History Main / JustAKid

** ''Tamers'' wasn't the only season to have a JustAKid situation. Iori/Cody got this treatment from his older teammates, two of whom (T.K./Takeru and Kari/Hikari) conveniently forgot that Iori/Cody is two full years older than they were during their first adventure with the Digimon (at least that's the age gap in the American version. Correct me if that isn't universal).
** Issuing requested correction: Iori is ''one'' year older than Takeru and Hikari were when their adventures began.

** Subverted with gleeful enthusiasm in ''WebVideo/DragonBallZAbridged'' whenever they can get some footage to support it.
-->'''Gohan:''' I'm not going to back down. I might be younger than you, smaller than you, weaker than you, and much less experienced, [[BrickJoke but I learned more about peach farming than you... ]] [[ThisIsGonnaSuck I think this was a horrible decision.]]
-->'''Recoome:''' [[PreAssKickingOneLiner Recoome agrees.]]

* Underestimating a KidHero? How about a kid VILLAIN? [[BrainyBaby Stewie]], from ''WesternAnimation/FamilyGuy'', shows signs of developing into a DiabolicalMastermind, yet his parents tend not to take him seriously. For example, he likes to read books like ''Literature/ThePrince'' and ''Literature/TheArtOfWar'', yet his mother interrupts him telling him those books are not for toddlers and he should be watching ''Series/{{Teletubbies}}'' instead. (Of course, he somewhat likes the show, but still...)

* ''Series/GameOfThrones'': [[BadassGrandpa Tywin Lannister]] dismisses the 18-year-old [[YoungAndInCharge Robb Stark]] as a threat because of this, figuring that he'll probably run back home to the North at the first sight of battle. Even Robb's father is concerned. [[spoiler:He is oh so very wrong. When the dust settles, his son is a prisoner of war, and half his army has been destroyed. Turns out that Robb is actually quite the tactician.]] Ironically, the Reynes of Castamere once thought the same of Tywin.

* In ''ThePenguinsOfMadagascar'' Skipper has used this phrase regarding Private a couple of times, sometimes to him, and sometimes when being a LargeHam. The best was in "Caught In The Web" when Private was taken away by Alice...

* The Girl part of ''Manga/GunslingerGirl'' means that this is the usual reaction to them, even from people who have heard of their existence. The gunslinger part means that said people die soon after making this mistake.

* ''Manga/FullmetalAlchemist'': Lieutenant Ross and Sergeant Brosh lecture Ed and Al on how their youth means that they should give adults some more responsibility in the story. Of course, Ross is effectively shut down by Maes Hughes, who, GenreSavvy man that he is, knows who the main characters are.
** Ed takes it quite well (despite [[HotBlooded his temper]]).

* Iris from ''Anime/{{Pokemon}}'' has a rather odd habit of calling [[TheHero Ash]] a kid whenever he says something she doesn't like or does something stupid...[[HypocriticalHumor even though ''she's'' a kid herself!]]

-->'''Dawn:''' [[CrowningMomentOfFunny It's like a meat party in my mouth]]. ''(pause)'' [[ThatCameOutWrong Okay, I'm just a kid and even I know that sounded wrong]].

* ''WesternAnimation/JusticeLeague Unlimited'': Spoofed when Flash laments the rest of the League's reluctance to take him seriously... while playing Rock'em Sock'em Robots. It's also played straight in the season finale when Flash answers [[FanNickname Luthorac's/Brainthor's]] taunt of "Are you going to fight me, ''boy?''" by [[LetsGetDangerous deciding to get dangerous for once.]] [[CrowningMomentOfAwesome Epically.]]

** In ''VideoGame/MegaManZX Advent'', Atlas, the Mega ([[ViewerGenderConfusion Wo]])Man Model F, tells young Thetis, Mega Man Model L and fellow member of a QuirkyMinibossSquad that he's just a kid like The Hero Grey/Ashe, the new Mega Man Model A and wonders why so many kids were chosen to be [[TheChosenOne Biomatches]] [[note]]The [[TransformationTrinket Biometals]] are the {{Legacy Character}}s of [[VideoGame/MegaManX X, Zero]], [[VideoGame/MegaManZero X's Four Guardians, and Dr. Weil]], FYI.[[/note]] Slightly irked, Thetis is quick to mention that as a teenager, there isn't much of a gap between them age-wise.

** In ''VideoGame/MegaManZX Advent'', Atlas, the Mega ([[ViewerGenderConfusion Wo]])Man of Fire, tells young Thetis, Mega Man of Ice and fellow member of a QuirkyMinibossSquad that he's just a kid and wonders why he was picked to be Model L's [[TheChosenOne Biomatch]] [[note]]The [[TransformationTrinket Biometals]] are the {{Legacy Character}}s of [[VideoGame/MegaManX X, Zero]], [[VideoGame/MegaManZero X's Four Guardians, and Dr. Weil]], FYI.[[/note]] Slightly irked, Thetis is quick to mention that as a teenager, there isn't much of a gap between them age-wise.

* Downplayed in ''FanFic/BuildYourWingsOnTheWayDown''. Hughes is horrified that Edward Elric, an unsupervised and unaccompanied eleven-year-old child is joining the military. However, he respects Edward's intelligence and capabilities too much to say it to Edward's face. Hughes instead tries to support Edward and lashes out at Roy, who Hughes believed should have known better than make a ChildProdigy into a [[Child Soldier ChildSoldiers]].

* In ''Fanfic/{{Transcendence}}'', almost everyone on Azeroth who first meets Ichigo tends to doubt or outright dismiss his competence because he's only a teenager. It usually doesn't last long.

** It also comes up when the Justice League discovers that one of their own members, [[{{Shazam}} Captain Marvel]], is [[OlderAlterEgo actually only ten]], leading to a vote about whether or not to keep him on. [[spoiler:They do]].

* This was the main plot of ''TheSpongebobSquarepantsMovie''. [=SpongeBob=] got this from nearly everyone in the movie as a reason he's not capable of doing what he sets out to do. Of course, he does prove himself.

* Ryuu of ''Manga/AkagamiNoShirayukihime'' is underestimated and frequently thought to be some kind of messenger or assistant when faced with patients who are unfamiliar with him since he managed to become a pharmacist at the age of twelve. Those patients that have heard of him have an unfortunate tendency to find him creepy due to unfounded rumors which flourished due to his age, quiet behavior and lack of social skills.

** David was told by King Saul that he was too young to take on Goliath the Gittite by himself. David told King Saul that he had slain a lion and a bear with God's help while still just a youth, and with God's help he will also be able to slay the Philistine giant.

* ''Manga/DogSoldier'' has 7-year-old [[JustAKid Morita Asao]]: Has Hiba and Fudo to save his father, parachutes out of the plane, then, after his father is killed in front of him, sneaks a grenade into the prison, and walks THROUGH fire to stop Gaddafi's ICBM.

* {{VideoGame/Bastion}} has this Averted, as the main protagonist is not only the one of the few survivors of {{The End of the World as We Know It}}, but he's Only 16 or so. Then he gets {{More Dakka}}. A hammer, shotgun, rifle, bow, flamethrower, machete, spear, indestructible shield, and an OP cannon. More than Enuff Dakka for such a young Kid, huh? Even the Narrator thinks so.
--> Rucks: (Kid uses Army Carbine and [[spoiler:Calamity Cannon]]) "Kid makes me nervous sometimes strutting around with all those guns."
** It gets better. Yup. {{Macross Missile Massacre}}
---> Rucks: (Kid uses Galleon Mortar and [[spoiler:Calamity Cannon]]) "OK, now that's just plain overkill. I mean, come on."
** But then again, in a vague spoiler, he did [[spoiler: lose a lot through his early life at the Rippling Walls]]. {{Deus Angst Machina}} Much?

* ''FireEmblem''
** Played for laughs in ''[[VideoGame/FireEmblemJugdral Fire Emblem: Genealogy of Holy War]]'':
-->'''Sylvia''': ''My name is Sylvia, but you can call me 'Sylvie'!''\\
'''Sigurd''': ''Huh? Just a little girl. You better find a place to hide, it's dangerous here.''\\
'''Sylvia''': ''Little... GIRL!? You ever see a little girl with [[GagBoobs THESE!?]]''
** A couple of instances in ''[[VideoGame/FireEmblemElibe Binding Blade]]''. A few characters privately express doubts about TheHero Roy, since he's only fifteen and wound up commanding a RagtagBunchOfMisfits because of his father's illness and his allies' treachery, but their doubts are soon assuaged. Lugh, a ChildMage, also gets this from a few characters since he's younger than Roy and (unlike his twin or adopted brother) doesn't have a cranky attitude to make up for his youth.

** Also played straight with Rolf in [[VideoGame/FireEmblemTellius the Tellius games]] (less so in ''Radiant Dawn'' since [[TimeSkip he does get older]]) by his brother Boyd, and the majority of the people on his support list, excluding the [[IllBoy sickly priest Rhys]] and his mentor [[TallDarkAndSnarky Shinon]], for the most part. Some of his support conversations basically begin with someone telling him that he's too young to be on a battlefield, [[BerserkButton while he denies it vehemently]], and later proves them wrong at the A support level.
** [[TheHero Ike]] has this attitude when Mist joins along with Rolf in chapter 9. He quickly gets over it, though he remains protective throughout the rest of the two games. Justified in that she's his only living blood family left.
** Muarim says something to this effect if you send Rolf, Sothe or Mist up against him, distressed at the idea of kids being sent off to battle.

** Arden from ''Geneaology'' is shocked to see [[Really700YearsOld Nowi]] on the battlefield for this reason.
** In the VideoGame/FireEmblemAkaneia games, [[TheHero Marth]] gets this often.

* Literature/HarryPotter saves the day about once a year, but the good adults, with the exception of [[ReasonableAuthorityFigure Dumbledore]], treat him like a child until the sixth book or so. In particular, using this trope was [[MisplacedKindergartenTeacher Umbridge]]'s ''modus operandi''. To be fair, even disregarding the number of near-death experiences, hairs-breadth-escapes, and hideously one-sided battles Harry's had to face, you can't blame the adults for trying to prevent him from getting blown up or having his soul sucked out.
