Loki's smarter than the both of them. Surtur loses to either one, but Loki using his magic...I say Zod and Doomsday can beat him in a struggle.

General Zod and Doomsday would win. Loki is smarter but in the easy battle, Surtur would get kill by Doomsday. In the long hard struggle battle, Loki would be defeated and wounded by Doomsday and General Zod.

Trump takes them all out.

I agree...of course I may be biased
