alan scott full starheart at his height could potentially solo quite easily. Sodom Yat from what point in time. Future Sodom who knew what the hell he was doing or newbie Yat who fights like superman w/ the occasional lantern blast.
Scenario 1. unless this is pc daxamites zeus takes this handily.
Scenario 2. Aforementioned issue applies. Define the context from which you want to pull them. New 52 Zeus wins hands down. Pre-Reboot normal 52. I'll hand it to zeus. Sodom needs more experience before I'd say he's anywhere close to putting up a serious fight. Alan would need to be full on starheart or pretty damn close to win majority IMO. Then again I have a pretty high opinion of the starheart so there might be some bias in there.
