A grand adventure set in the diverse Muzon Region! At the heart of the conflict lies the sinister Team Umbra, an ancient organization obsessed with achieving immortality. Their failed attempts to harness the power of the legendary Ho-Oh resulted in the creation of Corrupted Forms-feral Pokémon mutated by experimental exposure to chemicals found in the region's Flabébé population. Team Seraphs is a resistance group fighting to protect Muzon's ecosystems and its people, aiming to stop the spread of these dangerous mutations. You'll take on the role of either Carter or Grace, twin siblings from the wealthy Salone family who receive rare Pokémon from Professor Agerwood and begin a journey across the region's eight gyms. Along the way, you'll face rivals like Micah, meet allies such as the former Hoenn Champion Raisen, and unravel the truth behind Team Umbra's century-long legacy.
