Paaerduag

At birth, the two humanoid components were separate beings, which as they grew up, fused together. It seems the larger creature controlled movement as the smaller creature would tell it to turn around so it could see things opposite itself. Paaerduags were seen often around the time of the Jedi Civil War, and Revan encountered two Paaerduags during his travels; one named Ja'Gatcha, who was trapped on Taris due to the Sith quarantine and was likely killed when Darth Malak's fleet bombarded the surface from orbit. Another was named Mic'tunan'jus Orgu, a merchant in Anchorhead on Tatooine.
