Gamora is supposedly the adopted daughter of Thanos, unless my limited GotG info is wrong.

Kang the Conqueror is Nathaniel Richards, son of Reed and Sue Richards, again unless my info/memory is off.

Those I had in there already.

i did not see them said and did not feel like going through an entire thread to see what had been said

Didn't John Stewart (Green Lantern) married Hawk Girl and even had a son? Or was that just in the animated movie?

Also, Superman and Wonder Woman were a couple in Kingdom Come.

Did not finish post 1 before you tired out?
