The Flash (Barry Allen): zodiac sign and birth chart

Barry Allen has no fixed canon birthday. Two sources give two different dates, so nothing is settled. Read from his personality, he's a Gemini: the forensic scientist who talks fast, thinks faster and is late to everything anyway. Sun, Moon, rising, Mercury and Venus all sit in that one sign, and an Aries Mars is why he runs first and thinks after.

Birth chart

Barry's chart at a glance

No canon birthday, so this is NEBO's take, read from his character.

FlowingTense

Fire1
Earth0
Air5
Water0

Mostly air. 5 of his 6 placements are air signs.
Double Gemini. Sun and Moon in the same sign, about 1 in 12 people have that.
About 1 in 34 birthdays get Barry in the app's Superman world.
Other Geminis here: Jimmy Olsen, Cyborg (Victor Stone) and Iris West.

NEBO's take

No fixed birthday in canon. His personality says Gemini.

We ran Barry 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 air nearly all the way: fast thinker, fast talker and always three steps ahead of the room.

NEBO's take

Gemini SunRead from his personality

Sun CanonNot in canonNEBO's takeGemini
Gemini has two sides. Barry is a police forensic scientist first, and a bolt of lightning makes him the fastest man alive.
Moon CanonNot in canonNEBO's takeGemini
Gemini Moon can't sit still. He runs around the world and still arrives late for a date with Iris.
Rising CanonNo birth timeNEBO's takeGemini
No birth time in canon. First impression: a friendly talker who is already halfway out of the room.
Mercury CanonNot in canonNEBO's takeGemini
Gemini Mercury tests everything out loud. In the CW series he wakes after a coma and starts measuring his speed like an experiment.
Venus CanonNot in canonNEBO's takeGemini
Gemini Venus flirts with words. Barry is the hero with a quip ready even when the stakes are high.
Mars CanonNot in canonNEBO's takeAries
Aries Mars goes first and thinks later. In Flashpoint he runs back in time to save his mother and breaks the world.

What canon does give: a police scientist from Central City who gets hit by lightning and becomes the fastest man alive, and is always late. A Gemini answer is the lab brain, the quips and the one quirk nobody can fix.

How he shows up

Why he's like this

Gemini is the sign of speed, wit and a mind that never sits still. Barry hits every one of them, in stories fans know.
