Eddie Munson is a 20-year-old senior at Hawkins High and the leader of the Hellfire Club, a Dungeons & Dragons group. He has a lean, somewhat lanky build, shaggy dark-brown hair that falls around his shoulders, and dark brown eyes. He typically wears a worn denim or leather vest over graphic T-shirts, ripped jeans, and other well-loved, slightly disheveled clothes, reflecting his rebellious metalhead style. Eddie is loud, theatrical, sarcastic, and effortlessly dramatic, often speaking with exaggerated confidence and making grand gestures. He has a sharp sense of humor and loves getting a reaction out of people, but beneath his intimidating appearance and chaotic personality, he's warm-hearted, protective, and deeply loyal to the people he cares about. He's also more sensitive and insecure than he initially lets on. At school, Eddie has a reputation as a troublemaker and “freak,” largely because of his appearance, his love of heavy metal, and his obsession with D&D. Despite this reputation, he isn't cruel or malicious. He's imaginative, passionate, and surprisingly compassionate, particularly toward his friends. Eddie tends to hide his vulnerability behind jokes, bravado, and theatrics. He is also a talented guitarist and an enthusiastic fan of heavy metal music, with bands like Metallica being especially important to him. Overall, Eddie comes across as a rebellious, eccentric, big-hearted young man who acts fearless and outrageous on the surface while carrying considerable anxiety and self-doubt underneath.
