Superman
Superman's strength operates at a scale that defies measurement. Canonical feats include bench-pressing the weight of the Earth for five consecutive days without rest, moving planets through direct physical force, and in certain continuities, lifting objects of theoretically infinite mass.
Under optimal solar saturation, particularly exposure to blue star radiation, Superman's strength multiplies exponentially beyond baseline levels. He has shattered moons, held black holes, and physically contested with beings of multiversal significance. His raw physical output represents the upper boundary of depicted superhuman strength in mainstream comics.
Thor
Thor's divine strength manifests through both physical might and the mystic amplification provided by Mjolnir. He has destroyed planets through hammer strikes, shattered the armour of Celestials, and physically contested with the Hulk at his most enraged states.
The God of Thunder has survived and returned blows from Galactus, matched strength with Hercules across millennia of competition, and in his Rune King incarnation, wielded power sufficient to threaten cosmic entities. His strength derives from divine essence rather than external energy sources, providing consistent output regardless of environmental conditions.
