The Lost Hex is a floating landmass from the Sonic the Hedgehog series that is home to the Deadly Six.


Worlds Unite

Dr. Eggman took over the Lost Hex and established a base there by subjugating the Deadly Six. Sigma monitored his activities from his own world and subsequently traveled to the Lost Hex through a Genesis Portal. Taking possession of Orbot, he destroyed Eggman's means of controlling the Zeti and forced him to create a new body for him. After bringing Dr. Wily there as well, he forced the pair to convert Eggman's facilities to his use, such as remaking his robot assembly line to construct Mechaniloids.
