Mr. Ko is the "father" of Kitty. He bears a similar appearance to and acts like his daughter. He, along with Mrs. Ko, were built by Kitty to serve as her parents. Mr. Ko, along with his "wife" are able to join together and become a robot.
Mr. Ko wears a white t-shirt with a green tie along with black pants. His hair is neat and his face and build is shaped exactly like his daughter's.
Mr. Ko, like his wife, is a strict parent, often wanting Kitty to succeed and get perfect grades, especially when Pamplemoose said that she was a good student, but Mr. Ko noticed one "B" and got angry.
- Its robot form bears physical similarities to a Gundam.
- No information is given on what happened to the real version of him. It is most likely that he (along with his wife) either abandoned Kitty (possibly as a baby), got killed or both.
- Mr. Ko is voiced by Denise Oliver who also voices his wife and daughter.
