Fiction

IDW Generation 1 continuity

Prior to the war, a fire at the Jhiaxian Academy of Advanced Technology was blamed by authorities on a faulty propex conduit. An Intimate Beheading

Superheated propex was used in the ununtrium infusion process that rendered Overlord and other future Phase Sixers virtually indestructible. Remembrance Day

Grimlock was stored in a preservative of a weak propex solution when the Scavengers discovered him. Krok laced it with circuit speeders as part of a plan to fight the Decepticon Justice Division. Who's Afraid of the DJD? The Decepticon pink alchemy facility on Temptoria was protected by a bomb full of propex. Tailgate drained the majority of it in the process of defusing the bomb, but there was still enough left to cause a sizable explosion when the bomb went off, damaging Cyclonus and Rewind.
