Kule Vars (Earth-5875)

Kule Vars was a sangheili First Blade officer of the Silent Shadow, who was dispatched alongside his unit to the human colony Terra Nova to investigate the mysterious disappearance of a reconnaissance team and locate forerunner artifacts, being ultimately used by Specimen 6 to create the Abomination.

The Covenant
Kule Vars was one of the sangheili warriors who oversaw the initiation training of many zealots on Yautja to become a part of the Silent Shadow alongside a Minor Prophet. After witnessing Dahr 'Volir's bloodlust and proficiency with an Type-1 energy sword, he granted him the rank of First Blade officer.

Battle of Terra Nova
Days later, Kule, Dahr and two other Silent Shadow were sent by the Hierarchs to the human colony Terra Nova to investigate the mysterious disappearance of a reconnaissance team and locate forerunner artifacts. Upon their arrival on the planet in a CCS-class battlecruiser, the four sangheili shot down the human ship UNSC Marlow in Walter's orbit, only to split up once they landed on the surface. After hours of search, Hunter saw two Special Operations sangheili battling a swarm of xenomorphs in an ancient forerunner installation, however, he was too late to save them. Leaping into battle with rage, he was determined to avenge his fallen brothers, killing all flood present, except for one, Specimen 6. The two engaged in a bloody duel, with Vars showing great use of his energy sword, cutting two of Specimen 6's fingers.

Death
Using his strength and intelligence, he attempted to outsmart and overpower 6, but his pride became his hubris once he taunted the apparent dead enemy instead of killing it, with 6 impaling Kule with its trail, crippling him. Wounded and defenseless, Specimen 6 removed his helmet and placed a Facehugger on it, with the embryo being planted inside him and later hatching and maturing into the Abomination.
