Adventurous Spirit of Steel

 * Mega Man Volnutt exits a ruin after finding the refractor inside. After dealing with the Reaverbots blocking his way out, he makes his way to the Flutter, which leaves the ruin.
 * However, the Flutter experiences some engine problems and crash lands on Kattelox Island. From there, the Casketts try to find a way to repair their ship. However, when the pirates the Bonnes attack Kattelox's city with giant mechanical weapons, Mega Man decides to stop them.
 * Once Mega Man defeats the Bonnes, Kattelox's mayor, Amelia, tells Mega Man the Bonnes are searching for the island's secret treasure and that it is said if somebody obtains it, a great disaster will befall the island.
 * Amelia asks Mega Man to investigate the island's ruins. With a refractor found in a ruin, Roll and Mega Man repair the Flutter, allowing them to find a cave to continue exploring the island.
 * While exploring the cave, Mega Man activates the Main Gate, a dungeon where he should be able to find the reason why Reaverbots from the island are being activated.
 * Mega Man confronts the Bonnes who, after being defeated once again, decide to let Mega Man enter the Main Gate, planning to steal the treasure from him afterward.
 * When Mega Man explores the depths of the Main Gate, he discovers it is actually a stasis chamber for the ancient robot Mega Man Juno, a 3rd class bureaucratic unit from Eden, a space station orbiting above the planet. When he is accidentally awakened from his sleep by Mega Man, Juno refers to Mega Man as "Mega Man Trigger", and realizes that Mega Man is suffering from memory loss.
 * Juno claims that the island's population needs to be purged so it will be more controllable, and confronts Mega Man when he tries to stop him. After a struggle, Juno is defeated and dies.
 * Even with Juno's physical body gone, he transfers his backup data into the systems of Eden, preventing the halt of the Carbon Purification Process.
 * Data gives new commands to the system, stopping the Purification and deleting Juno's backup data from Eden.
 * Data then reveals to Mega Man that he contains all of his previous memories from when he was Mega Man Trigger.
 * Mega Man had stored his memories into Data as a way to prevent Eden from ever tampering with it.
 * Data promises to restore Mega Man's memory when the time comes.
 * The residents proclaim Mega Man a hero and the Caskett family rides off in the repaired Flutter to continue their journey.
 * The Bonnes sail on a vessel built by Tron out of the scraps from the Gesellschaft, with the giant refractor from the main gate and Bon Bonne in tow.
