The Ghost Masters (Japanese: ゴーストマスターGhost Master) are nine statue-based opponents found in the Sealed Fort, which is located on GR Island in Pokémon Card GB2: Here Comes Team GR!. All Ghost Masters fight a full battle with 6 prize cards. Defeating any of the Ghost Masters gets the player a Present Pack, which can have any of the cards from the game that can normally be found in packs.
The player is first able to access the Sealed Fort after watching the credits for the second time.
