About This ROM Hack
Pokémon Sea Temple is an ambitious FireRed-based ROM hack that expands the original structure into a multi-region adventure featuring four interconnected regions, custom systems, and a large-scale legendary conflict storyline.
The hack blends elements from multiple Pokémon generations (Gen 1 to Gen 7) while introducing original concepts such as Ginoan Pokémon forms, Kahuna-based progression, and new ability systems.
At its core, the project aims to create a modern-style Pokémon experience inside a GBA engine, combining traditional gym progression with newer mechanics like Mega Evolution, Z-Moves, and regional variants.
It is a large-scale narrative-driven hack with heavy focus on world-building, legendary mythology, and faction conflict.
Story Overview
Five years ago, an unprecedented battle between legendary Pokémon nearly destroyed the world. In a final act of sacrifice, a mysterious 10-year-old boy sealed himself—along with the Disaster Trio—into an unknown dimension, saving the Pokémon World. His fate remains unknown, but his legend lives on.
The player begins their journey in the quiet town of Criscanto, on the very first day of becoming an official Pokémon Trainer. Under the guidance of the renowned researcher Professor Jimwell Beckett, the player and their childhood friends, Wilhelm and Hazel, receive their first Pokémon from the Kalos region.
Peace is short-lived. A radical organization known as Solar Team emerges, believing Pokémon powers are being abused by trainers. Their goal is to strip Pokémon of their abilities by awakening the Sun God during an upcoming Solar Eclipse.
Meanwhile, an older and more dangerous faction resurfaces—the Lunar Team, led by CLINT, the father of the legendary boy who vanished years ago. Their mission is to gather the Ancient Orbs and awaken Mnemon, the Moon God, triggering a catastrophic Lunar Eclipse.
With both eclipses approaching and rival factions racing toward divine power, the world once again teeters on the edge of destruction. The fate of the regions—and the truth behind the lost legend—rests in your hands.
