Kig-Yar (Earth-2042)

"Jackals may be superior marksmen and they're very sneaky, but that doesn't make them excellent snipers — they’re a little too bloodthirsty for that."

- Unidentified clone trooper

The Kig-Yar, sometimes rendered as "Kig-yar", are a sentient reptavian saurian species native to the moon Eayn. Following their assimilation in 11342 BBY, the Kig-Yar served the Covenant and later the Confederacy of Independent Systems until their dissolution in 19 BBY. Many went on to aid its remnants as mercenaries, smugglers, and pirates, though the majority stayed independent of any such factions. There are several distinct races of Kig-Yar. In combat, Kig-Yar typically served the Separatists as snipers and scouts due to their excellent senses of sight, smell, and hearing.
