"We could argue all day long about who has better feats, Thor or the Silver Surfer. One could bring up the fact that Thor has gone toe to toe with a Celestial, or how the Silver Surfer has defeated Primordial gods. But we would be doing that all day long. Truth be told, the two heroes are pretty much at the same power level. But when we actually read the comics where these two heavy weights have actually fought each other, we see a different story. Thor has consistently bested the Surfer when the two have fought.
Call it PIS (Plot Induced Stupidity) if you want to, but Thor has defeated the Silver Surfer before on not just one, but several occasions. If you haven’t already, take a look at Silver Surfer #4, where Loki (Thor’s evil half brother) attempts to use the Silver Surfer to defeat Thor. He tricks the Surfer into attacking the god of thunder. During the fight, Loki even augments the Silver Surfer’s powers with his own, after which the Surfer says that he has never felt that powerful before. He also claims that Thor’s hammer is far more powerful than his own power cosmic. To quote the Silver Surfer himself, “I have seen his mallet’s magic, it is truly mightier than my cosmic force!” Also keep in mind that this comic was written by none other than Stan Lee himself. It’s hard to find a higher authority about the Marvel Universe than that.
On another occasion (Warlock and Infinity Watch #23) Thor defeated the Silver Surfer AND Adam Warlock. This occurred AFTER Thor had already beaten Beta Ray Bill and the Silver Surfer. After Bill was knocked unconscious, the Silver Surfer stood alone and was defeated, until the arrival of Adam Warlock. The two teamed up, and together they also lost and were forced to retreat.
The evidence from the comic books themselves is clear. Every time they have faced off, Thor has defeated the Silver Surfer. Even when the Surfer’s powers were augmented, or when he had help from various allies, Thor has won. This by itself is strong evidence that Thor is more powerful than the Silver Surfer, despite what Wizard magazine says. Not only that, but Thor has even defeated a hungry Galactus (The Silver Surfer’s on again, off again master, and the one who bestowed the power cosmic to the Silver Surfer) all by himself, forcing the big G to retreat. Again, I stress that Galactus was hungry (as anyone reading this probably knows, he is far weaker the longer he has gone without devouring a planet) but even still, you’re never going to see Captain America or Spiderman defeat a hungry Galactus."
SageMode: I definitely agree with this. Thor is generally underestimated in my opinion. I just wish the guy at Marvel would showcase Thor doing battle at his ABSOLUTE FULL POTENTIAL. What do you guys think?
