Young teenager Leo Dooley's mother, Tasha, gets remarried to billionaire inventor Donald Davenport, & they move in with him. While trying to find his bedroom, Leo accidentally discovers teenage siblings with bionic powers living in his new basement. Leo secretly takes them to school for the first time and the show follows the bionic teens as they unravel in adventurous situations in an attempt to live life like a normal family in the fictional town of Mission Creek, California. As the show progresses in Seasons 2, 3, and 4, it gets darker with the introduction of Davenport's younger brother Douglas (turned good in Season 3), Douglas' android son Marcus, Victor Krane, S-1, Sebastian (formerly known as S-3) and Krane's bionic soldiers.
By Season 4, Davenport opens a bionic academy on a bionic island to train Krane's bionic soldiers to be the world's new heroes.
Chase Davenport (Billy Unger) is the team leader and the youngest of the three. He has incredible intelligence and is able to access a vast database of information at any time. Chase can take control over his siblings with his override application in emergencies. He also has a magnetic app. His senses are extremely powerful, including extremely sensitive hearing and the ability to see through solid matter. He can also create force fields which can be used as a weapon by shrinking them into his hand before launching them. When growing too nervous or angry, he glitches to produce Spike, a second personality who is rude and destructive. Spike has super strength, is almost as strong as Adam, and is skilled in hand-to-hand combat. A second glitch causes him to produce a sonic sneeze when his nose is irritated too much. One of his hidden powers is to manipulate energy around objects to freely move them, which he found out in Mission: Space. Another hidden ability is to levitate himself, which he revealed in Bionic Showdown. Because of the actor who plays him, Chase is also very skilled in martial arts and hand-to-hand combat.
In Brother Battle, Douglas gives Chase a new bionic ability: a bow staff that's also a laser, which he can create with his fist.
In Bionic Showdown, it is revealed that Marcus' dad, Douglas, is Chase's creator and not Donald.
In Zip It, Chase and Bree get a part-time job at Tech Store. In First Day of Bionic Academy, he becomes a mentor and trains Krane's soldiers to become heroes along with Adam and Bree. When Douglas created the Lab Rats, he was referred to as Subject C until Donald gave him a name.
He was known as Subject C because he was the third Lab Rat created.
Adam Davenport (Spencer Boldman) is the oldest and most powerful of the three with superhuman strength, which makes him one of the strongest men on the planet. Adam may not be the brightest of the trio, but he makes up for it with his great strength. He also has laser vision that can produce focused, yet intense, heat beams. When he gets too happy, he can glitch, causing him to create pulse grenades. His first hidden ability revealed is to generate a powerful force blast of electricity called a blast wave.

Her speed also grants her equally great dexterity, letting her perform feats like typing with just as much speed. One of her hidden powers is to perfectly replicate any voice or sound she has heard at least once.
At the end of Brother Battle, it is revealed that Bree was given invisibility from Douglas. When she gets too nervous, her sound-mimicking power will cause her to randomly use any of them all at once. Bree is the only member in the group to ever question how Terry still has her job despite everything she's done.
In Bionic Showdown, it is revealed that Marcus's dad, Douglas, is Bree's creator.
In Zip It, Bree and Chase get a part-time job at Tech Store.
Bree destroys her chip in Three Minus Bree after getting frustrated that she couldn't go to a concert with Catlin. After finding out Adam and Chase almost died on a mission because she didn't have her abilities to help, she realized that she was being selfish and asked Donald to make a new bionic chip. Unfortunately, because Douglas was the only one who made their chips, he couldn't repair it, leaving Bree with no bionics. When Leo goes to Douglas for help in Which Father Knows Best?, he and Donald work together and repair her chip.
In First Day of Bionic Academy, she becomes a mentor to train Krane's soldiers to become heroes along with Adam and Chase. When Douglas created the Lab Rats, she was referred to as Subject B until Donald gave her a name.

Donald Davenport (Hal Sparks) is the billionaire inventor who is Leo's stepfather and the older brother of Douglas. He is the father figure and seemingly the creator to all of the Lab Rats, but it is later revealed that Douglas is the true creator of the Lab Rats. He usually seems self-centered, childish, and a bit selfish, but he does care about Leo and the Lab Rats. He can be strict at times, especially about the Lab Rats' training or missions. Besides his intelligence, Donald is very good at martial arts and taught the Lab Rats how to use hand-to-hand combat. He may have been the only one to believe Leo when he said Marcus was evil. In Bionic Showdown, after he and the Lab Rats are captured by Douglas, he confesses to them that Douglas was the one who created them. When he learned about Douglas's evil plan to turn them into dangerous bionic soldiers, he hid them in the lab to protect them. After the events in Bionic Showdown, the Lab Rats tell Donald that he is their true father whether or not Douglas was the one who made them.

Donald then has him sent to one of his facilities to be imprisoned.
He is freed by a mysterious masked man in No Going Back. After he is freed, he contacts Donald and tells him that he is the one who maxed out his credit cards, hacked everything in Davenport Industries, and drained all his money out of the bank, and tells him that he's going after the Lab Rats and blows up the lab with Donald and Leo trapped in the lab's elevator.
