Beyond the gyms and the League, Modern Emerald has a set of one-off bosses: Wally's story battles, Maxie and Archie at the hideouts, and Matt as the Aqua admin you fight on the way through. They have all been rebuilt to the same standard as the gym leaders — new teams, new movesets, and hold items.

The big ones

TrainerWhereWhat to bring
Wally
Mauville Gym, then Victory Road
Electric or Ice for Altaria; something fast for his Gardevoir
Maxie
Magma Hideout
Water and Ground — his Camerupt and Mightyena fold to them
Archie
Aqua Hideout
Electric and Grass; watch for his Sharpedo's Speed
Matt
Aqua Hideout
Anything physical; his team is bulky rather than fast
Steven
Postgame rematch
Level 85–88, Metagross at 88 — the hardest fight in the game

They all show up again in the Battle Frontier

Gym leaders, the Elite Four, both champions, Wally, the Magma and Aqua leaders, Red and Leaf all appear as opponents during Battle Frontier challenges. Every facility caps your team at level 50, so those fights are about team construction rather than levels.

Team and rematch structure from the extracted game data and the official Modern Emerald documentation. The extracted special_trainers.json currently publishes Steven's team in full; the other bosses' teams are in the trainer database.
