(on that note, I see in the text, for some reason it says Demo-Man was in 200x, which is another mistake)
Skeletor/Keldor was never married to Evil-Lyn in 200x. Nor have we ever heard there were plans of such.
In the cartoon they did have chemistry, as evident in episode "Price of Deceit". But MOTUC Bios do not "confirm" what happened
in that show. Or add, as far as I see it.
MOTUC Bios are their own canon. Using materials from multiple sources. So they are trying to
make their own story. Not "fill-in" anything to previous canons. There are too many inconsistencies to prove that.
From what I've seen; Only in MOTUC, have they been married and conceived a child. (please someone correct me, if I remember this wrong)
