Kratos is the most violent, angry and powerful character in pretty much all video games. (See how he um... dealt with the Furies at the very end... major anger issues... um yeah.) Anyway, if somehow you can come up with a scenario where the entire SSB team is able to take Kratos.... who by the way obtained the ability to reverse time in Acension (yeah, this is what the Smash Bros are dealing with here) they will be far too exhausted to take the rest of PAS and Cole and Evil Cole would clean up who are immune to PIkachu. Jax, Drake, Ratchet, Dante and the boy from Killzone would lay down a barrage of oppressive fire that would kill anything else and and Fat Princess would eat Gigglypuff. Game Set and Match.
