The Joker
The Joker fundamentally redefined comic book villainy upon his 1940 debut and continues shaping the form today. Before the Joker, villains sought wealth or power; he introduced the concept of chaos as motivation. His influence permeates modern antagonists from Heath Ledger's Dark Knight interpretation inspiring countless morally ambiguous villains to the character study approach of Joaquin Phoenix's Joker influencing prestige comic adaptations. He proved that comic book films could be serious art, not merely entertainment.
Wolverine
Wolverine's 1974 emergence pioneered the anti-hero archetype that would dominate comics through the 1990s and beyond. His moral ambiguity, violent methods, and tragic backstory created the template for characters from Cable to Deadpool to Punisher's modern interpretations. The Logan film demonstrated that superhero narratives could achieve genuine dramatic weight, earning serious awards consideration. His influence extends beyond comics into gaming, where his archetype defines countless playable characters.
