"Alpha, Rita's escaped! Recruit a team of teenagers with attitude!"So the Big Bad has been unleashed, or the rebellion needs more help over-throwing the evil empire. Who do you get to help? A crack team of trained mercenaries? How about some expert martial artists? Maybe the existing peace-keeping forces such as the police or military? No? Then how about those kids standing over there? Yeah? Okay, cool, go for it. This trope happens when, instead of getting qualified help from highly trained professionals, or at the very least, adults who are more likely to understand the risks associated with a possible life-or-death scenario, we're treated to a team of young people with little to no experience with whatever they're about to face and thrust into it head first. Often, the teens are given weapons or powers to defeat this threat, but are given little to no training with these things yet still come out on top. The story will likely give one reason or another for why they couldn't go with the above but out-of-universe demographic appeal is the chief reason. This trope usually occurs in media aimed at kids and pre-teens, as that's the sort of audience who looks up to high schoolers as the pinnacle of human achievement, or at the very least are more relatable than some "crusty old" 30-somethings. Ironically, many such shows, if live-action, will invoke Dawson Casting and those "teenagers" won't really be teenagers anyway. Many stories sometimes have a token teenager, or may even have a whole sub-cast of children, but this trope is for when most or all of the main cast are teens (or younger). So Wesley Crusher from Star Trek: The Next Generation wouldn't count here. Similar to Ragtag Bunch of Misfits and Child Soldiers. Tangentially related Adults Are Useless.

open/close all folders
Anime and Manga
- Purposefully invoked in 7 Seeds. The Teams are made up of people who were specifically chosen to be healthy, have no history of hereditary diseases, malformations or any kind of disadvantage like poor eyesight or similar, so they can repopulate the earth, meaning that majority of them are in their late teen-years with a few 20 year olds here and there, not counting the guides. Done on purpose by raising them that way with Team Summer A.
- Sailor Moon: It seems like all the girls are picked at random, but as it turns out, they're all reincarnations of their old selves from the Silver Millenium.
- Tokyo Mew Mew seemed to pick 5 random girls who were just in the wrong place and wrong time. They just happened to have DNA that was compatible with the chosen animals.
- Mazinger Z: Kouji and Sayaka (and Boss) are sixteen, and they pilot giant robots to save mankind.
- Combattler V: All Combattler team members who pilot the titular Combining Mecha but Kosuke are teenagers.
- Getter Robo, at least in the original continuity where the intented pilots are all killed.
- Subverted in other continuities: The original Getter Robo pilots heroes are chosen because they are insane teenagers with attitudes.
- Neon Genesis Evangelion: Shinji and Rei are fourteen and Asuka is thirteen. They are mecha pilots.
- Science Ninja Team Gatchaman: With the exception of Jinpei, all Gatchaman team's members are teenagers. In a scene of the 2002 comic-book series, Ken says that everybody expect that they act like immature teenagers but he won't give them the satisfaction of proving them right.
- Bokurano: The main characters were very young children.
- Prétear. Granted, it's justified in the case of the Leafe Knights—they're literally born into the role and not exactly human, so they've been training for this their entire lives. (Plus, the four older knights only look as if they're in their late teens or early twenties, but they're actually at least twice that.) However, this trope is played completely straight in the case of the eponymous Magical Girl—Himeno is about 15, has no formal training besides an interest in martial arts (that she doesn't even seem to use in battle) and is completely mentally unprepared for her role as world savior. This is dealt with in-series during her constant battles with self doubt, as well as Takako/Fenrir's backstory—she was also a teen unprepared for battle, and focused obsessively on Hayate to give her the confidence to continue, which was why his rejection of her was so earth-shattering.
- Ronin Warriors: It was so bad that in the first episode they almost lost due to what was basically a pissing contest, and they spent the rest of the season paying for it.
- The Eldoran sries (Nekketsu Saikyo Gosaurer, Zettai Muteki Raijin-Oh) does something like this, except that "teenagers" is replaced with "A class of elementary school kids".
- Robot Taekwon V combines this with a Ragtag Bunch of Misfits, and the Big Bad is defeated by a teenage boy, his Action Girlfriend and his friends.
- Mao-chan one-ups this. Due to publicity issues, Japanese military had to resort to getting a trio of ridiculously cute little girls to stop alien invasion. And make a television show about it. Somehow it worked.
- In Dragon Ball, Dr. Gero tries doing this to defeat Son Goku, turning a runaway brother and sister into super-powered cyborgs. It doesn't end well.
- Puella Magi Madoka Magica: Kyubey only recruits young and inexperienced teenage girls to fight the Witches. Most of the main characters are completely normal schoolgirls. Kyubey's true goal is to convert their despair into energy, suggesting he picks teenagers because they're more emotional and/or easier to manipulate. He mainly targets teens with serious emotional trauma—Mami, for example, was recruited right after a car accident killed her parents and left her mortally wounded—because they have more energy-generating potential.
- The Pretty Cure franchise does this virtually all the time. Yes! Pretty Cure 5 had Nozomi personally choose who was gonna be a Pretty Cure (with the general formula being that they would blow it off, new monster show up, realize she couldn't abandon the others, come back and become a Pretty Cure). HeartCatch Pretty Cure! is probably the only one who doesn't follow this formula.
- Sort of done all throughout Digimon, though they're more of the tween-age in most of the shows - all apart from Digimon Savers, which stars a Hot-Blooded street punk that's recruited by a secretive government organisation when he forms a partnership with and Agumon.
- Borderline in The Lucifer and Biscuit Hammer; played straight for all the teenage characters - Yuuhi, Amamiya, Mikazuki, Tarou, and Hanako, but the age of all the Beast Knights ranges from primary schoolers to the 40-year-old detective Nagumo.
- In the first season of Yu-Gi-Oh!, the kids were fighting for personal reasons. However, as the series went on, they got increasingly roped into "save the world" situations, despite being high school students. Justified, by the fact that Yugi, as the Chosen One and the world's best duelist in a world where card games can destroy worlds and damn souls, was often the only one qualified to deal with the situations and the rest of the gang got involved simply because of the Power of Friendship.
- Played with in one episode of Yu-Gi-Oh! ARC-V. Although the LDS trio is sent out as bait to catch a serial soul-stealer, it's because they've met him before and he's more likely to target them. Also, they spend the entire mission being watched by their superiors and the dialogue implies that the moment they found the criminal, an elite team of agents was sent to their location to capture him. The teenagers still get to duel the criminal, but only because they chose to engage him instead of stalling for time until help arrived.
- After the bloodbath that is Mobile Suit Zeta Gundam, Bright Noa and the Argama had no choice other than to recruit Judau and his barely teenage friends to defeat the entire Neo Zeon. Lucky for the Argama these kids proved to be powerful Newtypes.
- Played with in Digimon Tamers, as for a good chunk of the series the adults refuse to work with the kids and even at the end make several good arguments why using them as frontline soldiers is unethical.
- Mighty Morphin' Power Rangers (Boom! Studios) finally answers this. Zordon did try to recruit capable people with training but it didn't work out because they couldn't tolerate one another and got killed on the first mission despite their abilities. In the end, he decided it was easier to hire a group of friends willing to do the job and train them than to hire professionals and force them to bond despite unreasonable differences and prejudices.
- X-Men: Though in this case, the X-Men did receive combat training prior to their first mission. It bears mentioning that the team's youngest member was only 13. Justified in that mutant powers manifest at puberty, and Xavier started a school for "gifted youngsters" to train them in their potentially uncontrollable and deadly mutations.
- In Ultimate X-Men, the team barely has time to be assembled and forced into tight leather pants before being sent to rescue a young mutant from 50-foot killer robots.
- Played straight, and extreme, in the Marvel comic Power Pack, which chronicles four pre-teen siblings who received their superpowers and world-saving mission from a dying alien. This was actually a subversion of the more typical adult, Serious Business superheroes of the time, and much of the humor since has come from contrasting them with heroes like Wolverine.◊ Similar to the Animorphs situation, the alien was dying, the kids were there, and the alien didn't exactly have the option of going and getting the Marines.
- Supergirl—an incredibly powerful sixteen-year-old who was a ball of angst and anger issues before her Character Development—agrees to work for the DEO—a Government agency in charge of neutralizing alien threats—in Supergirl (Rebirth). Director Chase notes that her newest agent used to be out of control.
- The Zodiac Starforce, who were all fourteen when they started out as magical girl warriors two years prior to the series' beginning. The first issue implies this will be deconstructed, as Emma points out that they experienced some fairly traumatic things and even witnessed the deaths of people close to them when they were fighting Cimmeria.
- Champions (2016) deals with this idea as Kamala Khan feels that today's heroes don't work as heroes anymore and there needs to be a new set of heroes to show them how it's done. It probably helps that she was an Avenger once along with two others.
- In W.I.T.C.H. both the current and the previous team of Guardians of Kandrakar were chosen as teenagers (Cornelia actually wonders why them). Justified because they were selected by the Heart of Kandrakar itself, a magical artifact that reasons in a different way than humans do and is implied to have selected the best five for the job out of the whole planet Earth—no matter their previous relationships (of the five, only Irma and Hay Lin are shown to be already friends when selected a year before the series) or where they lived (Will and Taranee are from two different cities, and the prequel issue shows the Heart's magic subtly leading to them moving to Heatherfield).
- Advice and Trust: Shinji, Asuka, Rei and Hikari are fifteen-year-old mecha pilots. Asuka often complains that everybody demand that they act like mature adults when they are on duty... and at the same time Misato will not let Shinji and her sleep together because they are just teenagers.
- Child of the Storm subverts it - Harry and his friends are a group of young teens who end up in phenomenally dangerous situations, but they tend to be either caught up in them entirely by accident or pretty much recruit themselves. Notably, their parents/parental figures are decidedly unhappy about this - and it has to be said that the kids aren't always that happy about it either.
- Then Doctor Strange plays it straight as an arrow in chapter 75 when he recruits them to use the cover of the New Avengers' assault on HYDRA's base to sneak in and rescue Steve, Tony and Bruce.
- In Thousand Shinji, Shinji, Asuka and Rei are teenagers, Humongous Mecha pilots... and pretty psychotic.
- All pilots in Children of an Elder God are teenagers. Asuka is thirteen and their teammates are fourteen. Several of them –like Asuka or Touji- are quite hardheaded, to boot.
- In The Second Try:
- Played straight with Rei, who is a fourteen-year-old mecha pilot.
- Subverted with Shinji and Asuka. Everyone believes that they're teenagers, but due to time-travel shenanigans, they're in their early twenties.
- Neon Genesis Evangelion: Genocide: Shinji, Asuka, Rei, Touji and Keiko are all fourteen-years-old Humongous Mecha pilots.
- In Last Child of Krypton, Shinji Ikari, saviour of mankind and the most powerful human in the planet thanks to his Kryptonian DNA, is fourteen. Asuka is a thirteen-year-old Humongous Mecha pilot, and an Amazon (a Kryptonian in the redux). Touji is fourteen, and he received a Green Lantern, the most powerful weapon in the universe...
- Once More with Feeling: Shinji, Asuka and Rei are fourteen-year-old mecha pilots... and the former two have plenty of bad attitude.
- Subverted in the Power Rangers fanfic Power Rangers GPX. The GPX Rangers were specifically trained to take on an alien threat before it actually occurred. At the time of the story, many of them are either in college or even had jobs or careers before their Ranger lives took over. Only one is specifically stated to still be a teenager.
- Partially subverted in Power Rangers: Oceania. Unlike Power Rangers GPX, though, Kanohi basically empowers the first few that come to his temple: a fisherman, a lieutenant commander in the U.S. Navy, a lifeguard, a doctor, and a college student/hula teacher. Only one of these may be a teenager, but not all.
- Five teenagers get picked by an alien to save the world from an alien invasion. They're eventually joined by the alien's younger brother, himself a teenager. To its credit, the series does deal with the absurdity of five teenagers being the world's only hope, and in the end they're all shown to have some fairly deep psychological trauma. Initially explained that said alien didn't have much choice, since he was about to die and the kids happened to be there.
- However, it is later revealed that a Sufficiently Advanced Alien Energy Being (read: stand in for God) hand-picked more than half of the kids for various reasons; since it is involved in an absurdly complex universe-spanning game with an evil Sufficiently Advanced Alien, the earth's defenders being teenagers might have been a restriction as part of one of the in-game deals.
- The Andalite Chronicles has another explanation: experience had taught Elfangor that human children were capable of much more than one might think, based on his teenage human love interest Loren (and he himself was a teenage Andalite during the events of that book).
- When the Animorphs gain the ability to increase their numbers, they seek out more teenagers. Because they figured teenagers adapt to new situations more quickly than adults, and that teenagers would listen to them and be happier to let them take the lead than adults would; in addition they deliberately seek out disabled kids as there's no way the Yeerks would be using them as hosts.
- A literary example, the new The Hardy Boys series, Undercover Brothers. Frank and Joe are members of a crime group composed of teenagers, ATAC (American Teens Against Crime). The reasoning behind it is that teens can go places and ask questions that would be suspicious if asked by an adult.
- In Ender's Game, the Battle School recruits kids as young as 6 or 7, where they are examined for strong willpower and survival instincts. This is justified in-universe, because no one old enough to understand war and with enough compassion to be a great general will fight it. Like in Animorphs, the kids end up very, very messed up. And the fallout is that in the Ender's Shadow sequel series, many of them try to take over the world. Ender's older brother recruits some of them on his side and does conquer the world.
- While they didn't exactly recruit them, the rebellion in The Hunger Games series doesn't get off the ground until Katniss and Peeta (mostly Katniss, who has a lot of attitude) defy the Capitol while also gathering enough public adoration that the Capitol is reluctant to punish them directly, essentially making them figureheads for the rebels.
- In the Lost Books series, Johnis, Sylvie, Billos, and Darsal, on multiple occasions.
- The Other Light members in the Left Behind book Kingdom Come are all physically teenagers and young adults under 100 years old looking for recruits of the same age range so that they could pass on their teachings before they die at 100 to the generation that will confront God and Jesus at the end of the Millennium...only to get seriously owned!
- In The Tripods, this is the only option because most people over 14 are Capped and mind-controlled.
- Also the situation in The Resisters series by Eric Nylund. Humans are absorbed into the Cha'zar collective at puberty. The adults running the resistance stay underground and are unaware of other adult resisters until the third book.
- TimeRiders plays with this trope. The main cast are all thirteen to nineteen, as one would expect from this trope and teen to young adult fiction generally. However, they were chosen because it was known exactly when and where they were to die, and invariably dying in such a way that the body could not be recovered, enabling them to be snatched from the jaws of death easily. Also, all three had skills well suited to the tasks they would perform in the group - initiative, data-mining and a keen eye for tiny changes in detail. They also take a hulking great combat unit along on missions for when tactical evaluation or martial prowess are required. They are also purpose built organic robots who are slightly more resilient than ordinary humans anyway, and thanks to Liam's time in the past on missions he's closer to twenty by now and pushing the definition of 'teenager'.
- The Daemon in The Hearts We Sold deals with teenagers exclusively, and doesn't seem to have anyone older than eighteen on his payroll. This turns out to be because anyone younger than fifteen or sixteen is too much hassle to work with, but the older you are, the less likely it is that your body can handle a fight with a monster. Even teenagers have no guarantee of surviving, but their odds are the best.
Live Action TV
- Power Rangers:
- Mighty Morphin' Power Rangers: the Trope Namer. In the pilot, mentor Zordon asked for "five overbearing and over-emotional humans" in the area, and helper robot Alpha said, complete with facepalm, "Oh no, not that! Not... teenagers!" to which Zordon responded, "that's correct Alpha," to which Alpha sighs, "I was afraid of that." Only one of the group didn't have any martial arts training and they were fairly decent shots on the very rare occasion when they actually used their blasters. The reasoning behind this, stated in the first episode, was that as teenagers they would be the generation to inherit the planet, and thusly should be the ones who protect that inheritance. Power Rangers Turbo would later make it a plot point in order to justify a cast shakeup; the older Rangers from Mighty Morphin' were dismissed from Ranger duty and replaced so they could begin establishing normal grownup lives. (Also, these "teenagers" definitely are NOT as Zordon described them. They're neither angsty nor overbearing.)
- The rest of the Power Rangers franchise downplays this, however. Many seasons justify teen heroes by either having them already in training to fight evil when said evil emerges (Ninja Storm, Jungle Fury, Samurai) or the only ones in the vicinity to have powers (Dino Thunder, Mystic Force, Dino Charge). The third common setup narrowly averts this trope, as there the Rangers are usually twentysomething adults and, while not military, are specifically recruited for the skills that they do have (Lightspeed Rescue, Operation Overdrive, Ninja Steel).
- Power Rangers Megaforce, being a deliberate homage to Mighty Morphin', brings this trope back in full force. Gosei is a bit more diplomatic than Zordon, though, asking for "energetic and unstoppable" humans, but his Robot Buddy still verbally facepalms at teenagers much like Alpha did.
- Mighty Morphin' Power Rangers: The Movie (an alternate continuity, but still interesting) implied that Zordon had been recruiting teenagers for centuries. Ivan Ooze remarks with disgust that "Zordon's still using a bunch of kids to do his dirty work" when he meets the current team, and clearly hates teenagers even more than he hates humans in general because of it.
- Power Rangers (2017) changes the original origin to the five teenagers stumbling on the Power Coins and Zordon's ship. Zordon himself is actually quite skeptical about their capabilities for most of the movie.
- Kousoku Sentai Turboranger from Super Sentai is probably the Trope Codifier, as it's the first Sentai team to consist of just teenagers, but they've yet to be referred as 'Teenagers With Attitude' (this was before Power Rangers was even conceived in its current form).
- Mighty Morphin' Power Rangers (Boom! Studios), set in its own continuity inspired by the series, presents a justification for this trope, at least with regards to the teens themselves: Prior to the 1993 team, Zordon had recruited a team back in 1969. This time, they were all capable adults, but they had to be pulled from different parts of the world and walks of life. The end result is that while sufficiently skilled to be combatants, they hardly got along, for the most part. Two of them were at odds for having different opinions about the Vietnam War, and one was a KGB specialist, a proud Soviet, and thus, displeased at the notion of following the orders of an American. Worse than that, the team is simply thrown into the fray on the moon without much in the way of team building exercises or the like, and thus, when confronted with the awakened Psycho Green, two die horribly, and the KGB specialist dies taking out Psycho Green, although he at least makes peace with Red before passing. Zordon realized his folly, especially after being chewed out by the surviving two, and thus, when he recruits the present team, he would choose a group of close friends, high schoolers as they may be, who had the strong capacity for teamwork over skills that could simply be developed with training and time.
- Buffy the Vampire Slayer: Averted, mostly. Most of the Scoobies weren't exactly recruited - they were just swept up in events. Anya and Tara were genuinely recruited, but they had extensive knowledge of demons and magic, respectively (and in Anya's case, was over a thousand years old despite physically being a teenager). Also, in later seasons, they stopped being teenagers. Slayers though are always chosen from teenage girls, and few of them live past 18. About the only explanation for this is that the creepy old men who created the Slayer role figured younger girls would be easier to control or they lived before "teenager" appeared as a concept and what is now a teenager was considered an adult.
- Justified in The 100. The Ark space station decides to send one hundred people down to the Earth's surface, ostensibly to see if the planet is livable again after the nuclear war, but really because the Ark is running out of oxygen, and sending the 100 down frees up more air for the rest of the population. Since almost everyone expects the 100 to quickly die of radiation poisoning, the plan is to only send down expendable criminals (with the promise of a full pardon if they survive). However, since any adult who breaks the law gets an automatic death sentence, the only criminals they have handy are their juvenile delinquents. Cue one hundred rebellious teenagers being sent to recolonize the Earth.
- Class (2016): The Doctor trusts a bunch of six-formers to look after a rift in time at their school (which is largely due to him dropping in there too often). Deconstructed as the psychological strain has some realistically traumatic effects on the characters, and they end up committing a genocide that might have been justifiable to them (the aliens in question were by all experience Always Chaotic Evil and implacably hostile to humanity and them in particular) but would probably horrify the Doctor if he found out about it.
- Bleak World has the Androids, who are all cyborg teenagers brought back from the razor's edge of death. They are also the most dangerous of the Experiments, due to being completely batshit.
- Many City of Heroes players make their in-game avatars as teenagers.
- Ditto Champions Online players.
- EarthBound's four main characters are teens (and possibly even younger in the Japanese version), though they were chosen by a prophecy. Unlike many examples, though, the trope is deconstructed, since what the characters have to go through at the end of the game is meant to signify a loss of innocence.
- Lampshaded in Golden Sun, when this is one of the objections the adults of Vale have to the Wise One (and the High Elder) insisting that only Isaac and Garet can chase down the Mars Clan warriors to recover the Elemental Stars. Possibly justified when we learn they're not meant to thwart the return of Alchemy, but rather, to gauge the necessity of it, which the elders of Vale already proved unwilling to do.
- Par for the course in the Shin Megami Tensei: Persona series, where most of the party members are high school students. This is downplayed in the Persona 2 duology, where Innocent Sin has one adult in the core lineup and one adult Guest-Star Party Member, and Eternal Punishment has the entire team consist of adults except for one guy, who has a very good reason to be there. The trope is justified in Persona 4, where the party consists of Amateur Sleuths and near-victims of the Serial Killer who can't go to the police because nobody would believe them, and in Persona 5, where the heroes are social outcasts explicitly rebelling against corrupt adults.
- In El Goonish Shive Susan and Nanase got their magic potential unlocked this way, when two immortals recruited them to fight an aberration (a dangerous vampire-like being). This encounter led to 15-year-old Susan getting some long-lasting psychological scars due to being forced to kill someone who used to be human. It later turns out the immortals in question had no legitimate need to do so as they could have called on several more experienced sources to neutralize the threat. The fact that they convinced teenage girls to handle it alone was a source of great disgust to Jerry, another immortal.
- Mocked in Manly Guys Doing Manly Things here, where the Commander delivers to Zordon teenagers with the modern definition of attitude instead of the 90's upbeat and "can do" attitude Zordon actually asked for (the definition of "attitude" as pertains to teens having shifted back and forward rapidly ever since the end of WW2).
- Parimetra: Averted in the present day, with all the superheroes being 19 or 20 years old, but the flashback chapter reveals that when A.S.H. was created, its members were 13 or even 12. Yikes. Justified, as they're the only people able to defeat the monsters, adult or otherwise.
- In Homestuck all SBURB/SGRUB players are around 13 when they enter the game, though depending on the shenanigans that happen in their session, they might grow out of the "teenager" part. Caliborn was only 11 and he definitely had the most "attitude" out of any character
- Naturally any weird Power Rangers parody "must include teenagers with attitude."
- At the end of that video we get a shot supposedly inside Zordon's Lab, which has been trashed to hell with graffiti. "This is why I never let teenagers with attitude into my lab!"
- Sailor Nothing also deals with the absurdity of choosing teenage girls to save the world. Who would come up with such a ridiculous idea? A villain who actually wants the good guys to lose?
- The line is parodied in My Way Entertainment's own Mighty Morphin' Power Rangers parody:
Zordon: "ALPHA! That bitch escaped! Bring me five motherfuckin' teenagers with five motherfuckin' attitudes!"
- Lampshaded HARD in the grim-n-gritty Power/Rangers "deboot", where Rocky laments that if Zordon really WAS one of the "good guys", he would have never made teenagers fight in an intergalactic war that they couldn't possibly hope to comprehend, and that the Rangers have no right to take the moral high ground on anything after that. The former rangers' messed up and/or tragically cut-short lives are a testament to this.
- The various Huntsmen and Huntress Academies are certainly in the market of recruiting particularly badass teenagers with attitude to help defend people from the Grimm, a race of eldritch horrors hellbent on exterminating humanity. Ruby got into Beacon after one of the teachers watched her inflict a Curb-Stomp Battle on a crime lord and his goons. The adults who did the recruiting didn't exactly plan on the kids being the first line of defence against a malicious conspiracy against the kingdoms, however...
- In Volume 2, this trope is deconstructed somewhat; Ozpin, as fantasy teachers are wont to do, allows team RWBY to investigate an area that may be the villain's hideout and definitely is full of Grimm. Ultimately, the girls end up triggering a breach in the kingdom's defenses that nearly leads to an invasion of Grimm. While the problem is solved quickly, the events disgrace Ozpin.
- Volume 3 goes further with the deconstruction; realizing that the villains aren't finished, Ozpin asks Pyrrha Nikos, The Ace of Beacon, to inherit the power of the Fall Maiden and become the savior of mankind. However, said inheriting relies on an experimental and dangerous machine that may destroy Pyrrha's identity, causing her much angst on whether or not she can go through with it. In the end, she's unable to accept the power before Cinder steals it for herself. Pyrrha attempts to fight Cinder, but all she accomplishes is dying, which causes Ruby to awaken her own latent powers.
- In Worm we have a rare villainous example: supervillain Coil assembled the Undersiders from a group of teenage solo villains that would have never thought to work together otherwise.
- The Trope Namer is discussed in the Death Battle episode between the Power Rangers and the Voltron Force as Wiz flat out calls is "asinine", yet somehow impressed that it actually worked. This was vastly different to the Voltron Force, who were already space explorers (or the last survivors of Earth, if you go by GoLion.), thus a lot more trained and a factor into the Rangers' ultimate defeat.
- Avatar: The Last Airbender: The Gaang never picks up anyone over the age of sixteen. Justified in the beginning as Katara is pretty much the last person on the planet who still believes "the Avatar will return" - and later that all the adult warriors get themselves captured and/or killed. An alliance of Cool Old Guys shows up for the finale, however.
- Likewise, in the beginning of The Legend of Korra, the main characters are older, being roughly 16-18 years old, but are still teens. A three-year Time Skip for the fourth season changes this, however.
- Korra generally avoids this, as despite the 'gang' being all teens, the older mentor characters get just as much screen time and character development. They still all fit with the creator's admission that no one between the ages of twenty and forty is worth a damn though.
- Captain Planet and the Planeteers had Gaia recruiting five teenagers with no previous experience fighting evil. On the good side, they were able to summon a superhero when things got too tough. The Planeteers were the generation that was going to grow up to inherit a polluted planet, like the intended audience, so it made sense for Gaia to teach people of that generation to take care of it.
- Double Subversion with the Storm Hawks, as when they tried to register the first time, they were turned down for being too young (with the exception of Stork). Eventually, they are recognized by the Sky Council as Sky Knights.
- Also lampshaded as many secondary characters comment on their ages for about the first dozen episodes.
- At one point several other kids tried to join the team as well, but were ultimately encouraged to return to their homes for awhile.
- Played straight in the new Hot Wheels Battle Force 5 animated series. When one of the six teens rather sensibly ask their holographic advisor why they alone were chosen to save the world, she replies that each one brings "something different" to the team. Which one brings driving experience to a battle for the fate of the world that involves high-speed racing is never said.note
- The Animesque Totally Spies!. Think Power Rangers meets Charlie's Angels.
- Explained as the reason why the Mother Planetoid adopted the BRATS Of The Lost Nebula and gave them the equipment they needed to battle the Shock forces, as the Planetoid's creator believed that only teenagers and their chaotic nature could outmaneuver the Shock's forces.
- While most of the cast is, surprisingly, grown up in Generator Rex the title character and protagonist, Rex is 15, and working as the top agent for a N.G.O. Superpower. Completely Justified thanks to his High Level Super-Powers, the most important of which is Permanent Power Nullification in a world overrun by superpowered, often mindless mutants.
- The main cast in Code Lyoko is entirely made of teenagers (though one of them is technically in her twenties, retaining a teenager's body and personality due to being trapped in a virtual world for eleven years) who regularly use a highly advanced computer to go on a virtual world and fight a powerful evil AI. The trope is justified, however: the recruiter (Jérémy) was a teenager himself, and he has to rely on his friends because if he had gone to ask for adults' help, they would have 1) Shut down the computer without leaving him time to free Aelita from it and 2) Probably seized the machine and used its extremely dangerous tech for unhealthy purposes. Plus, whenever the heroes try to rely on adults for help, it almost always ends up with Adults Are Useless in application. And even when it doesn't, they always lose their memories thanks to the supercomputer's Return to the Past program.
- Exaggerated and justified in Ben 10, where the Omnitrix, a watch-like alien device known as the most powerful weapon in this universe, was actually intended for experienced Retired Badass Max Tennyson. However, his 10-year-old grandson Ben happened to find it first, and his DNA was close enough to Max's to have the Omnitrix take him as its owner; after that, the Omnitrix being a Clingy MacGuffin, Ben is unable to remove it and the error cannot be undone. By the time it can, Max has convinced the Omnitrix's creator Azmuth to let Ben keep it, believing the kid has potential.
- Justified in Voltron: Legendary Defender. Allura wakes up from a ten-thousand year cryosleep to discover that her entire species has been wiped out and that a Garla ship is on its way to Arus to destroy what's left, so she has to settle for the Ragtag Bunch of Misfits that stumbled upon her castle-slash-spaceship to assemble Voltron and save the day. She is, however, wise enough to pass over the Rookie Red Ranger and instead appoint the one responsible adult in the group as The Leader, Law of Chromatic Superiority be damned. Additionally, while four of the five Paladins are bickering teenagers, they were also military academy students prior to getting stranded on an alien planet, and thus at least have some training in aeronautics, engineering and hand-to-hand combat.
