No birthday in canon. Its personality says Libra.

Libra knows which face to wear. Kaiju No. 9 passes itself off as a human, and it does so without any of the warmth.

- Rising

No birth time in canon. First impression, Sagittarius style: confident and direct, a kaiju that acts as if the whole battlefield is its to roam.
- Mercury

Libra Mercury is smooth and persuasive. It makes long-term plans and always stays a step ahead of the Defense Force.
- Venus CanonNot in canonNEBO's takeNo clear pick
- Mars
CanonNot in canonNEBO's takeLibra
Libra Mars fights with what is already in the room. It soaks up the powers of others and turns them against its enemies.
What canon does give: a monster that thinks. A Libra answer is to weigh the room, take what is useful and use it against the other side.
