Hephaestus, a.k.a. Vulcan, a.k.a. the god of the forge, is basically the nerd god. He’s the quiet, introverted one that spends most of his time in his garage, alone, playing with his toys, building machines and armor and jewelry. He believes in reason over all (there’s a reason Spock’s people are named after him). He’s overshadowed by his jock brother Ares, god of war. Notably, he’s the only Greek god who’s unattractive.
Often the myths present Hephaestus as an innocent victim who has done nothing to earn his ill treatment. But Hephaestus is also a classic “nice guy”: a self-centered, entitled, bitter schmuck who thinks he’s smarter than everyone else and then doesn’t understand why people don’t want his advice (see also: Nice Guys of OKCupid). The kind of guy who can’t understand why girls prefer “handsome jerks” like his brother to “nice guys” like him. Hephaestus, while demonstrating the good sides of being a nerd (he’s super good at making shit), also demonstrates a lot of nerdom’s fatal flaws.
