Kaiser was a crew member aboard an unnamed hovercraft, along with Cis and Duo. He oversaw a test for Cis, which involved fighting a simulation of her crewmate Duo, who she was led to believe that he wanted to be reinserted into the Matrix with the help of the Machines. Also believing that she was cut off from communicating with the rest of the crew and assuming that she was the only one able to stop him, she fought until she killed him. Upon waking up, she realized it was a test that was overseen by Kaiser and that the real Duo was still alive. Despite Cis' sucess, she punched him for tricking him and headed to the ship's elevator.
