Gladiator should take this, I have NO clue what strength class you have to be to 'rend stars in two', but it has to be a damn sight higher then '4X Thor'.
Needless to say however that (if things begin to get a little hectic) Kallark COULD just throw Kurse into the sun, after all , this match is essentially Hammer-less Thor versus a no magic weakness Superman.
Edit : I've only just noticed how Glads name is a pun on Kal and Clark (Phonetically and Spelling wise) How stupid am I ?
If Thor can whoop on Gladiator when pissed off, then imagine someone 4x as strong physically beating on Glads. That my friend is what Kurse can and will do in this fight. Gladiator would not be aware of Kurse's iron weakness, and therefore would likely get beaten to death due to Kurse's immense strength and durability.
