H3-A:
Is it normal for "Infinite Power" to be scaled in such a way? At first glance I would dismiss a phrase like that as being unusuable for scaling, but if Wiki convention is to scale it a certain way, then I suppose I'd have to concede to that.
Superman and Steel move a tesseract(Superman: The Man of Steel Vol. 1 #100, May 2000)
I'm a little iffy on this but I am willing to give it a soft yes for now. My concern is that the iteration of this infinite space -- being inside a finite device -- subjects it to a lot of wonkiness that I don't think should necessarily scale to 3-A. I would be willing to see it as supporting evidence, but in a vacuum I would feel comfortable using this as a 3-A upgrade unto itself.
I'm also iffy on this. Point blank the description is inaccurate, it doesn't say anything about "one punch" and I think it's really important to describe a scan accurately because most people will just glance at the description and not read the actual scan. What it says is:
"The phantom zone trembles under the weight of this fight."
To me, this is too vague to assign "significantly affects" to Superman, and at best the responsibility is spread out over all participants in the fight. I don't think this is usable in my opinion.
L2-C:
It appears as though Spectre is largely responsible for this, no? "Huh? The big guy is pumping
more energy into me! Getting bigger! Cant hold it in!"
The others contributed, but I wouldn't use this as a feat for them, IMO.
Infinite-Man's power
can sculpt space-time, could
destroy the Universe, including the timestream (Legionnaires Vol. 1 #18, September 1994), and
has the energies of space and time (Superboy and the Legion of Super-Heroes Vol. 1 #233, November 1977)
The only part of this that I would see as being L2-C is "destroy the universe, including the timestream" but the scan doesn't appear to say that. It says that Mordru and Glorith will finally lay claim to the universe, but "lay claim" is not really "destroy" and I am not sure how this scales to Infinite Man?
I don't think Martian Manhunter calling energy "limitless" should be used for a L2-C feat. Phrases like that are too subject to hyperbole for me, personally. The self-destruction clearly wasn't a L2-C feat as all it did was kill a few guys. The chains holding superman aren't damaged, the city he's in isn't completely obliterated. This just clearly isn't an L2-C feat.
Superman
survives the collapse of the universe. (Superman: Where Is Thy Sting, 2001)
This seems less like a durability feat and more like cosmic wonkiness involving Superman. Do we really feel like the best way to assess this situation is that it happened because of Superman's durability? I don't think this is "Superman surviving the collapse of the universe" in a way that involves him being L2-C.
Superman
fights and takes hits from the Entropy Aegis while explicitly stated to be holding back. (Superman: The Man of Steel #134, March 2003). The Entropy Aegis is stated to be the power to
remake and destroy the universe. (Superman Versus Darkseid: Apokolips Now, March 2003)
He says "You get to keep John Henry Irons
and the Entropy Aegis
and the power to remake and destroy the universe." I don't think this scan justifies scaling the armor to L2-C. If you read the whole Entropy Aegis run, you really don't get the impression that it's anything like that.
I think this could be 3-A, but frankly, I really don't think Nebula Man and all of his opponents should scale to Tier 2 or 3 just because he's called a living universe.
Superman's clash with his Golden Age counterpart
shattered the boundaries of Space-Time and changed timelines (Superman Vol. 2 #226, April 2006, Action Comics Vol. 1 #836, April 2006, Adventures of Superman Vol. 1 #649, April 2006)
I think this is a decent feat, but might require a bit more examination. Depending on how we assess the other evidence, some of which I think is clearly not supportive of Tier 2 (such as the Aztek explosion), it may not be enough by itself to justify an upgrade.
2-C:
Did some research on this. It seems like this ability was pretty much entirely based on the Materioptikon/Dreamstone. The Dreamstone has part of the power of Dream of the Endless, and can create realities, that much is legit. The question becomes: Is it best to interpret Red King's possession of the stone as translating into a comparable level of combat prowess? Can he channel the dreamstone -- the purpose of which is dreaming realities -- into a blast to hit a single person? I am not so sure, but I'm open to discussion.
Superman
separates two worlds(Batman/Superman Vol. 2 #21, October 2021)
I think the question should be asked: Is Superman able to do this because of 2-C power, or is it a function of being in the Archive of Worlds which has realities in the form of tapes?
Superman one shot Auteur.io(Batman/Superman Vol. 2 #21, October 2021)
Dr. Atom/Alexander Luthor also injured Auteur.io with a bomb. They also injured him with a tornado cannon. He wore armor and had robots that fought on his behalf. Auteur.io definitely has powerful reality-warping capabilities, but IMO it's clear that this does not translate to his head-to-head combat abilities. I don't think this should be interpreted as 2-C.
2-C, possibly 2-A
Most of this stuff is scaling to other characters so I'd have to more thoroughly examine their profiles and give my opinion.
Overall, unfortunately I have to say I do not find the totality of evidence particularly compelling. It seems a bit like a "throw everything at the wall and see what sticks" approach which is not ideal. The Aztek feat, for example, is so very clearly not L2-C, and feats like that really should've been pruned before making it to the final post.
