Originally, the Aparoid Generator was just a regular generator for Fichina's Climate Control Center. However, after a brief battle between Fox and the Aparoids, Pigma used a Core Memory to transform the generator into an Aparoid. It was set to explode, which would cause the Control Center to melt down and cause environmental damage. Fox quickly destroyed it with Bombs from his Arwing, and saved the planet. These events that unfolded on Fichina taught the Star Fox team that the Aparoid race can assimulate bionic and later organic victims.
Once Fox lands on the surface after wing riding with Falco, Peppy is now able sent Arwing renforcements. Fox will need to shoot down several ejected minor Aparoid units in order to cause the Generator to open it's hatch. The inside core of the hatch is the generator's weakness, therefore the uses of Smart Bomb and Hyper Laser fire are recommended. Yet after opening it's core it will sometimes charge up energy and release a devastating beam.
