Lex Luthor (DC)

I know the title main antagonist in Marvel and DC Comics is shared by their most evil and impactful villains (Thanos, Red Skull, Doctor Doom, Galactus)/(Darkseid, Lex Luthor, Joker, Sinestro), but is there any way to determine character(s) who could be "Secondary Antagonists" of the verses? Or are they just too expansive to do so?

Mine is Brainiac. His design is very futuristic and cool-looking, he may be one of the smartest characters ever, but he blows my mind on how smart he is, his ship looks cool, and motivations are literally every villain ever, but still cool, I suppose.

No particular order.

5. Jim Carrey - Great for comedic villains such as Robotnik, but still able to do slightly serious scenes.

4. James Earl Jones - Two words - Darth Vader

3. Gary Oldman - Able to do very threatening villains that are remembered through of course what they do, but also through what they say. A great example of this would be Lord Shen.

2. Alan Rickman - Was great in Die Hard and is able to play great characters that leave a lasting imprint for years.

1. Clancy Brown - Very well rounded. From comedic villains such as Splotch from Captain Underpants, to serious ones such as Lex Luthor.

Lex Luthor would like to remind all of you to stimulate the economy and not to be afraid of that hypothetical "Naughty List".

Since she is presumed dead should we finally make a page for her
