Voiced by Jean Smart.
Kim's mother is not only a neurosurgeon, usually referred to as a brain surgeon in the series, but also a caring mother to Kim, and seems to be more understanding toward her daughter. In season 4 her name was revealed to be Ann Possible by her brother-in-law Slim Possible in "Graduation Part 1". It was also revealed in season 4 that she was a graduate of the University of Upperton. In Mother's Day she goes on a mission with Kim and saves Kim from being swallowed by a glob of green goo by using her Kimmunicator to send high-frequency pulses to attack it.
Ann looks identical to Kim, but is taller in height with lighter hair, blue eyes and a more pinkish color to her skin.
Ann is a nice but firm person, with a cheerful attitude. She is also very understanding. Like most redheads, she has a hair-trigger temper, which Prince Wally almost found out first-hand. In her eagerness to be accepted by her daughter's peers during a Sophomore ski trip weekend, she forgot her boundaries and unintentionally embarrassed Kim.
Ann is able to do the puppy-dog pout, just like her daughter, often to get Kim to cave in to her mother's wishes.
Ann graduated from the University Of Upperton.
Ann worked as a skilled neurosurgeon at the Middleton Medical Center. She is an excellent parent who exhibited remarkable adaptability to uncertain situations during her brief forays into heroics alongside her family.
- Dr. James Timothy Possible (husband)
- Kim Possible (daughter)
- Jim and Tim Possible (sons)
- Slim Possible (brother-in-law)
- Joss Possible (niece)
- Nana Possible (mother-in-law)
- Larry (nephew)
- Aunt June (sister or sister-in-law)
Ann often tended to serve as the voice of reason in her family. She scolded Jim and Tim when they experimented in the house, offered Kim motherly advice on various social challenges, and constantly reminded her husband, James, to be home in time for dinner.
She was apparently well liked outside of her immediate family as well. Her brother-in-law, Slim, asked after fondly when she was unable to visit his ranch with the rest of her family.
Ann appeared to be on good terms with her coworkers. One of Kim's pet peeves was that Ann would accept personal calls from her while performing surgery and put her on speakerphone, which allowed Ann's coworkers to listen in and comment.
