Superman's subconscious mental control over his stats suppressed his powers--including involuntary stats like vision and durability-- down. Hence his own mind crushing his body to death under Jurgens. His ttsandard levels were him supressing his power. Period.
under Robinson, Supergirl's depression depowered her and was killing her-- just due to her mindset. Kryptonite can fluctuate their stats due to thier mind. Not up for dispute. dont like it? you opinion on these characters is null and void.
The writers of the strry say you're an illiterate buffoon. H is strength was innate, but suppressed. meaning, when not supressing it, his strength level went up-- hence increased in output. By your argument when Superman goes from human level to top tier due to his mind accesssing mroe of the innate power he usually suppresse, his strength isnt increasing right? GTFOH
Further, it wasn't really everything he had. Superman had no conscious idea of his full power at that point, as Loeb/Casey/Schultz and later Johns and Busiek made clear. And even then, he was still being weakened due to Dr. Mantattan splitting him apart into Post Crisis/Nu 52 Superman.
Show superman raising his strength mentally you idiot. If he could raise his strength mentally, then it would have been shown and mentioned in thousands of comics you moron. His power surging is because he us fighting like mongul taught him idiot. Post the scan where he fought black Adam and talked about mental blocks. Then post the scan where he and mongul fought and mongul told what happened moron.
So now superman can raise his strength, speed, durability, heatvision and freeze breath by a factor of billions with his mind? HA HA HA HA HA HA HA HA HA HA HA HA!!!! watch out Galactus, tyrant and rune king Thor. This is Gold. Lol
