- Amelia - the mayor of Kattelox Island. She gives MegaMan and the Casketts permission to dig on the island.
- MegaMan Juno - MegaMan Juno, the final boss of the game, is a bureaucrat third class droid from a planet called Elysium. His job is to assume population control of Kattelox Island. When the population reaches a certain amount, Juno re-initializes the population growth by killing the residents on the island through the use of a supercomputer known as Eden and a satellite bombing. He refers to the inhabitants as "carbons" which might mean "carbon based life form". At the bottom of the Main Gate, Juno was in suspended animation until being reawakened by MegaMan Volnutt. Juno then begins making strange revelations, calling him MegaMan Trigger, as well as mentioning to MegaMan that he is a Purifier Model. When Trigger displays signs of not knowing what Juno is talking about, Juno learns that Trigger is suffering from "memory loss" and electrically shocks him in order to "re-initialize" him.
In the far future, much of the world is covered with water and people live on islands. The people here use ancient technology powered by refractors. In order to survive, people called diggers search for refractors and sell them for money and/or to power their flying machines for travel.
Eventually, legends of a treasure called the Mother Lode appeared. It was said that the Mother Lode had many powerful refractors and that, if discovered, it could power the world indefinitely.
MegaMan Volnutt is a digger searching for refractors and the Mother Lode when he, Roll Caskett and Professor Barrell crash on Kattelox Island. There, they must fight the Bonne air pirates and solve the island's many mysteries.
