The problem is that Hercules just outmatch Colossus in every category.
Strength=Herc by milloins of miles
Speed = Herc he possessed Godspeed
Stamina = herc Limitless stamina
Fighting Skilled= Herc Superior in thor in the art of H2H combat
Agility = Hercules He easily dublicated spiderman moves in Marvel team up
Durability=Hercules According to the handbook which people usually quote to stae colossus nigh invulnerability. It state that The Sentry possessed strength and durability on par with the likes of hercules and thor. So unless colossus is more durable than the sentry and thor hercules also own him in that category. Another colossus have more appearence in comics than hercules and yet hercules have a lot of high end durability feats against top tier, herald level and even some cosmic level characters like kavoc, the stranger,an elder of the universe, a death god and even the beyonder and on the other hand colossus does not even have more than 5 high showing durability feats against top tier than how can you say he is more durable than the prince of power
