Mickey Mouse and Sonic The Hedgehog, two of fiction's most famous anthropomorphic characters and the mascot of Disney and Sega. But before those two, their respective companies previously had another mascot, being these two. Despite being replaced, however, these two still have made major appearances in more modern tie-ins (Oswald appearing in the Epic Mickey games and Alex Kidd with his new game that released last year), so it's not like they're completely gone.
