I assume these ranks are in pure strength and not overall power level?
I aslo assume that the 99 is what we rabk current Supes at?
Cyborg Superman - 80
Zod-90
Doomsday- 85 (currently Supsles is quite a bit stronger than in DoS)
Darkseid - 150
Eradicator- 80-84
Rogol Zaar- no clue
Mongul- 85
Superboy Prime - 200
Parasite - obciously he can reach 99 one he absorbs but his base strength that he has at default (after absorbing strange visistor) is probably 80 ish
Braniac- some versions are 99 some 60 some in between
Metallo - 70, he does well vs Supes by weakening him
Amazo- not a superman enemy but a JLA one. Around 95 at base
Cyborg Superman - 99 (Supes admitted they are equals)
Zod- 99, he is Supermans equal
Doomsday- latest version, 150. Took both Diana and Supes to fight him and both almost died
Darkseid - 170
Eradicator- 110
Rogol Zaar- 150, he took on both Zod and Superman and was winning
Mongul- 90
Superboy Prime - 170
Parasite - base, 80.
Braniac- varies
Metallo - 60. Kryptonite is his advantage
Amazo- 150 and then grows from there
