Actualy, thebigZZZZ had corrected me on this and it was what I had meant. It should have been
Digger Harkness + Meloni Thawne = Owen Mercer

Okay, I don't want to de-rail the thread, so could someone PM me the whole sorted mess here, because I'm just getting more confused here. 20th Century, 25th Century, 30th Century...

Here are the entries for Captain Boomerang and Bart Allen on the rightm you can see "Notable Relatives" and will see the mothers name on both and listing each other as half brothers

Okay, after reading that I may be more confused.

According to this page, Jessica Drew may be Viprs daughter

Morgan Le Fay
-?Black Knight

That's why I like DC, because Marvel fans blather on about pre-Crisis DC universe like it was still there!

Oh, and to ad confusion to the Captain Boomerang/Kid Flash familiy. The original Professor Zoom (Eobard Thawne) is a decendanct of the mother. I think the Prof Zoom we have it Zoom 2 (Hunter Zolomon) though.

Aw heck. We're going to let him be the Original Zoom

His outfit is Zoom 2, but his name and dial is Zoom 1. So.

Not sure how off this is

This is as close as I could figure to do with the Hall family

say any relations among superwoman, owlman, and ultraman? can't remember exactly...one of them is superwoman's lover right?

IIRC Ultraman & Superwoman are married, but she's having an affair with Owlman.

Since someone mentioned Brainiac I figured I'd put in what I (think) I know about it. Originally he was Brainiac 13 (HT), who was destroyed and had all of his parts melted down. Eventually he was rebuilt and became Brainiac (Icons). Brainiac 5 (Unleashed) is yet another model of the same cyborg, but from the Legion's alternate future timeline, and is a hero. And let's not forget his pet monkey, whose name escapes me at the moment.

If any of this is wrong, I apologize, it's been forever since I've had anything to do with superman villains. Please correct if I'm mistaken.
