From Golden Sun Universe
So far, Crossbone Isle has appeared in the following games:
- Crossbone Isle (Golden Sun) has been around since the the original Golden Sun game. The final boss is Deadbeard, who held the title of "strongest boss" in that game.
- Crossbone Isle (Dark Dawn) returns in Dark Dawn. Deadbeard has been replaced by Dullahan, and among the treasures the island holds are the Charon and Iris summons. In Dark Dawn, Crossbone Isle cannot be accessed until players have defeated the game's final boss, or unless they use the Endless Wall glitch.
- The World Map portion of Crossbone Isle is coded into Golden Sun: The Lost Age. However, it is located in an ocean to the west of Mars Lighthouse that is only reachable through the use of a glitch. There are no loading zones leading to the dungeon itself. 
- In the original Golden Sun, the above island is instead located to the west of Imil, instead of its story location of the Karagol Sea.
