Current Thor(classic feats still count) and pre 52 Superman
2. The Mighty Thor and Superman are the heavy-hitters of their respective universes, so its expected that this is without question the most discussed versus debate amongst comic book fans. No other versus battle comes close to being talked about as much than this one. Try to start a “Superman vs Thor” thread on any forum(like here) and the first response is sure to be: “Not this again”.
Thor has lifted the Midgard Serpent, who was so large it could coil itself around Earth several times and crush it within it's grip, shattered planets with the force of his blows, stalemate Hulk's strength for an entire hour(who is Marvel's strongest character), crumbled uru metal into dust with his bare hands,etc.
Superman has moved the gears of a machine that dwarfed the entire Earth/Moon system itself, fight powerhouses like Doomsday, defeat Mongul in 60 seconds with nothing but his fists, lifted the Eath with the help of Martian Manhunter and Wonder Woman, etc.
Final Analysis: Being the heavy hitters of their respective universes, this is a tie. As neither, if written consistently, would show upper limits to their strength.
Thor has caught up the godling Zefra, created trenches before his enemy to which not even Quicksilver could react, and can travel as fast as the lightning he commands. Perhaps his most impressive travel speed feat was when he caught up to Ego, the living planet, who was moving in hyperspace. Meaning Thor had to have been traveling at least three times faster to overtake Ego in speed(Source for Ego: Astonishing Thor#2).
Superman has traveled across continents in seconds, traveled around the world over 3 times in less the blink of eye, kept up with speedsters such as Barry Allen, although not as fast as Barry nor even as Wally,(source for race with Barry: The Flash Rebirth #3),etc.
Final Analysis: When it comes down to it, thanks to mjolnir, Thor can travel at FTL speeds that surpass even Superman. This goes to Thor.
Not much to say here, Superman has nano-second reaction time, and has blitzed characters ranging from Gog to Mongul and everyone in between(even Doomsday).
Although Thor has struck down a moving Quicksilver and claimed to have fought enemies faster than him and possesses micro-second reaction time, Thor's lack of reactionary speed feats gives this area to Superman.
Winner: Superman, by a long shot.
It's already known that both Thor and Superman possess limitless stamina. However:
Final Analysis: Due to Thor's stamina deriving from his physiology(internal), and Superman's stamina deriving from solar energy(external). All Thor has to do is get Superman to fight under any other sun but yellow, and Superman will drain his solar energy reserves, and thus, tire, very quickly. This goes to Thor.
Thor has withstood unrestrained blows from Hulk, on multiple occasions(as I said before, Marvel's strongest character), punches from Gladiator(one of the more powerful Superman clones), nuclear bombs(that's right multiple) at point blank range with no injury, a Doomsday Bomb(capable of destroying an entire planet), sitting in the core of the sun, Ghost Rider's hellfire(Thor was actually immune to it), temperatures 1,000 times hotter than the sun and blasts from the Asgardian Destroyer Armor, and even attacks from the all-powerful race known as the Celestials(Fourth Host, to be exact).
Superman has withstood nuclear explosions, laser attacks powered by the core of planets, bullets, temperature extremes(as hot as the surface of the sun without even the slightest discomfort), and has even withstood Darkseid's omega beams, a feat previously thought to be impossible, planets colliding, and even a supernova-which destroyed all of the planets in the surrounding solar system(although the explosion did knock Superman out, he had no visible damage)
Final Analysis: Being able to dish out attacks from beings who can warp reality at a mere whim vs being able to survive a supernova, I give the durability to Thor, slightly.
Thor can heal from any injury instantly.....only with magical assistance or the Odin Force.
Superman can heal from any injury instantly due to his solar powered healing factor.
Final Analysis: Due to their being no Odin Force/magical assistance for Thor and no kryptonite for Superman, the winner is Superman.
Thor has a vast arsenal of different powers and abilities and I'm not about to sit here and even attempt to list them all. I'm only going to discuss a few that would relevant in battle.
Thor can transmute elements, teleport Superman to any location he desires, use alpha particles to disintegrate Superman in one shot, absorb the solar energy from Superman's cells and cause him to lose his solar based powers, draw out Superman's life force and weaken Superman, etc. And on a defensive note, with the ability to create a force field that is capable of containing energy that can destroy 1/5 of the entire universe, Superman isn't getting through Thor's barrier defenses if Thor wills it.
Thanks to mjolnir, the overall power(due to versatility and sheer destructiveness), goes to Thor.
