Grover Underwood: zodiac sign and birth chart
Grover Underwood 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 Moon and rising in Cancer too: the soft-hearted friend who feels everything and shows up anyway. The satyr who shakes like a leaf and still never leaves a friend behind is Cancer in action.

NEBO's take
No birthday in canon. His personality says Cancer.
We ran Grover 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: sensitive, loyal and quick to worry about the people he loves.

Cancer looks after its own. Grover poses as Percy's school friend on crutches while quietly guarding him.
- Moon

Cancer Moon feels other people's feelings. He and Percy share an empathy link, so each knows when the other is in trouble.

No birth time in canon. First impression: a nervous kid on crutches with a wispy beard, a big heart and a worried face.

- Venus
CanonNot in canonNEBO's takeVirgo
Virgo Venus loves in small, practical ways. Grover's idea of a treat is an enchilada or a tin can.
- Mars
CanonNot in canonNEBO's takePisces
Pisces Mars is scared and goes anyway. He shakes like a leaf, but he doesn't leave a friend behind.
What canon does give: a satyr who is scared of nearly everything and brave about the one thing that matters. A Cancer answer is to protect your people and cry about it later.
