Charles Norbert "Chas" Finster, Sr. (born April 26, 1957) is the father to Chuckie, from whom he inherited his adenoidal whine, and husband to Kira Watanabe-Finster. He met, fell in love with, and married Kira in the second Rugrats movie, Rugrats in Paris: The Movie. Formerly a bureaucrat, he is now the co-owner of a coffee shop known as the Java Lava Coffee House with Kira. Chas is also Kimi's step-father. His first wife was Melinda Finster, but she passed away prior to the events of the series.


Chas is Chuckie's father, Kira's new husband, and Kimi's adoptive father. Like his son, Chas also has his adenoidal whine and also seems to suffer from many types of allergies, and appears to have asthma.

While he tends to be timid, quiet and a bit wimpy like Howard, Chas does have a much more of a speaking role. He does try to be more brave, like his son. He seems to also have a fear of clowns, Like Didi, Chas follows up on the advice of Dr. Lipschitz with caring for Chuckie, who he loves very much. However, unlike Didi, he tries doing things his own way at times. One example could be in Down the Drain, when he uses a record and his two sock puppets to try and convince Chuckie and Tommy that they don't have to be scared about taking a bath. Despite his allergies, Chas does have a garden and a greenhouse he's working on.

As revealed in Mother's Day, Chas was worried about Chuckie's lack of a mother, as he showed signs of missing Melinda. Chas does miss her deeply, but was more worried about Chuckie and his lack of a mother. In Rugrats in Paris: The Movie, he is slowly tricked into believing that Coco LaBouche is in love with him and loves Chuckie. Believing he loves her too, he comes very close into marrying her, until he hears Chuckie's first word, "no", as he rushes into the church to him. Realizing that Chuckie is terrified of Coco, he calls off the wedding. Soon after though, he falls in love with Kira, after realizing they both have more in common. Shortly after, they get married, and Kira moves in with Chas.

As revealed in The Fun Way Day, he is co-owner of the Java Lava Coffee House, with Kira co-owning as well. They buy the coffee shop in a previous episode, Sweet Dreams.

In Finsterella, Chas adopts Kimi. Chas and Kira celebrate their first Easter together in Bow Wow Wedding Vows, celebrate their first Christmas together in Babies in Toyland, and celebrate their 10th wedding anniversary in the All Grown Up! episode Petition This!, which Kimi and Chuckie throw a party for them.


Chas has peach colored skin. He has uncontrollable red hair, and a pair of purple square-lens glasses (originally green during season one). He wears a brown and black striped shirt, a purple bow tie, brown shoes, and green pants with green suspenders. His appearance and attitude depicts him as much younger than most of the other grown ups.

In All Grown Up!, his appearance changes the least of all the adults, and the only signs of his age is shown through constantly having back pains. He wears a light brown polo shirt, a red belt with a gold buckle, green high-waisted pants, and dark red shoes.


Chas appears in most episodes of Rugrats. His first appearance was in Barbecue Story, while his last appearance was in the All Grown Up! episode Brothers Grimm.

  • Chas adopts Kimi as his daughter in Finsterella. In a legal sense, that technically makes him Kimi's father and not just her stepfather.
    • Also in that episode, Kira adopts Chuckie as her son. In the same sense as Kira's, that technically makes her Chuckie's mother and not just his stepmother.
      • Since Chas and Kira adopt Kimi and Chuckie as their children, respectively, in a legal sense, that technically makes them siblings and not just stepsiblings.
  • Some of the terms of endearment used toward Chas from Kira are "Koibito" and "Koibito Doll".
