The Yates Family is described as being the perfect family, and they always present themselves with a wide grin. Beatrix, the oldest of the Yates children, attends a computer coding class. Bumper Jr., the second oldest of the Yates children has a whole room dedicated to all the trophies he has won. Belle, the third oldest of the Yates children, has gotten an internship at the UN, and has mastered a passage on one of Bach's musical pieces. Beau, the youngest of the Yates children, is taking a Korean-English immersion program. According to Jancey and Bumper Sr., they like to keep their kids "well-rounded", because if they're not encouraged to realize their full potential, they're failing them. The Yates parents are also shown to participate in activities that help their children, such as planting trees, watching a symphony, raising money for schools, and protecting wildlife. Lynn Sr. and Rita did things to get their kids to be like the Yates siblings. By the end of the episode, Bumper and Jancy learn from Lynn Sr. and Rita about the points of unwinding that they put their kids through. As Bumper and Jancy let their kids unwind with the Loud siblings, they join Lynn Sr. and Rita in watching a video of old people falling out of boats.
Jancey makes a cameo at the beginning of "Tripped!", where she is seen getting fashion advice from Leni.
She has a muscular body, with light fair skin, a pointy nose, two pairs of eyelashes, short wavy blonde hair, white pearl earrings, a white bracelet on her left hand, and red lipstick. She wears a white sleeveless shirt, with poofy brown shorts, a brown belt, a pink sweater tied around her shoulders, and white high heeled shoes.
Her earrings look similar to Carlota's, only white instead of gold.
Just like how Rita is the mother/wife of the Louds and she is the only Loud who's name doesn't begin with "L", Jancey is the mother/wife of the Yates' and she is the only Yates who's first name doesn't begin with "B".
He is a round man, with dark skin, and brown hair parted at the middle. He wears a white short-sleeved shirt, tan shorts, a black belt, a light blue sweater tied around his shoulders, white socks, and brown shoes.
He is a responsible and caring husband and father. He believes his children should be well-rounded, so he encourages them all to use their full potential, fearing he could neglect them. He uses every opportunity to make his family successful. However, after talking to Lynn Sr. and Rita Loud, he realized he went too far.
She is a tall, slim teenage girl with light tan skin, and long black hair with bangs, that comes down to her waist. She wears a white sleeveless shirt, blue shorts, with two yellow buttons, a teal sweater tied around her shoulders, a teal headband, dark teal slip-on shoes, and yellow hoop earrings.
Her name means "she who brings happiness" in Latin.
Belle has dark skin, dark brown hair tied into a ponytail with a pink bow supporting it, and also has braces like Luan. She wears white pearl earrings, a white long sleeved shirt, a pink sweater tied around her shoulders, tan cargo shorts, white socks worn up high, and black and white shoes.
Like Luna, she plays musical instruments, but she plays classical instruments rather than rock 'n' roll instruments.
Coincidentally, they're both voiced by Mariana Torres in the Brazilian dub.
Her name comes from the word belle, which means "Beautiful" in French.
Her brother's name "Beau" is the masculine form of the feminine word "Belle" in French.
He has brown hair, large brown eyebrows, a mole on his left cheek, a big chin, and two strands of hair that come out of the top of his head. He wears a greenish blue t-shirt, navy blue shorts, a white sweater tied around his shoulders, white socks, and white shoes.
Just like Lynn, Bobby, and CJ, he is another character who has "Jr." in their name.
He has light fair skin, light brown curly hair, and a missing tooth. He wears black glasses with rectangular lenses, a white shirt, tan cargo shorts, a yellow sweater tied around his shoulders, and white shoes.
His name means "Handsome" in French.
His sister's name "Belle" is the feminine form of the masculine word "Beau" in French.
In Korean dub, Beau speaks Belgian (Flemish Dutch or French?) instead of Korean as foreign language.
Like the Loud, Santiago, Casagrande, and possibly Spokes families, most members of the Yates family have names that start with the same letter, with the exception of the mother/wife. In this case, it's the letter "B".
The Dream Boat also shares this fact, as all the love interests on that show have names that start with "B".
This could allude to the fact that in the original pitch for the series, Lincoln was going to be a rabbit named Warren and have 25 sisters, whose names all start with "B".
Also like the Loud, Santiago, and Casagrande families, one child (the youngest among the older half) is named after the father. In this case, Bumper Jr.
