What the fuck did you read?
The narration stopped just short of someone stepping in and saying "this just in....we have breaking news that when Superman is no longer holding back, he can become virtually limitless when necessary."
Of course, I'm a drooling idiot fanboy, but that was one step short of "Angier Hul get, stronger Hulk get" - except switch in a square -jawed "mister I'm not holding back any longer"
The WHOLE story arc nothing could touch H'el. Supergirl, who had a drag out fight with Wonder Woman - the second most powerful being on the earth who is so powerful that just the thought of her and Superman together made the government put together a group of psychotic criminals and Martian Manhunter as a counter just in case (cause Stormwatch would just consider it beneath them) - bounced off of H'el and nearly hurt herself fighting him
H'el nearly killed Superboy with a hand wave and even Wonder Woman asked the rest of the league - who could do nothing to even scratch him - "how do we stop a being so powerful." WW, the same WW that had a good fight with Supergirl - who just bounced off of H'el's chest like a nerf ball
Superman flew from 1 light year approximately (cause I'm a geek and they said Superman was about 180,000 miles away from earth - which is 6,000 miles away from a light year) - to go fight a guy who he couldn't even touch for the majority of the story arc, until he "stopped holding back and dropped H'el and bloodied and dropped him in two punches"
flew in in about a second to save everyone's collective hide and punched H'el so hard that Cyborg and Batman were shaken in the JLA satellite about a half light year orbiting the earth
then a sexy doctor dressed in lingerie who lives in the center of the earth walks out and states to make it even more clear - "Superman is no longer holding back - his power levels are even way bitching higher than when I measured them - which by the way he was benchpressing the earth and we couldn't find any more weight without trying to suck in another dimesnion"
So a punch from Superman rattled batman's teeth 120,000 miles away and Cyborg just said -"ain' that some shit."
All that was missing was asplash page saying "attention readers - Superman is no longer, we repeat no longer - holding back!"
and you're saying "whoa hold on there folks, this could be just like anyone else taking a red bull and looking steely eyed?"
I admit that on occasion I've missed the sublte imagery and themes of deftly written stories - such as the golden thread chapter in a tale of two cities -
This - was not subtle
I repeat - a sexy doctor in lingerie came out with a chart - with a panel looking directly at the reader and said' Superman is no longer holding back and boy is he off the charts"
I don't think anything short of a heart to heart talk with the writer would convince you
