people saying kratos is dumb are stupid. He's acually smart and lead armies therefore good with tactics.
Its hard to say if they can fit in each others world, picture kratos in links world is just wrong however i can picture link in kratos world...lol but link would get massacred.
one character i can picture in both worlds and survive is...Dante.
he talks, smart, smooth and cocky
but also brutal, strong and stylish.
