The Plax were a race of merciless and aggressive alien androids that Sonic first encountered in the Shanazar desert, stopping them from using a mining machine called 'The Rig' to generate powerful earthquakes that destroyed several surrounding communities.


Characteristics and culture

The Plax were a collective race, sharing the same mind. This is attributed to be the cause of their telepathic abilities.

Powers and abilities

The Plax claimed to be a form of living plastic known as Plastic-X that could be molded into any shape and could not be harmed by any conventional means.


After Shanazar and Mobius were merged, the Plax swore fealty to Doctor Robotnik, believing him to be the spiritual leader that their prophecies had foretold. With his help, they designed a machine that allowed Robotnik to drain the life-force of Mobius, making him almost omnipotent. They fought Sonic and his team to a standstill to defend Dr. Robotnik until the process was complete, but were convinced by Robotnik's lackey Grimer that the villain planned to betray them as well. The Plax attempted to stop Robotnik, but were easily destroyed by the powerful mad scientist.
