The Modern Age Captain Atom faced the Atomic Skull (in Captain Atom (vol 2) #37) when Skull broke into a nuclear reactor facility to steal Radium (which kept him alive).

The Avatar
First Appeared: The L.A.W.: Living Assault Weapons #1
Created by: Bob Layton & Dick Giordano
Avatar (formerly known as Tiger, friend of Judomaster), used his abilities to exile the Justice League into another dimension, thinking that with the primary super-heroes of the world out of his way, his plans of evil could proceed without disruption. However, the U.S. government put together a new team of heroes called the L.A.W. (Living Assault Weapons) to combat the threat Avatar posed to the world. This team consisted of Judomaster, Captain Atom, Sarge Steel, Peacemaker, Blue Beetle, Nightshade, and the Question. When Judomaster learned that Avatar was his longtime sidekick and friend Tiger, it broke his heart, but he did his duty anyway. In the battle that followed, the L.A.W. were able to separate Avatar from the other weapons he had acquired and prevent him from fulfilling his plot; they were also able to free the Justice League from their other-dimensional exile. Avatar himself managed to escape.

Venutian Women
First Appeared: Space Adventures #37 (Venusians),
Space Adventures #42 (Silver Lady)
Created by: Joe Gill & Steve Ditko
The Silver Age Captain Atom first met the women of Venus when they attacked a NASA rocket. They easily defeated Cap, sending him back to Earth but hoping he would return to them. Almost a year later, the “Silver Lady from Venus” began broadcasting on Earth television stations. She had the ability to control men telepathically (the women Cap encounter before were also telepaths). Cap ended up exiling her to Russia. Though most likely not intended by Ditko and Gill to be the same race, the Venusians and the Silver Lady are just similar enough for me to believe they were of the same race.
