rayden easy. due to storyline, rayden can't be taken down by anyone less than a fellow god or by, count em, two powerful sorcerers.
rayden easily destroys kratos.
to say that rayden obliterates zeus but not kratos is lunacy.
although kratos would comeback for round two with the power of pandoras box and then we have ourselves a different story.
so in a recap...
rayden wins the battle
kratos wins the war
rayden: you challange me!? after i've already destroyed you!? this is madness!
kratos: madness? ...THIS IS SPARTA!!!
