Sylar Saris belonged to a species of sentient insectoids that bore a strong resemblance to the Yam'rii species. It's possible that Saris' species was a subspecies within the Yam'rii lineage. A notable trait of this species was their ability to project a stream of green acid from their mouths.
As a member of this species, Sylar Saris operated as a bounty hunter around 18 BBY. Known as "The Slayer of Ordo Eris", he garnered significant notoriety and a high price on his head due to his work for the Haxion Brood criminal organization. Ultimately, the bounty on Saris was collected by Fennec Shand, another bounty hunter, with assistance from Hunter and Wrecker, both former clone commandos.
The species to which Sylar Saris belonged made its debut in "Bad Territory," the eighth episode of Star Wars: The Bad Batch's third season, which was initially broadcast on March 20, 2024. The episode guide released the next day indicated that Saris' species was distinct from the Yam'rii species, while also proposing the possibility of a subspecies relationship.
