Gate of Babylowned x2.
Bloodlusted? Gilgamesh gets on his magic space ship that shoots infinite nukes at the speed of thought and decimates the entire battlefield. In character? Gilgamesh stands around complaining about mongrels and how kratos isn't worth fighting because he's not a real god. Everyone else is a non-factor.
Either way i don't see the chains keeping down kratos at least not with starkiller also in the fight. In truth together they could completely demolish archer and gilgamesh. Starkiller has above master level with both the light and dark sides of the force. He can pull starships out of the sky with ease. Kratos casually fought the likes of hercules and in terms of strength bested him. I'd say the chains would have to catch him first since he has the boots of hermes and his own chains to deflect along with the fact that he fought on par with and murdered zeus who was a teleporter that made sure to use it with actual lightening attacks.
