Inkar, a Reptilian alien from planet Zeta, belongs to Queen Zamza's faction. She arrives on prehistoric Earth approximately 330 million years ago as part of a Reptilian delegation invited by Alpha, the God of Earth, to aid in establishing a new civilization. Her activities focus on supporting the Reptilian presence, including participating in conflicts against humans resisting the alien incursion. She operates alongside fellow Reptilians like the antagonist Dahar, who targets human adversaries with traps.

Inkar reappears in later events within the franchise, maintaining her association with Reptilian forces. She is present during escalating conflicts involving deities and alien factions, confirming her ongoing role in the series' narrative of interstellar warfare and divine intervention.

While her background lacks explicit personal history or development details, her consistent allegiance positions her as a persistent antagonistic figure aligned with the Reptilian invaders across multiple installments of the official media.
