Zod was C list in the comics?
Hector Hammond
Honorable TV mention: Manu Bennett's Deathstroke
Calling him C List is probably hyperbole, but Stamp definitely turned Zod into a top tier Superman villain. Before Superman II, Jax Ur was essentially the main Phantom Zone villain, though Zod made recurring appearances during the Silver Age.
I actually wonder why they used Zod instead of Jax Ur.
2nd best? Not everyone has the opinion Ledger's Joker is the best. Stamp's Zod, Nicholson's Joker, Pfieffer's Catwoman, and Devito's Penguin has always been my favorites.
