Iron Man (Tony Stark): zodiac sign and birth chart
Tony Stark is a Gemini, born on May 29, 1970. That explains the mouth: the Sun and Mars both in Gemini, a man who talks faster than anyone in the room and builds his way out of trouble with whatever is lying around, a cave and a box of scraps included.

NEBO's take
Canon says Gemini. His personality says Leo.
We ran Tony through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as a showman first: the guy who lands on his own Expo stage with backup dancers.
Canon
Gemini SunMay 29, 1970, from Marvel's MCU guidebookNEBO's take
Leo SunRead from his personality- Sun
CanonGeminiNEBO's takeLeo
Canon's Gemini is the fast talker who never reads the script. Leo is the showman: Iron Man 2 opens with him dropping onto the Stark Expo stage, dancers and all.
- Moon
CanonPiscesNEBO's takeGemini
Canon's Pisces Moon soaks everything up, then the panic attacks hit. Our Gemini Moon copes by staying busy: the sleepless nights in Iron Man 3 turn into a whole garage of new suits.
- Rising
CanonNo birth timeNEBO's takeLeo
No birth time in canon. First impression in Iron Man: drink in hand in an army Humvee, cracking jokes and posing for a photo with the soldiers.
- Mercury
CanonTaurusNEBO's takeVirgo
Canon's Taurus thinks with his hands. Our Virgo reads everything overnight: asked when he became an expert in thermonuclear astrophysics, he says "Last night."
- Venus
CanonCancerNEBO's takeLibra
Cancer is the soft side he hides, the one that worries about his people. Libra is the Malibu charm that wins over the reporter who came to grill him.
- Mars
CanonGeminiNEBO's takeGemini
Same sign on both sides. Gemini Mars fights with words and inventions: "Genius, billionaire, playboy, philanthropist," fired straight at Captain America.
Where we agree: Mars in Gemini on both sides. Tony fights with his mouth first and his gadgets a second later.
How he shows up
Why he's like this
Gemini is the sign of quick talk, quick hands and ten ideas at once. Tony hits every one of them, in scenes fans quote word for word.
CoreGemini Sun
Drops the script
His team hands him a cover story on cards for the press. He reads a line or two, puts the cards down and says "I am Iron Man."
Iron Man (2008)
CoreGemini Sun
Wins the argument with a joke
A Senate hearing wants his suit for the army. He tells them he has "successfully privatized world peace" and the room can't get a word back.
Iron Man 2
In a fightMars in Gemini
Builds his way out
Held captive in a cave, he's told to build a missile. He builds the first Iron Man suit from scrap instead and walks out in it.
Iron Man (2008)
MindMercury in Taurus
Thinks with his hands
His father left a clue in an old Expo model. Tony tears up his own house to build a particle accelerator and makes a brand-new element at home.
Iron Man 2
LoveVenus in Cancer
Cares like a worried parent
He gives Peter Parker a new suit, then locks half of it behind a "Training Wheels Protocol" and a "Baby Monitor Protocol" so he can keep an eye on the kid.
Spider-Man: Homecoming
FeelingsPisces Moon
Feels it all, after
After the Battle of New York he can't sleep and gets panic attacks whenever someone brings it up. The joker carries more than he shows.
