The winner is the one that can exploit his surrounding. If you put all of them in their full battlegear the one that will be triumphant in the end would be Kyvaan Shrike.

Why? Because the only way you can see him is when he tears you apart with his claw. The only one who can defeat him would be Ragnar who with his greatly enhanced sense of smell, agility and blood lust (due to the canis helix) will give him a great advantage. The only way that i can see Ragnar losing is when his sense of smell and hearing is muffled by helmet.

Cato loses because he is too deeply entrenched within the Codex. Belial and Lysander would probably lose after the battle start because terminator armor is slow compared to normal power armor.So the advantage goes to the captain that is faster and stealthier (Ragnar and Kayvaan).
