Superman vs War of Realms

Can Superman end war of the realms armies and malekith all by himself?

Cis off, Superman is allowed to approach the sun during battle

Easily.

Punisher with unlimited ammo could have solo'd, ffs.

He would have trouble with the end game. Malekith became a Gorr level threat.

Superman would solo from a distance as he's chilling in the Watchtower.
