Main Characters

    Chase Davenport 
Played by: Billy Unger
  • Academic Alpha Bastard: To the point he wants things done his way, not anyone else's. This is why Adam tells his students "Don't be like Chase!"
  • Badass: He knocked Marcus out simply just by doing a roundhouse kick. And that's just one example of what he is capable of.
  • Badass Armfold: Take a look at the picture.
  • Badass Baritone: As Spike.
  • Badass Bookworm: He's gotten to show off his martial arts skills many times in the show.
  • Barrier Warrior
  • Beauty, Brains and Brawn: The Brains.
  • Berserk Button: Don't say you're smarter than him. Sebastian learned that the hard way. That goes for you too, Donald. Another one is when Bree flirts with some other boy, though he had no problem with Bree flirting with Oliver.
    Chase: (to Sebastian) Don't EVER say that again
  • Brainy Brunette
  • Pink Girl, Blue Boy: Blue to Bree's pink
  • Butt Monkey: He's always picked on for his inability to get girls or for being short.
  • Control Freak: Lampshaded by Bree in Unauthorized Mission.
  • Deadpan Snarker: He and Leo are the master snarkers of the show.
  • Et Tu, Brute?: Chase was greatly hurt when Sebastian betrayed him after he thought he was as innocent as all the other soldiers were. In One of Us, he believed S-1 may do the same, showing just how badly Sebastian wounded him.
  • Fiery Brunette: Only when things don't go his way. He even wanted to fight Sebastian.
  • Foolish Sibling, Responsible Sibling: The Responsible to Adam, Bree, and Leo's Foolish.
  • Flanderization: He changed from a Control Freak with some heart to a big try-too-hard perfectionist in Late Season 3 and Season 4.
  • The Friend/Sibling Nobody Likes: Due to his Type A personality and him being an Insufferable Genius, people don't seem to like him. It's also because of his constant reminding of him being mission leader and being a tattletale. Bree said it herself:
    Bree: And you wonder why no one at school likes you.
  • Genre Savvy:
  • Hair-Trigger Temper: In Season 4, he lets his temper get the best of him in Stimulation Manipulation. When his temper gets driven high, he will become Spike.
  • The Hero: Seems to share the role with Leo.
  • Hero Antagonist: He sometimes gets into this. An example is in "Zip It" he destroyed Bree's only chance of having a job as a normal teenager. Ever since Season 4, it stuck to him.
  • Hollywood Nerd
  • Insufferable Genius: All the time.
  • Jerkass Teenage Son: Shows this often in Season 3 and 4. Bree is much worse than he is though, but on her worst days.
  • Like Father, Like Son: Technically, uncle. Chase and Donald are both snarky Insufferable Geniuses.
    • A straighter example is him and his actual father, Douglas. To begin with, both were picked on by their older sibling. Both are geniuses who feel like they are overshadowed by their older siblings, and seek recognition. This is what Douglas tries to exploit in Chase.
  • Mind over Matter: Called 'molecularkinesis', it's Chase's hidden bionic ability.
  • Mr. Fanservice
  • My Sister Is Off-Limits!: Every time Sebastian hits on Bree, he always yells at him for it.
  • Nerds Are Sexy: Billy Unger has a lot of fangirls. In universe however, girls never ask him out.
  • Nice Job Breaking It, Hero: When he told Sebastian the truth about Krane being killed off in Unauthorized Mission it causes Sebastian to start a rebellion. In the next episode, the fourth season premiere AKA Bionic Rebellion, Chase unlocks a new ability for Sebastian, tells him Davenport's password for unlocking new abilities, and leaving Sebastian alone so he can give himself every ability. Almost the entire season four premiere was a Nice Job Breaking It, Hero moment for Chase, to the point where Adam says "It was all Chase's fault".
    • When S-1 came to the island, Chase made sure NOT to make the same mistake of assuming any lead soldier of Krane is an innocent blank slate, because he remembered what happened the last time he did. Chase ended up being wrong about S-1, but at least it shows he learned from his mistake.
  • Not Quite Flight: In "Bionic Showdown", Chase revealed that he has a second hidden bionic ability - the power to levitate himself.
  • Only Sane Man: Having Adam and Leo joking around in very serious and uncalled moments, Bree being the Bratty Teenage Daughter, and Donald being unmistakenly crazy, Chase is definitely sharing this trope with Douglas (even though Douglas has destructive tendencies and doesn't always play by the rules).
  • Parental Favoritism: Bree states that he is Donald's favorite of the three. Given his potential to be the most powerful, it seems he is Douglas's favorite too.
  • Personality Blood Types: Type A. He is bossy, controlling and a workaholic
  • Red Oni, Blue Oni: His bossiness and Type A personality makes him the Red to Adam and Bree's Blue
  • Relationship Sabotage: Before Sebastian turned evil, he tried to ruin Sebastian and Bree's constant flirting.
  • Savvy Guy, Energetic Girl: Savvy Guy to Bree's Energetic Girl
  • Shorter Means Smarter: However, do not emphasize the "short" part, as it is a source of angst for him.
  • The Smart Guy
  • Smug Snake: At times. The principle Adam has his students follow is "Don't be like Chase".
  • The Spock
  • Super Intelligence: Doesn't mean he can account for every flaw when he solves a problem. However, he is shown to be even more intelligent than Horace Diaz, that Kaz had to borrow it to cure him.
  • Superpowered Evil Side: Well, not exactly evil, but Spike is far more anti-heroic than Chase.
  • Teen Genius: Subverted, his intelligence is literally stored in his chip. Without his chip, he only has average intelligence at maximum, and only has a rough idea of how to solve problems.
  • Took a Level in Jerkass: Not so much compared to Adam, but he did become more egotistical and cocky in later seasons, which leads to his incompetence as a mentor.
  • The B Grade: Freaked out when he got an A- in "Smart and Smarter"
  • Youngest Child Wins: It turns out when Douglas created the Lab Rats, Chase's bionic chip was a later version of Adam's and Bree's, which means he theoretically has more room for upgrades.


Played by: Billy Unger

    Adam Davenport 
Played by: Spencer Boldman

    Bree Davenport 
Played by: Kelli Berglund

    Leo Dooley 
Played by: Tyrel Jackson Williams

  • Adorkable
  • Action Survivor: A given when your living with the most biologically advanced humans on the planet. In addition, Leo has survived a lot of things that almost killed him. This is deconstructed in You Posted What?!, where S-1 collapsed a beam on Leo cost him his arm. Had the fire department not acted quickly, Leo would have died of blood loss.
  • Artificial Limbs: Douglas had to install bionics in his right arm, because it was completely damaged beyond repair. Later in the series he gains a bionic leg after a botched rescue attempt to save Donald (Leo used his bionic arm to catch falling shuttle only to find out right after that Donald parachuted out at the last moment). As the shuttle was too heavy and accelerating too fast for Leo's arm, he tried to jump clear of it only for the shuttle to crush his leg.
  • Badbutt: Come on. He saved the Lab Rats from being crushed (and nearly bought the farm himself), went to help Davenport in the tunnel when the other couldn't, stopped a virus-crazed Eddy, and stood up to Marcus, even when threatened with his Eye Beams (and after Marcus had already tried to kill him once before, because he saw Leo as a threat).
    • Took a Level in Badass: In You Posted What?!, Douglas enhances Leo's arm after it is crushed and it is now bionic. Giving him the bionic abilities include healing quickly, throwing energy balls, and increased physical strength. But only in his right arm. However, his aimis quite terrible, and he still needed more practice.
      • Upgraded his status again in "Rise of the Secret Soldiers" when Douglas unlocked his new bionic power of energy transference (which allows his to absorb any form of energy from a source and redirect it back at a target and he used it in his one-on-one battle against S1 and easily defeated her.
  • Black and Nerdy
  • Butt Monkey
  • Cassandra Truth: No one believes him when he says Marcus is a "bad dude".
  • Child Prodigy: Despite Donald's criticism, did you see just how effective Leo's 'attack orbs' were? Sure, they were flawed, but still excellent effort.
  • Clingy Costume: Solidly under the Rule of Funny, as it's adhered to him in a way he's no longer comfortable with.
  • Crouching Moron, Hidden Badass: A bit goofy but still had the guts to stand up to both Marcus and Krane.
  • Deadpan Snarker: He and Chase are the master snarkers of the show.
  • Foolish Sibling, Responsible Sibling: The foolish to Bree and Chase's responsible and the responsible to Adam's foolish.
  • I Just Want to Be Special: No matter how far Leo gets, he still feels this way every time.
  • Jerk with a Heart of Gold
  • The Klutz: Apparently, he's broken a lot of Donald's stuff.
  • Literal-Minded: His response to Perry after she wakes up:
    Perry: What is all the yelling about? I didn't have time to put my face on!
    Leo: Wait, that thing's removable?
  • Mission Control: As of "Missin' The Mission".
  • Muggle: He's slowly moving out of this, as he's becoming more and more involved with missions and the overall operations side of the Lab Rats' work.
  • Plucky Comic Relief: Problem is, he wants to be seen as more than that. The President thinks all he brings to the Team is comic relief.
  • Secret Keeper: Though some of Davenport's projects are public knowledge.
  • Screams Like a Little Girl
  • Shorter Means Smarter: As short as Chase, but he is nowhere near as smart as him or a doctor.
    • Not yet - but if the scientist from the Christmas episode "'Twas The Mission Before Christmas" is any indication, Leo could be serious competition someday.
    • Few episodes in season 3 feature him trying to invent gadgets that usually end up going awry.
  • The Strategist: He usually comes up with the plan and as of "Missin' The Mission", he's been promoted to strategic mission specialist.
  • Stylish Protection Gear: Leo's new team uniform. It looks good, with a hood and a red right sleeve (the hood's also red) .
  • Supporting Protagonist: Much of the series is told through his eyes as he follows the Lab Rats, witnessing firsthand the lives and missions of the world's first bionic superhumans.
  • Tag Along Kid: He was this during the Lab Rats' first mission. Other times, he's had to come along because the situation was desperate.
  • The Team Wannabe: Becomes a part of the team as their mission specialist later on, but still wants more.
    • He got it - in "Bionic Showdown" where he used Donald's exoskeleton to save the others from Marcus, and in "Parallel Universe", where he actually was temporarily given the bionics of the Leo from that universe.
      • Leo's a full member of the team as of the second part of "Rise of the Secret Soldiers".
  • What the Hell, Hero?: In Rise of The Secret Soldiers, he gives this to the Lab Rats when they argue and let fame go to their heads, leading to their downfall.

    Donald Davenport 
Played by: Hal Sparks

  • Abusive Parent: Became a plot point in "The Lab Rats Strike Back". But apart from that he's generally a good man, he just seems have trouble balancing his responsibilities.
  • Action Dad
  • Alliterative Name
  • Badass
    • Badass Bookworm: In Quarantined, Davenport showed that he also has some serious fighting skills - which were actually foreshadowed in Bionic Birthday Fail.
    • Badass Normal
    • Badass In Charge: He's the leader, but he's also pretty competent.
  • Big Good: Just barely. His own inventions have failed at times, and by refusing to take responsibility for his mistakes, it is a stretch to consider him a good person.
    • He is DEFINITELY this after we learn he took his brother's kids when he learns Douglas implanted the bionics (which were meant for robots not humans hence the glitches) and was going to use them as child soldiers for the highest bidder.
  • Bumbling Dad: Bumbling Uncle, technically.
  • Cain and Abel: With his brother, Douglas. He's the Abel to Douglas' Cain. However, if any of Douglas's grievances regarding Donald are of any indication, such as building a cruel robot to beat up Douglas, Donald wasn't much of a nice guy in the past either, even though he was the more responsible one.
  • Catch Phrase: "BOOM!"
  • Cool Uncle: In Concert In a Can, he describes himself more as a fun Uncle. Turns out, this statement is very accurate. Bionic Showdown reveals he's the uncle to Adam, Bree, and Chase.
  • Deadpan Snarker
  • Demoted to Extra: In season 4, he has been appearing in less episodes and Douglas seems to be replacing him. This is quite justified though, as he has Davenport Industries to run, and he needs Douglas to take care of the academy when he's really busy.
  • Embarrassing Nickname: Douglas and Perry call him "Donnie".
  • Expy: He has some similarities to Tony Stark.
  • Good Is Not Nice
  • Fatherly Scientist: He eventually grows into this.
  • Hair-Trigger Temper: He gets angry rather easily.
  • Happily Married: To Tasha.
  • Hypocrite: Donald tells Chase and Adam that as brothers, they need to start respecting each other. Chase however, points out that Donald isn't doing the same with his brother. All Donald comes up with is a poor excuse.
  • Insufferable Genius: He always feels the need to remind everyone that he's a billionaire scientist.
  • In-Series Nickname: Leo usually refers to Davenport as "Big D". However, Leo feels only he has the right To use that nickname.
  • It's All About Me: He doesn't like sharing the spotlight, as he mentioned in Robot Fight Club.
  • Jerkass: Well, usually when he dabbles in his ego. Thing is, he's not very respectful towards others, especially his employees and brother. It's quite easy to see why Douglas went against him in the first place.
    • Jerk with a Heart of Gold: He truthfully loves his family, and when he's able to keep his ego in check is a generally nice guy.
  • Mad Scientist: Under Rule of Funny
  • Man Child: The man's got a bedroom full of video games and action figures.
    • Psychotic Man Child: Especially in "The Lab Rats Strike Back". Also, in Face Off, where he puts Leo and Douglas through sadistic tests.
  • Mission Control
  • Mr. Vice Guy: He's on the good side, and loves his family, but some things do set him off. He can be very selfish at times, he loves himself a bit too much for his own good, is way too inflexible when it comes to being the leader, gets very impatient when he wants something, and enjoys torturing people.
  • Nice Guy: As long as he's keeping his ego and under control.
  • Nephewism: He never told the Lab Rats that their real father is his brother, Douglas, technically making Donald their uncle and Leo their cousin by marriage. But he's also their adoptive father, so...
  • Never My Fault: Happens in several episodes, but special mention goes to Brother Battle. He blames Douglas for upsetting the balance within the team. However, that whole mess could've been avoided if Donald had just done something sooner to help Chase with his problem regarding Adam.
  • Omnidisciplinary Scientist: Donald's a brilliant inventor, engineer, mechanic, theoretical physicist and pretty much every field of science.
  • Pride: Donald thinks too highly of himself, that he can't learn to be pragmatic even in the toughest of situations. His pride ends up becoming problematic in Which Father Knows Best?, when he refuses to accept any help from Douglas, even though he's the one who created Bree's chip in the first place. Donald stubbornly believed he could fix Bree's chip, but Leo knew he wasn't fooling anyone.
  • Skewed Priorities: In Which Father Knows Best?, Bree's chip fix caused her to run without stopping, but Donald was too busy trying to slam Douglas as he always does:
    Donald: Bree, do you mind? The adults are trying to have a conversation here.
  • Took a Level in Jerkass: the Lab Rats Strike Back makes him look like a complete douche.
  • What the Hell, Hero?: While he has been the one giving this to the Lab Rats whenever they start acting selfish, he himself has been on the receiving end of it in several occasions. For example, Chase and his siblings gave him this for being ungrateful when Douglas saved them from Krane, or when Donald kicked Douglas even though he showed promise after fixing Bree's chip. Ironically, even Douglas himself, of all people has given his brother this at least once, such as when Donald yelled at Leo for doing the right thing when things were desperate for Bree.
  • The Worf Effect: Like Douglas, he's good at keeping up with the villains, but often gets defeated due to not being bionic,
  • You're Insane!: He's on the receiving end of this in Face Off with Douglas and Leo. They both got tired of all the painful tests Donald put them through, which leads Douglas to deliver this line to his brother:
    Douglas: At least when Krane gave me electric shocks, he explained why!
  • 0% Approval Rating: It seems no one really likes him, and in Bionic Rebellion, it's shown everyone's usually glad when he's not around.

Recurring Characters

    Tasha Davenport 
Played by: Angel Parker

  • Deadpan Snarker: It's how she usually reacts to the insanity that plays around her.
  • Fake Guest Star: She is a recurring character who appears quite frequently.
  • Happily Married: To Donald.
  • Hot Scoop
  • Kent Brockman News: Her job mostly consists of stories of babies that look like ex-presidents and stuff. The runaway train was her first real assignment according to her.
  • Obnoxious In-Laws: Inverted between her and Donald's brother Douglas. Tasha is mistrustful of Douglas due to him giving Leo bionics.
  • Only Sane Man: Towards Bree and Donald.
  • Parental Favoritism: Tasha is still not set on the Lab Rats living in the house, which is why she tends to show favoritism towards her own son and Bree.
  • Parental Substitute: To the lab rats, but especially to Bree who often comes to Tasha for advice.
  • Sassy Black Woman: Definitely, even though she's the more sane one.
  • Secret Keeper: For the Lab Rats until their secret was exposed to the world. Tasha became this for Leo's bionics until he accidentally revealed them in Rise of The Secret Soldiers.
  • Unfazed Everyman: She eventually grows into this.
  • Women Are Wiser


Voiced by: Will Forte

Played by: Madison Pettis

    Principal Terry Perry 
Played by: Maile Flanagan

  • Abhorrent Admirer: First to Joey Logano, then to Douglas Davenport, as of "You Posted What?!". Apparently, she stuck to the latter.
  • Authority Equals Asskicking: Perry is a principal, but is the toughest authority figure in school, so it's not a good idea to mess with her.
  • Badass Normal: Single-handedly defeated a military robot version of herself, and doesn't even have bionics. Then she has a tendency to survive a lot of punishment. In You Posted What?, it's revealed she has metal implants in her left hip, left shoulder, and skull.
  • Big Bad: In Season 1, as she was the closest to a main antagonist at that time. She becomes a Token Evil Teammate in Season 3.
  • Blackmail: Perry blackmails Donald to pay her when she needs it, or for him to help her with some antics, because It's the only way she will keep their secret. Since the world now knows about their secret, her blackmail is now useless.
  • Bullying a Dragon: She makes the Lab Rats her bionic servants now that she knows their secret.
  • Bunny-Ears Lawyer: Apparenly, the one job she's better at is her job as the Bionic Academy's head of security, even though she's still being Perry along the way. After all, that was the kind of job she's had before becoming principal.
  • Card-Carrying Villain: According to herself, Perry exists to crush people's dreams and ruin their fun. Perry even openly admits to being deceitful and manipulative in Alien Gladiators, and also stealing in Under Siege. Her song, which is a blatant rip off of Canada's national anthem, very much highlights her as this.
  • Cassandra Truth: Just like Leo with Marcus, no one believes her when she knows Sebastian is evil. Given everyone's history with her, it's not hard to understand why they wouldn't believe her.
  • Child Hater: By Unauthorized Mission however, she decides that tormenting kids isn't enjoyable anymore, because Adam, Bree and Chase's absence made her life feel empty.
  • The Dreaded: Leo wants to stay away from her as much as possible, except when real villains threaten him.
  • Drill Sergeant Nasty: Perry gets to be one to Bob to toughen him up, but all she did was tell Bob a few Perry war stories.
  • Drunk with Power: In Bob Zombie, Perry realized that she could register the Bionic Island as a country, and eventually takes ownership. When she does, she goes full-blown egomaniac, acting like a dictator than an administrator. It came to the point where she names the island after herself, puts her face on everything, and stuns (with 15,000 volts) anyone who questions her.
  • Embarrassing First Name/Embarrassing Middle Name: Her full name is Terry Cherry Perry.
  • Enemy Mine: Joins Leo and Douglas against Victor Krane. Basically, she'll help the Lab Rats only if the situation is dangerous enough.
  • Fat Bitch
  • For the Evulz: Her primary motivation for tormenting the students on a daily basis.
  • Friendly Enemy: Perry used to hate the Davenport kids for no reason and considered them the bane of her existence. By Season 3 however, tormenting them specifically was what added meaning to her life. In fact, she admitted to missing the Lab Rats, because life just feels empty without them to make miserable. So basically, she doesn't torment them because she hates them.
  • Freudian Excuse: She's had several of these from her lifetime that are part of the reason she is cruel—kids would make fun of her first and middle name, and she was rejected from several things. In Little Brother, it's implied that most of her problems are because of her mother.
  • The Heavy
  • If I Wanted You Dead...: Says this word per word to Donald in Spike Fright, telling him "If I wanted you gone, I'd have done that a long time ago". She may be a jerk, but she's not entirely horrible.
  • Jerkass: Especially in the first season, though she didn't exactly stop being one.
    • Jerk with a Heart of Gold: A side she mostly shows to Leo. Later on, she shares it with the rest of the Davenports. Sure, she's mean to them, but she genuinely enjoys being around them, and she's still on their side, even if she claims that she only cares about herself. In Space Elevator, Perry claims that she was hard on the Lab Rats because she wanted to toughen them up, and claims she succeeded.
    • Jerkass Fašade: If you heard her talk with Leo in the elevator.
    • Jerk with a Heart of Jerk: Though she does care about the Davenports in one way or another, most of the things she does to help them is for her own selfish causes.
  • Kick the Dog: Now that she knows the Lab Rats' secret, she stepped up her game even further by making them her bionic servants.
  • Lack of Empathy: Admits she only cares about herself, and not about others' feelings.
  • Laser-Guided Karma: She finally gets her comeuppance in Little Brother.
  • Locked in a Room: Twice. First with Leo in Chip Switch, then with Donald in Bionic Rebellion. Keep in mind the people she is locked with DON'T like her.
  • Narcissist: She thinks she's superior to everyone else, and straight out admits that she doesn't care about anyone but herself (though it is revealed later that she doesn't).
  • Nominal Hero: In Season 3 she seems to be shaping up to this.
  • Pet the Dog/Took a Level in Kindness: She actually cared enough to send Leo and Doug to the hospital after Krane and S1's attack. At the end of You Posted What?!, she admits she does care about Leo a little bit. Sure, if a real villain like Krane threatens Leo, of course she wouldn't let her favorite student to torment die.
  • Sadist Teacher: Justified since she was a prison guard.
  • Secret Keeper: As of "No Going Back", but only if Donald pays her and does what she wants when asked. Doesn't work anymore.
  • Shell-Shocked Veteran: Perry fought many battles in her lifetime, even though she never fought with the military, yet it seemed to contribute to her current behavior. If Space Elevator is of any indication, her war stories scarred Bob, implying that she herself is still traumatized by her own experiences.
  • Teeth-Clenched Teamwork: With everyone she's allied with.
  • The Sixth Ranger: She's more or less on the Lab Rats' side now, being more involved in what they do (albeit for her own reasons).
  • Took a Level in Badass: In Spike's Got Talent - she beat down Spike. Case closed.
  • Token Evil Teammate: She's mostly this in Season 3 onward.
  • Tyke Bomb: Her mother advised her to rule with an iron fist.

Played by: Eddie Perino

    Douglas Davenport 
Played by: Jeremy Kent Jackson

  • Anti-Hero: He certainly isn't the most moral fellow even now. However, he does help the Lab Rats in saving the world.
  • Abusive Parents: Played with; he didn't really care about Marcus—he forgot Marcus' birthday and didn't care that Marcus was going to burn out before he reaches his 16th birthday. As for the Lab Rats, he wanted to enslave them and have them commit crimes for him. However, he wanted to make time for family game nights, at least to show he can still make time to be their dad.
  • Afraid of Needles: in a throwaway gag, he reveals that he kicked out of med school because he kept screaming every time he saw needles. Oddly enough, this did not seem to be a problem when he cobbled together a harpoon that has a needle.
  • Axe Crazy: Especially before his Heel-Face Turn.
  • Alliterative Name
  • Ambiguously Evil: Douglas is an example where he gets more ambiguous with each appearance after Bionic Showdown. When he was officially introduced, his agenda was hinted at involving renting out bionic humans to dictators and terrorists, and enslaving Adam, Bree, and Chase for his own evil purposes. Then when discussed in Avalanche, Chase wondered if Douglas was gonna build some bombs, take over a tiny country, steal money from old ladies. Douglas said he could do those things (albeit not in that order), but then he says he just wants to get back at his brother and beat him at something. Then in his next few appearances, every thing he does is to spite him, including blowing up the lab and stealing all of his money. Finally, in ''Which Father Knows Best?", Douglas finds out Bree smashed her chip, and Donald can't fix it, he saw that as another thing he could rub his brother's face in, but Leo reminds him that there are more important things than winning against his brother.
  • Annoying Younger Sibling:...Turned evil. He lets go of this trait after his Heel-Face Turn, and he has to stay on his brother's good side. In the past, he was this, but he had an understandable reason for it.
  • Archnemesis Dad: To Adam, Bree, and Chase.
  • Badass
    • Badass Bookworm: Is just as good a fighter (and a much more brutal one) as his brother and is more intelligent. He got a little rusty later on though.
    • Badass Boast: 'Do you want me to blow up the lab again? I'm good at it
    • Badass Normal
  • Beware the Silly Ones: He's comedic and a bit light hearted. But formerly, he was a cold blooded super villain, who would stop at nothing to achieve his goals and was the most dangerous force they've faced, at least until Krane came along. Now, he fights evil alongside the Lab Rats.
  • Big Damn Heroes: When he saved the Lab Rats from Krane.
  • Big Bad: Of the second Season, but his presence was hinted at by the end of Season 1.
    • Big Bad Duumvirate: Has formed one with Victor Krane ever since he got kicked out of Davenport Industries, but it wasn't apparent until the beginning of Season 3. However Krane goes completely insane, betrays him and tries to kill him. It's later revealed they weren't as tight as thieves either.
  • Butt Monkey: In You Posted What, the jokes were constantly on him.
  • Cain and Abel: With Donald. At this point, it's gotten very petty. Cain to Donald's Abel. This is explored a little further in Brother Battle, and it's revealed that they always tried to beat each other up.
  • Character Development: Douglas goes from a cold-hearted murderer to a noble hero. He even stood up for Leo when Donald got angry at him.
  • Chekhov's Gunman: Douglas is vaguely mentioned in Exoskeleton vs. Grandma, but supposedly as part of a lie for Donald to come up with an explanation. Eventually, Douglas makes his appearance, and everything Donald said to Leo's grandma regarding Douglas turned out to be accurate.
  • Chronic Backstabbing Disorder: Inverted. Two of Douglas's partners betrayed him: Victor Krane attempted to kill him when he was done with him, and Giselle betrayed him by using a movie as a front to eliminate the Lab Rats.
  • Chuck Cunningham Syndrome/What Happened to the Mouse?: He has yet to show up for any of the Bionic Island episodes despite the idea of bionic humans being his to begin with, being Krane's ex-partner, and giving Leo his bionic arm. His absence during the Bionic Island arc is mostly justified, as his knowledge of Krane and bionics would be a Story-Breaker Power and would've resulted in most of the problems occurring in that arc being solved too easily. Of course, he might have been watching over the Lab at Donald's house. He does get a mention in Bionic Rebellion though. Came back in Under Seige.
  • Dangerously Genre Savvy: Upon his second encounter he refused to reveal his evil plan to them, knowing that if he did, then when something went wrong they would use it against him.
    • He also anticipates Krane's betrayal, and fakes his death convincingly enough that Krane doesn't suspect his return to stop him.
  • Deliberately Bad Example: In Season 2, Douglas' main purpose was to contrast with Donald, to show that while Donald can be a jerk to everyone, he means a lot to the kids, whereas Douglas was very ruthless to the point that he would use bionic humans as weapons.
  • Diabolical Mastermind: Able to create bionic humans and high tech gear. Unfortunately, it fell in the wrong hands.
  • Didn't Think This Through: Douglas didn't think Leo needed a capsule because only his arm is bionic. Leo's arm act up because it hadn't been calibrated to his nervous system.
  • Dude, Where's My Respect?: Douglas just doesn't get enough respect. The President just says he's "the help".
  • Enemy Mine: He is fed up with Victor Krane after being betrayed by him and teams up with the Lab Rats in Taken. Afterwards, he truly joins the Lab Rats.
    • This happens again in Which Father Knows Best?, where Leo had to find Douglas, because he was the only one who could restore Bree's bionics.
  • Envy: Towards his older brother Donald. Is implied to be at least partially responsible for him turning evil.
    • He overcomes this after his Heel-Face Turn, though he still slips into this every now and then, and all he's been trying to do is stay on Donald's good side.
  • Even Evil Has Standards: When his plan to control Adam, Bree, and Chase with the Triton App fails, he claims he can update the Triton App, and his business partner Victor Krane tells him to use it to destroy them. Douglas says destroying the Lab Rats was never part of his plan. Krane tells him they're using his plan now and leaves. Douglas has a reluctant look on his face. Douglas later reemphasized that hurting Adam, Bree and Chase wasn't among his intentions, but Leo was fair game to him, hence why he ordered Marcus to murder him. In addition, his statement of not wanting to hurt them becomes questionable, as it's later revealed he tried to kill the Lab Rats 522 times.
    • It's also revealed in Rise of The Secret Soldiers that when he designed their chips, they have a protocol that will allow them to fuse their bionics as a weapon of last resort. However, he didn't tell them because the results would be catastrophic. It's clear now that he NEVER wanted to kill them in the first place.
    • In One of Us, it's revealed Victor Krane wanted to put a doomsday virus in the Triton App. Douglas refused, but Krane added it anyways when he upgraded the Triton App.
  • Evil Genius
  • Evil Step-Uncle: To Leo, who was a thorn on his side. Leo jokingly lampshades this in Face Off. He's no longer evil, though.
  • Faking the Dead: He's really good at doing this. He was presumed dead prior to the start of the series.
  • Faux Affably Evil: Douglas may be cheerful and seeming friendly, but underneath it all he's cold blooded and ruthless, case point him suggesting they (he Adam, Bree and Chase) plan family game night while working to enslave them.
    • Switches to Affably Evil in Season 3, and the evil part is gone (mostly) after Sink or Swim.
  • Forgiven, but Not Forgotten: While his family has accepted him, the things he did while he was evil are almost always brought up. Douglas still has a long way to go in earning everyone's trust, and he does so by making himself useful. Of course, he is in enough trouble with Donald as it is, and Douglas does his best to get back on his good side.
  • Greater Scope Villain: Douglas's actions had a strong influence on every bionic-related incident that had occurred throughout the series, as it was his idea to implant bionics into human beings. He gave Krane bionic abilities as well as technology and research, which led Krane to become a power-hungry, psycopathic mastermind. In addition, Douglas giving Krane his technology led Krane to go behind his back and genetically engineer bionic soldiers. Douglas is also indirectly responsible for Giselle, who was his ex-girlfriend and he gave her his research on androids.
  • Heel-Face Turn: Following Krane deciding he wants to kill Adam, Bree and Chase he begins to have second thoughts. Then as Krane gets more and more insane he starts to drift away and actually turns on him, saving Adam, Bree and Chase. However he truly redeems himself when he builds Bree and new chip and actually agrees to work with Donald to save her when it malfunctions. After some prompting Donald agree's to give him a second chance.
    • Cemented in "You Posted What" where he's now fully joins the others, though he might have committed a few felonies afterwards if Brother Battle is any indication. However, it was most likely in a playful intention. Nonetheless, all the things he did during his evil days come back to bite him as the series goes on.
  • Heroic Comedic Sociopath: In You Posted What?, he suggested that he could blow up the lab just to get rid of all the agents looking for them. However, the intention was more to get away than to kill them, seeing as he had panicked. Falls into this a lot after switching sides.
  • Human Popsicle: Gets frozen solid by his brother's new freeze ray after Chase tricked him.
  • Insufferable Genius
  • It's All About Me: Though it's because Donald's the one one-upping him and getting all the attention.
  • Just a Machine: He's pretty indifferent, almost amused by the fact that his son is going to die before turning 16 because Marcus is 'just an android'.
  • Knight of Cerebus: He was much darker than most of the shows other villains, and most Disney villains in general. Although still portrayed as somewhat light hearted, he is a realistic mad scientist, who's engaged in experimenting on children, has no problems committing outright murder (even to his own family) and before redeeming himself, his long term goal was a mixture of brainwashing, slavery and Child Soldiers.
    • Even after his Heel-Face Turn, while now a good guy, he still casually and (mostly) shamelessly admits to having committed countless crimes.
  • Lack of Empathy: Douglas has trouble grasping the concept of empathy, back when he was a villain this made him incredibly dangerous. Even after his Heel-Face Turn, he still seems to have trouble with it outside his own family, such as describing potential horrific effects or even deaths in a way that always relates to himself.
  • Laughably Evil: Sure, he's threatening...but he's also just as crazy as Donald is. He even posted hilarious updates that Adam has been reading. His jokes however, are terrible.
  • Luke, I Am Your Father: He's the one who created Adam, Bree, and Chase. So yes, he is their real father, which means everything Donald said in Exoskeleton vs. Grandma was accurate all along.
  • Mad Scientist: An interesting example, rather than being a stereotypical mad scientist. Douglas is instead presented as someone who is closer to realistically dangerously insane, and is also a super genius scientist. Of course, there's also the fact that he has trouble making an invention that won't end with someone getting hurt. It's also said that he turned his brother's dead gerbil into a zombie.
    • In "Spider Island" he reveals that before he went into technology he tried to bring extinct species of animals back from the dead. However he never cracked it.
  • Mr. Vice Guy: Despite his Insufferable Genius traits and somewhat psychotic behaviour, he's otherwise a pretty nice guy.
  • Morally Ambiguous Doctorate: He never got one, because he failed.
  • Omnidisciplinary Scientist: Just like his brother, Douglas is a specialist in bionics, engineering, genetics and a whole lot more.
  • Only Sane Man: He shares this trope with Chase. Unlike Donald, Douglas has matured after his Heel-Face Turn, though he doesn't always play by the rules.
  • Pet the Dog: Quite literally. The one being he actually cared for after being kicked out from Davenport Industries was his pet dog, Otis. Chase and co. are surprised that a bad guy like Douglas actually had someone he cared for.
  • Punch Clock Villain: Even back when he was a villain, Douglas was still an all-around fun guy. He even shared a few jokes with Donald and the Lab Rats. This goes to the point where he suggested that he would plan family game night to show them that he can still be their dad, while enslaving them.
  • Psychotic Man Child
  • Shadow Archetype: To Donald. Donald may have been an arrogant jerk who doesn't always treat Leo or the Lab Rats with proper respect, but he at least tries to keep it in check. Douglas on the other hand is far worse—he is basically Donald if the latter did not keep his arrogance and pride in check.
  • The Sociopath: He was this back when he was a villain, though after his Heel-Face Turn he is more stable.
  • We Can Rule Together: Tries this with Chase. It backfires horribly.
  • Tragic Villain: "Avalanche" showed him being one. It is also the reason he was able to do a Heel-Face Turn.
  • The Worf Effect: Though he's very good at keeping up against Krane and other bionic villains, he sometimes falls into this, mostly to have the Lab Rats save the day.
  • Throw the Dog a Bone: Donald doesn't trust Douglas to be a part of Davenport Industries again, but he does let Douglas take care of the Academy when he can't be around.
  • Would Hurt a Child: Not his own, but Leo was fair game because he kept interfering with his plans.


    Marcus Davenport 
Played by: Mateus Ward

    Victor Krane 
Played by: Graham Shields

  • Ax-Crazy: Due to his stoicism its not so obvious, but really the guy loves destruction
  • Badass: Incredibly powerful and dangerous, able to take all the heroes on at once. It took a Dangerous Forbidden Technique combining all three of their powers to stop him.
  • Bald of Evil
  • Beard of Evil: In his first appearance, he's shaved it off by his second, but its back by "You Posted What".
  • Body Horror: The right side of his face has some scars due to implanting some bionics into his body.
  • Cut Lex Luthor a Check: Despite his intelligence, this guy has never won anything.
  • Corrupt Corporate Executive: Paid Douglas a huge sum of money so he could become bionic and has no problem injuring the Lab Rats or having them brainwashed and hurting other people.
  • Crazy-Prepared:
    • Krane knew Douglas would go into hiding, so after Douglas turned on him, Krane tampered with the bionics of Douglas's pet dog Otis, so that Otis could track down Douglas and eliminate him. Even if Krane is gone, Otis still had Krane's directive.
    • Krane also installed a doomsday virus when he upgraded the Triton App, so that if something happens to him the virus would trigger after a certain period of time and cause the soldiers to self-destruct. Doing so would prevent anyone else from controlling them.
  • Energy Absorption: He can absorb energy from anything.]]
  • Evil Genius: An evil genius bent on world domination. He even creates software that would take even Douglas months to decrypt.
  • Evil Is Bigger: He's much taller than Douglas, likewise he's more evil as well.
  • Evil Is Petty: Krane is an egomaniac with a bid for world domination, but he went out of his way to be a jerk to Douglas, such as not going on vacation to the Florida Keys, even though he said he would. He would also threaten to kill Douglas if Douglas kept doing impressions of him at dinner parties.
  • Eviler Than Thou: He's this to Douglas, and decides that Douglas's plan is too weak.
  • Evil Wears Black
  • Greater Scope Villain: Victor Krane is said to be the ultimate, "all around bad guy" Douglas has ever known. Krane is Douglas's secret benefactor ever since the latter got kicked out of Davenport Industries. Krane gave Douglas a lot of money to continue his evil plans, provided Douglas can give Krane his bionic research. When he revealed the Lab Rats' secret, he's indirectly responsible for Giselle becoming obsessed with destroying the Lab Rats and bionic soldiers.
  • It's All About Me: To frightening levels, Krane's egomania is to the point he rigged all his soldiers so they would die, if something happened to him. Him taking on the heroes is partially down to being unable to except anyone else having powers similar to his, outside of his own control.
  • Knight of Cerebus: Frighteningly serious with deadly powers and is considered Eviler Than Thou when compared to Douglas.
  • Lack of Empathy: Complete and utter lack that is, the rights and even lives of anyone but Krane, is not even a blip on his radar.
  • Mind over Matter: One of his powers, he tries to use it to strangle Douglas.
  • Shock and Awe: Douglas gave him the power to shoot electricity from his hands.
  • The Stoic: He's not really the joking type which makes him contrast drastically with Douglas whenever they interact. When he interacts with Douglas during You Posted What?!?, he's more Faux Affably Evil.
  • The Social Darwinist: By "Rise of The Super Soldiers" Krane now believes being Bionic makes you superior to normal people, and plans to create a bionic empire with himself as the dictator.
  • The Sociopath: His lack of empathy and disregard for human life disgusts Douglas. He possesses no sympathy, guilt or remorse and will gladly murder anyone who gets in his way.
  • Super Strength: Douglas empowered him with Super strength.
  • Taking You with Me: He reprogrammed the Triton App, so that if something happened to him, after a while all his Bionic soldiers would die also. However, since the Lab Rats also had the Triton App, that means he takes his enemies with him too.
  • With Great Power Comes Great Insanity: Implanting himself with more bionics has driven him completely insane.

    Giselle Vickers 

  • Big Bad: Seems to have this role in Season 4, and she wants to create androids to eliminate all bionic superhumans. Her androids now lie in pieces, but now she wants to repair and rebuild Marcus.
  • Corrupt Corporate Executive: Was in the film industry and the robotics industry. She likewise is unrealistically ruthless in both areas.
  • Dark Action Girl: Is pretty good in a fight.
  • Dirty Coward: Sure she's high and mighty when she's in control, but just watch her crumble when she looses the upper hand.
  • Distaff Counterpart: She's this to Douglas (back when he was evil).
  • Evil Former Friend: Also an evil former Girlfriend to Douglas. Apparently she became evil long after Douglas did.
  • Evil Genius: Even Douglas admits that her androids are sophisticated beyond what he is capable of, which greatly angers him.
  • Faux Affably Evil: Happy to turn on the charm, until she gets what she wants.
  • Genre Blind: Really shouldn't have told Troy he was outdated, and going to be replaced by her new brand of androids.
  • Greed: Her main motivation for wanting to wipe out the bionic heroes? So that her androids don't have any competition.
  • Hot Scientist: She's pretty easy on the eyes for a selfish murderer.
  • Lack of Empathy: Concepts such as empathy, don't even seem to register with her. The only time she shows any care for another person, its purely manipulative.
  • Older Than They Look: Is about Douglas's age, but could pass for being younger.
  • Pride: Is pretty arrogant, she for instance considers her android technology superior to bionics, despite admitting to failing to figure out Chase's abilities.
  • Smug Snake: Really as dangerous as she is, she's a bit to full of herself for her own good.
  • The Sociopath: Like Victor Krane, she has no regard for human life and will gladly murder anyone who gets in her way.

Troy West

Played by: Leo Howard

  • A.I. Is a Crapshoot: Because Giselle mistreated him he decides to turn on her and eliminate ALL humans.
  • Badass: Is a very powerful Android, able to give Chase and Adam trouble.
  • The Dragon: To Giselle. Out of all the Androids he appears to be the only one that's completely sentient and is her right hand.
  • Dragon Ascendant: Becomes this in the climax of Bionic Action Hero.
  • Eviler Than Thou: Invokes this after betraying Giselle by stating that he won't just wipe out bionic humans, but all humans.
  • Faux Affably Evil: Just like his creator, he happily turns on the charm when he wants something.
  • Logical Weakness: Due to being made of metal, he is venerable to Chase's Magnetism App.
  • Kill All Humans: What he graduates to in the end, sick of Giselle's mistreatment he plans to take over the android army and exterminate all the humans.
  • Kill It with Water: Unlike Giselle's later generation robots, Troy is not waterproof. This is how Bree destroys him.
  • Mistreatment-Induced Betrayal: Was completely loyal to Giselle, until she revealed her plans to scrap him.
  • Robotic Psychopath
  • Super Strength
  • The Starscream: Near the end of the episode he turns on Giselle in retaliation for her mistreatment towards him and plan to replace him once she obtained her updated Android army. He blasts her, and declares that he will become the new leader of the Android army.

Bionic Soldiers

    In General 

  • Amnesiacs Are Innocent: All the soldiers were blank slates after being free from the Triton App, but not only do they not remember anything they did while controlled by the Triton App, they didn't even have lives before the Triton App woke them. Unfortunately, assuming this proved to be a mistake for Chase when it came to Sebastian, who turned evil after the former told him about Krane and what happened. When it turned out S-1 survived and came to the island, Chase did not want to take any chances with this trope, remembering what happened with Sebastian. However, Chase ends up being proven wrong again when it turns out she is scared and really did need help.
  • Brainwashed and Crazy: They were all mind-controlled by the Triton App, and did Victor Krane's bidding without even a thought. Once they are free from the Triton App, they have no memory of ANYTHING, period.
  • Decapitated Army: Once Krane is shot in the sky, the soldiers all cease to function without the Triton App controller and drop like flies.
  • Forced Into Evil: They never experienced real life before the Triton App. Under the Triton App, they were forced to do evil things like steal government property and threaten to eliminate humankind.
  • Massive Numbered Siblings: There are at least a hundred of them, and they're brothers and sisters to each other.
  • Mauve Shirt: After joining the Davenport Bionic Academy, all of them are recurring background characters, but only a handful of them have characterization limited to the episode they appear in, namely Lexi, Tank and Kate.
  • Redshirt Army: They get knocked out with zero effort when Giselle's one android comes. This is quite justified as most of them are still in training.
  • Slave Mooks: While serving Victor Krane, they were all mindless slaves who only did what they did because of Douglas's Triton App.
  • Super Soldier: They are genetically engineered with various bionic abilities. Douglas later discovered they have hidden abilities.
  • Why Am I Ticking?: Douglas ran a scan on S-1's chip and discovered that Krane installed a doomsday virus in their Triton Apps. If the soldiers are without their controller for six months, they will self-destruct.
  • You Are Number Six: All the solders had numbers instead of names (S-1, S-3, S-12, etc). Upon entering the Davenport Bionic Academy, they had to discard their soldier numbers and adopt names to symbolize that they are no longer soldiers. About 40 percent of them have a Donald-based name, but the rest of them have different names. So far, S-1 is the only one without a name.

    S- 1 
Played by: Ashley Argota

  • Arch-Enemy: To Leo. In One of Us, they do become friends.
  • Broken Bird: In truth, S-1 is nothing more than an innocent, naive teenage girl whom Krane tortured and experimented on and forced her to do evil via the Triton App. After Leo defeated her and the Triton App was deactivated, S-1 experienced painful flashbacks about Krane due to a glitch, which left her scared and vulnerable with no one to turn to, until she ran into her former enemies.
  • Co-Dragons: Implied to have been this with Sebastian. However, she turns good while Sebastian turns evil.
  • Dark Action Girl: Is pretty tough in a fight, and was Krane's lieutenant.
  • The Dragon: To Krane, and she was chosen as his lead soldier.
  • Distaff Counterpart: To Marcus.
  • Heel-Face Turn: After Krane's defeat, she, like the other soldiers, lost her memory and she woke up in a field. A family took her in but freaked out when she was revealed to be bionic. So she made her way to the bionic island in hopes they could help her, and was truly scared and alone. After the heroes find out about and thwart Krane's contingency plan from her, they decide to give her a second chance with the others. Unlike her brother Sebastian, she seems to accept that Krane was a sociopath, presumably down to actually seeing him (through painful flashbacks) rather than hearing second hand.
  • Mook Lieutenant: Despite being Krane's lead soldier, S-1 never was anything more than another slave to him.
  • Suspiciously Similar Substitute: She's basically a replacement for Marcus—having all the Lab Rats' abilities, being the Big Bad's lapdog, and mostly targets Leo.
  • Uncertain Doom: Last she's seen, Leo uses his energy transference ability, and blasts her in the sky. It remains unclear whether she survived, but Leo thinks he finished her. However One of Us reveals she survived, and came off a scared girl with no memory of what happened, and painful flashbacks of Victor Krane.

    Sebastian/S- 3 
Played by: Cole Ewing

  • Arc Villain: From Unauthorized Mission until Bionic Rebellion.
  • Avenging the Villain: After he finds out the Lab Rats have supposedly killed his father Krane, he decides to follow in Krane's footsteps and kill them. Sadly he would never come to understand how terrible Krane was.
  • Badass: Was the best student at Bionic Academy, he's even able to take Chase on.
  • Brainwashed and Crazy: Sebastian was a bionic soldier who was controlled by Krane's Triton App. After the Triton App deactivated, he did not remember ever fighting Chase.
  • Broken Pedestal: To Chase, Sebastian was one of the best students who had great potential to be a hero. However, Sebastian betrayed him, after everything he did to keep him safe. Even the other soldiers accept that what Sebastian did was wrong.
  • Dragon Ascendant: He was the leader of Victor Krane's bionic soldiers in Rise of The Secret Soldiers. In Bionic Rebellion, he decides to avenge Krane's death and continue his evil plans.
  • Evil Counterpart: Is Chase's, they both possess a variety of abilities, both serve as leader for their group, both are very intelligent and both are incredibly loyal to their fathers. However as Sebastian's father is Victor Krane, this creates a problem as he refuses to believe that Krane was far from a father.
  • Face-Heel Turn: At the end of Unauthorized Mission, Chase tells him about Victor Krane and his agenda. Unfortunately, he didn't take it well, and decided to betray him by avenging Krane and taking out Davenport.
  • Manipulative Bastard: While pretending to be good, he was able to use charm and his friendship to manipulate the others, especially Chase into furthering his plan.
  • Nice Guy: At first, Sebastian is friendly caring and supportive, especially towards his bionic siblings unfortunately it doesn't last. In the end, he tried to control them like Krane did. In any case though, he's a colossal jerk to Chase because he's a fun-killer.
  • Revenge: Tries to kill Donald, in response to the others killing Krane.
  • The Rival: He and Chase do not get along at all.
  • Sanity Slippage: Its clear that learning the truth didn't bode well for his sanity. He goes from a genuinely nice guy, to a revenge obsessed megalomaniac.
  • The Social Darwinist: Adopts Krane's philosophy that Bionic beings are superior.

Played by: Max Charles

  • Everything's Better with Spinning: His main bionic ability is that he can spin like a tornado.
  • The Rival: Starts out as this to Leo, but they try to get along in later episodes.
  • The Team Wannabe: Just like Leo when he was younger, Spin wants prove himself a hero and go on missions. However, he ends up making the same mistakes Leo did and disobeying Davenport.
  • Those Two Guys: With his brother, Bob.

Played by: Brandon Salgado-Telis

  • The Ditz: Is really not that bright, its one of the reasons he and Adam get along so well.
  • Ironic Fear: Bob is acrophobic, even though he can levitate.
  • Literal-Minded: Bob takes a lot of rhetorical statements and expressions too literally, especially when Adam said "Let's do things we're gonna regret".
  • Little Boy Seeks Big Girl: Bob has eyes for Bree.
  • Plucky Comic Relief: He and Spin are usually around for comic relief in the show.
  • Super Strength: One of his bionic powers, as he was able to lift weights that were at least 100 pounds.
  • Those Two Guys: With his brother Spin.
