In 1967, the "Who's stronger?" debates that readers often engaged in which attempted to establish whether X character was stronger than Y were going, er, strong in the letters pages of Marvel titles, probably because there were so few super-powered heroes to choose from at the time. It was a subject that everyone seemed to have an opinion on, and the back-and-forths between readers were harmless and good-natured. For the most part, Marvel staff that responded in print remained coy and neutral as far as providing a definitive, set-in-stone answer to such a question; after all, the interest and enthusiasm being generated by these debates were all a publisher could ask for, helping to maintain "Marvel mania" as well as contribute to the promotion of titles that some readers may not have sampled yet. Keeping those embers burning probably seemed more sensible than dousing them prematurely.
At the time, the high bar in strength was set with Thor, even as
a battle between himself and the Hulk in early '65 sought to make fans of
both characters happy. Two years earlier, though, the big debate was between
the Hulk and the Thing. You could have knocked me over with a feather when Marvel actually (kinda sorta) settled the matter in
the Q & A segment of the '63
Fantastic Four Annual. But look how cleverly their response is worded--leaving room for dissent, while also describing how the Thing compensates for the Hulk's strength advantage:
So while the answer was satisfactory, no one could really point to it and say that Marvel had put the issue to rest. (I'd say FF #25 did that.)
In '67, it was interesting to see the new kid on the block take himself out of the running completely, though admittedly there couldn't really be much argument on the point given his competition at the time.
What a difference almost a decade makes, as Mark Gruenwald and artist Bob Layton supplement the 1981
Amazing Spider-Man Annual with a more extensive chart that ranks Spider-Man's strength with a more broad assembly of heroes that had since been introduced. And even though the "Who's stronger?" debate has long since wound down, I found myself shifting a few characters around in instances where I didn't totally agree with their placement.
For instance, if Iron Man is going to use the argument that he belongs in the top category because he can charge his armor to attain that strength level (if only for a few moments), you can make the same case for the Silver Surfer, who can also use his power to
increase his physical strength. Regardless, perhaps Iron Man and Namor need to be in same category, since they've
clearly demonstrated they're well-matched on land. And since Namor has gone toe-to-toe with the Hulk in
both environments, he should probably be moved up to the top tier. (I'm still on the fence about it.)
I also have trouble believing that Spider-Man could survive the weight of a jetliner wing falling on him, as
Colossus did, to say nothing of brushing off the impact and resuming the fight with his foe. I'd move Colossus up a notch--along with the Valkyrie, who should be able to more than hold her own against Doc Samson. She can be replaced with the Beast--he well outclasses Captain America and several others in the "mediumweights" in strength.
