i dont think colossus is completely outclassed in strength unless we count the mythical and astronomical feats.....
i dont see herc bending his arms ala hulk.......
but i do see herc out maneuvering him in grappling close quarter fight...
i see it like a heavy weight having the advantage on someone by like 20 lbs maybe 30.... still conceivable for colossus to win just not likely.
i think herc has him beat on godly stats in reflex reaction time and slight increase in strength and millenium worth of fighting/brawling
1.herc and thor used blunt force to close a tear in space and time from either end of the portal from earth and olympus.
2. he held the heavens.
3. he held the earth to gave atlas a break
4. he and thor almost knock te earth out of orbit during an armwresting match.
5.he literally pull mathattan together after the effect of war world hulk
6.he pulled mathattan back to it original position after it was removed by alens.
7.he toss godzila in mid air like it was nothing.
8.he beat the skrull skyfather with physical strength
9.he literally removed a mountain from in his way while in a hurry
10.he lifted shield helicarrier with ease something even the sentry struggle with.
