Kia was one of the three Brotherhood of Shadows henchwomen in MK Mythologies along with Sareena and Jataaka. They were sent to hinder the elder Sub-Zero (Bi-Han) as he pursued Quan Chi to get the amulet before the sorcerer gave it to Shinnok. However, one of the three henchwomen has a face turn, while the other two pretty much disappeared.
How would Kia have fared if she had a face turn much like Sareena? She sure sounds like she has a lot of potential as a character.
