kratos dante & mercer vs omega(ff5) ruby weapon and emerald weapon

kratos without god powers, maxed. dante dmcI maxed. alex maxed.

time powers are limited severely.
they fight the weapons individually

1. Kratos can go RoT and pull off a flaming inferno for massive damage and reflect with the golden fleece. His Titan magics should be useful as well.

2. Dante goes Sparda on Ruby.

3. I can't see why Mercer couldn't get through this. He's overpowered and survived a Nuke. He also has no materia so the biggest threat of Emerald doesn't apply.

Both Kratos and Dante have both taken on and beaten enemies of that level, and im sure game-end Alex could match. So all 2 together? No contest.
