just dont forget that kronos from wrath of the titans was stated to be the destroyer of the universe and that he will dismantle the earth and scatter it across the universe.
judging by your answer i would say you definetly didn't watch the movie because kronos is like 1.5 kms tall even mountains are small to him that is ofcourse not mentioning that he defeated zeus and hades singlehandedly and was destroying mountains casually
Judging by your statement I would without a doubt say you didn't pay attention to the film and just louldy chewed popcorn while being amazed at the dazzle. Zeus and Hades at best were at half-strength at the point in the film, though they were likely far, far, far lower than that, considering a short battle and a few attacks drained them.
perhaps you are right about zeus and hades being weakened but the fact still stands that kronos surpasses the avengers and the xmen in terms of dc, durability, size and strength not to mention he is the universe destroyer and if you don't beleive me watch the kronos feature
tell me exactly how are they gonna scratch kronos first of all he is made of smoke and lava gettingt near him will do them more harm than they do to kronos
