Well, that's only skins examples and only the first has some relevancy about the realities differences (the two others being from really different world while the first is/was a future of Earth-616.

But that's the thing: Multiverse makes everything unsure, and that wikia is filled with page full of copy-past without exact, stated, referenced material: If you find an issue/episode showing characteristics of the characters, add those and add the ref in a ChartRef (I think it's that) field, if you don't know how it is, check major characters pages who will certainly have that in the template.
