Surtur Vs. DoomsDay.

Round 1: Surtur When He First Appeared.

Round 2: Surtur When He Destroyed Asgard.

1. Probably Doomsday. Though we don't know what effect magic has on DD so it's speculation.

2. Planet Busting Surtur annihilates DD.

1) DD easily.

2) Surtur easily.

That was easy.

1. DD
2. Surtur

isnt DD durable enough to withstand those blasts from surtur? i mean the only thing that harm him was k'nite

Best Doomsday ever tanked was a nuke. Surtur destroyed Asgard by stabbing it.

1)DD
2) Surtur
