War Against Fuse
During the Planetoid Fusion crisis, Courage (with the help of the Hero) is ultimately the one that destroys the planetoid by reversing the polarities of a UFO magnet found in Nowhere which was pulling the planetoid to Earth. With the polarities reversed, the Planetoid Fusion was crushed by its own force and was successfully destroyed before it reached Earth.
Courage acts as a mission handler for players following Edd as a guide. He helps the player track down the Crazy Brain Candy. The player ends up with two dead ends before discovering Fuse had taken the candy to his lair. Courage also helps the player to save the Magic Tree from becoming infected by the Dark Tree. Courage gives out Candy Pirate and SACT gear that he found in Nowhere.
Status of the Bagge Family
It is hinted that at least Muriel is hiding in the farmhouse, as Courage had the player retrieve her slippers from monsters as a Guide Mission from Edd ("Slippery Foes"). Kevin states that Muriel is letting him stay until he can get his car fixed.
The mask Eustace uses to scare Courage is a possible drop from fighting fusion monsters. There was also a shirt based on him, which was originally the Top Dog Tee. At Goat's Junk Yard, there is a billboard that advertises Nowhere with Courage on it.
