Dracula
Stoker's creation has fundamentally shaped Western horror. The Count appears in the Guinness World Records as cinema's most frequently portrayed literary character, with actors from Bela Lugosi to Gary Oldman donning the cape. Dracula established vampire conventions that persist today: the aversion to garlic, the mirror absence, the stake through the heart. His influence extends into linguistics itself, with 'Dracula' becoming synonymous with vampirism worldwide, generating an estimated $10 billion in cumulative merchandise and adaptations.
Sonic
The blue hedgehog achieved what few video game characters manage: genuine mainstream penetration. With over 1.5 billion game units sold across the franchise, Sonic rivalled Mario for console supremacy throughout the 1990s. His 2020 film grossed $319 million worldwide, spawning a franchise that continues expanding. Sonic's influence on gaming culture, speedrunning communities, and internet meme generation has proven substantial, though geographically concentrated in Western and Japanese markets.
