The Metarex Deserd was encountered by the crew of the Blue Typhoon on the plant of the Hobidon where it made itself appear as a maze-like mansion. After toying with Sonic the Hedgehog, Amy Rose, and Knuckles the Echidna within the walls of this mansion, it turned into a mass of nanites and began attacking. Though the Metarex Deserd proved too powerful for the heroes, it was eventually defeated upon the unexpected appearance of Shadow the Hedgehog, who used the power of a Chaos Emerald to boost his own abilities and destroy Deserd's core.
Powers and abilities
The Meratex Deserd was composed of nanites, making it capable of taking on multiple forms. Its makeup made it virtually impossible to damage, as it could form super-strong walls and break them apart without damage. It could also create organic-looking structures such as a fang-filled mouth or eyes. Additionally, it was capable of harnessing destructive energy.
