Styx

One of the best Decepticon prisons in the galaxy and it gets beaten by a computer program.

A small ice and snow-covered moon orbiting Charon, a vast gas giant, is home to the Decepticon penal colony called Styx. Of all such installations it is the harshest and most brutal. Prisoners sent to Styx have a short life-expectancy and may be better off for that. The penal colony is said to be impregnable.

Gutcruncher was stationed there for a time, before he was on Banzaitron's team.

Fiction

IDW Generation 1 continuity

At some point during the war, all Decepticons imprisoned at Styx were re-engineered into living bombs and forced to join the K-Class. Among these individuals was Fulcrum, who was awaiting execution by Traitor's wheel for running from a battle. Who's Afraid of the DJD?

Hot Rod impregnated the impregnable prison (get your mind out of the gutter) with a virus that let him sneak in and free his former comrade, Dealer. Although Dealer seemed appreciative, he failed to give Hot Rod a "Domo arigato". Spotlight: Hot Rod

The Decepticon battalion commander Gorelock was imprisoned there for giving aid to Overlord. Gorelock's prisoner clemency request
