Dante and Raiden are far more powerful than Kratos.

Kratos can change the fate too. No matter how much you go back, once your fate is sealed your outcome will be the same.

Also if you let the Smash roster watch what happened to Poseidon I doubt they would be even up to the challenge:).

Though most of the All Stars roster is potatos so Smash roster may win considering their advantage in numbers. Drake, Sir Daniel etc. would be out in the first second.

See, here's the problem with that: Ratchet has a shield that can protect him from all damage as well. And it's not limited by mana like Link's shield, it's only limited by his ammo, and using his PDA Ratchet can restock ammo all the time, mid-battle. So Donkey Kong, Link and Ganon could try as hard as they want, but they still would literally not be able to touch Ratchet. Meanwhile, Ratchet can blow Donkey Kong to smithereens, and send Ganon along with Link to another dimension. Bam, and they're out. Now we're back to the rest of the SSB crew dancing, while Ratchet and the rest blow them to shits, and Ratchet can simply send any 'invincible' charachter to a different dimension. Ratchet is to OP, he could pretty much solo the entire battle, because he can't be hurt due to his shield, and all the enemies are forced to dance and wait until Ratchet kills them, before Ratchet sends the 'invincible' guys to another dimension.

From the OP: "Super Smash Bros gets it's Melee roster, but as they appear in 4" AKA the characthers in Melee, but as they appear in 4, so no Shulk, as he's not in melee, and no Palutena either. Besides, Clank can also reset the universe (and destroy it, at that), so they're tied there. Also Ratchet doesn't actually need to restock, the battle would be over before the total ammo capacity of the shield runs out, because Ratchet could simply send all of them to another dimension. And even if we include Palutena, PSAS also has Zeuz, which is guess what, a god.

So there are two possibilites, depending on what powers Palutena has. 1. PSAS wins because they send immortals (including Palutena) to another dimension, while non-immortals are just blown to shits. 2. If it's for some reason impossible to send Palutena to another dimension, then it's a tie.

No I didn't read your link. Your link isn't some infailable proof, it simply links to another forum where they've had this same discussion, and there's 823 posts there, and I don't intend to sit down and read all of them.

If this is such a stomp as people are saying, then the Smash Bros will need numbers. Super Smash Bros 4 roster it is!
