Sorry, you don't often think of villains as having relations.

Oops and forgot
Namor<Widow>Marrina

Absorbing Man married Titania.

The original Guardian is Roy's uncle, not father. And the Guardian we have in Clix isn't that Guardian - he has no relation to Roy.

And I don't see Connor anywhere on your list. He's a clone of Superman & Lex Luthor, so you have links there. Lex sees him as a son, Clark sees him as a brother. Connor has the Kent last name, is currently living with Jonathan & Martha and calls them Uncle & Aunt.

I know, I had totaly forgotten it.

Also to add to Siblings
Lorelei~Enchantress (Marvel)

Justin Hammer
-Crimson Cowl (Justine Hammer)

S'OK. I thought you had missed my first post. Thanks for including it on the list.

Also under Siblings
Blockbuster (R)~Blockbuster (EV)

And
Brainiac
-?Brainiac 5

Not sure how many genreations it would be.

Wasn't Kraven and Calypso Married?

And should we count Carnage as Venom's son?

And before you bring up Wonder Woman (Hypolyta), Wonder Woman (Diana) and Donna Troy. Check out the wierd Hall Family mish-mash that is on Whoclix

Isn't the CD Captain Boomerang a half brother to Impulse/Kid Flash? I don't read Flash, but a friend mentioned it to me.

Heres one I would never have thought of
Count Nefaria
-Madam Masque

He is, so

Kid Flash/Impulse~1/2~Captain Boomerang
