Beatrice "Betty" Barrett (also known as Atomic Betty) is the show's main protagonist (voiced by actress and singer Tajja Isen).

On her home planet Earth, and most of her friends and family in her hometown of Moose Jaw Heights, young Betty Barrett is an average yet cute and tomboyishly beautiful 7th-grader middle school student who is highly athletic and loves every single sport that she tries, especially ice hockey. She even enjoys singing in her band. She is also a member of the Galactic Guardians.


She enjoys visiting her grandmother Bea on her farm, which is located outside of Moose Jaw Heights, singing with her friends in her band, joking off, hanging out with her best friends and daydreaming about living in outer space. She is not afraid to speak her mind on any subject, and she dislikes all forms of bullying, snobbery and unfairness.


However, when there is trouble in outer space, she is called on by her friend and her commanding officer, Admiral DeGill, and along with her crew, is the captain of her own starcruiser under her secret identity of Atomic Betty, who is revered throughout the galaxy as a well-known and quite famous Galactic Guardian and Defender of the Cosmos.

When in outer space, she and her crew, a food-loving, green-skinned alien assistant named Sparky and her robotic navigator and second-in-command named X-5, investigate various intergalactic crimes and fights evil supervillains. An expert hand-to-hand fighter, kickboxer, an expert in karate, she can easily defend herself against most opponents, but is also equipped with a special Galactic Guardian-issued utility bracelet, which houses other technological devices, such as a holographic communicator she uses to speak to Admiral DeGill, her commanding officer and her crew, remote controls for her starcruiser and its teleporter, as well as an arsenal of gadgetry and weaponry to use on her missions.


In the first season of Atomic Betty, Betty at first thought that she was the only human ever to be chosen to be a Galactic Guardian, until she discovered her grandmother was a retired Galactic Guardian named Beatrixo, and also one of the first Galactic Guardians.


Betty is a human with fair skin, long red hair and lime-green eyes. She usually styles her hair in a ponytail, although when wearing certain outfits, such as her swimwear or winter coat, she lets her hair down, revealing that it is waist-length.

On Earth, her usual outfit consists of a white long-sleeved collared shirt worn underneath a yellow V-neck long-sleeve sweater with green stripes on the sleeves and a green line on the v-neck, a green knee-length skirt, white knee-high socks and black and white tennis shoes. She also wears a green headband on her hair.

When on a mission or doing Galactic Guardian stuff, she wears her standard Galactic Guardian uniform, which consists of a white helmet, pink dress, white gloves, pink bracelet, white belt with a nuclear symbol, and white thigh-high boots. She also wears red lipstick.


Betty is a very smart, pretty, happy, funny, strong-willed, tough, pleasant and very independent young girl with highly eccentric interests, and is not afraid to speak her mind on any subject. Despite her cuteness and kindness, she also has a bit of a temper, and can get easily annoyed, most often by her rival Penelope Lang.

On Earth, she likes playing pranks, listening to music, reading her sci-fi comics, popping an Ollie on her skateboard, hanging with her best friends Noah and Paloma, or daydreaming about her crush, Dylan.

In space, she loves protecting the galaxy with her gang, flying in her starcruiser and karate-chopping treacherous galactic supervillains. In the episode Attack Of The Evil Baby, Betty was scared to get her tooth out when she went to the dentist with her mother.


Betty does not possess any superpowers, but she is exceptionally strong and agile for a girl, despite her beauty. She is an impressively tough fighter and has a good knowledge of galactic combat techniques, as she's been seen being able to take down much larger alien opponents with one punch or kick. She is also wields a laser sword as shown in The Trouble with Triplets. She is also a very capable Galactic Guardian captain and a very good leader, though at times she can be a bit bossy to her crew. She has also shown exceptional prowess in nearly all sports, including both skateboarding and surfing.

She is shown to have some slight mystical abilities in the episode Spindly Tam Kanushu, where she uses a special meditation technique to locate the exact planet that her alien martial arts master, Spindly Tam Kanushu, has been taken to by Maximus.

  • Betty is not a very good detective because she saw some clues of her grandmother Beatrixo being a Galactic Guardian and her friend Paloma is an alien, but she dismissed them due to the fact that most people on Earth don't believe aliens are real.
  • In Season 1, Betty has a high, "childish" voice while spoken. When Tajja turned 13, she provided her voicing role of the show's main character, but also performed numerous tunes in voice recording.
  • She was originally 8-9 according to concept art.
