Kappa is a Artificial Intelligence fragment of the Alpha AI of female programming. She represents the Alpha's compassion and love, and was taken from A.I. Containment Facility by Captain Lux Chapel of the Alpha Blues. Chapel was able to actually stabilize her, and was able to become like her brethren AI fragments that was successful. Thankful that Lux got her out, and able to "repair" her, she became a close friend and companion to Lux, and a semi-friend to the Alpha Blues. Oddly enough, she is also the AI that allows Lux to use the Strength Boost and the Active Camouflage armor enhancements on the field.
As Alpha's love and compassion, she is a caring and kind AI. She always reminds Lux to check all vitals of his Alpha Blues, and she always sync with all the soldiers who's with Lux, making sure they are healthy and clean. When she does try to insult and be menacing, it seems to backfire as she used caring words for it. Making it sound odd to the enemy. And to everyone around her.
