A bosses of Star Fox 2, Mirage Dragon is the boss of Lylat and Space Blade is the boss of Eladard. Hunter Tektron replaces the Attack Carrier as the boss of Corneria in Medium Route. Hunter Phantron replaces the Rock Crusher as the boss of Sector X. As a result, the Attack Carrier and the Rock Crusher only appear once in Easy Route.

The objective of Star Fox 2 is to destroy all enemy forces present in the map while defending planet Corneria (located in the lower left corner of the map), preventing its health level from reaching 0%.
