Bionic Abilities

Bionic Physiology: Since Bree is a genetically engineered human, she is able to withstand the harshest temperatures, mostly due to wearing her mission suit, which can accommodate to any weather. She gains most of her powers from a chip designed by Douglas and Donald Davenport.

  • Super Speed: Bree's main ability. She is able to move fast like the speed of light, meaning she goes unseen by the human eye rather quickly. When people hold onto her, she is able to super speed with them. She can blast her enemies with her speed blast, can direct where her speed can go through her mental navigation,
    • Speed Jump: Bree is able to super jump over anything easily, transporting herself onto the ceilings and does not need any support.
      • Sticking on Walls: Bree can also stick to the walls but she is still affected by gravity, as her hair clip fell out of her hair.
    • Speed Talking: Bree was able to summarize the episode of "Mission Invisible" to Donald in under five minutes.
    • Speed Fighting: Bree can speed fight, which she uses against her opponents.
    • Speed Typing: According to Bree she can type all the words in the universe per minute, as she did so when launching a missile to stop a solar flare from destroying the earth.
    • Speed Drawing/Painting: When Bree and her brothers ruined Donald's painting, she was able to paint a replica while looking at the picture once. She speed-painted so well that no one could tell if it was a fake or not.
    • Mental Navigation: Bree has a navigational system in her super speeding, which is why she is able to navigate to herself from place to place.
    • Speed Blast: To catch her enemies off guard, Bree can blast her enemies with her speed blast
    • Vacuum Generation: Using her super speed while running in circles, Bree is able to create a vacuum. She used it to slow down a collider and used it to suck flies back into a canister. She could also use it to stop a fire from breaking out, according to Chase if she hadn't destroyed her chip.
      • Sonic Whirl: She can super speed around her enemies, as she used it against Gamma Girl.
      • Sonic Cyclone: She can create a sonic cyclone, which she did when she took Ethan for a crazy dance. speed drawing and painting, vacuum generation, speed whirl and sonic cyclone
    • Super Agility: Despite being agile already, Bree has better agility than any of her brothers.
  • Invisibility: Douglas gave her the ability to turn invisible. She used it while sneaking in Troy West's place.
  • Vocal Manipulation: Bree can manipulate her vocal cords to sound like another person or another object. When she first got the powers, Bree began abusing it (mostly from Leo's urging). However, she learned to never use that bionic ability ever again.
  • Super Durability: Being genetically engineered, she can stand more punishment than normal humans. She could be stunned by lasers that could actually kills somebody.
    • Resistance to Extreme Temperatures: Bree can resist extreme temperatures thanks to Genetic Engineering. However, she cannot withstand the hostile temperatures of the planet Caldera, as she needed a regulator patch to survive the planet's hot climates.
  • Bionic Fusion Attack: Bree's Bionics can be linked to Chase's and Adam's through Chase's Override app, allowing them to create one large fusion attack. Bree must be overridden by Chase, along with Adam, and then the three must stand in a perfect triangle with their arms linked. Then the energy will be charged up, and once it is ready it gets blasted from Chase's side. However, it will cause them to pass out as it is very draining and is only used as a last resort.

Super Powers

  • Superhero Physiology: After indirectly touching the Arcturion through Skylar, Bree gained superpowers.
    • Thermal Touch: A sub ability of Pyrokinesis. Much like the bionic soldier "Thermo Hands" from Lab Rats, Bree can burn anything with her touch.
    • Proton Ring Generation: Bree has the ability to create laser energy rings (although they look more like discs) that work similar to boomerangs by moving around in a full circle, hitting opponent, and then returning to Bree's hand. She gained it after touching the Arcturion. They are very powerful as they were shown to knock Scarlett into the sky.
    • Thermo Nuclear Body Blast: Bree's body begins to glow bright green and then forces out a blast of green energy out from her arms. It looks very similar to her brother Adam's bionic Blast Wave ability. It is likely the most powerful out of all her abilities, bionic or super. She first used it in Home Sweet Home to knock out Scarlett.
    • Electrokinesis: This power first manifested in the form of light beams shining from Bree's palms, similar to flashlights. However, when she combines the beams of light, they form a giant ball of electricity, which she can then blast at an opponent, shown when she used it to incapacitate Rodissius.


She is the middle child of the bionic trio and the only girl. She likes talking to her friend, Caitlin, and giving her misguided boyfriend advice, as shown in Can I Borrow the Helicopter?. She, as every other teenage girl, tries to be normal, aside from the fact that she is bionic. She is also somewhat irresponsible and has reckless tendencies. She often overreacts to situations, but is still kind at heart and deeply cares about her family. She's sassy, opinionated and very sarcastic, with a snarky sense of humor, always with a smart retort ready. Although she complains about them a lot, she loves her brothers. She likes to annoy her little brother, Chase, with them often bickering or poking fun at each other. Her relationship with Adam is more positive, though they still bicker. She often breaks up fights and arguments. Though proud of her femininity, she has her tomboyish qualities, most likely due to her lack of interaction with other girls. However, she's become more lady-like in later seasons. Despite being brave, Bree can be squeamish when forced to deal with disgusting things. She is also shown to adapt to cultures quickly, as shown in Drone Alone.


Chase Davenport

Chase is Bree's brother. Like most siblings do, they tend to tease/bicker each other. They'll insult each other and argue, but in the end, they're always there for each other. Their friendship is strong. These two will fight at times, but their fights never affect their connection with each other. In Bionic Showdown, Bree fought Marcus in attempt to save Chase. In Bionic Action Hero Bree cries a little when she thinks Chase is dead, and blames herself for it since she was the one who gave Troy Chase's chip schematics. They care about each other a lot, and have a close relationship. At the end of the series, they both decide to stay with Davenport's new team, and they both join the Elite Force.

Adam Davenport

Adam is Bree's brother. They tease one another once in a while, but rarely fight or argue.They care about each other a lot, and their relationship is very strong. They're very close to each other and will always be there for each other, no matter what. Adam is softest to Bree the most. In Bionic Showdown, Marcus made Adam fall to the ground twice and get knocked out for a while, causing Bree to run to him in concern. In Bionic Action Hero, Adam was reluctant to hurt Bree, and was the last to turn his power on. When Bree told him to destroy her and Troy, Adam told her "I can't." They care about each other a lot, and have a close relationship.

Leo Dooley

Leo is Bree's younger cousin/brother by her adoption. They insult each other from time to time, and they tease. Bree puts herself in a position as Leo's older sister, and makes him pay the consequences to his mistakes, as shown in Spy Fly She claims that she wants him to follow his responsibilities as she does with herself. They're always there for each other and care deeply about each other.

Donald Davenport

Donald is Bree's uncle and adoptive father. She continues to call him her dad, even after she discovers he has been lying to her and her brothers. She sometimes ignores his warnings and goes against it, leading her to fall into trouble. Bree isn't as close with him as the boys are, but he will be a fatherly figure towards her at most, even though she finds it embarassing. When Davenport realizes how little time he spent with her, he made it up to her with his Concert in a Can.

Tasha Davenport

Tasha is Bree's Aunt/Mom by her adoption. She appears to get along with her, mostly because she's the only other girl in the household. Tasha tries to act like a mom to her and gave her advice about a guy she liked. In Can I Borrow the Helicopter?, Tasha makes Davenport let Bree move into her sewing room so she could have more space and privacy. Bree, happy about this, was glad Tasha convinced him, up until she realized she was taking up her space and privacy. In Prank You Very Much, Tasha helps Bree prank Adam and Chase, and In Cyborg Shark Attack Bree was going to go get her nails done with Tasha. Bree is assumed to be Tasha's favorite, since she's the only girl. However, along with her other siblings, Tasha is still not completely set with Bree (and her brothers) living in the house, due to the fact that they are bionic.


  • She is the world's second bionic superhuman, and the world's first female bionic superhuman.
