For those of you saying Kratos will win because he's killed 'gods', have you forgotten how many smash characters have done that as well?
Pit has slain many in his time.
Palutena and Rosalina are goddesses.
Ike has slain a goddess in his game, two if you count Yune dying as a result.
Kirby if you count 02.
You say Kratos is the god of war? So what, shulk wields the 'god slaying sword'
Melee roster means no Pit, Palutena, Rosalina, Ike, or Shulk.
I think Shulk is the only one who could go toe-to-toe with Kratos. Kratos would simply overpower Pit, Palutena, Rosalin, and Ike.
