Blue

Karl-591's personal AI, Blue, has been with him for the better part of five years now.

History
Al's have been apart of the Chat Empire, and many other groups, for almost thirty years now. However, most AI's are only useful for about seven years. After that, their memory banks become full and they can no longer process information or properly store it. This was the norm until KnightmareS-C075 was able to create a way around this. Using mysterious relics found in deep space, Knightmare was able to get around this block. Karl asked him to create a personal AI for him, one that would never go rampant. It took some time, but knightmare was able to create the AI, which Karl named Blue

She is always very serious and polite when it talking to people. She never curses or gets lazy, always researching things to become more knowledgeable. Blue will always address Karl as "Sir", and cares very deeplly about him. Because of this, the two have become very close to one another, caring for eachother. Blue always looks out for Karl, and puts his best intentions first. Though she knows he can be cold at times, she knows that deep side in side he does care about people. This has made her very protective of Karl, and inturn has made Karl very protective of her. Blue does ask a lot of questions but she is someone who is easy to get along with.
