Ask Google about King Diamond and you’ll get the Satanism headline in half a second. That’s not wrong, exactly — it’s just not the story that explains why he’s still one of the most fascinating figures in metal 40 years in. The real answer is in the stories that never make the quick summary: a near-lawsuit from Gene Simmons, five hours legally dead on an operating table, and a haunted apartment that shaped his earliest music. Here are King Diamond’s wildest stories, the ones that actually get at the legend.
The 13 Stories That Actually Explain The Legend
1. Gene Simmons Almost Sued Him Over Face Paint. In the early ’80s, KISS bassist Gene Simmons reportedly threatened legal action, claiming King Diamond’s face paint copied his own. King’s response has become one of the great deadpan lines in metal history: he told Simmons he didn’t have much money to sue him for, but plenty of other people had money Simmons could be sued by. The suit never materialized, and King eventually evolved his design into the more elaborate “cross” style fans know today anyway — influenced, he’s said, by Peter Gabriel and Alice Cooper, not Simmons at all.
2. He Was Legally Dead For Five Hours. On November 29, 2010, after years of heavy smoking led to multiple heart attacks, King underwent emergency triple-bypass surgery. His heart was stopped for a staggering five hours. He’s since described waking up with a breathing tube and having to relearn how to breathe and walk as a “nightmare come to life” — an experience that directly shaped the medical horror themes running through his long-awaited Saint Lucifer’s Hospital 1920 trilogy.

3. He Lived In A Genuinely Haunted Apartment. During his early Mercyful Fate days, King lived in a Copenhagen apartment he’s said was plagued by real poltergeist activity. His fascination with the supernatural isn’t just old horror movies — some of it is lived experience, which explains the authenticity running through even his earliest, rawest material.
4. He Guest-Starred On Metalocalypse. Proving the horror persona comes with a real sense of humor, King voiced multiple characters across four episodes of the animated series, including the Blues Devil and a cynical fast-food manager, plus a cameo as one of Dethklok’s faceless Klokateers.
5. He’s A Playable Character In Guitar Hero. To unlock him in the 2009 game, players had to master Mercyful Fate’s “Evil.” Developers meticulously recreated his stage movements and iconic bone-cross mic stand — though his makeup got a slight tweak, for the same licensing sensitivities that almost got him sued in the first place.

6. Metallica Bring Him Onstage To Perform Their Own Tribute To Him. After recording an 11-minute Mercyful Fate medley for Garage Inc., Metallica have repeatedly invited King onstage to perform it with them, including a 30th-anniversary show in San Francisco — proof of how deep the King/Metallica mutual admiration actually runs.
7. He Had A Cordial, Viral Moment With Stryper’s Michael Sweet. In 2022, a clip of King and the Christian metal frontman sharing a respectful, cordial exchange went viral despite their polar-opposite worldviews. Sweet later said he’d be open to a collaboration — though he’d “pray about it” first.

8. His Album “The Eye” Is Based On Real History. Not every King Diamond concept is ghosts and hauntings — 1990’s “The Eye” draws from the French Inquisition and the real case of Father Urbain Grandier, exploring religious hypocrisy and actual witchcraft trials. It remains one of his most intellectually ambitious records.
9. He Runs His Career Like A Family Business. King and his wife, Livia Zita, manage his career together with unusual independence for an artist at his level. Livia isn’t just a partner — she’s a backup vocalist on records like “The Puppet Master” and has been central to remastering his back catalog.
10. His First Two Album Purchases Still Define His Sound. King has cited Deep Purple’s “Fireball” and Black Sabbath’s “Master of Reality” as the first two records he ever bought — and the rhythmic drive of Iommi and operatic flair of Ian Gillan are still audible in every King Diamond and Mercyful Fate track since.

11. His Influences Run Deeper Than Metal. Beyond Sabbath and Deep Purple, King’s vocal style draws on the theatricality of Alice Cooper and Arthur Brown, the progressive structures of Peter Gabriel, and the soaring range of Uriah Heep’s David Byron — a mix of prog complexity and metal grit that’s shaped his sound since day one.
12. His Solo Debut Wasn’t Actually A Full Concept Album. Despite being known for epic, album-length horror narratives, King’s 1986 solo debut “Fatal Portrait” was a transition piece — only the first five songs follow a continuous ghost-story arc, while the rest, including the holiday favorite “Halloween,” stand alone. It was the stepping stone to the full concept storytelling of “Abigail.”
13. His Satanism Is A Philosophy, Not A Religion. The most consistently misunderstood King Diamond fact: he’s an avowed LaVeyan Satanist, made an eternal member of the Church of Satan by Anton LaVey himself in 1988 — but as he’s clarified for over 40 years, it’s a commitment to individualism and self-empowerment, not the worship of a literal devil. It’s the philosophical backbone running underneath every concept album he’s written.
