Angst? What Angst?: Most of the kids seem to get over the deaths around them fairly quickly, but given their situation it's understandable they've tried to numb themselves to such losses and it's obvious all of them are not in a good place mentally.
Diagnosed by the Audience: Gia struggled with depression and possibly had suicidal tendencies maybe, but who knows what was really up with her since this is only explored through the discussions of her fellow Campus members after her death where she was very obviously not looking to kill herself.
Nightmare Fuel: The whole series arguably. However, the deaths are strong examples. Alex being burned to a crisp and Trilby being hacked into and physically merged with a mechanical monstrosity being among the most prominent.
Too Bleak, Stopped Caring: Kids start dying on page one, and it's never clear why they're being killed or what Quinlan's motive or who his backers are making the series dark and depressing with no real payoff.
Adorkable: Leo can be sly and sassy sometimes but still manages to be undeniably lovable in a quirky, awkward and nerdy way.
Anti-Climax Boss: When Marcus regenerates at the end of The Vanishing and seems set to have one last battle between him and Leo, he gets instantly vaporized by Douglas' laser cannon, right before Leo can even make a move.
Anvilicious: Considering the episode aired on Earth Day, the subplot of Simulation Manipulation hit the viewer with an Earth Day message every three minutes by playing up Bree's levels of messiness and the trash wars Bree and Leo engaged for a portion of the episode.
Perry has become more of this in Season 3 onward. A good number of fans like her more since she acts more human in later seasons, but she's still hated because of her general Jerkass behavior. Because of this more positive reception, Perry makes it into Lab Rats: Elite Force, but the result is still the same.
Donald. He's narcissistic and often times a Designated Hero, and you'll find people either loving or hating him for it.
Adam, Bree, and Chase can be liked for their funny moments and care for being heroes, or hated for their own flaws; Adam for being a Big Brother Bully to Chase, Bree for her occasional Alpha Bitch moments, and Chase for being an Insufferable Genius.
Cargo Ship: A lot of fans kept shipping Chase and the floor, because of his tendency to end up on it many times.
Complete Monster: Victor Krane is a ruthless, power-hungry billionaire who gains bionic powers through Douglas Davenport's technology. Brainwashing Douglas's nephews and niece, Krane attempts to have Adam and Bree kill Chase for resisting. Building himself an army of superpowered teenagers and children, Krane has them brainwashed and stripped of any identity to become more effective soldiers, later attempting to expand his own brainwashing abilities to try to mind control all of Earth into subservience to himself. Viewing his underlings as nothing more than extensions of himself, Krane also installed a virus into them such that they would die when he did. After his seeming death, Krane returns to infiltrate Donald Davenport's space colony, kidnapping and brainwashing the colonists to build himself a new army and launches a missile that will wipe out all life on Earth, so that he can rule over the remnants.
Designated Hero: A good bit of the protagonist cast can tend to be this, as they ocassionally cause the problem of the episode every now and then as a result of their antics, as well as their pretty over the top antagonizing of one another in several episodes. For instance...
Chase, despite usually being the Only Sane Man of the group, tends to lapse into this. He sometimes acts like an Insufferable Genius to nearly anyone, but considering how Adam treats him, that's not completely unjustified either. Not to mention he used his students to cheat his way to victory, and was almost going to get away with it if it wasn't for Adam.
Bree can sometimes shift into this too, Depending on the Writer. It's implied in The Vanishing that she lowers her students' self-esteem. And in some episodes, she's pretty much evolved into a female Adam. Considering she's the only girl in the house, it's not hard to understand why.
Adam is a bit of one too, particularly with how often he antagonizes Chase to a degree so over the top it loops to pretty brutal, but considering how Chase treats him, that's not completely unjustified either.
Even Donald lapses into this, mostly as a result of his Parental Neglect for the team stemming from either him focusing too much on them as a team of heroes rather than his children, or letting his egocentric business take priority over them. One major example, in the crossover episode with Mighty Med, he was unjustifiably a jerk to Chase to hog the spotlight to himself, didn't care about his opinion, and was completely selfish and only cared about himself. The Incapacitator comes in and gives him his comeuppance.
Ensemble Dark Horse: Alternate!Perry from "Parallel Universe" due to being more likable than her standard counterpart. Fans even wanted her to become a main character in Bionic Island, giving delicious cookies to the students and doing a better job being a security guard.
Douglas, who is known by many as the funniest character on the show, despite being a main supporting character, and he is one of the few to make it to Lab Rats: Elite Force.
Krane, Marcus and Giselle are this too. Fans even wanted the former two to come back in Bionic Island(a wish that was granted).
Evil Is Cool: Victor Krane is well-liked due to being a ruthless, powerful, and effective Knight of Cerebus who owns every scene he's in.
After Marcus gets killed in Bionic Showdown, fans believe he is still out there and Not Quite Dead. He was dead, but since he's an android, he can be repaired, and Giselle found his remains.
In Rise of The Secret Soldiers, S-1 and Victor Krane are presumed deceased after they were blasted in the sky. However, many fans believe they somehow survived. Turns out S-1 survived, and she isn't evil anymore.
Likewise, Krane really was just hiding. He suffered fatal injuries, but a Mad Scientist found him and gave him life support. However, Krane's tenure doesn't last past the special, but there are still people who believe otherwise.
The episode Back From the Future in season 1 involves Future Leo warning his present self and Donald about a mission that Adam, Bree, and Chase don't survive. At the end, Adam remarks that they don't have a lot of time to make fun of Leo's height. A few seasons later, Leo is now taller than Bree and Chase. That being said, Adam now makes fun of Chase's height.
Bree says in Space Colony "I don't know if aliens exist, but if they do, they are going to hate you." By the time of Lab Rats: Elite Force Bree does find out Skylar Storm (whom she met in Lab Rats vs. Mighty Med) is an alien, and Skylar expresses how uncomfortable she is with Davenport.
Throughout the show, there are occasional comments about Donald getting something waxed, including one from Douglas in "Avalanche!" about it being a genetic thing. If Spencer Boldman's current appearance is any indication, it seems Adam inherited it too.
Hollywood Homely: Chase is often made fun of (in particular by Adam) for his inability to get girls, and is made out to be...not irresistible. While Billy Unger isn't necessarily as shredded as Spencer Boldman, he's still pretty built and attractive in his own right.
Marcus crossed it when he programs Donald's car to drive Leo into the ocean.
Krane crosses it when he tries to outright murder Chase, as opposed to enslaving him as Douglas wanted, simply cause he was resisting their control. He later uses government satellites to signal the Triton App to the whole planet. It's later revealed in "One of Us", that Krane programmed the Triton App so that if anything happened to him all bionic people controlled by it would die as well. Keep in mind these are dozens of children and teenagers were talking about. To top it all off, he experimented and tortured S-1, which left her really traumatized.
Sebastian crosses it by trapping Donald and Perry on the Hydraloop, and blowing up the end of the tunnel so that they will die after running out of oxygen.
Giselle crosses this when she tried to rip Chase open to retrieve his chip, and planned to wipe out bionic humans after updating her Androids just to eliminate competition.
Troy crosses this by planning to not just wipe out bionic humans, but all humans. He later took Bree hostage, and attempted to have the Lab Rats surrender under threat of her dying as well.
One-Scene Wonder: Leo's magic tricks. He is so good that he can make a group of rings disappear just by blowing at them.
Periphery Demographic: This show is intended to attract pre-teen boys, but Adam and Chase's good looks have attracted a sizeable amount of female viewers. The show's actual male audience have some people showing up just for Bree.
Ships That Pass in the Night: The Adam/Owen ship has been slowly rising in popularity even though they have exactly one episode of amicable interaction, that being "Spike's Got Talent".
Spiritual Successor: A trio of siblings who were created in a lab and have to balance living normal lives with managing their superhuman powers and using them to fight evil. Sounds familiar? Not just that, but both shows have their sibling trios discover that one of their enemies was responsible for their conception. In The Powerpuff Girls, Mojo Jojo was the one who caused Professor Untonium to break the Chemical X container and spill it into his concoction, creating the Powerpuff Girls as we know them; here, Donald's long-lost brother Douglas turns out to be the Lab Rats' real father, having created them to be supersoldiers for the government.
Strawman Has a Point: In Lab Rats vs. Mighty Med Oliver (pretending to be a student) asks if they can do training without bionics, but Adam thinks it's less interesting. However, Oliver's statement had prudence later on in the series finale, because Giselle destroyed all the bionic soldiers' chips and they didn't know how to fight without their bionics.
They Wasted a Perfectly Good Character: Leo's student teammates Taylor (AKA S-1) and Logan from the "On The Edge" two-parter. We don't even see Leo's bonding with Taylor after she arrives at the academy, and Logan only shows up in said two-parter as a borderline Satellite Character to the two. The two don't even show up in the series finale!
Spin disappears after the first few episodes of the 4th season despite being a Foil to Leo and never gets his chance to go on a mission.
They Wasted a Perfectly Good Plot: Bree destroying her bionic chip and turning normal in Three Minus Bree is resolved in the next episode.
The threat that the government owning Adam, Bree, and Chase would lead them to be used as soldiers is not only revealed to be an unfounded worry (since the bionic trio merely tour the world and give interviews), but is also put to rest when control over the trio reverts back to Mr. Davenport.
is any indication, it seems Adam inherited it too.
