#sector b

In Brazil, Valentine's Day (or Dia dos Namorados) is celebrated on June 12th, unlike the rest of the world that celebrates it on February 14th (Numbuh 7641's birthday). On this day, Numbuh 7641 is giving Numbuh 58-02 a Valentine's gift that is also a belated birthday gift (since his birthday is on June 3rd).

Nalio and Ophêlia Gama

Nalio is Numbuh 58-02's 5-year-old brother in which they have a love-hate relationship. They would often fight and/or argue, but they must learn how to get along. Apparently, Nalio is 58-02's rival in soccer. Nalio is currently a KND cadet, making it seem that Numbuh 58-02 was asking too much when he hoped that he would stay away from him just to not have any conflicts.

Ophêlia is Numbuh 58-02's 3-year-old sister. Her eldest brother doesn't seem to have that many problems with her, except whenever she is crying or does something wrong. Ophêlia gets scared when her brothers are fighting/arguing, prompting either one of her parents to take her somewhere calm and quiet or make her wear noise-cancelling headphones.

You may notice that they have tanned vitiligo birthmarks. Well, their brother also has a vitiligo birthmark (on his back).

Voice Claims:

Nalio — Flula Borg

Ophêlia — Debra Wilson

Folha Rição a.k.a. Numbuh 819.0

Numbuh 819.0 is Numbuh 829.0's 8-year-old sister, and the second-in-command and medic for Sector AZ (the Amazon Rainforest). She loves her brother and shows mutual respect to him. She was recruited by him when she was 6.

Her first name means "leaf" in Portuguese.

Voice Claim: Rosa Salazar

Kelo Alves

Kelo is Numbuh 7641's 4-year-old brother with type 1 diabetes; however, he learned how to be calm during his diagnosis and how to deal with it. Of course, he's friends with Ophêlia.

Voice Claim: Nika Futterman

Also, Numbuhs 74 and 190.2 are only children.

Numbuh 58-02 thinks that volleyball is too girly and that girls can't even play football (soccer), but Numbuh 74 (who is on a volleyball team) assures him that volleyball is not only for girls but boys could also play it, and that girls liker her can play soccer too.

They wear these outfits when going on extremely dangerous missions, such as terrorist or gang wars, even when the police had no control. The uniforms are Brazilian-themed because Sector B is canonically located in Brazil.

Fun fact: Numbuh 7641 originally had long hair at the start of the series before having it cut at the start of season 3.

(Update 12/23/2025: Gave them real names)

Sector B was mentioned in the show, but since no one came out of it, me and TrentPage (who is on DeviantArt) made headcanons of the operatives of that sector.

Sector B is a sector that is located in Rio de Janeiro, Brazil. With violence and terrorists evolving around the country, this sector was formed to battle against those forces. They are rivals with @the-raddest-potato's Sector Y.

I just needed a breather from all the drama, anxiety, and stress I'm currently going through on the internet and IRL (at my current age), so I drew Numbuh 7641 doing one of her yoga routines, which she does every Sunday with her mother (who is a yoga instructure).
