Great Yggdrasil rises over Lemuria.
01 / Welcome to Lemuria
A race toward the World Tree
Every ten years, Lemuria’s monarch declares the Great Lemurian Race. Adventurers and their Pokémon face trials, treasure hunts, and fearsome foes for the chance to meet the Overlord in a floating fortress above Yggdrasil.
This is a direct sequel to Pokémon Odyssey, again combining Pokémon with Etrian Odyssey-inspired exploration. The first adventure is recommended for story context, though the demo can be played on its own.
02 / What makes the sequel different
A new expedition. Different rules.
The demo moves away from the traditional Gym formula and focuses on story, exploration, and teams built for Double Battles.
01Battle system
Double Battles lead
Battles use the doubles format unless you only have one Pokémon. Team synergy shapes each encounter.
02Build your explorer
Eight subclasses
Choose one of eight documented subclasses, each with its own perk and starting items.
03A new regional dex
300+ Etrian Variants
More than 300 species from Generations 1–9 are reimagined as regional variants, alongside the Aether type.
04Expedition systems
Explore beyond battles
Mining and Gathering points, F.O.E.s, sidequests, and a dedicated quest menu reward exploration.
05Choose the challenge
Difficulty and level caps
Multiple difficulty settings and optional soft level caps let you tune the journey.
06Build without the grind
Team tools
Perfect 31 IVs, nature and ability changing, easier EV management, and DexNav keep the focus on team building.
03 / Battle as a team
Two partners take the field.
Odyssey II centers combat on Double Battles. Only a trainer with a single Pokémon fights alone, making team pairings and complementary roles part of the core journey.
Documented ruleDouble Battles only, unless you have one Pokémon.
Battle information is available through the in-game Dex interface.
04 / Choose your subclass
Eight perks for the road ahead.
The selection screen documents one perk and a starting item set for each subclass. Your choice changes how you approach exploration, resources, or early battles.
