I wouldnt say he was as powerful as Galactus. Thats just an assumption by quite a lot of peeps on these forums and i dont know why. He was somewhere in between current Thanos and the cube beings. Still very powerful. Galactus at least could hold his own against Phoenix for a minute or so before getting rocked, DS got punked from the start.
Odin and Zeus as high level skyfathers are above current thanos easily, but just below the cubes. Thanos has fought odin before and got dealt with. Both of them together would rock Thanos and Pre C Darkseid.
But I doubt it will be the Darkseid everybody is used to. And by 'shine' I also don't mean beating up Superman/The Justice League or such. It will be on a much complex level
