Poseidon: zodiac sign and birth chart
Poseidon has no canon birthday. Rick Riordan's books never give him one, so the chart is NEBO's take, read from his personality. Read that way, he's a Cancer with Cancer rising and Mercury: big feelings, few words, and a soft spot for his kids that shows up as a gift or a storm. The god of the sea in a Hawaiian shirt and a fishing hat is Cancer, shell and all.

NEBO's take
No birthday in canon. His personality says Cancer.
We ran Poseidon 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 water first: moody, protective and hard to read.

Cancer protects the family. When Zeus blames Poseidon's son for the stolen bolt, the sea god's side of the family is on the line.

Scorpio Moon feels deep and hides it. When his children are in danger, he becomes unshakable.
- Rising

No birth time in canon. First impression: a man in a Hawaiian shirt and a fishing hat, looking like a tourist on a boat.
- Mercury
CanonNot in canonNEBO's takeCancer
Cancer Mercury says little and means a lot. He is no talker, and his words to Percy are rare.
- Venus CanonNot in canonNEBO's takeNo clear pick
- Mars
CanonNot in canonNEBO's takeScorpio
Scorpio Mars is storm and force. He fights the undersea war against Oceanus and then helps Olympus.
What canon does give: a god who rarely visits and loves his kids all the same. A Cancer answer is to show love from a distance, and to guard it fiercely.
