Onibi Island is a location in Rockman.EXE Beast and Beast+. It is an uninhabited island that was once used as a weapons factory during a war. When Netto Hikari, Meiru Sakurai, Meijin, and Rin Manabe were called it to investigate a “ghost ship” that Higure and Shuko Kido discover, Meijin notices that strange electromagnetic waves were flowing into the island, reactivating it while causing power outages in the nearby town and lighthouse. Netto and Meiru plug Rockman.EXE and Roll.EXE into the lighthouse in an attempt to stop the flow (with Trill.EXE tagging along by latching onto Rockman’s leg), but are attacked by viruses and Zoano FlameMan.EXE.
A general of Glaga, FlameMan had discovered that Falzer’s army had created a Copyroid factory on Onibi Island, and with the Onibi warship, destroys the entire island and Falzer’s Copyroid factory with it, though many of the Copyroids survived, and are claimed by Glaga’s army.
