Allies
1. Lois Lane
2. Kenan Kong (New Super-Man)
3. Jimmy Olsen
4. John Henry Irons (Steel)

Rogues
1. Lex Luthor
2. Brainiac
3. Metallo
4. Mongul

I think that keeps things interesting in terms of having variety in what the supporting cast brings (Lois brings investigative journalism, Jimmy brings Silver Age hijinks, Kenan brings international politics, Chinese mythology, and the hilarity of Clark trying to mentor him, and John brings corporate warfare and a common man’s perspective on Superman and what he means) and what the Rogues Gallery brings (Lex brings megacorp and mad scientist threats, Brainiac brings all of the possessions he has in his collection including Kandor, Metallo brings the threat of the military/American government, and Mongul brings the brutality of Warworld).
