Xevious

The planet Xevious is a primarily mechanized planet inhabited by the imperialistic Xevian race, consisting of countless metal structures and a red sky. This is the fourth planet of seven discovered as capable of supporting life, and the one ultimatly chosen by GAMP, who fused his central core with that of the entire planet upon arrival. From Xevious, GAMP oversees the operation of reclaiming the planet Earth, carried out by his own forces and fleet, during the "Dimension" saga. However, Xevious itself eventually falls under attack after the events taking place at the Nazca Lines, when the alliance of heroes becomes aware of GAMP's presence there—along with the rest of the Xevians.

Sonic the Hedgehog, Zim, and Operation Solvalou each arrive to at last defeat their enemies, the resulting dogfight taking place in the red sky while GAMP and his ex-commander Tak are battled by Sonic and Zim, respectively, atop the large metal structures. As GAMP's central core is ultimately destroyed by Sonic, not only does GAMP explode, but everything on Xevious begins crumbling as well, all of the metal structures deteriorating and the planet itself becoming unstable without a central core. The planet Xevious becomes engulfed in a massive explosion, as Sonic, Zim, and the Solvalou ship make their escape from the destroyed planet.
