Achilles.

I’m not familiar with 3 or 5, but he clears the rest.

Might stop at 3, dude has vampire powers.

He'd have to behead the zombie Mountain. Mountain wouldn't touch him unless he tripped on a stick or got tired

Calibos isn't as great a fighter, but his superhuman stats might be enough

Zombie Mountain sucks ass and his armour is made of cardboard. Achilles would roll him as long as he didn't get grabbed.

Quintus can outrun explosions and is ridiculously stronger than than Achilles. It would be a complete shit stomp.
