“It is a pleasure to meet you master. My name is Code-AA or AA for short. I am programmed to do every household chore and play street basketball. So feel free to ask me anytime for my service.”

Code-AA, the prototype that Dr. Isaac has put a lot of effort to create is not only built for housework but is also a good multiplayer. Although her full product name is "Code-AA", the doctor likes to call her "AA". AA was built one week earlier than Code-BB. AA is always loyal and grateful to Doc for creating her. She always plays the role of a moderator whenever BB gets in a fight with Doc.

Because of Doc's exceesive greed, AA was built unusually tall for a Guard. Boasting a tall height and unreadable mechanic poker face, she is a solid force on the court.
