Immorticon is a Decepticon Transcendent Technomorph from the TransTech continuity.

Immorticon's stolen body being blasted apart by Megatron.

Little is known about the Transcendent Technomorph named Immorticon. What is known is that he was a member of the elite class of the city Axiom Nexus on a peaceful Cybertron where no Transformer civil war had broken out. However, he was kidnapped by the vile offworlder Alpha Trion and ousted from his chassis in favor of a lowtech counterpart loyal to Trion's cause.^[1]

Fiction

TransTech

As Alpha Trion had not given Topspin any specific orders on what to do with the TransTechs' sparks, Topspin, unable to bring himself to destroy the sparks, hid them away in storage. Eventually, Immorticon's spark, along with those of Blackarachnia and Nightscream, was rescued when an OZSA team led by General Optimus Prime raided Alpha Trion's old laboratory, which had more recently been used by publicly-known terrorist Cy-Kill.

Notes

Alas, his innate minty-ness was not to be.

• Immorticon was originally a new character designed for the Transtech series, transforming into a tank-thing. Like most toys being developed for the line, he never got past the concept-art phase before Hasbro nixed the whole shebang.
• This design was revived by Draxhall Jump when they were contracted to create the Marvel Megamorphs line for Toy Biz; Immorticon ultimately became the Hulk toy.
