who becomes entangled in the ambitions of Team Epoch, an organization obsessed with awakening ancient powers buried within Orbtus’ ruins. As you travel across deserts, jungles, islands, mountains, and underground temples, you uncover secrets that reshape the region’s fate.
Gaia is famous for its dungeon design. Many areas feature multi-layered ruins, environmental puzzles, hidden chambers, strength and light-based mechanics, and classic adventure-game elements rarely seen in Pokémon hacks.
Gameplay is modernised with features inspired by later generations, including updated moves, abilities, improved move tutors, expanded Pokémon availability, physical/special split, and numerous quality-of-life upgrades.
Beyond the Elite Four, Pokemon Gaia continues with a large postgame that expands the world, introduces new legendary encounters, optional dungeons, and high-level challenges.
