If I was picking non-game characters, the top 3 would be Goku (because memes), James Bond (because Goldeneye Multiplayer is a staple of N64 fans childhoods, and Scrooge McDuck (protagonist of the only licensed NES game that’s considered enough of a classic that it got a spiritual successor). Beyond that, next up would be Popeye (without whom we’d never have Mario), Doraemon (the only non-game character to rank on Sakurai’s mail-in Smash 64 ballot), and Turok (because the N64 has so few new IPs, it’s remembered as a cult classic, and everyone remembers it more for the game then the comics).
