Phantom Brave has a series of extra maps following the main storyline. These post-game maps offer more powerful enemies and feature cameos by some members of the cast of the Disgaea games as enemies. After defeating these characters they will join the player's pool of playable characters as "phantom doubles". While the first couple of extra maps can be completed immediately after the main story, the later extra maps are very difficult and require a large amount of time invested into the game to be spent leveling characters and fusing weapons before they can be completed.
