Given all the alternate timelines, What Ifs, Else Worlds, reboots, etc that have come and gone, their current power levels, and how they're portrayed in their universes....
How powerful do you see them being in a thousand years, each in a best case scenario?
which character do you see as being more powerful in a thousand years (their time)?
Would these versions change your opinion on a battle winner, or would your opinion stay the same as current versions?
I don't think he'd be entirely the same though. When we find out how H'el gained his new powers (by flying close to black holes, different colored suns etc). The same could easily happen to Superman. I mean in a thousand years he will do a lot of travelling which could see him gaining different powers.
Not that I am making a statement on who would win between the the 2 characters 1000 years on though.
Exactly. Also, in the Batman Beyond continuity, Superman is far from weak, but he is not as strong as he was when he was younger. This IMO would all depend on which reality the Superman is from. Thor on the other hand becomes a beast, and is able to go at it with Galactus on a physical level (If old man Thor is actually the future of his 616 self). It's certain that some future Supermen would most likely win with ease, while others would be trashed.
