About the Game

Pokémon Battle Theater is a Pokémon Emerald game focused on battle simulation rather than a traditional Pokémon adventure. The project uses the pokeemerald-expansion engine and lets you select trainers from across the main Pokémon games. You can watch two teams fight under AI control or take control of one side through Pilot Mode.

The project currently documents around 120 curated trainer rosters from different generations. The roster includes characters from Kanto through Paldea, Hisui, Pokémon Colosseum, Pokémon XD, and other Pokémon content.

🧑‍🏫 Trainers From Many Pokémon Eras

The roster is one of the strongest parts of the project. You can find teams associated with characters such as:

Red
Blue
Silver
Cynthia
Steven
Wally
Lance
Ash
Paul
Volo
Nemona
Legends: Arceus characters
Pokémon Colosseum characters
Pokémon XD characters
Battle Frontier trainers
Pokémon World Tournament trainers

The project also recreates the teams from the 2012 VGC World Finals for Wolfe Glick and Ray Rizzo. The documentation specifically notes their famous Trick Room versus Tailwind matchup.

You can therefore create matchups that would never occur in the original Pokémon games.

🎮 Pilot Mode Gives You Control

AI battles are not your only option. Pilot Mode lets you control one side yourself with a selected trainer's team. You do not need to catch or train the Pokémon first. The mode provides:

A preset trainer's team
Direct control during battle
No normal grinding requirement
Automatic badge support for obedience
Suppressed experience gain
Access to preset and custom teams

🏆 Tournament Mode Gives You a Bracket

Tournament Mode uses an 8-trainer single-elimination bracket. You can select:

Singles
Doubles
VGC
Best of 1
Best of 3
Random Spectate
A trainer to follow
A trainer to pilot

Best-of-3 tournaments can use adaptive team selection between games. The project also supports different tournament cups with region-specific trainer pools. This setup gives your battles a clear competitive structure.

🧠 VGC Mode Uses Specific Rules

VGC Mode is not simply a normal Doubles battle. The documented format uses:

Doubles
Level 50
Bring 6, pick 4

The project also includes AI support for team-preview decisions.

That makes VGC Mode useful if you want battles that follow a more competitive tournament structure.

🛠️ Build Your Own Teams

Battle Theater contains an in-ROM custom trainer editor. For each Pokémon, you can configure details such as:

Species
Nickname
Sprite
Held item
Ability
EVs
IVs
Four moves
Nature
Gender
Shiny status

📋 Pokémon Showdown Teams Can Enter the ROM

One particularly unusual feature is the Showdown team-code system. You can build a team in Pokémon Showdown, use the project's offline encoder, and enter the resulting short codes into the ROM. The system can transfer information such as:

Species
Held item
Ability
Moves
EVs
IVs
Nature
Gender
Shiny status
Trainer information

The encoder works offline through an HTML file. The project documentation states that it does not require an internet connection, link cable, or additional ROM patching for the import process. This is a strong feature for anyone who already builds competitive teams on Showdown.

🏟️ Battle Frontier Challenge

Battle Theater also gives the Battle Frontier a larger role. You can borrow a preset trainer's team and use it in Frontier facilities such as:

Battle Tower
Battle Dome
Battle Palace
Battle Arena
Battle Factory
Battle Pike
Battle Pyramid

👻 Shadow Pokémon Connect the Game to Orre

The project also incorporates material from Pokémon Colosseum and Pokémon XD: Gale of Darkness.

The Orre content includes Shadow moves and trainers from the two games. The documented roster contains characters such as:

Miror B.
Dakim
Venus
Ein
Nascour
Lovrina
Snattle
Gonzap
Greevil
Ardos
Eldes

The Shadow move system follows the special mechanics associated with the Orre games.

This gives Battle Theater a connection to a part of Pokémon history that rarely appears in Game Boy Advance games.

🐉 Shadow Lugia Gets Custom Treatment

The latest boss update gives XD001 its own Shadow Lugia presentation. The documented implementation includes:

Purple body
Silver armor plates
Red eyes
Front battle animation
Back sprite
Party icon
Four Shadow moves
XD001 name
A custom Pokédex entry

Regular Lugia remains separate from XD001.

🎯 Some Trainers Use Pokémon Pools

Not every trainer has to use exactly the same six Pokémon every time. The project contains trainers with larger Pokémon pools. The AI can select a team from those pools for a particular battle.

The documentation gives examples such as Ash, Paul, Gary, and Battle Tree trainers.

This can make repeated battles against certain trainers less predictable.
