New Earth characters, for this site, come in three types: IMO we should be aiming for Superman (Clark Kent) as the standard for the first appearances. But there are going to be glitches since Crisis was by no means a clean reboot. Ideally there would be a discussion on the article page to nail down a consensus in those cases and Notes added.
 * Characters created for the "main" DCU after Crisis and before Flashpoint. These are straightforward.
 * Characters that DC essentially kept the entire pre-Crisis history and ported it to New Earth. IIUC for ease of editing an Admin decision was made to just do one article for them. There is also the fact that the "old" version would replicate most of the "New" on.
 * Characters Like Superman where DC dumped chunks of pre-Crisis continuity. Because of that complexity we've got articles for the post-Crisis" (New Earth) version as well as some or all of the pre-Crisis'' versions. (And Legion character being a worse snarl).
