Otto Hightower: zodiac sign and birth chart
Otto Hightower has no canon birthday. The show doesn't give one, and neither does Fire & Blood. Read from his personality, he's an Aquarius, Sun and Moon both: the cold-headed Hand who plays the long game and rarely raises his voice. He keeps the files and he keeps the family pride.

SourceNo canon birthday: the HBO series gives Otto no date, and George R.R. Martin's Fire & Blood gives years at most. The chart is NEBO's take, read from personality.

NEBO's take
No birthday in canon. His personality says Aquarius.
We ran Otto 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 first: detached, strategic and always three moves ahead of the room.

Aquarius thinks in systems. Otto criticizes Daemon's brutality as City Watch commander, and frames it as a problem of order.
- Moon
CanonNot in canonNEBO's takeAquarius
An Aquarius Moon keeps feelings at arm's length. Otto manages the room instead of talking about how he feels, even when the king overrules him.

CanonNo birth timeNEBO's takeTaurus
No birth time in canon. First impression: stone-faced and steady. Dismissed as Hand, he leaves quietly and he's back when the king needs him.

CanonNot in canonNEBO's takeGemini
Gemini Mars plays two angles at once: a polite offer in one hand and leverage in the other.
What canon does give: a Hand to the king who works for years toward one result, his own blood on the throne. An Aquarius answer is to treat it like a system that can be solved.
How he shows up
Why he's like this
Aquarius is the sign of cool thinking, long plans and standing apart from the room. Otto hits every one of them, in scenes fans know by heart.
CoreAquarius Sun
Order over temper
Otto tells the king that Daemon is too brutal as commander of the City Watch, and that the city shouldn't be run by fear.
Season 1, episode 1
First impressionTaurus rising
Dismissed, unmoved
The king strips him of the Hand's chain. Otto leaves without a scene, and returns to the post later when Viserys needs him.
Season 1, episodes 4 and 7
FeelingsAquarius Moon
Keeps the news close
When the king dies, Otto hides it, closes the doors and calls the council before the other side knows anything.

What zodiac sign is Otto?
Canon never says. Neither the show nor Fire & Blood gives Otto a birthday. By personality, NEBO's take is Aquarius.
When is Otto's birthday?
It isn't given anywhere in the show. Fire & Blood, the book behind it, gives years at most, never a day or month.

By personality, yes. Detached, strategic and always planning ahead, which is Aquarius behavior. It's NEBO's take, not canon, because the show never gives him a birthday.
What element is Otto?
Air. Aquarius is an air sign, and 3 of his 4 placements are air too.
Who is Otto most compatible with?
By chart, Baela Targaryen, Corlys Velaryon and Aegon II. Aquarius Moon and Aries Moon: they know how to settle each other down.
