The Sealed Fort (Japanese: ふういんのトリデ) is a location found in Pokémon Card GB2: Here Comes Team GR!. The fort is sealed until the player has defeated King Biruritchi twice. Within the fort lie nine statues, each of which allows the player to fight a different person. If the battle is won, the player will win a Present Pack.
