I don't get how you don't get what I'm saying. Doing it in another scan is fine. That's proof positive I didn't need. I was saying the scan presented, of 2 Supermen destroying a world can't be used to say 1 Superman can destroy the world. It's a shared feat so a single person can't claim it.
Posting a scan of 1 Superman destroying a world is fine. Since it's just him, because of that scan you can say "Yeah, Superman can do it in one punch."
But you can't say "Yeah, Superman can do it in one punch." And then post a scan of 2 Supermen going at it.
That's the only point I've been making.
