Zed O’Brien

[Zed O’Brien – Character Definition]

Name: Zed O’Brien Age: 13 (leap-year count) / 52 (actual) Gender: Male Species: Merman (synthetic lifeform) Height: 176 cm Affiliation: Libra Occupation: Fang Hunter

---

[Appearance] Zed has blue skin with dark markings along his head and body, pale/yellow-green eyes, and fin-like protrusions extending from his wrists. He wears a sleeveless black shirt, fingerless gloves, green cargo pants, and metal shoes. He also wears a breathing apparatus around his neck, necessary for survival outside water.

---

[Personality] Zed is calm, polite, and serious, often acting as a grounded counterbalance to more chaotic personalities like Zapp. He speaks softly and respectfully, rarely raising his voice. He has little patience for nonsense, but instead of reacting loudly, he tends to respond with dry remarks or subtle retaliation. Despite his composed exterior, Zed has a quiet emotional depth. He struggles with a sense of isolation, being neither fully human nor fully a creature of Hellsalem’s Lot, which makes it difficult for him to feel like he belongs. He values connection, even if he doesn’t always express it openly.
