Heh, technically/strictly speaking, I'm pretty sure that Adam is the only human heavy weight in the top hero class.
Thor, Hyperion, Surfer aren't human. Hulk only has muscle, while Wonder Man, Cap Britain are usually depicted as one level below the rest. Not sure where Captain Marvel/Carol is these days, though
Sentry is above them, of course, though where he falls on the hero/alive scale varies from one writer to the next.
Actually, technically, Hyperion is human. Eternals are merely an advanced offshoot of the human strain thanks to Celestial experimentation. Chronos would further inadvertently elevate some of the group to cosmic levels by virtue of his disastrous experiment with cosmic energy. But that doesn't make them any less human, even if some of them have godlike powers.
Blue Marvel doesn't have Adam Warlock's ability to spin a cosmic cocoon and emerge as something better, unfortunately. But I can't let go of what he did to the Shaper of Worlds back in the Ultimates series. I was really hoping that Ewing would have somehow found a way to merge Adam and the Shaper's Ghost. The Shaper still has the imprint of several vicious, cunning and exacting handlers on his personality matrix. Never mind the powers, which would be off the scale, but just having that edge added to Adam's DNA would improve him by leaps and bounds. Adam is 80+ years old, but has never had his mind or body betray him. Maybe a permanent symbiosis with the Shaper of Worlds could introduce some new twists and turns that readers might find appealing?
It's only been a more or less recent rewriting of the lore that posits that other Celestials experiments were also called Eternals. (Take the Kree Eternals, for instance.) But originally, the term was reserved for only Earth's test subjects. Divergent Earths included. Until they establish that Hyperion is a Galadorian Eternal or something like that, I'm going to jot him down as genetically homo-based.
But I get what you are saying about the origin of all Hyperions being analogous to the Kryptonians. Marvel just has to pin that down for me, if they're going to continue to say that he's both an alien and an Eternal. Technically, Starfox and Thanos are aliens and Eternals. But both of them are human at the end of the day.
I would love to know what Adam thinks of his sacrifice in light of the racist currently occupying the White House. Dying to know. Not a story Marvel would tell, but a one-shot featuring Adam, who is somehow forced to work for He Who Shall Not Be Named by Executive Order would make my day.
The thing is, the MU presidents as a whole were probably a lot worse than any real life ones. In the MU we've had things like Sentinals and negative zone prisons. Not to mention that whole thing with Nixon. So by comparrison I almost think it wouldn't be that big a deal, since most heroes are probably used to a president in the MU who does a lot of things they don't necessarily agree with.
