XindiReptilian

The Xindi-Reptilians, also known as Xindi-Reptoids, are one of the five subspecies of the Xindi, a technologically advanced alien species from the non-canonical Star Trek television series Star Trek: Enterprise. The Xindi-Reptilians are a reptilian humanoid species originating from the Xindi's homeworld, Vulcan-like planet Xindus III.

Physically, Xindi-Reptilians are characterized by their scaly, reptilian skin and elongated heads with neck joints that allow for a wide range of motion. They have sharp teeth and claws, indicating their aggressive and highly predatory nature. Xindi-Reptilians are bipedal and mostly slender in appearance, with most adult individuals reaching a height of approximately 5 to 6 feet.

According to the Star Trek: Enterprise series, the Xindi-Reptilians are a largely militaristic society, placing a strong emphasis on conquest and territorial expansion. In contrast to the more ethereal and philosophical Xindi-insectoid, the Xindi-Reptilians are pragmatic and willing to do whatever it takes to achieve their objectives. This aggressive nature often leads them to engage in violent and destructive behavior.

During the Xindi War on Earth, a subset of Xindi-Reptilians formed an alliance with the human Enterprise crew, betraying their own species to prevent a war that would have most likely erased Earth from existence. However, their subsequent attempt to kill the Xindi Prime leaders backfired, highlighting a deeper agenda to disillusion their own unstable collective to listen solely to their ruler windsup thus ending the story with internal power development.
