Roy Mustang: zodiac sign and birth chart
Roy Mustang has no canon birthday. Neither the manga nor Brotherhood gives one. Read from his personality, he's a Leo: the Flame Alchemist who plays the lazy charmer in public and the long game in private, with his eye on the top seat. Aries Moon and rising are the speed and the temper, Leo Mercury sells the dream and Cancer Venus is the loyalty to his people.

NEBO's take
No birthday in canon. His personality says Leo.
We ran Roy 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 fire all the way down: ambition that starts fast, and then actually finishes.
Canon
No canon birthdayNever given in the manga or animeNEBO's take
Leo SunRead from his personality- Sun
CanonNot in canonNEBO's takeLeo
Leo wants the throne and plays the part. Roy decides to become Führer and spends years walking toward it, with a smile on and a plan behind it.
- Moon
CanonNot in canonNEBO's takeAries
An Aries Moon feels hard and fast. His anger is quick, and it takes someone steady beside him to keep it from becoming the whole man.
- Rising
CanonNo birth timeNEBO's takeAries
No birth time in canon. First impression: the slacker who dozes at his desk and jokes about shorter skirts, while Lieutenant Hawkeye watches him with a look.
- Mercury
CanonNot in canonNEBO's takeLeo
Leo talks like it's a stage. Roy sells his team a dream and they follow.
- Venus

Cancer loves like family. His people are his, and Lieutenant Hawkeye has sworn to shoot him if he ever goes wrong.
- Mars
CanonNot in canonNEBO's takeLibra
Libra fights with precision. His flame lands exactly where he is looking, never wider than it has to be.
What canon does give: a colonel who aims for the top of the country and keeps a team that would follow him anywhere. Leo sets the goal, Cancer holds the team together.
How he shows up

First impressionAries rising
The lazy charmer
To most people he's the colonel who naps, flirts and jokes about shorter skirts in the military. It's the cover for a man playing a long game.

A team that would follow him
Riza Hawkeye, Havoc, Breda, Falman and Fuery stay by his side. Hawkeye has sworn to shoot him if he ever strays from the path.
