That doesn't really work because Eternity is the cosmos itself, and there is no higher personification of it that ranks above him.
God is everything and
nothing in Marvel (though obviously this probably isn't the same as Above-All-Others), which would include the multiverse, and as I showed in the scan there are more facets to the order of the multiverse than Eternity alone, like entropy and probability. So my point was that it doesn't matter that Eternity is the concept of the multiverse.
Also, let's just analyse the claim here. Warlock doesn't say 'Thanos is the personification of the multiverse', he says 'Thanos is the personification of all realities'. Wouldn't that also contradict each Eternity being the concept of said realities by your logic? And wouldn't that not necessarily even cover the Superflow and Neutral Zone?
And even then, Thanos has the Astral Regulator. Warlock didn't say Thanos gained this level from All-Above-Others, so why can't we assume that he absorbed every single Eternity as well as All-Above-Others (whose pan-dimensional would at least give him that range)? Hell, in order to become all realities in a
similar fashion to one reality, he'd have to absorb the associated aspects in those realities. So he'd have absorbed all Eternities, TLTs, etc anyway.
The Living Tribunal isn't really above Multi-Eternity in ranking or in authority, and in fact applying those terms to him is incorrect because he is not part of the hierarchy in which those things mean anything in the first place. The hierarchy is part of him, not vice-versa.
Ok, then. But his role in the cosmic hierarchy is still to judge all realities. So being TOAA's representative without being more powerful than Eternity is still quite possible due to his role.
(Also the last scan you posted is Thanos saying that the aftermath of his fight with the Tribunal and AAO affects all realities, so, I don't know what it's meant to show)
What it's meant to show is that this was likely universal TLT anyway. If there is a multiversal TLT in Starlin's story,
It didn't say the battle affected all realities, it said a new dawn would fall upon them after Thanos won. With your scan in mind, this refers to the fact that Thanos became the multiverse.
What says that's Multi-Eternity? What we know from that scan (and why I use it) is that Eternity is the one of the dominant forces of existence (which applies on a universal scale), but it doesn't say this is Multi-Eternity and doesn't exactly make sense when any Eternity would have to use an M-Body to even be
inaccurately seen by beings on this level.
And even then, those are just floating head projections.
You're missing the point.
I'm not missing the point because my point is that being someone's best servant doesn't make your their most powerful servant.
I don't think it teaming up in a fight with an immeasurably more powerful being perpetuates anything.
which evidently is still a thing to Starlin.
Literally all of Starlin's depictions (as far back as Infinity War) involve universal Eternities and universal TLTs, though.
This is what I'm trying to say.
