Here are my 'Fantastic Man Family" villains. More to come on these. The villains for this usually change as I learn more about Marvel villains, but I've been doing this for about 23 years now, so I should probably start wrapping it up :
37. Lex Luthor + Dr. Doom = Dexter Doom, AKA "Dr. Dome"
* Main villain for each team, and arguably the BIG bad for both universes.
38. Lex Luthor II + Kristoff Vernard = Dexter Doom, Jr.
* Offspring of the above.
39. Contessa + Lucia Von Bardas = Contessa Doom
* Ex-wife of the main villain.
40. Brainiac + Psycho-Man = Psycotiac
* Due to the Kandor/Microverse thing.

* Due to the Phantom Zone/Negative Zone thing.
