The 700 level on my scale is reserved for feats that would register as hard work for Marvel Comics top tiers.

The success of the "Battle Royale" philosophy of Marvel Comics now shapes nearly every superhero comic on the market. The challenge the hero must overcome is nearly always the physical prowess of the villain.
Part of this is because the villain is usually physically superior to the hero in some way. This holds true even in the cases of major heavies like Namor, Thor, Captain Marvel, and today's Superman. For instance Namor and Thor often match against a villainous version of the Hulk. Captain Marvel against Black Adam. Superman against Superboy-Prime.
In each case villain or anti-hero has a physical edge on the hero; the hero must find some way to compensate for that difference in force.
