Main Characters

Introduced in Lab Rats

Chase Davenport

Played by: Billy Unger (billed as William Brent in Elite Force)

• Anti-Hero: He's noble and responsible, but it's hard to deny that he's also pretty rude and arrogant.
• Academic Alpha Bastard: He wants things done his way, not anyone else's.
  Adam: Don't be like Chase!
• Arbitrary Skepticism: Chase doesn't get the concept of superpowers despite being a bionic superhuman. This is understandable, because bionic abilities are derived from technology while superpowers are a phenomenon that defy reason.
• Badass Armfold: See the folder image.
• Badass Bookworm: Like his siblings, Chase is trained in martial arts.
• Barrier Warrior: Chase can create forcefields around himself. As the show progresses, its design changes from a solid blue orb to a transparent half-circle.
• Beauty, Brains, and Brawn: The Brains to Adam's Brawn and Bree's Beauty.
• Berserk Button:
  • Don't say you're smarter than he is. Sebastian learned that the hard way. That goes for you too, Donald.
  • He also doesn't like it when Bree flirts with another boy, though this seems to be averted with Oliver.
  Chase: (to Sebastian after he flirts with Bree) Don't EVER say that again!
• Brainy Brunet: Has brown hair and the bionic power of Super-Intelligence.
• Butt-Monkey: He's always picked on for his inability to get girls or for being short. By Elite Force, he gets more respect, but at Oliver's expense.
• Chronic Backstabbing Disorder: Inverted. Almost everyone who's ever wanted to be his friend has ended up having ulterior motives, which is a major factor in his inferiority complex. Marcus was working for Douglas, Sebastian was planning a rebellion and needed access to passwords and his chip schematics, and Reese just needed to get to Mission Control to download the superhero list. These are basically all of the people he's ever been friends with who weren't on a mission team with him.
• Competition Freak: He'll jump into any contest that can prove his superiority, and isn't afraid to cheat to win.
• Control Freak: Lampshaded by Bree in "Unauthorized Mission". The spinoff reveals why he's like this: being mission leader was always a part of him, and it was something that he didn't want to lose. After being rescued by Kaz, Oliver and Bree, and thinking about Skylar's performance in her first mission in a long time, he abolishes the Mission Leader title.
• Deadpan Snarker: He and Leo are the master snarkers of the show.
• The Dog Bites Back: Chase finally makes a name for himself in "The Jet Wing" by shoving Adam to the floor as long-awaited punishment for punching him one too many times, much to everyone's shock and Adam's dismay.
• Enraged by Idiocy: Especially in Season 3 and 4, and in the spinoff.
• Et Tu, Brute?: Chase was greatly hurt when Sebastian betrayed him. In One of Us, he refused to trust S-1/Taylor on the grounds that she might do the same, showing just how badly Sebastian wounded him.
• Flanderization: He changes from a Control Freak with a heart of gold to a perfectionist in the later episodes of Bionic Island.
• Foolish Sibling, Responsible Sibling: The Responsible to Adam, Bree, and Leo's Foolish.
• For Science!: In "Spike vs. Spikette", he intentionally activated Kate's commando app (despite Douglas explicitly telling him not to), so he could see the app work from the outside.
• Four-Temperament Ensemble: Chase cycles through all of these at some point. He starts out as Sanguine, but as his confidence levels go way, way down, he becomes Melancholic. In late Bionic Island, he becomes an awful, arrogant version of Choleric and stays this way for the beginning of Elite Force, but after he abolishes the Mission Leader title he gets much, much kinder and goes to Phlegmatic.
• The Friend Nobody Likes: Due to his Type A personality and being an Insufferable Genius, people don't seem to like him.
  Bree: And you wonder why no one at school likes you.
• Hair-Trigger Temper: Do NOT piss this guy off. When his temper gets driven high, he will become Spike.
• The Hero: Seems to share the role with Leo. They're also the same age.
• Hero Antagonist: In "Zip It," he destroyed Bree's only chance of having a job as a normal teenager.
• Insufferable Genius: Never misses an opportunity to remind others that he's the "smartest man on Earth".
• Jerkass Teenage Son: Shows this often in the later episodes of Bionic Island. Bree is much worse than he is though, at least at the beginning.
• Laser Blade: Obtains a "laser bo" in Brother Battle, a laser staff generated from his hand.
• The Leader: Chase has been designated mission leader since he was 12. In Lab Rats: Elite Force, Chase later sees how much his other team members were able to step up and abolishes the position of Mission Leader altogether.
• Like Father, Like Son: He's similar to his adoptive father (really biological uncle) Donald, as both are snarky InsufferableGeniuses. A straighter example is him and his actual father, Douglas. Both were picked on by their older brothers, and seek recognition in spite of feeling overshadowed.
• Mind over Matter: Called 'molecularkinesis', it's one of Chase's hidden bionic abilities.
• Mr. Fanservice: Although he doesn't have a shirtless scene, his shirt is often unbuttoned a little lower than is necessary, especially in later seasons.
• My Sister Is Off-Limits: Every time Sebastian hits on Bree, he always yells at him for it. If Bob does it, however, he finds it hilarious, most likely because he knows Bob stands no chance with Bree and just enjoys watching her get annoyed.
• Nerds Are Sexy: Billy Unger has a lot of fangirls. In-universe however, girls almost never ask Chase out. One episode of Elite Force features him making a series of attempts at creating a robot girlfriend and all of them preferring Kaz. However, in "Spike Fright" Sabrina expresses interest in going out with him, and Caitlin had a crush on him.
• Never My Fault: In keeping with his Insufferable Genius traits, Chase hardly ever admits to making mistakes, instead blaming others for not following his orders correctly. When he does make a mistake and actually owns up to it, it stays with him (as seen with Sebastian’s betrayal leading him to be distrusting of S-1.)
• Nice Job Breaking It, Hero: When he tells Sebastian the truth about Krane being killed off in Unauthorized Mission, it causes Sebastian to start a rebellion. Almost the entire season four premiere was itself a Nice Job Breaking It, Hero moment for Chase, to the point where Adam says "It was all Chase's fault".
• Not Quite Flight: In "Bionic Showdown", Chase reveals that he has a second hidden bionic ability - the power to levitate himself.
• No Indoor Voice: He has a tendency to yell a lot, especially when he states things matter-of-factly or overreacts.
• No Social Skills: More so than Adam and Bree. Chase just can't understand what other people would like. In "Smart and Smarter," his attempts to gain favor for the "Student of the Semester" award involved such things as a device that berated his classmates for their choice of lunch, or having a student put into detention for being just a little late on the grounds that the student would thank him for "putting him on the right path".
• Only Sane Man: Between Adam and Leo joking around, Bree being the Bratty Teenage Daughter, and Donald being unmistakably crazy, Chase definitely shares this trope with Douglas (even though Douglas himself 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' favorite too.
• Personality Blood Types: Type A. He is bossy, controlling and a workaholic.
• Properly Paranoid: Chase has become more cautious in Elite Force, so he falls victim to the Idiot Ball much less. After Kaz introduces the Superhero Communications Network to him, Chase makes it a point not to visit any superheroes, because someone could be watching. He's right—Skylar visits Crossbow and leads Roman right to her.
• Red Oni, Blue Oni: The Red to Adam, Bree, and Kaz's Blue.
• Relationship Sabotage:
  • Before Sebastian turned evil, Chase tried to ruin his constant flirting with Bree. To be fair, any brother would feel this way about his sister.
  • Oliver accuses Chase of doing this to him and Skylar.
• Savvy Guy, Energetic Girl: The Savvy Guy to Bree's Energetic Girl.
• Shorter Means Smarter: But don't emphasize the "short" part, it's a source of angst for him.
• Smug Snake: At times.
• 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.
• 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 somewhat above average intelligence, and only a rough idea of how to solve problems.
• Took a Level in Jerkass: Not by much compared to Adam, but he became more egotistical and cocky in later seasons. This was changed in Elite Force, where he Took a Level in Kindness in comparison to Bionic Island.
• 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. It's later subverted because we find out he is not the youngest.

Spike

Played by: Billy Unger

• Artificial Human: Created as the counterpart of Chase.
• The Big Guy: Spike loves to break stuff. He can break anything with his head and it doesn't even hurt.
• The Brute: Indeed.
• Deadpan Snarker: Occasionally.
• Everyone Has Standards: He called Principal Perry out for not helping her team.
• Evil Counterpart: OK, maybe not evil, but he is a more brutal and crude version of Chase.
• Good Is Not Nice: Douglas created him to help Chase in emergency situations.
• Hair-Trigger Temper: He's easily angered.
• Hot-Blooded: You simply can't calm Spike down. As Donald once said, "He's like a wild animal. All you can do is wait for the threat to pass or defeat him in battle."
• Jerkass: Spike has a sadistic and mean sense of humor.
• Knight in Sour Armor: Despite the fact that Spike was meant to help the Lab Rats, he possesses a very hostile and argumentative attitude (but in a humorous way of course).
• Made of Iron: As long as he's not fighting Principal Perry.
• Noble Demon: He is loyal to those who get on his good side.
• One-Man Army: Strong enough to beat up a group of Jerk Jock bullies like it's nothing.
• Super-Strength: Which he uses to break stuff.
• Wouldn't Hit a Girl: When Kate's Commando App causes her to go on an endless rampage of destruction, Spike is activated with the intent of fighting her to a standstill, but he claims he doesn't fight girls. Then he joins her.

Adam Davenport

Played by: Spencer Boldman

• Aesop Amnesia: Notably averted by Season 4. In Adam Steps Up, he didn't take his position as a mentor seriously, but learned his lesson. In Simulation Manipulation, he takes his job more seriously and notices Chase might have been using his students to cheat.
• Beauty, Brains, and Brawn: The Brawn to Bree's Beauty and Chase's Brains.
• Beware the Silly Ones: His huge concern for safety after a dislocation was an even bigger liability than his usual silliness.
• Big Brother Bully: Has moments of this, mainly towards Chase.
• Big Brother Instinct: Despite the above, Adam ultimately cares for his siblings, and the possibility of them getting hurt is a major Berserk Button for him. He stands up for Bree and Chase when they're bullied by other kids in early episodes, and in "Parallel Universe" he was quick to push them behind him after being told that Donald's new device could gravely injure them. In "Taken," he beats the crap out of Krane after the latter throws a fireball at Bree.
  • As Leo's step-brother, he is very kind to him and plays with him a lot. Just like his biological siblings, he cares about Leo and will stand up for him as often as possible.
• The Big Guy
• Blow You Away: Gains "pressurized lung capacity" in Brother Battle, the ability to unleash a massive gust of wind from his mouth.
• Bunny-Ears Lawyer: Turns out Adam has become a much better mentor around Season 4, even with his low intelligence. What makes him a more effective mentor is that he motivates his students — unfortunately, this happens to be at Chase's expense.
• Casanova Wannabe: He claims he can get girls better than Chase, but he's just as bad as he is at getting girls. Although...
• Chick Magnet: Being six-foot-tall and built like a brick house, he does have a few girls fawning over him, including Danielle in Leo's Jam and Abhorrent Admirer Caitlin in Robot Fight Club.
• Cool Teacher: For the students at the Bionic Academy. He treats the students he mentors like friends, encouraging and guiding them.
• Crouching Moron, Hidden Badass: He usually has no idea what's going on, even if it's something simple to understand, but he is still the strongest Lab Rat.
  • It's only when his family is in danger that his inner Badass truly comes out. The most noteworthy example of this can be seen in Bionic Showdown, when he destroys Marcus with simply one Kamehame Hadoken attack to save Leo.
• Did You Just Punch Out Cthulhu?: In the crossover episode with Mighty Med, he accidentally takes out The Crusher, a superhero deemed the World's Strongest Man.
• Disappointing Older Sibling: Due to his stupidity and recklessness.
• Dumb Muscle: He does become aware about this later on.
• Dumbass Has a Point: This comes more and more into play as Season Two progresses.
• Eye Beams: Has this power whenever he gets very angry (although he learns to control it in later seasons).
• Flanderization: His Big Brother Bully tendencies gradually increase throughout the series, to the point where he can barely go one scene without insulting or hitting Chase.
• Foolish Sibling, Responsible Sibling: The Foolish to Chase, Bree, and sometimes Leo's Responsible. When Adam does start to act more responsible in terms of safety, it develops into paranoia and creates a lot more problems for the team than those that result from his usual carelessness.
• The Fool: He jokes around at the most inappropriate times.
• Gentle Giant: Adam is portrayed by Spencer Boldman, who is the tallest of the entire Lab Rats cast (and of the entire Disney XD line-up of teen actors circa 2012, as seen here) at 6'2" (6'1" at the time). Adam may dwarf everyone with his height, but doesn't deliberately harm anyone except Chase. He is very careless, though, which sometimes leads to others accidentally getting hurt.
• Hand Blast: Has this power whenever he gets very excited, afraid or angry.
• Hidden Depths: While not possessing Obfuscating Stupidity by any means, Adam is occasionally far more clever than anyone gives him credit for.
  • Season Two has shown his character definitely moving in this direction, as his interrogation by Principal Perry allowed him to fool her completely and get them off the hook for his slip-about 'going on missions', give Bree and Chase a well-deserved scare by mimicking each of their powers, as if he's showing exactly what they can do, prove that he can keep the family secret... and get Leo back for snarking off when they got detention.
• Horrible Judge of Character: He has a problem with this, especially with Douglas. He also flirts with S-1, an evil bionic soldier.
• Jerkass: Can be this to his siblings quite frequently, especially Chase, whom he thinks it's funny to punch.
• Jerk with a Heart of Gold: He can be an egotistical Big Brother Bully at times, but he really does care about his siblings, and is ready to make up for his mistakes when he's realizes he's crossed a line.
• Jerkass Realization: In Spike Fright, when his envy gets the best of him and results in him ruining Chase's chance of having a girlfriend, Adam started taking action for his responsibilities for once, and saved their relationship.
• Kamehame Hadoken: Adam's hidden bionic ability. Referred to as the "blast wave," it's powerful enough to instantly drop superpowered androids with one shot and does enough collateral damage to collapse hidden underground lairs.
• Literal-Minded: One of the ways his stupidity manifests itself.
  Chase: Bree, how fast can you subdue the crew?
  Bree: Look who you’re talking to. “Fast” is my middle name.
  Adam: Lucky. Mine's "Charles".
• Malaproper: Another tendency of his, which gives us such gems as "You're a total hypnotist!" and "It was very scrumptious of your part".
• Meaningful Name: It's no coincidence that Adam, the world's first bionic superhuman, shares his name with the first human being created by God. His middle name, Charles, could be a reference to famous 20th century bodybuilder Charles Atlas, fitting for someone endowed with Super-Strength.
• Mr. Fanservice:
  • In general, he's occasionally seen wearing tight-fitting or sleeveless tops that bring out his musculature.
  • He spends most of the episode Dude, Where's My Lab? with his arms bare, and when Leo takes advantage of the siblings' bionic abilities to earn them the money they need, Adam steps up and starts flexing.
  • At the start of Leo vs. Evil, as he's about to arm-wrestle Chase, he brags about his biceps and starts kissing them, much to Chase's annoyance.
  • In My Little Brother, when he shrinks, his clothes don't, leaving him naked (and visibly annoyed over it) inside his shoe.
  • Perhaps the most notable fanservice moment for Adam comes in Rise of the Secret Soldiers, in which he actually gets shirtless and flexes to the camera crew during the taping of their reality show.
• Nice Job Breaking It, Hero: He's one of the main reasons Chase has such a big inferiority complex. Plus, his klutziness and immaturity tend to break important things.
• Noodle Incident: In "Space Elevator," Adam thinks a government agent is coming to take him away, and implies he might have broken the law.
• Personality Blood Types: Type B. He seems to be more relaxed and even let his team think for themselves. His important lesson is "Don't be like Chase!"
• The Worf Effect: He once lost a fight against Spike.
• Took a Level in Jerkass: He became more annoying and mean-spirited in later seasons. Justified that it is only shown later that he truly loves pushing his sibling's buttons. If Lab Rats: Elite Force is any indication, Adam throwing Chase around was his way of showing his brotherly love.
• Real Men Wear Pink: He's a self-described "huge, muscular, beastly man" with Big Brother Bully tendencies, but he also listens to Taylor Swift, occasionally borrows Bree's lip gloss, loves animals, and wants to be a florist.
• Red Oni, Blue Oni: The Blue to Chase and Bree's Red, at times. Other times, he is the Red to their Blue.
• Relationship Sabotage: He tried to interfere with Chase and Sabrina's relationship in "Spike Fright" due to his jealousy over Sabrina being interested in Chase rather than him. He does it again to Bree and Jake Chambers in the next episode (but directed more towards Chase, who is disguised as Bree). That time around, he had no reason to do so.
• Sadist Teacher: In Lab Rats vs. Mighty Med, he doesn't think it's fun to do an exercise without using bionics, because no one will get hurt. This is a problem because Kaz and Oliver don't have bionics.
• Sensitive Guy and Manly Man: Manly Man to Leo's and sometimes Chase's Sensitive Guy. He tells Leo that his manhood is missing after he finds out that Leo has a fear of Sharks due to an incident involving a rubber shark.
• Spear Counterpart: To Bree, without the Alpha Bitch qualities.
• Super Not-Drowning Skills: Sink or Swim reveals he can breathe underwater. When he nonchalantly brings this up to his siblings, he seems genuinely surprised that they don't share this ability.
• Super-Strength: His main power, which is explored to ridiculous extents over the course of the series (see Did You Just Punch Out Cthulhu?).

Bree Davenport

Played by: Kelli Berglund

• Alpha Bitch: Moreso in Season 4 of Lab Rats, but zigzagged because her behavior borders more on childishness. Fittingly, her students are called the "Alpha Girls".
• Beauty, Brains, and Brawn: The Beauty to Adam's Brawn and Chase's Brains.
• Brought Down to Normal: As of Three Minus Bree, Bree destroys her bionic chip so she can live a normal life. When she realizes the consequences of not being part of the team, she wants her bionics back. Unfortunately, Douglas was the one who designed the Lab Rats' bionic chips, so there's no way for Donald to build a new chip.
  • Thankfully Leo convinces Douglas to help build her one in the next episode, restoring her to her former powers.
• Bratty Teenage Daughter: Becomes a plot point in Three Minus Bree. Her Evil Counterpart is much worse.
• Cute and Psycho: Only when she's Spikerella.
• Distaff Counterpart: To Adam (without the jock qualities). However, in a sheer twist of irony, Skylar filled that role more than Bree in an episode of Elite Force, when Bree starts receiving the treatment that Chase usually gets from Adam.
• Deadpan Snarker: Although not as much as Chase or Leo, she definitely has her moments.
• Drama Queen: She is prone to overreacting to a lot of minor things. Her Evil Counterpart in Parallel Universe, however, is much worse, to the point of being a Mall Rat.
• Flanderization: She becomes a bit meaner in Season 4.
• Foolish Sibling, Responsible Sibling: The foolish to Chase's responsible, and the responsible to Adam and Leo's foolish.
• Fragile Speedster: Played with. Like her brothers, she can survive punishment that would kill ordinary humans; however, she is also the least durable of the three, to the point that she easily got thrashed by a de-powered Skylar Storm in Elite Force.
• Genki Girl: Naturally.
• Girly Girl
• The Heart: She can also breaks up fights and arguments between her siblings when they get out of hand.
• I Just Want to Be Normal: Becomes a plot point in "Three Minus Bree," where she destroys her chip and quits the team. Her desire to be normal is so strong that she initially fails to realize how the team would be affected by her actions.
• Irony: Bree makes fun of Chase a lot for getting pushed around by Adam. In an episode of Elite Force, Skylar roughhouses her because Calderian sisters treat each other like brothers. After experiencing what Chase felt, being the sibling who got the short end of the physical strength stick, she lampshaded the treatment Adam gives to Chase.
• Jerk with a Heart of Gold: Her jerk side only really shows up in a few episodes, with "Three Minus Bree" being the most notable, but she's brutal when it does.
• Love Freak: Her inability to keep a boyfriend. Oliver did return her feelings, but Skylar killed the moment.
• Mad Scientist's Beautiful Daughter: The only daughter of Douglas Davenport.
• Manipulative Bastard: She uses her "girl cry" to trick Donald, but he doesn't fall for it.
• Middle Child Syndrome: In "Concert in a Can" and "Three Minus Bree". Technically, she's no longer the middle child with the addition of Daniel, but she was raised as it, as well as being the only girl in the family.
• Ms. Fanservice: She’s a pretty girl who wears a tight spandex suit (and later a Spy Catsuit) that shows off her curves.
• My God, What Have I Done?: Bree feels remorseful after she had purposely broken her chip in “Three Minus Bree”, which became the premise of the next episode.
• Personality Blood Types: Type O. She sometimes acts like an Alpha Bitch.
• Phoneaholic Teenager: She can't go one minute without her phone. In Bionic Dog, she takes Leo's smartphone and becomes romantically attracted to the phone's personal assistant.
• Red Oni, Blue Oni: Both. Red to Adam, Blue to Chase.
• Resentful Outnumbered Sibling: She's the only girl in the family, and often wishes she had a sister. This angst is part of what contributes to her current behavior. Thankfully, she has a sister who's about to be born, and she gets Skylar as a surrogate sister.
• Savvy Guy, Energetic Girl: The Energetic Girl to Chase's Savvy Guy.
• Sadist Teacher: Implied in The Vanishing. Either that or she takes a snoozefest.
• Slapstick: Due to the Double Standard, she has had far less Amusing Injuries than her brothers (i.e., in "Robot Fight Club", she's the only one of the Rats not on the receiving end of an Aikido throw). However she still occasionally has her fair share of injuries in episodes like "Quarantined" (slamming into a wall and falling down a flight of stairs) and "Prank You Very Much" (getting covered in spoiled milk and slipping on a wet floor). Then in Lab Rats: Elite Force, she gets thrown around (and given a wedgie) by Skylar.
• Smarter Than You Look: She's not the Brainy Brunette Chase is, but she's much smarter than Adam. She shows off her resourcefulness in "Bionic Showdown", and also in the Lab Rats: Elite Force episode, "Follow The Leader", especially when she suggested that Kaz and Oliver use their experience in a game they invented to free Chase and Skylar without collapsing the unstable building.
• The Smurfette Principle: Until Skylar Storm joined in Lab Rats: Elite Force, Bree was the only girl on the team.
• Super-Speed: He signature power.
• Took a Level in Jerkass: She isn't really nice as she was in the first season. To be fair, she got better when she had a Skylar being a sister figure to talk to.
• Team Mom: Starts becoming this when the Bionic Island comes around. She's quite annoyed with herself when she starts acting like Chase and Sebastian's mom.
• Tomboy and Girly Girl: Girly Girl to Skylar's Tomboy.
• Voice Changeling: Vocal Manipulation is one of Bree's hidden bionic abilities.

Leo Dooley

Played by: Tyrel Jackson Williams

• Action Survivor: A given when you're 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 made a beam collapse on Leo and destroyed his arm. Had the fire department not acted quickly, Leo would have died of blood loss. It's also lampshaded in Forbidden Hero, when the Lab Rats joke about Leo nearly dying on virtually every mission.
• 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). The shuttle was too heavy and accelerating too fast for Leo's arm to handle, so he tried to jump clear of it only for the shuttle to crush his leg.
• Audience Surrogate: In Season 1.
• Badbutt: 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 aim is 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 S-1 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, Leo's 'attack orbs' were very admirable. They were certainly flawed, but still impressive for a teenager to have built in a day or so.
• 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 he still had the guts to stand up to both Marcus and Krane.
• Ditzy Genius: His strategies are good, but he's a real klutz.
• Deadpan Snarker: He and Chase are the master snarkers of the show.
• Deuteragonist: Leo is often this to the main trio, but a good number of episodes center on his character, to the point where he's arguably a full protagonist as well.
• Foolish Sibling, Responsible Sibling: The foolish to Bree and Chase's responsible, and the responsible to Adam's foolish.
• Genre Savvy: In Curse of The Screaming Skull, Leo describes everything he recently saw in a horror movie marathon, and cites specific scenes in relation to what is happening regarding a metal skull that Perry took from an uncharted island.
• Hypocrite: In Bionic Birthday Fail, Leo ended up not getting invited to his own birthday celebration, yet Leo had no problem taking part in Chase's 16th birthday celebration that Chase himself wasn't invited to, even though he knows what that felt like. He also gets very upset when the Lab Rats make fun of his height, but does it fairly often to Chase.
• 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: He's rarely a jerk, although he gets mean when he gets jealous. This is especially apparent in Leo's Jam, when he embarrasses Chase in front of the entire school so that he can win over the girl he likes (who at the time likes Chase).
• 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".
• The Leader: In "On the Edge", he becomes one of a team composed of himself, a former enemy and a student with high appreciation for him.
• 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: He wants to be seen as more than that, but even the President thinks that all he brings to the team is comic relief. He grows out of this role after he learns to effectively use his bionic arm and becomes an important part of the team.
• Secret-Keeper: Though some of Davenport's projects are public knowledge.
• Screams Like a Little Girl: Stated explicitly in Cyborg Shark Attack: "Even girls said you screamed like a girl".
• Shorter Means Smarter: As short as Chase, but he is nowhere near as smart as him or a doctor.
• The Strategist: He often 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).
• 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, and in one mission, it was just him and Donald.
• The Team Wannabe: He becomes a part of the team as their mission specialist later on, but he's always desperately wanted to be bionic. He gets his wish, of course, in You Posted What?!, and becomes 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

• Anti-Hero: It's a bit hard to think of him as a hero after seeing how he treats his own family, like seeming to take pleasure from some of the Lab Rats' more physically exhausting or even painful training sessions. Even moreso after finding out that the reason Douglas was such a megalomaniac is because Donald used to make fun of him and beat him up.
• Abusive Parent: Became a plot point in "The Lab Rats Strike Back". He's generally a good man, he just seems have trouble balancing his responsibilities, and figuring out how to balance the Lab Rats' normal lives and their bionics.
• Alliterative Name
• Amazingly Embarrassing Parents: Both he and Tasha can be this, but he's the worst case of it because he clearly doesn't understand youth subculture. Whenever he tries to integrate himself in it, it's met with complete embarrassment.
• Badass Bookworm: In Quarantined, Davenport showed that he has some serious fighting skills - which were actually foreshadowed in Bionic Birthday Fail.
• Big Brother Bully: He was this towards Douglas in the whole of their childhood, and even invented a robot just to beat him up. In fact, that's the reason why Douglas hated him so much before his Heel–Face Turn.
• Bumbling Dad: Adoptive dad, technically.
• Cain and Abel: He's the Abel to Douglas' Cain. However, if 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. As the series progresses, it's pretty clear he's just as in the wrong as much as Douglas, especially when one takes into account his jerkass behavior, and he fact that he's been lying to the kids for years.
• Catchphrase: "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. Then we find out he has another nephew—Daniel, and he tries to be the cool uncle to him.
• Deadpan Snarker: To Tasha or Leo, usually.
• Demoted to Extra: In season 4, he has been appearing in fewer episodes and Douglas seems to be replacing him. His disappearance is justifiable, as he has Davenport Industries to run, and he needs Douglas to take care of the academy when he's really busy. This is really played straight in Elite Force, because not only does he have a company to run, he probably has to check up on Adam and Leo at the Bionic Academy, and he's got a baby daughter who's about to be born.
• Embarrassing Nickname: Douglas and Perry call him "Donnie".
• Expy: He has some similarities to Tony Stark.
• Good Is Not Nice
• Fatherly Scientist: Although he can be mean to them at times, he really cares about the Lab Rats.
• Hair-Trigger Temper: He gets angry rather easily.
• Happily Married: To Tasha.
• Hated by All: It seems no one really likes him, and in Bionic Rebellion, it's shown everyone's usually glad when he's not around.
• Hypocrite: All the time.
  • This is perhaps most prominent when he's telling Adam to lay off of Chase, considering he did the exact same thing to Douglas when they were kids.
  • In addition, Donald calls out Douglas for doing bad things and lying about them when he's no different himself, especially when it's revealed that Donald killed most of Leo's pets and lied to Leo about it for years.
• 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: Usually when he dabbles in his ego. He's not very respectful towards others, especially his employees and brother, and he has a self-righteous attitude.
  • Jerk with a Heart of Gold: He genuinely and wholly loves his family, and when he's able to keep his ego in check, he's a nice guy.
• Karma Houdini: Out of all the cast, he seems to learn his lesson the least, though he gets his comeuppance in episodes where his selfishness has serious consequences.
• Laser-Guided Karma: In Lab Rats vs. Mighty Med, Donald was such a colossal Jerkass to Chase by not letting him talk, nor caring a damn for his opinion, and it was about an invention Chase helped him build. Donald even went with a company that would pay the most, and without consulting Chase at all. Afterwards, The Incapacitator maims Donald, forcibly copies his retinal signature, and steals the invention. The Incapacitator may have been a ruthless villain, but the punishment Donald received from him was well deserved.
• Mad Scientist: Under Rule of Funny
• Manchild: The man's got a bedroom full of video games and action figures, and loves superheroes.
  • Psychopathic Manchild: Especially in "The Lab Rats Strike Back". Also, in Face Off, where he puts Leo and Douglas through sadistic tests for revenge and laughs.
• Mission Control
• Moral Myopia: Donald is very self-righteous to the point where he feels when he does something people can see as bad, it's justified, and he will dismiss it, but when Douglas does something bad, it's despicable.
• 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.
• 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...
• Nice Job Breaking It, Hero: Despite claiming that Douglas being a former villain ruined the family, The way Donald acted as a child is partially responsible for Douglas's past actions, and he absolutely refuses to admit that.
• 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, the whole mess could've been avoided if Donald had just done something sooner to help Chase. It could be argued that Donald was somewhat sympathetic towards Adam, having been that brother in the past, and that that's why he didn't say anything, and that Douglas was sympathetic towards Chase, hence why he helped him out by giving him the Laser Bo.
• Omnidisciplinary Scientist: Donald's a brilliant inventor, engineer, mechanic, theoretical physicist and pretty much every field of science.
• Parental Favoritism:
  • It's subtle, but he seems to hold this toward Adam, barely ever reprimanding him for his treatment of Chase. In "Brother Battle", when Douglas unlocks an ability for Chase that allows him to actually fight back against Adam's brute force, Donald is outraged.
  • He has shades this regarding Eddy, often disregarding how the computer treats everyone else, and openly calling him his best friend.
• Pride: Donald thinks too highly of himself, enough 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.
• Secret-Keeper: Donald is aware of the superhero world, but he kept it secret without any prompting from anyone. This was why he was the only person Kaz, Oliver and Skylar could come to when Mighty Med got destroyed.
• 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:
  Bree: Help me!
  Donald: Bree, do you mind? The adults are trying to have a conversation here.
• Suspiciously Similar Substitute: In Elite Force he he takes Horace Diaz's place as Kaz and Oliver's eccentric, wacky boss, though more annoying in Skylar's eyes.
• Took a Level in Jerkass: Lab Rats Strike Back makes him look like a complete douche, and gives him an even bigger ego than before.
• 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!

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. Though her appearances do decrease within each passing season.
• Happily Married: To Donald.
• 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 Woman: Towards Bree and Donald.
• Out of Focus: She is absent for almost all of Season 4 of the show due to living off the bionic island and being pregnant with a baby, making only four out of twenty-six appearances.
• 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.
• Sitcom Arch-Nemesis: Tasha and Eddy despise each other.
• Unfazed Everyman: She eventually grows into this.
• Women Are Wiser

Douglas Davenport

Played by: Jeremy Kent Jackson

• Anti-Hero: He certainly isn't the most moral fellow even now, but is on the good side regardless.
• Anti-Villain: In early season 3, due to Krane being Eviler than Thou.
• Affably Evil: Even at his most villainous, he was geniunely a carefree and jovial guy. He even suggested that the Lab Rats could work for him while still spending family nights together to show that he loves them in his own way.
• Abusive Parents: It's implied that his parents always ignored him over Donald. Played with in regards to the Lab Rats and Marcus; he does not remember their birthdays and wanted to use them to commit crimes, but he also has moments that show he does care for them, especially after his Heel–Face Turn.
• 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.
• Ax-Crazy: Before his Heel–Face Turn.
• Alliterative Name: Douglas Davenport.
• Ambiguously Bi: He dated Giselle in college, and there are tons of references to Douglas' and Krane's relationship being like that of a married couple, many of which come from Douglas himself.
  Douglas: Kids, this is my partner, Victor Krane.
  Adam: Wait, so now we have three dads?
• Ambiguously Evil: He gets more ambiguous with each appearance after "Bionic Showdown". When he was officially introduced, his agenda was hinted to involve 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 going to build some bombs, take over a tiny country, and steal money from old ladies. Douglas responds that he could do those things (albeit not in that order), but then says he just wants to get back at his brother and beat him at something. In his next few appearances, everything he does is done just to spite Donald, including blowing up the lab and stealing all of his money. Finally, in "Which Father Knows Best?", Douglas learns Bree smashed her chip, and that Donald can't fix it. At first he sees it as another thing he could rub in his brother's face, but Leo reminds him that there are more important things than winning against his brother, which leads into his Heel–Face Turn.
• Annoying Younger Sibling: Turned evil. He eventually lets go of this trait.
• Archnemesis Dad: To Adam, Bree, and Chase, although they didn't know it prior to "Bionic Showdown".
• Badass Bookworm: He's just as good a fighter (and a much more brutal one) as his brother and is more intelligent.
• Badass Boast:
  • "Do you want me to blow up the lab again? I'm good at it."
  • "Guess I just have to be the bigger man!"
• Badass Normal: Even without any powers, he went up against Krane, who was the most powerful character at the time, and came close to defeating him.
• Byronic Hero: He still doesn't have any morals, but he is on the good side.
• Beware the Silly Ones: He has a comedic side, but he used to be a cold blooded super villain and the most dangerous force the Rats faced until Krane came along. Even now, if you hurt his family he will make it bite you in the arse.
• 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 thick as thieves either, and that Krane kept many secrets from him.
• Big Bad Wannabe: He's reduced to this as Krane goes increasingly homicidal and mad with power, resulting in Douglas pulling a Heel–Face Turn.
• Big Damn Heroes: When he saved the Lab Rats from Krane.
• Belligerent Sexual Tension: Perry's dragging him into this.
• Butt-Monkey: He never really gets the respect he deserves. The President sees him as nothing more than "the help", nearly all jokes are aimed at him (especially in "You Posted What?!"), and he's also getting harassed by Perry.
• Cain and Abel: The 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 started out as a vengeance-driven megalomaniac obsessed with getting back at Donald. However, "Avalanche" shows that Donald had partially driven him into this, and he softens a little after teaming up with the Lab Rats to fight Krane. Leo convinces him that it isn't that important to get the upper hand over Donald, and Douglas slowly gains the family's trust.
• Chekhov's Gunman: Douglas is alluded to in "Exoskeleton vs. Grandma", but supposedly as part of a lie cooked up by Donald to come up with an explanation for Adam, Bree and Chase. Eventually, Douglas makes his appearance, and everything Donald said to Leo's grandma regarding him turned out to be accurate (except for him falling into a volcano).
• Chekhov's Skill: Remember how Douglas hacked into Davenport Industries and liquidated all their assets? He uses his hacking skills to create a virus to fry all of Giselle's servers.
• Chronic Backstabbing Disorder: Inverted. Two of Douglas's partners betray him: Victor Krane attempts to kill him when he was done with him, and Giselle uses a movie as a front to eliminate the Lab Rats.
• Chuck Cunningham Syndrome/What Happened to the Mouse?: 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. He is mentioned in "Bionic Rebellion" and returns in "Under Siege".
• Dating Catwoman: Perry tries this with him. He doesn't love her back, mostly because she's about in her late 50's. However, he doesn't want to hurt her feelings, so he plays along, but clearly doesn't enjoy it. One has to wonder why he doesn't just use a cybermask to hide himself from her.
• Deliberately Bad Example: Douglas' main purpose was to offset Donald's unpopular traits, showing that while Donald can be a jerk to everyone, he means a lot to the kids, whereas Douglas was ruthless to the point that he would use bionic humans as weapons. After his Heel–Face Turn, he's supposed to serve as this trope in a different manner by almost always breaking the rules and by making decisions that even Donald knows are legitimately reckless and probably illegal. This doesn't work because Donald's stubbornness and ego-driven jerkassery ends up looking more disreputable, causing Douglas's actions to be glossed over, which is ironic considering Douglas has a similar mentality to his brother.
• 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 acts up in "Under Siege" because it hadn't been calibrated to his nervous system yet.
• Enemy Mine: He becomes fed up with Krane after being betrayed by him and teams up with the Lab Rats in "Taken".
  • 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.

• Even Evil Has Standards:
  • When Krane tells him to use his Triton App update to destroy Adam, Bree, and Chase, Douglas refuses and explains that destroying the Lab Rats was never part of his plan, only to be told off by Krane. Despite later dialogue stating he tried to kill the Lab Rats 522 times, Douglas repeatedly emphasizes that he had no intentions of hurting Adam, Bree, and Chase even at his most evil.
  • It's later revealed in "Rise of The Secret Soldiers" that when he designed their chips, he installed a protocol that will allow them to fuse their bionics, but he didn't tell them because the results would be catastrophic and it was only to be used as a last resort. It's clear now that he never wanted to kill them in the first place.
  • Krane also wanted to put a doomsday virus in the Triton App that would activate in the event of his death. Douglas refused, but Krane added it anyways behind his back.
  • He made another kid, Daniel, who was a baby when Donald took the original three Lab Rats. As much as he wanted to use Adam, Bree and Chase as weapons, he couldn't raise Daniel while on the run, and chose to put him up for adoption to keep him away from all his chaos.
• Even Evil Has Loved Ones: He geniunely loved the Lab Rats, even in his villain days. He also loves his dog, Otis. Even after he discovers Krane turned Otis into his personal henchman, Douglas still couldn't hurt him.
• Evil Step-Uncle: To Leo, which the latter jokingly lampshades in "Face Off". After his Heel–Face Turn, it's an honorary title.
• Exact Words: Donald gets angry at him for upsetting the balance of power on the team, because he gave Chase a new ability. Douglas "restores balance" by giving Adam a new ability.
• Friendly Enemy: To Donald and the Lab Rats back in his villain days. He acted friendly towards them, even while fighting them. Leo, however, was the bane of his existence because he found out about his plan before everyone did. He only first approached Leo as a friend in "Taken".
• Faking the Dead: Apparently, he's really good at doing this. He was presumed dead prior to the start of the series.
• Faux Affably Evil: A straight example in his villain days: Always cheerful and friendly, but underneath it all was cold-blooded ruthlessness. Case in point, him suggesting he, Adam, Bree, and Chase plan family game nights while he's working to enslave them. He 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.
• Give Him a Normal Life: He put Daniel up for adoption for this reason.
• Good Is Not Soft: He is a nice guy, but don't expect him to go easy on a villain. Especially if they hurt his kids.

• Green-Eyed Monster: He is envious of his older brother, Donald, and it's implied to be at least partially responsible for him turning evil. He overcomes it after his Heel–Face Turn, though he still slips into this every now and then.

• Heel–Face Turn: After Krane decides he wants to kill Adam, Bree and Chase, Douglas begins to have second thoughts. As Krane gets more and more insane he turns on him to save his kids' lives, and truly redeems himself when he builds Bree a new chip and agrees to work with Donald to save her when it malfunctions. After some prompting Donald agrees to give him a second chance.
• Heroic Comedic Sociopath: He still admits that he has gone against the law, like it's no big deal. Usually, his response is to resort to the violent option if he's in a tight spot. In "You Posted What?", he suggests 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.
• Human Popsicle: Gets frozen solid by his brother's new freeze ray after Chase tricked him.
• Insufferable Genius: Like his brother and son.
• It's All About Me: After his Character Development, he gets rid of this mentality and becomes more selfless and caring.
• 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'. This did NOT bode well for him when Marcus came back. However, dialogue during Bionic Action Hero implies he does miss Marcus.
• Knight of Cerebus: He's much darker than most of the show's other villains, as well as most Disney villains at the time. 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, and before redeeming himself his long term goal appeared to be a mixture of brainwashing, slavery and Child Soldiers.
  • Even after his Heel–Face Turn, he still casually and (mostly) shamelessly admits to having committed countless crimes. However, that's closer to Comedic Sociopathy.
• Lack of Empathy: Douglas has trouble grasping the concept of empathy. Back when he was a villain this made him incredibly dangerous, and even after his Heel–Face Turn he still seems to have trouble with it outside his own family, describing potential horrific events or even deaths in a way that always relates to himself. However, he does have a sense of empathy and compassion despite that: it's clear he feels guilt for his past actions, and he turned on Krane when the other man went too far.
• 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 really terrible.
• The Lancer: He's now Donald's right hand man, and takes over the Bionic Academy when he's not there. Of course, if something goes wrong, he's the one who gets held responsible.
• Large Ham: Probably the biggest ham on the show. Especially when name rivaling with his brother, Donald, or in this case, "Donny!" In fact, the first thing he did when he came on screen was yell "I'M BAAAAACK!".
• Luke, I Am Your Father: He's the one who created Adam, Bree, and Chase. This means (almost) everything Donald said in Exoskeleton vs. Grandma was accurate all along.
• Manly Man and Sensitive Guy: The Manly Man to Leo or Donald's Sensitive Guy.
• Mad Scientist: An interesting example. Rather than being a stereotypical mad scientist. Douglas is instead presented as someone who is both close to realistically dangerously insane and 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.
  • In "Spider Island" he reveals that before he went into technology he tried to bring extinct species of animals back from the dead. He never cracked it, so him claiming to have reanimated his brother's dead gerbil might not have been a stretch.
• The Man Behind the Man: Douglas had a strong influence on every bionic-related incident that takes place in 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, psychopathic mastermind and genetically engineer his own bionic soldiers. Douglas also gave his ex-girlfriend Giselle his research on androids.
• Mr. Fixit: In the academy, he's the guy responsible for all their tech needs, supplies, etc.
• Mr. Vice Guy: Despite his Insufferable Genius traits and somewhat psychopathic 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.
• Papa Wolf: Say what you will about him, but the man loves his kids. He turns on Krane after the latter expresses wanting to destroy Adam, Bree and Chase, and offers his life to protect Daniel from Marcus (albeit as part of a trick, but the fact he didn't offer Donald up instead shows how serious he was being).
• 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 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.
• Revenge: Formerly motivated by getting revenge on Donald for doing nothing but overshadow and drag Douglas down his whole life, which screwed him up emotionally. He lets go of this after his Heel–Face Turn, not that Donald sees himself as responsible for any of it in the first place.
• Shadow Archetype: Formerly to his brother Donald. Donald is 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 in regards to his arrogance. However, it was Donald who screwed Douglas' life up in the past and is partially responsible for his behavior, but he doesn't take responsibility for it. After Douglas' Heel–Face Turn, Donald instead starts to become this to him. Douglas is portrayed as less responsible, but is more tolerant of his children's mistakes and can relate to them better than Donald, who just has way too much pride to notice how they feel. Douglas also isn't afraid to call Donald out when he treats them poorly.
• Take Me Instead: When he sees Marcus torturing Daniel, Douglas offers his life up instead, as he is the one Marcus hates the most. Subverted in that it's a trick to get Daniel to copy Marcus's abilities. Even so, the fact that Douglas offered himself as the bait and not Donald shows Douglas was willing to take responsibility and pay for what he did to Marcus.
• Tragic Villain: The reason he turned evil was that Donald (and, implicitly, their parents) mistreated him for so long that he became obsessed with getting the upper hand until Leo convinces him that family is more important than Revenge.
• 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.
• Truly Single Parent: Douglas never married, and he created Adam, Bree, Chase and Daniel via genetic engineering.
• Villain Respect: To Donald and the Lab Rats when he was a villain.
• We Can Rule Together: Tries this with Chase. It backfires horribly.
• Would Hurt a Child: Not his own, but Leo was fair game because he kept interfering with his plans.
• Uncertain Doom: In the season finale of Elite Force (which became its series finale after its cancellation) he is attacked and left for dead by Reese. His actor later confirmed that Douglas was alive, but it remains unknown whether he retained any lasting damage or not.

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.
• Arson, Murder, and Admiration: When Perry returns in the Elite Force episode Follow The Leader, she calls out Chase for locking Skylar in Mission Command so that she wouldn't upstage him, gives Chase a What the Hell, Hero? moment by telling him they're not so different after all, then gets impressed by telling him "You really could be my son!"
• Ascended Extra: Was more of a minor character in the first season, but began to appear more and more afterwards to the point of becoming a Fake Guest Star. She even has more appearances than Tasha.
• Badass Normal: Took down Spike all by herself and (maybe) 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. It ends when Lab Rats are outed to the rest of the world however to her dismay. On the other hand, she has more respect for Superheroes, because their powers are real compared to bionic people, the latter of whom she regards as robots.
• 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.
• Can't Live with Them, Can't Live Without Them: This is her sentiment towards the Davenports. Perry doesn't like them, but she enjoys having them around to hate. If anything bad actually happens to them, she would be devastated.
• 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, and that she's a chronic liar, it's not hard to understand why they wouldn't believe her.
• Child Hater: By Unauthorized Mission however, she decides that tormenting other kids isn't as enjoyable anymore, because Adam, Bree and Chase's absence made her life feel empty.
• Crying Wolf: Perry is a chronic liar, and says a lot of things that are unbelievable. It's later revealed she got fired from many jobs because she kept lying. You'd have to wonder how she kept her job as principal.
• Dating Catwoman: She tries this with Douglas - It doesn't work very well, because he's not in love with her. They almost got married in one episode. However, the only reason why he plays along is because he doesn't want to hurt her feelings.
• The Dreaded: Leo wants to stay away from her as much as possible, except when real villains threaten him. However fate just loves to throw the two together. In Lab Rats: Elite Force, vermin are stated to be terrified of her.
• 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.
• Fantastic Racism: She refers to bionic people as "robots" or "robotic people". Superheroes on the other hand, she adores.
• 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, she just likes to hate 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.
• Heel–Face Revolving Door: Depending on the plot, Perry is either an ally, antagonist, neutral or a combination of two of those.
• 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: She bullies her students, yells at her employees, and basically does everything she can to make people miserable. By later seasons, she's at least upfront and honest about being a jerk, and she is more or less understanding when people point this out to her.
• Jerkass Has a Point: As much of a jerk and chronic liar Perry is, she figured out Chase purposefully locked Skylar in Mission Command, and even revealed it all to Skylar while they were trapped behind a pile of rubble. Sure, she may favor Skylar over Chase, but Perry did seem legitimately angry with Chase when revealing the truth. It's one of the only things she does right in the franchise.
• 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.
• Jerk with a Heart of Jerk: Zig-zagged. 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.
  • A minor instance where after Leo gets promoted, she gives him his orange shirt, only to find she wore it to keep herself warm. When Leo asks why she didn't use a blanket, her response is "Because I wanted to stretch your shirt".
• 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. Happens again in Ultimate Tailgate Challenge, where she attempts to steal the Davenports' tickets just because they wouldn't invite her, and she burns them. Her punishment for this one? Game gets cancelled.
• 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's not entirely true).
• Nominal Hero: In Season 3 onward she seems to be shaping up to this. Perry is on the heroes' side because she only cares about self-interest, and just wants to have them around to torment.
• Obviously Evil: Moreso in Season 3 onward. While it's played straight in that she has a foreboding voice and comes off as selfish, callous no-good, Perry is the least malevolent antagonist involved.
• Percussive Maintenance: The only method Perry employs to fix broken technology, brute force.
• Pet the Dog:
  • She actually cared enough to send Leo and Douglas to the hospital after Krane and S-1'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.
  • In Space Colony, she constantly entertains the idea of the Lab Rats dying, but wished Adam good luck and claims he was always her favorite. When it seemed Adam died, Perry was for once, genuinely saddened at this, showing that she really meant what she said about Adam being her favorite. She also comforted Brew when they thought Adam was dead and hugged Chase upon learning Adam had survived.
• Rank Scales with Asskicking: Perry is a principal, but is the toughest authority figure in school, so it's not a good idea to mess with her. She was the only person in the school capable of taking down Chase when he was in Spike mode, and she was once a female Mexican wrestler.
• Running Gag: No matter where the Davenports end up, Perry ends up there too. At an Alien Gladiators convention, in the middle of the ocean, and in space. Even in Lab Rats: Elite Force she ends up making a presence.
• Sadist Teacher: Justified since she was a tough 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. She also keeps the secret that Kaz, Oliver and Skylar are superheroes.
• 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.
• 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).
• Teeth-Clenched Teamwork: With everyone she's allied with.
• Token Evil Teammate: She's mostly this in Season 3 onward. Perry may (mostly) be on the Davenports' side, but she's the most morally bankrupt, openly adhering to classical villain traits. In the end, the only side that matters to her is "the winning side".
• Took a Level in Badass: In Spike's Got Talent - she beat down Spike. Case closed.
• Took a Level in Kindness: Played with. Perry is still a jerk, but she has gained enough respect for the Lab Rats, because to her, they're not as weak as she believed. In the darkest of situations, she can show real kindness.
• Tyke Bomb: Her mother advised her to rule with an iron fist.
• What the Hell, Hero?: Perry, of all people, gives this to Chase for purposely locking Skylar in Mission Command, coldly telling him he's not so different from herself by doing so.

Daniel Davenport

Played by: Pearce Joza

• Cain and Abel: Abel to his android brother Marcus' Cain, which became evident in The Vanishing.
• Easily Forgiven: Daniel thought that Douglas didn't want him to come to the island, but forgives him after a talk with Leo.
• 11th-Hour Ranger: Introduced in And Then There Were Four as the fourth Davenport sibling, and joins the main cast in the finale against Marcus and Giselle.
• Long-Lost Relative: Daniel is the fourth Davenport sibling. He was a baby when Donald rescued the first three kids from Douglas, but Douglas had to put him up for adoption because he couldn't raise him while on the run; Daniel only learned who his father was after he turned thirteen.
• Power Copying: Daniel can replicate bionic abilities from humans and androids. However, the next set he duplicates will delete the previous set he copied.
• Replacement Goldfish: Marcus sees him as such, which cements his decision to betray Douglas.
• Story-Breaker Power: Daniel's Power Copying ability proved to be a story breaker because it means he will be as powerful as the next bionic person he comes in contact with. Since Marcus was the most powerful, Daniel could copy all his abilities, and turn them against him in minutes.
• Youngest Child Wins: Daniel was the only Davenport sibling with a bionic operating system compatible with an upgrade Donald created, even though Daniel was created before Krane's bionic soldiers (their bionic operating system is the latest compared to the Lab Rats). This gets solved when the original three Lab Rats' chips get destroyed, but end up replaced with a compatible operating system.

Eddy

Voiced by: Will Forte

• A.I. Is a Crapshoot: Surprisingly averted. Eddy is a pain in the butt but for the most part glitch-free (or is he, really?), while the AI in Davenport's car in Speed Trapped only went awry because of Marcus. On the other hand, he's not always as helpful as people expect.
• Deadpan Snarker: Contantly, especially towards Tasha.
• Even Evil Has Loved Ones: He does genuinely care for Donald and view him as a father. However, this seems to have ended in "Human Eddy", because he called Donald a has-been, and that was where Donald drew the line.
• Evil Versus Evil: More like Jerkass vs. Jerkass with Perry, but in the main characters' eyes, they're both despicable. In "Human Eddy", the two duke it out because there's only room for one of them.
• Fake Guest Star: The only reason Will Forte isn't in the opening credits is because he only provides his voice. He does get a chance to play him on screen when Donald makes a android body for him.
• Feel No Pain: After Perry restore his original personalty when he's in his new android body. He states he can't feel any pain so any damage they inflict on him won't work...least until Perry blasts him to pieces with a energy rifle.
• Hate Sink: Possibly the biggest in the series. He's a massive Jerkass who's hated by practically everyone that meets him and is almost always antagonistic towards the main cast. Unlike characters like Donald, Principal Perry, or even Douglas, Eddy constantly subverts any chance at improving himself and only gets worse as time goes on.
• Jerkass: Exaggerated. Eddy is constantly rude to everyone except Donald (and even then, that might just be because Donald created him and can effectively kill him with a push of a button]]. He's even worse when he's got an android body, because that allows him to be capable of physically harming someone. Apparently, he's so much a jerk that he makes Perry more tolerable.
• Jerk with a Heart of Jerk: He only claimed to help Leo save the Lab Rats just to annoy him afterwards.
• Grand Theft Me: Thanks to a flawed pill Leo created, Eddy ends up in Tasha's body, and does everything he can to ruin her life, not to mention numerous attempts to HURT her.
• Mission Control Is Off Its Meds
• Sitcom Arch-Nemesis: Eddy and Tasha despise each other.
• The Snark Knight
• Token Evil Teammate: Although all the family members have moments where they act like jerks, Eddy acts like a jerk almost every time he’s on screen.
• Took a Level in Kindness: Temporarily. when Donald makes a body for him in the 4th season. He re-writes Eddy's personality to be kinder and more helpful. Perry, however, found this annoying and re-wired him back to his old personality, not realizing that doing this to him when he's in a human body causes a whole heap of trouble.
• Troll: He loves making fun of people, especially Tasha.
• Used to Be a Sweet Kid: In "Scramble the Orbs", Chase used an early version of Eddy's programming to sell as a personal assistant. This version was polite and helpful, a far cry from the unhelpful Jerkass he eventually became.

Janelle

Played by: Madison Pettis

• Ambiguously Brown
• Butt-Monkey: Almost every episode she's in consists of her almost getting killed because of Leo.
• Deadpan Snarker
• Jerkass: Leo admits that sometimes she's mean.
• Official Couple: She and Leo are dating, as revealed in One of Us.
• Ship Tease: With Leo.

Caitlin

Played by: Michaela Carrozzo

• Competition Freak: When it comes to Domino competitions, Caitlin takes these to the point that she only cares about annihilating the other opponents.
• Drama Queen: She almost always complains about her boyfriend breakup troubles.
• Took a Level in Jerkass: Starting from Llama Drama, Caitlin has been quite a jerk towards Bree, such as working her like a dog in the Domino competition and not allowing her breaks, getting Bree to work with her at Tech Town so that she doesn't get the bad jobs anymore, etc.

Villains

Introduced in Lab Rats

Trent

Played by: Eddie Perino

• Arch-Enemy: To Leo
• Book Dumb: He isn't the brightest guy in school.
• Chuck Cunningham Syndrome: He effectively vanished after "Scramble The Orbs".
• The Dragon: To Principal Perry.
  • Dragon Ascendant: Briefly in Not So Smart Phone
• For the Evulz: The main reason he torments Leo, much like Principal Perry.
• Psychopathic Manchild: As of "Trent Gets Schooled", he is 18, legally an adult. Yet even after graduating and getting a job as the school's new gym teacher, he still acts like an immature bully.
• Kick the Dog: Steals Leo's clothes and reducing him to a towel.

Marcus Davenport

Played by: Mateus Ward

• All Your Powers Combined: He has super strength, super speed and super intelligence - the powers of Adam, Bree and Chase respectively.
• Always Someone Better: Douglas designed Marcus with all of the Rats' powers - at greater levels of effect.
• Antagonistic Offspring: Giselle brought him back to life, and Marcus wants revenge against Douglas for abandoning him and leaving him to die.
• Arch-Enemy: To Leo.
• Artificial Human: Marcus is a super-powered android.
• Back from the Dead: Giselle repaired him and got him working again. That doesn't last because Douglas blasts him with a weapon that melted him good.
• Chronic Backstabbing Disorder: If you've seen what he did to the Lab Rats, you'll most likely find out.
• Clashing Cousins: Since he's Douglas's robotic son, his rivalry with Leo could be seen as this, as he's Donald's stepson.
• Crocodile Tears: At the end of “Concert in a Can”.
• Cute and Psycho: Doe-eyed and adorable, but very dangerous.
• The Dog Bites Back: After being rebuilt, Marcus realized that Douglas never treated him like a son, so he proceeds to go after Douglas and make him and the rest of his family suffer.
• The Dragon: Originally this to Douglas. Later on, Giselle plans to make him into her Dragon in place of Troy.
• Eviler than Thou: He was far more evil than his father was as a villain. At least Douglas had redeeming qualities, but Marcus did not. But even with him, there is a sympathetic angle to him— deep down there's a part of him that wanted to be loved, because he never had any love in his life.
• Evil Counterpart: Marcus seems to be this for Adam, Bree and Chase. He doesn't however, have any of Daniel's powers.
• Evil Nephew: To Donald Davenport, and ambushed him with this fact.
• Et Tu, Brute?: Feels this way after Douglas abandoned him to his death in Bionic Showdown.
• Fascinating Eyebrow: Lampshaded by Leo on a few occasions. After his destruction, Douglas says he's turning the eyebrow into a bracelet.
• For the Evulz: Came off as Marcus' motivation, until it was revealed that he was probably just programmed that way. That may be the case, but in the finale, it came across strongly that Marcus never had any love from his father which is why he became so full of hate for his father and the rest of his family.
• Killed Off for Real: Marcus was killed by the falling rubble of Douglas's lair, but it seems Giselle wants to bring him back. She succeeds, but he's reduced down to his exoskeleton after the final confrontation and finally melted into metallic puddle by Douglas.
• Knight of Cerebus: Even more so than his father (Though only after Douglas mellows).
• The Heavy: In season 2, for Douglas Davenport.
• Inferiority Superiority Complex: Marcus knows that Douglas only views him as a weapon instead of a son, and uses his massive ego and condescension towards Leo to try and compensate for that.
• I Have No Son!: Inverted. In the series finale, Marcus renounces Douglas as his father, pointing out that Douglas doesn't see him as a son the same way he viewed Daniel.
• Jerkass: He betrayed the Lab Rats and threatens Leo whenever no one else is around.
• Manipulative Bastard: He was viewed as this to Leo, he happily used his seeming innocence to manipulate others.
• Never My Fault: Marcus blames Douglas for leaving him for dead. Sure, Douglas did run away, but it was Marcus' own stubbornness and arrogance that did him in, because he made the choice to stay behind and attempt to take out the Lab Rats.
• Redemption Rejection: In "The Vanishing", Douglas apologizes for the way he treated Marcus, and asks for him to let him try to be a real parent to him. Marcus refuses, preferring Revenge against everyone who wronged him instead. He does, however, seem to briefly consider it.
• Revenge: In the series finale, Marcus's main motivation was to get revenge on Douglas for leaving him for dead in Bionic Showdown.
• Ridiculously Human Robots: Marcus looks, moves, and speaks exactly like a human. Also, he can eat and drink for no real reason.
• Robotic Psychopath: Is really an android built by Douglas, likewise he fits every trait a psychopath needs.
• We Are as Mayflies: Bionic abilities in androids leads to them burning out very quickly. According to Douglas, Marcus had very little time left. Giselle fixed him so he could last longer.
• "Well Done, Son" Guy: To Douglas, who sees him as nothing more than a weapon, and Marcus has a cranky relationship with him because of this. Also seems to latch onto Giselle very quickly, calling her "Mom" until she says that they're not there yet.
• What Measure Is a Non-Human?: Douglas casually states that he’ll essentially die by the time he’s sixteen, clearly not caring at all despite presumably creating and raising him.
• A Wolf in Sheep's Clothing: Does this to get what he wants.

Victor Krane

Played by: Graham Shiels

• Abusive Parents: He mind-controls his own bionic children and forces them to be living weapons, before eventually programming all of them to self-destruct upon his death.
• Arch-Enemy:
  • To the Lab Rats as a whole, being their most powerful and dangerous adversary.
  • To Donald and Douglas, following the latter's Heel–Face Turn. Krane turns out to be such a massive threat that the two brothers finally team up in order to take him down. It's worth noting that when Krane reappears in season 4, Donald's reaction is not one of fear or panic; it's pure hate.
  Donald: (bitterly) KRANE.
• Ax-Crazy: His stoicism makes it less obvious, but the guy clearly loves destruction.
• Bad People Abuse Animals: He experimented on Douglas' dog, Otis, programming the pooch to attack its owner.
• Bald of Evil: He's the Big Bad of the series, and his head is as shiny as a chrome plate.
• Beard of Evil: In his first appearance, he's shaved it off by his second, but its back by "You Posted What".
• Big Bad: Krane is the main antagonist of the series. He's Douglas' benefactor and by far the most physically and financially powerful villain in the series. Even after his death, his creation of a bionic army leads directly to the events of season 4. And even then, he returns in the middle of season 4, where it's revealed that he survived and has been biding his time to enact even more destructive plan, solidifying him as the series' one true Big Bad.
• Card-Carrying Villain: He does nothing to hide any of his evil actions.
• The Comically Serious: Sometimes his deadly serious, "no nonsense mastermind" attitude can be viewed as somewhat humorous, especially in some of his interactions with Douglas.
• 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.
• Dead Man's Switch: Of a sort. He programs his bionic army to self-destruct in the event of his own death.
• Diabolical Mastermind: He absorbs the characteristics of a realistic evil mastermind. From his obsession of destruction, and taking over, down to his constantly serious personality.
• Drunk On Power: The more bionics Douglas installs in him, the more Krane's true, megalomaniacal self begins to show, with his plans growing in scope.
• Energy Absorption: He can absorb energy from anything.
• Evil Counterpart: To Donald Davenport. They're both wealthy egomaniacs who experiment with bionic technology, and neither are very good parents. However, Donald genuinely cares about his kids deep down and much of his treatment of them is out of a misguided desire to protect them. Likewise, Donald is (usually) ethical with his experiments, many of which are conducted to benefit humanity, and still treats the Lab Rats like actual people. Krane, on the other hand, doesn't give a damn about his kids (to the point of being willing to kill them if he dies), has no limits as to how far his experiments go as long as he gains more power, and all of his experiments are done solely for his own benefit.
• Evil Genius: An ingenious billionaire and scientist 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. Even back when Douglas was still an antagonist, Krane made him look like a saint compared to himself.
• Evil Wears Black: Almost always sports a black trenchcoat.
• Facial Horror: The right side of his face has some scars due to implanting some bionics into his body.
• Faux Affably Evil: Downplayed. He occasionally speaks in a polite and cordial manner, but will drop it pretty much immediately when in battle.
• 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.
• Kick the Dog: Too many examples to count, but here's some notable ones:
  • Attempting to burn Leo and Tasha alive in order to lure the Lab Rats out of hiding.
  • Having S-1 crush Leo's arm with a concrete beam, to the point it had to be completely rebuilt with bionics.
  • Programming his bionic army to self-destruct after his death.
  • An almost literal example when he programs Douglas' dog, Otis, to kill him.
• 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. Douglas, of all people, is shocked at how far Krane goes.
• Mad Scientist: Obviously. He studies Douglas' bionic tech in order to further en chance himself and create his own army.
• Mind over Matter: One of his powers, he tries to use it to strangle Douglas.
• Misanthrope Supreme: His plan is to replace all humans in the world with bionic humans.
• Mysterious Past: Nothing is known about Krane's past before working with Douglas, other than that he was incredibly rich.
• Narcissist:
  • Krane is absolutely in love with himself and the powers his bionics give him. He doesn't care about anyone but himself, to the point of betraying his closest ally and trying to kill the man's family.
  • Played for Horror at the end of season 3. Like many narcissists in real life, he views his "children" as mere extensions of himself. When he seemingly dies, it's revealed that he programmed all of his bionic soldiers to self-destruct after his death.
• No-Nonsense Nemesis: Comparing him to Douglas, he's always take his job seriously.
• Noodle Incident:
  • Douglas claims that he and Krane once went as Brad and Angelina for Halloween. Considering how dark and evil Krane is and that Douglas isn't exactly trustworthy, it's unclear if this actually happened.
  • Douglas also says that Krane used to electrocute him when they worked together, but never explains why.
• Not Quite Dead: Turns out Krane wasn't killed off—he survived being shot into the atmosphere, but just barely. A Mad Scientist named Dr. Gao found him and made him a Dark Lord on Life Support. However, that didn't last because the Lab Rats fired a missile at his ship in space, which killed him off for good.
• Offing the Offspring: Programs all of his kids to die if he does.
• Omnicidal Maniac: He and Dr. Gao built a large rocket that would wipe out all life on Earth so that they can populate it with their new bionic soldiers.
• Psychic Strangle: Apparently, this is his commonly-used tactic.
• Sadist: Practically every episode he appears in involves him trying to torture someone, usually to death.
• 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.
• Take Over the World: His ultimate goal is to rule a world filled with bionic soldiers.
• 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.
• Villainous Legacy: Krane may have been gone after Rise Of The Secret Soldiers, but his legacy took root and was still a threat to the heroes:
  • In one instance, Chase told Sebastian, who was one of Krane's lead soldiers, about him and it led Sebastian to continue the legacy his "father" started—by wanting to eliminate Donald Davenport, bend the bionic soldiers to his will with lies about Davenport, and rule over humanity.
  • It is discovered that sometime after Douglas betrayed him, Krane turned Otis, Douglas's long-lost dog, into his personal assassin by encoding a directive to eliminate his owner. Unlike the Triton App, this directive would not be affected by Krane's supposed death.
  • If Krane got killed, he upgraded the Triton App so that it would give off a doomsday virus that would take effect after months in the event he got killed.
• With Great Power Comes Great Insanity: Implanting himself with more bionics has driven him completely insane.

Giselle Vickers

• Big Bad: For Season 4. She wants to create an army of androids to eliminate all bionic superhumans. Her androids now lie in pieces, but now she wants to repair and rebuild Marcus and add his super intelligence to all her androids.
• Big "NO!": Screams this after she accidentally protrudes her own whip around herself, leading to her falling apart.
• 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.
• Family-Unfriendly Death: Although offscreen, it's heavily implied she was sliced from the spine up.
• Faux Affably Evil: Happy to turn on the charm, until she gets what she wants.
• For the Evulz: After she succeeds in locking up the Lab Rats and declares that the magnetic waves are powerful enough to melt their bionic chips claiming that once their bionics are gone that they will finally be rid of bionic humans. Chase rebuffs by asking that if her Androids are so much better than bionics than why does she need to destroy their chips. Giselle claims she doesn't, she just wants to watch them suffer a slow and painful death.
• 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.
• Hoist by His Own Petard: She ends up meeting her end when she accidentally retracts her whip around herself presumably slicing her in half.
• Killed Offscreen: We never actually see her death.
• 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.
• Lightning Lash In her second appearance she's seen using an electric whip as her primary weapon. It's sharp and powerful enough to smash cameras and cut through steel.
• Older Than They Look: Is about Douglas's age, but could pass for being younger.
• Pet the Dog: Though Pragmatic Villainy may be in effect, after the bionic students, along with the Lab Rats escape the room they were locked in due to Leo. They confront Giselle when Adam, Bree and Chase tell them to leave she doesn't even attempt to stop them claiming that Adam, Bree and Chase are the ones who keep getting in her way.
• Pragmatic Villainy: Giselle doesn't bother trying to stop the bionic soldiers from escaping after the Lab Rats tell them to escape, deciding they're not of any interest to her.
• 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.
• 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.

Doctor Gao

Played by: Ping Wu

• Big Bad: Of Space Colony. He's the one who rescued Krane, saved his life by giving a face plate to breath through and came up with the plan to use the injected colonists to rule the world, after first wiping out all life on it.
• Big Bad Duumvirate: He's Krane's new partner, and he assisted him in another attempt to create a bionic army, and they agreed to start anew by wiping out all life on Earth. However, he's the only one of the two to survive.
• Eviler than Thou: When asked by Bree why he's helping a madman like Krane, he responds by claiming that who's to say he's not madder than Krane. This might not be the case though, because when dealing with annoying people like Perry, he's a sniveling coward compared to Krane.
• Kill All Humans: Him and Krane planned to detonate a missile onto the Earth which would cause a nuclear winter that would take out all life. Then planned to repopulate it with their new bionic army made from the captured colonists.
• Mad Scientist: Creating missiles to take out humanity and injecting serums into innocent people to turn them into bionic slaves. It's pretty obvious why he qualifies.

Introduced in Elite Force

Roman and Riker

Played by: Booboo Stewart (Roman), Ryan Potter (Riker)

• Revenge: They want to get revenge on Kaz and Oliver, then eliminate every superhero in the world, because their father lost his powers (in order to save his life). They believe that a life without superpowers is a Fate Worse than Death.
• Sibling Team: The two are brothers.
• Suspiciously Similar Substitute: To Wallace and Clyde, the main villains of Season 1 in Mighty Med. Like Wallace and Clyde, they are supervillains who are brothers seeking to destroy superheroes in revenge. Unlike them though, they're played completely serious.
• Ungrateful Bastard: Mighty Med saved their father's life but at the necessary removal of his powers which they feel is an insult to him. So they turn to villainy in order to "avenge" him, and they have a bone to pick with Kaz and Oliver (since the two used to work there).
• Voluntary Shapeshifting: They are shapeshifters who can manipulate their molecular structure to take any form, a person, a thing, or even a deathly dust cloud.

Rodissiius

Played by: Eric Steinberg

• Abusive Parent: Rodissiius is shown to be quite horrible to his sons, and when they fail, he won't give them anymore chances.
• Big Bad: Of Season 1 in Elite Force. Rodissiius wants revenge on Kaz and Oliver for letting him live a life without superpowers instead of letting him die a superhero. He wants to destroy not only them, but every superhero in existence.
• Create Your Own Villain: Because Kaz and Oliver had to save his life by sacrificing his powers, that deed is the reason he became evil.
• Evil Counterpart: Incidentally, of Skylar Storm when she lost her powers. Like Skylar, he couldn't bear an existence without his superpowers, and he did want to seek revenge against those who took away his powers. However, his solution is to kill every superhero in existence.
• Fallen Hero: Was once a fighter for truth and justice, but became a vengeful supervillain after Kaz and Oliver sacrificed his powers to save his life.
• Shadow Archetype: Of Skylar, as both were superheroes went through the experience of losing their powers. This loss made them feel like they thought made them special, and living a shameful life amongst the superhero community caused even more grief. Like Skylar, he wanted revenge against those who took away his powers. However, a key difference is that Skylar remained a hero because she at least learned to adapt and had hope in her friends (which paid off in the end). Rodissiius on the on the other hand, let his grief consume him with revenge and envy against those who have what he lost. He is what Skylar would have become if she didn't cope with her loss and gave in to her despair when she lost her powers.
• Ungrateful Bastard: Probably the epitome. He wants to commit superhero genocide because Kaz and Oliver took away his superpowers, despite that if they didn't he would have surely died. If his sons' words were of any indication, he would've been more grateful if they let him die a superhero's death than live in a shameful position as a Normo.

Rodissius’ Children

• Always a Bigger Fish: Rodissius states that Roman and Ryker are the “nicer ones.” Implying that they are much dangerous than the latter two.
• Last Episode, New Character: They are introduced in the last episode of the Lab Rats/Mighty Med franchise.
• Nothing Is Scarier: We never see what they look like in human form. All we know is that they are not on the side of good.
• Sibling Team: They are siblings who work together in battle.

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.
• Laser-Guided Amnesia: When they were all liberated from the Triton App, they lost their memories of Krane. However, when Sebastian found out about what happened to their creator, most of them rebelled, not understanding why their creator had to be taken out. After much explanation, they accepted the truth about Krane.
• 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.
• Secret-Keeper: While the public believes that Donald is the Lab Rats' father, the bionic soldiers are only beings aware that Douglas is the Lab Rats' real father, because Donald told them in the process of explaining who Krane is to them.
• 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 6: 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.

Taylor/S- 1

Played by: Ashley Argota

• Amnesiac Dissonance: Once Taylor regained her free will, she started having flashbacks from her time with Victor Krane, and learned who she was back then. Unlike Sebastian, she doesn't revert back to evil, because her memories of Krane were traumatizing.
• 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.
• Cartesian Karma: Although not intentional on Leo's part, Taylor permanently loses her eyesight due to Leo using his bionic arm to push her to her limit. Even though she was controlled by the Triton App, she did still cause Leo to permanently lose his arm and get bionics, and it did have some sort of mental scar on Leo. In a way, Taylor kind of deserved it, but not in the present.
• 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.
• The Farmer and the Viper: Chase and the others were reluctant to help S-1, because was Krane's lead soldier and the deadliest, thus could turn on them like Sebastian did under that same logic. However, this trope ends up being averted because she knew how evil Krane was, and such trauma was what caused her to seek the Davenports' help. In the end, she didn't let her past nature an evil bionic soldier influence her and ended up staying good.
• 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.
• Irony: S-1 permanently injured Leo's arm in You Posted What?!?, forcing Douglas to give Leo a bionic right arm. Leo's bionic arm ended up causing her permanent damage to her eyesight.
• 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. Her last appearance shows her to be blinded by an injury in training and, despite it seeming like she will continue to improve her skills, she is never seen again.

Sebastian/S- 3

Played by: Cole Ewing

• Amnesiac Dissonance: Sebastian wanted to know about his last battle with Chase, which led Chase to tell Sebastian about Krane and his evil plan. However, he started putting pieces together and figured out Krane's agenda, and he sought to continue what Krane's original agenda of taking over the world.
• 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.
• Anti-Villain: If he would have listened to reason, he would understand that his father was not a good guy under any circumstances. Too bad he became filled with vengence.
• 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.
• Fallen Hero: Starts out as a genuine hero and top bionic student, but after finding out about Krane's death, it all ends.
• The Farmer and the Viper: Sebastian was one of Krane's lead soldiers who was a tool for evil. After being released from the Triton App he was fairly stable, and the Davenports tried to train him to be a hero, even though he was a jerk. When Chase revealed his origins, Sebastian went back to being evil and turned on Davenport, despite all the good he tried to do for him, and despite telling him how evil Krane was.
• Jerkass to One: Before his Face–Heel Turn, he butted heads with Chase a lot because of Chase's authority, but he's a Nice Guy to everybody else.
• 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.
• Tragic Villain: He was definitely a good guy at first, and he would have stayed as one, if only he knew that his father was an irredeemable madman, who tried to enslave the world (and blow them up if he died). Though everyone tried to reason with him, it didn't work.
• 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.

Spin

Played by: Max Charles

• Chuck Cunningham Syndrome: He hasn't appeared since Mission Mania.
• 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.
• Tornado Move: His main bionic ability is that he can spin like a tornado.

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. After Spin stops appearing on the show, Adam fills in as the other guy.
