Sorium is a powerful synthetic crystal invented by the Soviet scientist Anya Turgenova. Sorium crystals contain considerable power and are a source of clean energy but are also highly unstable once removed from their cooling cylinders.

Anya Turgenova developed sorium for the Soviet government at her poorly-scaled laboratory on Stolbovoy Island. Despite the Iron Curtain, news of her discovery reached NASA scientist Doctor Braxis, who identified it as the ideal element to help his Renegade allies conquer of Earth. Battle for GoBotron Zod drew away the garrison protecting the lab, allowing Cy-Kill, Crasher and Cop-Tur to capture Anya and the sorium. Cy-Kill soon demonstrated the power of the element by using a fragment to destroy the laboratory. The Guardians Leader-1, Turbo and Scooter arrived too late to stop them, though they did catch Crasher, who had Anya inside her. However, Leader-1, Turbo, Matt Hunter and A.J. Foster were forced into a cave along with Crasher and Anya by Zod, with Cy-Kill throwing another sorium crystal in after them. The crystal exploded, destroying the mountain. Target Earth Thankfully Leader-1 was able to use his forcefield to contain the blast until Scooter and Nick Burns were able to free their friends with the Command Center. By then Braxis had used the crystals to power his pulsar generator, putting the entire population of Earth under Cy-Kill's control. Conquest of Earth The Guardians were eventually able to free their human friends and foil Braxis' plans, though the Renegades' fleet of Zods were still heading to GoBotron and Cy-Kill had sabotaged the pulsar generator, which would destroy Earth too. Leader-1 then hit on the idea to Astrobeam the unstable sorium into the midst of the Zod armada, saving Earth and GoBotron in one swoop. The Final Conflict

Braxis intercepted a NASA transmission about sorium being transported by truck; however, it was just bait to lure the Renegades into a trap as the truck in question was the Guardian Road Ranger. The Rescue of Road Ranger NASA later located a deposit of sorium in the Amazon, but Professor James Hobby realised it would be impossible to collect due to the presence of Magma Worms. The Rumbling Jungle
- According to the annual story "Meltdown in the Museum", Crasher's arms are made of solid sorium. While this may sound like World Distributors getting confused, it would explain why she's so crazy.
