Jabby hails from an alternate Earth where his reptilian species emerged as the dominant lifeform, characterized by brown skin, powerful hind legs, elongated three-fingered arms, a serpentine neck, and a tail attuned to sensing dimensional anomalies. This unique appendage enables him to identify "singularity points"—individuals pivotal to maintaining space-time stability.

As a strategist aboard the Glomar, he offers tactical expertise during confrontations and coined the mecha’s name "Orguss" in homage to a war deity from his dimension. His pragmatic yet loyal demeanor aids the crew in navigating multidimensional complexities, blending analytical guidance with steadfast allegiance to their objectives.

Tied to a civilization versed in dimensional mechanics, his background hints at advanced understanding of such phenomena, though specifics of his culture remain uncharted. Jabby maintains a consistent role as a mission-driven ally, prioritizing operational efficiency over personal growth. His interactions with the crew center on operational synergy, reinforcing his position as a strategic resource within the team.

His species’ broader societal context, extended origins, and activities beyond the primary series’ timeline remain undefined in existing records.
