Iron Man
A self-fulfilling prophecy where a man turned to steel by a magnetic field causes the apocalypse he tried to prevent.
"Iron Man" is a song by the English heavy metal band Black Sabbath, released in 1970 from their second studio album, Paranoid. The lyrics, composed by bassist and lyricist Geezer Butler, narrate a self-fulfilling prophecy where a man travels to the future, witnesses an apocalypse, and returns to warn humanity. En route, a magnetic field turns him into steel; ridiculed and ignored by those he sought to save, he resents them and ultimately causes the very disaster he foresaw. Butler has explicitly stated there is no link to the Marvel Comics superhero, noting he never read American comics as a child. Instead, he drew inspiration from Ozzy Osbourne's "iron bloke" remark, H.G. Wells novels, Hammer horror films, and his own childhood supernatural experiences. Raised in a devout Catholic family, Butler has stated the song is not an allegory for Jesus Christ; he described it as a story about a man who becomes a monster due to rejection.

Verified Timeline
Lore & Background
The narrative centers on a traveler who witnesses the end of the world and attempts to return to his own time to warn humanity. However, during his journey back, a magnetic field transforms him into steel. Upon returning, he is ridiculed and ignored by the people he intended to save. Feeling deep resentment from this rejection, Iron Man retaliates by actually causing the apocalypse he had originally seen in his vision. This story is not an allegory for Jesus Christ; Butler has described it as a tale of a man who becomes a monster due to rejection. Butler's inspiration was shaped not only by literature like H.G. Wells' novels but also by Hammer horror films from the 1960s, magazines such as Man, Myth and Magic, and his own childhood supernatural experiences and dreams that came true.
In Their Own Story
While recording the track, producer Rodger Bain and studio engineer Tom Allom faced tremendous difficulty capturing the "power and depth of the sound" of Bill Ward's bass drum due to microphone limitations of the era. The resulting composition tells a grim tale where a man becomes a steel figure after a magnetic field transforms him. Clad in metal, he is mocked by the very people he tried to save from the future catastrophe he witnessed. Driven by resentment over this ridicule and ignorance, the Iron Man figure fulfills his own vision by bringing about the apocalypse. This tragic arc was conceived by Geezer Butler as a science fiction story inspired by Ozzy Osbourne's "iron bloke" remark, blending supernatural elements drawn from his childhood dreams with themes of vengeance rather than redemption.
