Thanos (Marvel)

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?

1. Megatron (Transformers)

2. Frieza (Dragon Ball)

3. Madara Uchiha (Naruto)

4. Yhwach (Bleach)

5. Shao Kahn (Mortal Kombat)

6. M. Bison (Street Fighter)

7. Shredder (TMNT)

8. Heihachi Mishima (Tekken)

9. Thanos (Marvel)

10. Darkseid (DC)
