Yeah, just climb around on that thing's corpse, that seems safe.

Despite its origins as a toy tie-in, this book tried to get away from the traditional (and hackneyed) space-opera; yet this issue's cover seems inspired by the "Space Jockey" from Alien. From 1985, Micronauts #11, "Failures of the Heart" Written by Peter B. Gillis, pencils by Kelley Jones, inks by Danny Bulanadi.

Attempting to breech the Spacewall separating them from their usual section of the Microverse, the 'Nauts had suffered a devasting loss the previous issue: confronted by a Time Traveler, Commander Rann had felt something amiss, evil about it, and ordered an attack. That failed, as the Time Traveler devastated the fleet of their allies, the alien Confluence. Marionette had been injured, her legs paralyzed; while Rann was left old, and seemingly broken. When the remaining Confluence make to return home, Rann asks to go with them, since he could not fight the Enigma Force. He wanted to spend his remaining days communing with the so-called Dreaming Star; which Mari thinks is him quitting on the team, her, life, everything. She's furious at Rann, but just didn't want to lose him.

Acroyear steps up in the aftermath of Rann's departure; conveniently in time for them to scan Acroyear ships on the other side of the Spacewall. His wife Cilicia and their people still were sore over the destruction of their homeworld Spartak in the war against Baron Karza, and considered him a traitor. Still, separated by the Spacewall, neither of them could do anything about it. The Acroyear people did still owe Mari an oath, so Cilicia agrees to aid them for that if nothing else; and advises of a massive structure on the Spacewall itself. Within it, Bug finds a massive corpse, and Huntaar uses his unusual (and somewhat disturbing) powers to let it speak through him: an advanced alien race, millenia ago, strove to breach the wall, but never could, eventually succumbing to genetic mutations and dying out.

Still, the station had built up power for centuries since, enough to breech the wall? Or enough for Acroyear to take a shot across the bow of the Acroyear fleet, to get their attention: he just wanted to ask Cilicia if she still loved him. Unfortunately, the shockwave from the Enigma Force catches up to them, damaging the alien station, and Acroyear is forced to make a final betrayal: using his royal command codes, to order the Acroyear fleet to retreat and avoid destruction. Still, knowing it was the right thing to do, Acroyear returns to the Micronauts; only for them to be confronted by Scion, who demands leadership of the team...!

I think the entire team had pretty severe PTSD at this point; although I don't think that was widely recognized as a thing at the time. Rann would return, and Scion would be a jerk for the rest of the run, but I think Acroyear would struggle to get a final bit of closure before the series wrapped and Marvel lost the rights to him.
