History Series / LabRats

** The final season recieves a major update to the OpeningNarration and Leo's quote following such, to reflect the ReTool to Bionic Island.

** Adam taking home an animal/living being that's randomly unattended; A horse in Season 1, a llama in Season 2, [[TheLastOfTheseIsNotLikeTheOthers 30 bionic solders]] in Season 3, Otis (who happened to be Douglas's dog) in Season 4.

* GoodCounterpart: Principal Perry has one in a parallel universe.

* KarmaHoudineWarranty: In ''Scramble The Orbs'', the school board has been observing Trent's actions, and warn him not to abuse other students anymore since there's a huge difference between a student bullying another student and a faculty member harassing a student.

* StockScream: In ''Bionic Birthday Fail'', Adam trows a ninja away, who shouts a Wilhelm Scream.

* DiagonalCut: spoiler:Implied to happen to Giselle in the series finale, courtesy of her own laser whip; we see it wrap around her with no ill effects, but once it cuts away, we hear her pieces falling to the floor.

* [[AmazinglyEmbarrassingParents Amazingly Embarrassing Parent]]: Tasha plays this in "Trucked Out". Even Donald is not well-versed in teenage culture.

* CandidCameraPrank: Donald's slide show showcasing his security cameras catching the kids misbehavior, in ''Drone Alone''. [[InvertedTrope Inverted]] when Eddy refuses to reveal what Marcus did in ''Concert In A Can'', and [[WhatThehellHero says nothing about his activities]] in ''Mission:Space'', ''Who Is Marcus?'' and ''Speed Trapped''.

* MirrorUniverse: In the episode ''Parallel Universe''. Things are very much opposite; to begin with, Leo in that world has the bionics of the Lab Rats along with abilities he's never seen before, and Adam, Bree and Chase are neither bionic nor related to Donald, but also EvilCounterparts in the sense that they are antagonistic to Leo after finding out he is bionic. Personality wise, Donald is an insecure inventor-in-training, his mom is a {{Jerkass}} tech mogul who abuses Donald, Adam, Bree and Chase have opposite personalities (Adam is philosophical, Bree is an even bigger brat than her main counterpart, and Chase is a {{Jerk Jock}} instead of a snarky nerd). In addition, Principal Perry is good, kind and altruistic, even helping Leo escape the government agents and the Lab Rats' alternate counterparts.

** In the series finale, Adam dancing to distract Giselle is the exact same trick Star-Lord used on Ronan the Accuser in ''Film/GuardiansOfTheGalaxy'', and it worked.
** As pointed out by [[https://www.youtube.com/watch?v=roV6e1Q8J_A this video]] one of the characters was seeing [[VideoGame/{{Persona 4}} a Japanese exchange student named Yu]].

* AmbiguouslyBrown: Janelle.

''Lab Rats'' is a ScienceFiction KidCom that airs on Creator/DisneyXD.

Ever since ''Lab Rats'' premiered, it has been Disney XD's top-rated live-action series. For its fourth season, the series underwent a {{Retool}} with the main cast now mentoring other bionic teens at Davenport Bionic Academy, an artificial island (also earning it the [[NewSeasonNewName new subtitle]] ''Bionic Island'').

The series ran for four seasons from 2012 to 2016 with its final episode, the two-parter ''The Vanishing'', having aired on February 3, 2016. In addition to several RedSkiesCrossover and CrossThrough links with other Creator/DisneyXD series, it was announced in September 2015 that both ''Lab Rats'' and ''Series/MightyMed'' would be replaced by a permanent crossover series called ''Series/LabRatsEliteForce'' which ran for one season.

* TheUnmasqueradedWorld: [[spoiler: Starting mid season three the Lab Rats are exposed to the world by Victor Krane.]]

* TheUnmasqueradedWorld: [[spoiled: Starting mid season three the Lab Rats are exposed to the world by Victor Krane.]]

*** Taken UpToEleven when Douglas' benefactor Krane (who has also been given bionics) shows up, and demonstrates that he has zero consideration for the well-being or lives of anyone who gets in the way of his plans.

** UpToEleven in "Memory Wipe".

* SortingAlgorithmOfEvil: First we have Principal Perry, a ruthless, tyrant principal who [[ForTheEvulz enjoys making students grovel at her feet]]. Later, there's Marcus, an AxCrazy bionic android who has it out for Leo the most, and blackmails him into keeping quiet about his true nature. Then, there's Douglas Davenport, Donald's evil brother who wanted to use his creations as SuperSoldiers. Finally, there is Victor Krane, who is bionic and wants to use his powers to [[UpToEleven kill the main characters]].

--> '''Leo:''' I'm sorry. I just got a little carried away... with you carrying me away. (Beat) Oh come on, it's funny!

* SpiritualSuccessor: The cast makes it sound like this for [[Series/WizardsOfWaverlyPlace Wizards of Waverly Place.]] Not only do they share the same director and some crew, but both are about families with special abilities that need to keep a secret while attempting to live normal lives and going on adventures. Technically speaking, they both also rely heavily on special effects as well as occasional fight scenes.
** 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. [[WesternAnimation/ThePowerpuffGirls Sounds familiar?]]
*** Not just that, but both shows have their sibling trios discover that [[spoiler: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.]]

* AbsenteeActor: While Leo and the titular trio have had perfect attendance so far, Donald is absent from many episodes, such as ''Death Spiral Smackdown'', ''Air Leo'' and ''Spike's Got Talent''. However, he is sometimes mentioned in these episodes because of his inventions.

** Actually, expect this to be in play rather often thanks to the episodes usually having an A and B plot to work with. In "Which Father Knows Best" for example, while the A plot involves Donald and Douglas feuding while also struggling to fix Bree's bionic chip, the B plot involves a comedic series of events from Adam and Chase trying to figure out how to get around due to Bree no longer having her superspeed.
