Velma from Scooby Doo
Wearing a hideous orange sweater and having a short, manly haircut does not make Velma a lesbian. Being both bookishly nerdy and strong enough to carry her stoner friends and their dog while running away from ghosts does not make Velma a lesbian.
Even Velma's inspiration (the character was allegedly based on Zelda from the CBS sitcom The Many Loves of Dobie Gillis, and Zelda was played by proud homosexual Sheila Kuehl) doesn't make her a lesbian. While all of these facts do provide strong supporting details, they're not what really pushed us over the fence on this issue. It was totally Daphne.
Let's just try to figure out why Velma was even part of this gang: Her life was always in danger, and she was clearly smarter than the rest of the group. Could she have stuck around because of a crush on one of the guys? Well, Shaggy and Scooby are spineless losers and Fred, though certainly talkative and well dressed, is patently useless and, we don't think it's going too far to say, blandly asexual.
So, what kept Velma coming back to a group that, in addition to being intellectually beneath her, was apparently a magnet for creepy old men dressed as monsters? The same thing that kept horny boys tuning in all those years: Motherfucking Daphne. Velma was simply no match for Daphne's overpowering sexual magnetism.
Daphne had everything: a killer body, long, red hair and that purple headband. You bet your ass she was raising more than the dead on that haunted island (ka-pow!), and Velma's heartbreaking, unrequited love could be the only explanation for her continued involvement with the ol' gang.
