Captain Marvel I#44 (May, 1976)

Powers/Abilities: Originally mortal beings, the Underground members progressively lost limbs in battle, and they were replaced with bionic parts, transforming them into cyborgs.When last seen the Underground members were more machine than organic tissue.

    They wore armor, including helmets, apparently composed of an unidentified metal (some of their armor may have been part of their bionic parts.

    They likely possessed some degree of superhuman strength and durability.

    A number of them carried staffs or spears and/or used energy rifles. denebiv-underground-cmi44-ambush

(Captain Marvel I#44 (fb) - BTS) - Kree Null-Trons devastated the Kree frontier outpost Deneb IV.

(Captain Marvel I#45 (fb) - BTS) - Rambu and at least he man who would become their General were dispatched to Deneb IV to fight against the Null-Trons. 

(Captain Marvel I#45 (fb) - BTS) - The Underground was formed on Deneb IV to rid their world of the Null-Trons. denebiv-underground-cmi44-overwhelm

(Captain Marvel I#45 (fb) - BTS) - While the Underground's members were once fully human, over time they gradually lost their mortal limbs and had them replaced with cybernetics. 
    Eventually they were mostly machine. Their General existed only as a head and neck grafted to the body of a Null-Tron.

(Captain Marvel I#45 (fb) - BTS) - Seeking to absorb the Destiny Force (as it was later called) from the human Rick Jones, the Supreme Intelligence engineered a convoluted plot, involving arranging for the General to obtain the Mind Gem (see comments) and use it to condition Jones and Mar-Vell for this purpose.

(Captain Marvel I#41 - BTS / Captain Marvel I#45 (fb) - BTS) - The Supreme Intelligence also increased the power to the Null-Trons to make their danger to Deneb IV more acute.

(Captain Marvel I#41 / Captain Marvel I#45 (fb) - BTS) - Rambu tripped on loose soil, uncovering the Mind Gem (see comments).

(Captain Marvel I#45 (fb) - BTS) - Rambu showed the gem to the General, who said its strange power would be their salvation: No more new limbs, no more watching themselves becoming more and more machine.

(Captain Marvel I#44) - Captain Marvel arrived with the seemingly dyring Rick on Deneb IV and found it to have been destroyed and its people slaughtered. Mar-Vell located the central medical facility and placed Rick within one of its standardized life-support chambers.

    Surveying the city and finding no other living beings, Mar-Vell then discovered the Null-Trons, realized them to be the cause of the devastation, and fled when they attacked him. denebiv-underground-cmi44-carrymarv

(Captain Marvel I#44 (fb) - BTS) - Members of the Underground took Rick to the General.

(Captain Marvel I#44) - After finding Rick missing, Mar-Vell was assaulted and subdued by members of the Underground -- presumably including a helmeted Rambu -- who brought him before the Head of the Underground, where Rick was being held. The General told Marvel that he wanted them both to not only join but to lead the Underground.
    In exchange, the General would cure them of the disease he had discovered in Rick' brain as Rick and Mar-Vell's minds were merging into one.

(Captain Marvel I#45) - The General revealed his origins and their progressively losing the battle against the Null-Trons, but refused to reveal anything further about his plans unless Mar-Vell agreed to his proposal, as he could not risk compromising his plans otherwise. 

    After Mar-Vell agreed to the General's offer, the General told him of the Mind Gem. Acting under the General's presumably previous instructions, Rambu and a number of the other Underground members removed Jones from his life support chamber and physically hurled him into the Mind Gem. The General then instructed Mar-Vell to follow Jones into the Gem or forfeit all hope, and Mar-Vell entered the Gem as well.

    Within the Mind Gem, Rick and Mar-Vell battled to preserve their own identities, and -- and, as the General had planned -- the Mind Gem transmitted the energies of their fight to the Underground who then assaulted the Null-Trons, even mirroring Mar-Vell and Jones' dialog.

    Rambu met with the General, who told him that their people were rallying and that the two inside the gem were beginning to formulate battle strategies. When the General noted that they would at last be free of their eternal war, Rambu asked whether he meant they would win. However, the General told Rambu that his pride and humanity were nuisances, after which he noted that they had been dispatched there to die: While cyborgs were the elite, they were all expandable, although very slowly so. 

The General elaborated that when one of the two in the Mind Gem won, the Underground would win their war against the Null-Trons. Rambu questioned how the General knew which one would win, but the General replied that it did not matter which one won, as whatever the outcome, the war against the Null-Trons would be over. He clarified that whether they greeted the evening as conquerors or the conquered, they would know peace: "That is what I promised and what I will deliver."

    Rambu was outraged that his General had no concern whether they won or lost, but when he denounced the General, the General swatted him down with his powerful Null-Tron arms.


(Captain Marvel I#45 - BTS) - Mar-Vell and Jones' fierce battle led the Underground to gain the upper hand against the Null-Trons, until the two realized what they were doing to each other and paused, at which point the Underground and Null-Trons' struggles halted as well. 


(Captain Marvel I#45) - As the General stared into Mind Gem, awaiting the next assault, which he knew would soon occur, Rambu struggled to his feet and began pounding on the Mind Gem, accusing "this soul gem" of being the cause of their misery. The assault was transmitted to both Mar-Vell and Jones inside the gem; and, through them, to the warring Underground and Null-Trons forces, who toppled to the ground. 

    Fawn -- a manifestation of his own subconsciousness created via his connection to the Nega-Bands -- subsequently introduced herself to Rambu and then noted that while her goal was to save Jones, it would save Rambu's cause as well. Her presence giving him understanding of what he needed to do, Rambu took Fawn's hand and dove into the Mind Gem with her, ignoring as the General cried out in impotent rage.

(Captain Marvel I#45) - Fawn and Rambu stopped Mar-Vell and Jones from fighting, and Fawn granted Mar-Vell understanding that he and Jones were merely evolving rather than merging.

    Fawn then led Rick Jones, Mar-Vell, and Rambu with her to escape "this jewel of madness and death."

(Captain Marvel I#46 (fb) - BTS) - The quartet departed the Mind Gem, the subterranean sancturary, and Deneb IV, traveling to confront the Supreme Intelligence.

Comments: Created by Steve Englehart and Al Milgrom.

    Rambu and the General/Head discuss being dispatched to Deneb IV. Rambu says "we," so it is at least Rambu and the General, but it is not clear how many others were sent. I would think it likely that SOME of the Underground were residents of Deneb IV and that some were dispatched to aid them, but that is not confirmed.
     When Rambu's assault on the Mind Gem was transmitted through it via Jones and Mar-Vell's connection to those fighting, the Null-Trons noted that the Denebians were toppling as were they. That would SEEM to indicate that many of Underground members were Denebians.
    That being said, the Null-Trons hated all life equally, and they may not have just considered any at-least-partially organic beings as Denebians.

    Captain Marvel I#46 describes Rambu as "last of vanquished cyborg army."
    The General was last "seen" crying out in futile protest as Rambu and Fawn entered the Mind Gem.
        We did not see the Underground army after the last scene where they toppled when Rambu was striking the Mind Gem, but I wonder if this is meant to indicate that when the fight between Rick and Mar-Vell ceased (or when they departed the Mind Gem) that the cyborg army was caught unawares and wiped out by the Null-Trons?

    Only one city was seen when Mar-Vell proclaimed Deneb IV has been destroyed.

It is a common plot/point in comics to show only one location but to have the assumption that the whole planet was similarly affected.
But we don't know that. Perhaps there was one or perhaps many cities not devastated by the Null-Trons.

We saw perhaps a few dozen members of the Underground battling the Null-Trons, but there may well have been many more of them based across the planet.

    See the Deneb IV profile's comments for further discussion of Deneb IV's location and the Mind Gem.

Captain Marvel I#44 cover's scene didn't happen in the comics, as Marv only faced the bland solid silver-armored Underground, but it's the best image of the warrior force nonetheless, so I included it at the bottom.

The Underground of Deneb IV has no known connections to:

subterranean sanctuary

denebiv-underground-computerbankdenebiv-underground-cmi44-stairsdenebiv-underground-cmi45pg4pan6     At some point, the Underground established their subterran sanctuary in the rocky caverns beneath the surface of Deneb IV.

     The General/Head was based out of this sanctuary.

     The sanctuary contained at least some computer banks of an undetermined nature.

     After discovery the Mind Gem, Rambu brought it to the General in the sanctuary.

      After Captain Marvel and Rick Jones arrived on Deneb IV and Mar-Vell placed the seemingly dying Rick in a life-support chamber, the Underground took Rick and a life-support chamber into the sanctuary, after which they overwhelmed Mar-Vell and brought him there as well.

     It was from the sanctuary that the General sent Rick and Mar-Vell into the Mind Gem, although they eventually escaped with aid by Rambu and Fawn, and they departed the sanctuary and Deneb IV altogether.
