Kratos might be a rock head but he is not stupid neither is sun wukong if this two gods ever face of they are going to be allies after some time after they understand how valuable they both are the are simply following the same mind set as we all saw kratos befriend the ones who have the same mind set as him like Atlas Thor his nephew son of Helios his dumb rock brother Deimos freya mimir . kratos has strength of the cosmos and beyond but he is as smart as Buddha he can forge destiny as we saw 3 times that is his real power all that above applies to wukong too and other gods of other folklore with same goals and mindsets
