What is Pokemon Odyssey?

Pokemon Odyssey is a completed GBA ROM hack based on Pokemon FireRed, created by PacoScarso. It offers a fresh take on the Pokemon series. Instead of following the usual path of gym battles and the Pokemon League, this game focuses on exploration, story, and survival in a giant, mysterious labyrinth known as the Yggdrasil Labyrinth, located on Talrega Island. The game is all about exploring dungeons and has a strong story.
Inspired by Made in Abyss and Etrian Odyssey, the game mixes deep storytelling with strategy. Players explore different biomes, face tough challenges, and uncover secrets as they travel deeper into the labyrinth.
Pokemon Odyssey has received strong support from the community for its unique style, exciting gameplay, and fresh ideas. It’s a one-of-a-kind adventure for fans who want something different.
Storyline
On an island in the middle of the ocean, there’s a huge maze called the Yggdrasil Labyrinth. For years, it has drawn in adventurers from all over the world.
No one knows how deep the maze really goes, or what might be waiting at the end. Some believe there’s a treasure beyond imagination hidden inside. Others think the ruins of an ancient civilization are buried there.
In the game, you play as Nyx, a young adventurer who joins a group called the Talrega Guild, hoping to discover the secrets of the Labyrinth.
But things don’t go as planned… something terrible happens.
Key Features
1. A New Region with a New Story
Pokemon Odyssey takes place in a completely new region and follows an original story. You’ll go on a fresh adventure with brand-new characters and a new main hero.
2. Focus on Exploration (No Gyms, No League, No Evil Teams)
This game is all about exploring. It doesn’t follow the usual gym and league system. Instead, the focus is on the story, making the game more fun and exciting in a different way.
3. Pokemon from Generations 1 to 3
You can catch and train Pokemon from Generations 1 to 3. Some older Pokemon can even evolve into new forms from later generations.
4. New Regional Forms
Some Pokemon have special new forms called Etrian Forms. These give the Pokemon a new look, new types, and new stats to match the region.
5. Double Battles Only
All battles in Pokemon Odyssey are double battles—unless you only have one Pokemon left. This means you’ll need to think more about your team and use smart combos to win fights.
6. Every Pokemon is Rebalanced
The game changes the stats and moves of all Pokemon to make them more useful and balanced, so every Pokemon can play an important role.
7. Lots of Sidequests
Besides the main story, there are many sidequests to enjoy. The game even has a special menu to help you track them. These sidequests add to the fun of exploring the world.
8. Brand-New Music
The game features new music tracks that match the new places and events. The fresh soundtrack adds more emotion and excitement to your adventure.
9. EXP Share Like in Gen 6
All your Pokemon get EXP after battles, just like in Gen 6. This helps your team level up faster and cuts down on the need for grinding.
10. Perfect IVs for Every Pokemon
Every Pokemon has perfect IVs (Individual Values), so you don’t need to spend time breeding or farming for good stats.
11. Easier EV Training
Pokemon don’t gain EVs (Effort Values) from normal battles. Instead, you can boost EVs using Power Items or Vitamins, which are now cheaper.
12. Change Nature and Ability In-Game
You can change your Pokemon’s Nature and Ability while playing—no need for breeding or restarting the game.
