"Nana" Possible is the mother of Dr. James Possible and "Slim" Possible. Much like her granddaughter Kim, she once lived a life full of adventure and danger. As a result, she tends to be concerned for Kim's lifestyle at the least, and seriously overprotective at the most. Due to her age and experience, she is the recognized matriarch of the Possible family.


Despite her age, Nana is an accomplished martial artist of the Shaolin styles, and able to keep up physically with the likes of Kim and Shego.[1][2]


Nana is the only known Possible family member who shares Kim's green eyes. She has a large aquiline nose, silver-grey hair, and a slight slouch common to the elderly.


Nana tends to be somewhat old-fashioned in her way of thinking despite her own earlier exploits. This is most evident in her treatment of Kim, who she insists on referring to as "Kimberly Ann", and takes much pleasure in dressing up in sundresses and overly large sweaters, contrary to the modern styles that Kim prefers such as her midriff bearing tops and baggy cargo pants. She is stubborn in her beliefs to the point that when she does not want to listen to something she will turn off her hearing aid. However, she is the matriarch of her family, and comes to accept that Kim is not merely in a "phase" of adventuring, but lives a lifestyle of world saving.

She has an iron will and little tolerance for panic or cowards, and tells Steve Barkin to go hide in a closet if he cannot keep it together during the Lowardian Invasion[3].


Combat Skills

By the time she was sixteen Nana had trained with Shaolin monks and perfected the ancient art of Pang Lang Quan Kung Fu, a form of Northern Praying Mantis. Although, it appears that she knows more than just Pang Lang Quan style since when she sparred with Kim and beat her she displayed a style similar to Kim general martial arts style and exceeds it.[1].

She was the first woman to complete the US Navy's underwater-demolition training program[1].

Even into her later life she clearly retained much of her martial arts prowess and military bearing.


She was a top aviatrix[1].


She was a formidable cook, famous for her lemon squares.


By the age of sixteen Nana had mastered Mantis style kung fu. Shortly afterwards she became an accomplished solo pilot. She went on to participate in and become the first female to graduate from the US Navy Underwater Demolition Training Program.

During Kim's early sophomore year of high school Nana lived either in or very near to Middleton, since James and Ann left Jim and Tim with her when they chaperoned the Mount Middleton Ski Trip[4]. Later that year, during Middleton High School's spring break, she moved to Florida[1].

Other events in her life, including the identity of Mister Possible, father to James and/or Slim, as well as Nana's full or maiden names, remain unknown.



She is known to be the mother of Slim and James Possible. It is unknown if she has any other children besides her two sons.

She is Ann's mother-in-law, as well as the paternal grandmother of Kim, Jim & Tim, and Joss Possible.


Shortly after moving into Chez Leisure, Nana made friends among the community, including Mr. Simmons, Mr. Stanley, and Mrs. Greenfield.



Nana tends towards older styles of clothing such as house coats and knitted sweaters. She has at least once worn the Kim-style uniform of cargo pants and a black turtleneck.[2]


  • Nana: Kimberley Ann Possible, you can't walk around with your bellybutton poking out like that. This is Florida, dear, not Las Vegas.


Supplementary Information


  • It is unclear if Nana's Navy training was the pre-1962 navy underwater removal school, or the more modern Navy Underwater Demolition/BUDS commonly referred to as Navy SEALs, either was possible given her age and James' attending college in the 1980s.
  • Sometimes it is difficult to correctly collate a martial arts style with its native tongue name and pinyin spelling, as there are many variations of both inflection and spelling across various Asian languages; such as Mandarin, Cantonese, Japanese, and even Vietnamese. What has been identified as Páng Láng Quán, or Northern Praying Mantis kung fu by Dr Drakken, is just as easily Pán Lóng Quán, Striking Dragon Fist. Considering Nana's style is visually nothing like Mantis, it may very well supposed to have been Striking Dragon.
  • She is the only person to consistently call Kim 'Kimberly Ann' instead of Kim or Kim Possible.


Continuity Errors

  • Nana's past represents a potential continuity error. Kim, Ron, and Wade knew very little of her grandmother's apparently noteworthy exploits until Dr. Drakken and Shego learned of them. Although, given the nature of some of her exploits it is possible that some or most of her past was classified. Or they never thought to check.
  • The fact that it is stated in during the Florida trip[1] that Ron had never met Nana before represents a highly probable continuity error since during the school ski trip[4] it was stated she lived close enough to the Possibles that they could quickly drop off Jim and Tim at her house and make it back to Middleton High School to act as chaperones. Also, Ron has celebrated the Holidays[2] with her before even though he should have met her for the first time during that year before Florida.
