Kimi Finster

 Kimi Watanabe-Finster is a fictional character on the television shows Rugrats and All Grown Up. She is also the step-sister of Chuckie Finster. Introduced in Rugrats in Paris: The Movie, she is voiced by Dionne Quan. Born into a Japanese family, she was the last character to be introduced to the Rugrats character list when her mother married Chaz Finster, the father of Chuckie Finster, a regular character on the show. She later appeared in the series All Grown Up!.

Rugrats
Kimi was the last addition to the cast of Rugrats, making her first appearance in the second Rugrats movie, Rugrats in Paris: The Movie. In Rugrats, the one and a half year old Kimi was portrayed as very brave and often stumbled into dangerous situations she was too naïve to recognize, often bringing her new brother, Chuckie Finster, along, much to his dismay. He described her as "another Tommy" upon meeting her.

She is depicted as being chubby with purple hair, tied up in three pigtails on top of her head and a yellow dress similar to Suzie's, wearing a diaper underneath and purple shoes.

She was introduced as Chuckie's new sister, after her mother, Kira Watanabe-Finster, married Chuckie's father, Chaz Finster after she divorced Hiro Watanabe. This marriage and the changes it brought to the Finster family were used in Rugrats to teach the child viewers, by demonstration, about adapting to such drastic changes caused by divorce and remarriage.

All Grown Up
In All Grown Up!, set approximately nine years later, Kimi grew up to some extent. Her age is never clearly defined, but it is largely assumed that she is 10 years old. Kimi is still a little adventurous. At a ski resort, while Angelica signed up for spa-like activities, Kimi signed up for athletic activities like rock climbing. She had a tendency to buck the trend on how she feels about and treats less popular kids, including Z. She was also portrayed as being supportive of her best friend Susie when she was in need. When Susie is having problems, Kimi is usually there to help. However, she is also portrayed as having a tendency to hold grudges.

Angelica Pickles could be considered somewhat of an associate, but grudgingly so on Kimi's behalf.

Kimi first has medium length hair that is left loose but with a section in a ponytail. She gets a pink fauxhawk in the episode Bad Kimi which she keeps just for that episode. She dresses at first in punk rock outfits but in season 2, she receives a new look: her hair is in two pigtails that stick out on top of her head (her hair is shown to have grown waist-length in one episode) and wears jackets and knee-length skirts.

Character synopsis
There are several episodes where Kimi could have had character development but did not. The traits usually disappear after one episode.

Kimi also seems to be a born opportunist, ready to nip any golden opportunity in the bud as it comes. A classic example can be found in the episode, "Chuckie's In Love", where she sees a chance to attend a Sulky Boys record signing with Lil by letting Chuckie take over her shift (which, incidentally, falls at the same time as the signing) in exchange for a makeover.

It's been revealed in the episode "Dude, Where's My Horse?" that Kimi cannot cook.

She is also extremely fond of animals.

Kimi works part-time at the Java Lava, her family's coffee shop, with her brother, Chuckie, her father, Chaz (who is the owner of the Java Lava).

She revealed in "TP + KF" that she carved the said initials in the Finsters' cellar years ago when she had a crush on Tommy although Tommy said that he wasn't attracted to Kimi but later in the episode it was proven the two had feelings for each other. In the pilot episode "All Growed Up" she has only four lines and then never said one word throughout part two of the pilot.

Kimi speaks her native language, Japanese, on All Grown Up very briefly on the episode 'Memoirs of a Finster' when she does a report on her Japanese heritage.
