Remart Sasyru was a physically imposing and attractive Human male who served the Invids as a member of the Khuiumin Survivors in Bolt. This Human male was characterized by his height, muscular build, and handsome features, which included dark black hair of medium length and piercing blue eyes. He also sported a goatee paired with long, stylized mustaches that resembled wings.
Sasyru's career among the Survivors began within Rock Squadron. Displaying a clear preference for furry humanoids, Sasyru cultivated a relationship with Caet Shrovl, an albino Shistavanen wolfwoman who was also a member of Rock Squadron. However, his motivations were far from honorable. He manipulated Shrovl, fostering a sense of trust, only to later make unacceptable demands of her. When she refused his advances, Sasyru resorted to physical violence, severely beating the Shistavanen. His transfer to Bolt, the Survivors' elite squadron, was ostensibly a great honor, but it was his deplorable treatment of Caet that led his fellow squadmates to expedite his transfer at the earliest opportunity.
The arrival of Corran Horn, operating under the alias Jenos Idanian, within the Survivors ignited an immediate and intense rivalry between the two pilots. This animosity was widely recognized among the Survivors. Much to Sasyru's frustration, Leonia Tavira personally promoted Corran to the position of Captain of the Bolts. However, in retaliation for Corran's rejection of her advances, Tavira chose Sasyru as her consort, a decision made solely to provoke Corran, and it succeeded in its intent.
During a mission to Kerilt, a Caamasi colony world, Sasyru attempted to pilfer valuable heirlooms from the colonists. When a young female Caamasi, Releqy A'Kla, requested to retain a specific heirloom, Sasyru offered to comply only in exchange for sexual favors. Upon her refusal, Sasyru attempted to assault the young Caamasi. Her father, Elegos A'Kla, intervened, and Sasyru attacked him. At that moment, Corran arrived on the scene and skillfully provoked Sasyru into a physical altercation. Sasyru proved to be no match for Corran, and his handsome features were brutally disfigured by the furious beating he received. Upon their return to the Invidious, Tavira ordered Sasyru's execution for insubordination and assaulting a superior officer.
