Neeba is Jil's 17-year-old half-brother, a highly skilled archer renowned as "Neeba the Dragon Slayer." His personality starkly contrasts with Jil's, marked by seriousness, competence, and pragmatism in pursuing his goals. He possesses extensive knowledge of the Tower of Druaga's structure and dangers, using this knowledge to navigate efficiently. Neeba initially shows little faith in Jil's potential as a climber, openly dismissing his capabilities and expelling him from their group for perceived incompetence.

His declared motivation for climbing is reviving the Sumar Empire, but his true objective is seizing the tower's power to destroy the gods. This stems from deep-seated resentment over his fate, fueled by childhood experiences like being cast out of his family home during a rainstorm, which ignited his rage against divine control. His pragmatism extends to manipulation; he willingly uses friends and companions as tools to advance his objectives, a tendency fully revealed later.

Neeba's actions involve significant betrayals. In *The Sword of Uruk*, he fails to defeat the shadow of Gilgamesh and subsequently betrays his allies to seize control of both the Tower of Druaga and the Mythical Tower. This act transforms him into a physical manifestation resembling Druaga, symbolizing his corruption by power. Defeated by Jil in their final confrontation, Neeba confesses a longstanding childhood jealousy of his brother – a vulnerability previously hidden beneath his aloof exterior.

Tactically, Neeba emphasizes avoiding unnecessary combat, relying on strategic maneuvering and his archery skills. Despite cutting ties with Jil, he covertly monitors his brother's activities within the tower. His relationship with Succubus results in an ambiguous epilogue featuring a half-demon child or Succubus reverted to a childlike form.
