Spiritomb
Spiritomb is encountered in the lowest left room in the right corridor, after defeating Groudon or Kyogre. By standing on the top left corner where the player can read an apology about the loss of Odd Keystone, opening a menu so that the player cannot view the overworld and then returning to the overworld screen, an Odd Keystone appears behind the player, and a battle with Spiritomb is initiated.
