Also i think everyone should appreciate the fact that the colossus of rhodes is a massive....metal construct, not a lump of crumbly rock from a mountain and at the same time, appreciate the fact that the colossus overall tonnage is high, but if it could move and it used the weight and strength of its body to bring its food down on Kratos the weight would be immense, the weight of a human being for example falling on you is not as heavy as if that human being actually projected its weight into a body slam purposely using the whole weight to its advanatage, the same with this colossus of rhodes.
Kratos would with ease survive anything M2 could possibly send at him and more besides and even if M2 flies Kratos has lightnig bolts of Zeus, the blade of Olmypus beams and the bow.
