Transformers: Regeneration One #94

CYBERTRON UNDER SIEGE! As BLUDGEON's Blitz Engines wreak havoc, the AUTOBOTS struggle to muster a response to a threat that feels all too close to home! But their "greatest warrior," ULTRA MAGNUS, has problems of his own... in the shape of a fighting mad GALVATRON. It's the clash of titans you've (almost) never seen before!
