->''"The power to stick my fingers into a person's nose and make them fat!"''

''The Law of Ueki'' is a manga series created by Tsubasa Fukuchi that was adapted as an anime. The story basically starts out when Mori Ai thinks that her classmate, [[TheDeterminator Ueki Kousuke]], is an alien. Not quite, but he does have the [[GreenThumb power to turn trash into trees and control them]]. This power was given to him by their teacher, a God Candidate involved in the [[TournamentArc Battle of the Supernatural Powers]], a tournament to decide who will be the next [[KingOfAllCosmos god of Heaven]].

Each God Candidate -- a hundred in total -- is required to choose a junior high school student to act as their fighter for some unspecified reason. Each candidate then [[TouchedByVorlons bestows their chosen student with a certain power]]. Of course, every given power ranges from [[WhatKindOfLamePowerIsHeartAnyway weird]], [[BlessedWithSuck near useless]], [[BlessedWithSuck potentially self-hazardous]], to AwesomeButImpractical. The winning God Candidate will become the new boss of Heaven and the winning student will receive the Blank Zai (or talent), a talent that can be anything they choose.

Naturally, this leads many students to thoughts of greed and selfishness. Being TheHero, Ueki decides to take it upon himself to win this tournament to keep that power away from those that would abuse such a gift, fighting for justice with Mori Ai in tow. Along the way they meet not one, but two [[CreepyMonotone creepy]] [[BigBad major enemies]], gather a loyal group of TrueCompanions, discover that Ueki is a Heavenly Being, stumble upon some sort of [[AncientConspiracy ancient heavenly conspiracy]], and indirectly promote recycling and environmentalism (uh, well, sort of).

Followed by the manga-only The Law of Ueki Plus (or The Law of Ueki+). Ueki and friends appear in the MassiveMultiplayerCrossover game, VideoGame/SundayVSMagazineShuuketsuChoujouDaikessen.
!!''The Law of Ueki'' provides examples of:

* AGodAmI: The goal of each Celestial Candidate is this.
* ALadyOnEachArm: God.
* AintNoRule: Part of a BatmanGambit by the current King. [[spoiler:He deliberately set up the rules so they did not specifically ban Celestial or Infernal children being chosen to fight, knowing that this would cause some of the King Candidates to think they were getting away with something by inserting "ringer" champions. It didn't turn out quite as well as the King hoped.]]
%%* AncientConspiracy
* ArmCannon: The Kurogane, the 1-star Sacred Weapon, is a giant cannon strapped to the arm.
* ArtEvolution: While the art style of the manga may appear a bit strange throughout, there is a very noticeable improvement from the style in the first chapter to that of the later chapters.
* {{Autodoc}}: Heavenly Beasts release a healing machine which fully restores anyone inside it for exactly 12 hours. However, if the healing process is interrupted in any way and the machine is damaged, the person inside it will die.
* AwesomeButImpractical: Some powers and a lot of the Zai Ueki seems to get. Cheering Zai, anyone?
** Ueki's [[BoobyTrap Gulliver]]. Used successfully exactly once. He seems to be aware of this fact and uses it to figure out his opponent's power.
** [[TheChick Mori]]'s power is basically [[GameBreaker completely unstoppable]] once it activates, but [[AwesomeButImpractical its limiting condition is downright]] ''[[AwesomeButImpractical absurd]]''. She mopped the floor with both of the enemies she tried it on... but it doesn't work unless the enemy is in a certain pose. 90% of the enemies in the series wouldn't be caught ''dead'' in that pose.
* AwesomeByAnalysis: Once Ueki figures out your power, you've lost. Same goes Sano. Although the fact that most of the power-users are stupid enough to [[CallingYourAttacks tell their opponent about their power (right up to their limitations)]] didn't helped much.
* AwesomenessIsAForce: Maoh / [[DubNameChange Arch-Enemy]], the 10-star Sacred Weapon. [[HeroicWillpower It takes up the form and power of its user's will]]. [[TooAwesomeToUse It can only be used six times in a lifetime, though]].
* BadassTeacher: Just because Kobayashi is [[ActualPacifist against violence]] doesn't mean it's a good idea to pick on his students.
** Inumaru also lampshades it at one point, surprised that someone so conniving but loves justice so much went into teaching junior high school.
* BagOfSpilling: Between Law of Ueki and the short five volume manga sequel Law of Ueki Plus. Justified, as if Ueki uses any of his old special abilities it would result in the loss of his Zai and he would die, because the tournament is over and therefore nobody is a combatant now.
** The strange part is that 9 from his 12 powers were weapons, and one is a Cancelator, but he has also some JetSkates, and a pair of wings. Also, he could try to use his powers in a way that wouldn't harm anybody.
* BadassNormal: Mori, since her power is pretty much useless and has only been used twice in the whole story. It's justified that her limitations is ridiculous (goody-two-shoe pose, anyone?). But when she fought in Dogura Mansion, it has been shown that she had fought to a tie with Kabara, who's an assassin to boot.
** Moreso: Li Ho, who never ever uses his ability.
%%* BatmanGambit
* BerserkButton: It's not a very good idea to [[http://www.mangafox.com/manga/law_of_ueki/v14/c000/66.html insult Rinko]].
* BerserkerTears: [[spoiler: Marilyn, after Ueki exposes her DarkAndTroubledPast]].
* {{BFS}}: The Ranma, the 3-star Sacred Weapon, is a big ass sword stuck to the user's arm.
* BlessedWithSuck: a lot of the powers have rather detrimental parameters for them to work(one has to hold one's breath, keep hands in pockets, hold hands, ''give up a year of life per usage''...)
* BlindWithoutEm: Averted by Mori, who only needs her glasses to read.
* BlueWithShock: [[spoiler:The ''entirety'' of Team Ueki experience this when Rinko snaps during her match.]]
* BoobyTrap: The Gulliver, the 7-star Sacred Weapon, is a box that appears from the ground to capture the user's opponent in 0.5 seconds. Any attacks directed at the walls while inside will be deflected. It can be destroyed with other Sacred Weapons, however.
* BossSubtitles: For every opponent.
* ButNotTooForeign: Rinko is implied to be half-Japanese.
* ButtMonkey: the creator said so himself that Inumaru exists to be bullied by Kobayashi. [[spoiler:Although subverted nicely in the end, when [[ThrowTheDogABone the kids decide to name him as the next god.]]]]
* CallingYourAttacks: Ditto for nearly every power user in the series. Usually in the form of:
-->'''Power User''': The power to turn <thing> into <another thing>!!
* CapeWings: Kabara's ability is to turn his cape into wings.
* ChewToy: Ueki gets into a ''lot'' of situations that end up with him getting hurt in some way. Mori Ai even notes that this happened to Ueki even before the tournament started. Although most of those were the fault of Ueki's brashness, a lot of random events also seemed to be detrimental to him. It is later explained that this was due to the loss of a good luck zai of some sort.

%%* ConspiracyRedemption
* CreepyChild: Robert and Anon, both of who mostly talk in CreepyMonotone.
* {{Determinator}}: Ueki. In fact one of his opponents is defeated by his determination.
* DiscardAndDraw: Ueki loses all his abilities at the end of the manga. In the sequel he gains a new power: The power of "grabbing" in the form of "a mop".
* DisproportionateRetribution: The punishment for a god candidate helping their junior high school student in a battle is to be put on celestial death row. Even if they only do it to save a kid's life.
* DudeLooksLikeALady: [[GenderBlenderName Margaret]], Anon, Kapucho, and Barrow.
* ElementsDoNotWorkThatWay: Real iron isn't nearly as strong as the iron that Sano can turn towels into.
* EvilChef: Marco Maldini, who can change tomatoes into magma. He is also very angry if you waste his soup.
* ExactlyWhatIAimedAt: Sano especially loves this tactics.
* {{Exposition}}: outrageous amounts.
* {{Fetish}}: [[spoiler: Mori's power gives her opponent a HUGE eyeglasses fetish...And then there's Kill Norton, who glued his glasses to his head. Granted, it was in case he got paired up with Mori so he could have a way to counter her power, but still... Also, his glasses are named Bianca. Later, he asks Mori to make him an eyeglasses lover again, so he can work up the nerve to go help his teammates fight Anon. The last time we see him, in the epilogue, he's muttering "Glasses... glasses... glasses..."]]
* ForTheEvulz: Anon helps humans then proceeds to harm them immediately afterward just to find out what kind of reaction he will get [[spoiler: (like rescuing a boy's puppy and trying to throw that puppy to an electric pole)]].
* FunnyAfro: Ueki temporarily gains one along with a Disco Zai ("talent to dress stylishly" in English). Apparently, Ueki was following the good ol' Saturday Night Fever style. He was immediately beaten up by Mori.
** And one celestial beast wears one near the end, and immediately gets a lampshade hanged on it.
* GenderBlenderName: Margaret is a girl's name, and Margaret [[DudeLooksLikeALady looks female]], but Margaret is definitely ''not'' a woman.
** An early volume of the Viz translation actually said he was a woman in the character profiles at the beginning.
* TheGenericGuy: Or girl. Mori (at least initially, before she gets BlessedWithSuck)
* GreenThumb: Ueki's power. A rare example of TheHero using this power.
* HeartIsAnAwesomePower: The premise of the whole show.
* HannibalLecture: Some of the less friendly God Candidates and team leaders are prone to these- and not just at the heroes.
* HappinessInSlavery: Rinko, who [[LoveMartyr loved]] Robert. Although, she does get out of it soon after meeting Ueki, [[HeelFaceTurn joining his group]].
* HungryWeapon: Mash, the 4-star Sacred Weapon, is a giant block with "eyes" and mouth that chomps the opponent to unconsciousness.
* HyperspaceArsenal: [[PhysicalGod Celestials]] have the Sacred Weapons.
* IdiosyncraticEpisodeNaming: All episode titles begin with "The Law of..."
* IdiotHair: Many characters. Some have 2.
* IdiotHero: while Ueki does have several brilliant insights, especially in battle, for the most part he seems rather simple-minded and clueless. On first meeting Tenko's gigantic dog-like form he thinks it's just a really big ''chicken'' of all things.
** This is actually {{Justified|Trope}} early on in the series, when Ueki loses his Study Zai ("talent to study") for attacking a non-combatant before the tournament begins.
* ImportantHaircut: Rinko's pigtails getting chopped off while protecting Ueki who is in healing process.
* IncrediblyLamePun: One of Ueki's opponents has the ability to change his IncrediblyLamePuns into reality.
* KingOfAllCosmos: The winner's God Candidate gets this job. The incumbent KingOfAllCosmos is a DirtyOldMan dressed in an unbuttoned button-down shirt, shorts, sandals, and wears a ten-gallon hat with CoolShades on it.
** And the new God is [[spoiler:a ButtMonkey]].
* KirkSummation: [[spoiler: The purpose of the tournament was so the King could try to get the Protectorates to see that times had changed and they had to stop living in the past and start looking to the future. He even gives a speech about it to the Protectorate controlling Margaret. It doesn't go as planned.]]
* LastMinuteHookup: Ueki and Mori officially become a couple at the end of ''The Law of Ueki Plus''.
* LethalChef: subverted in Mori's case. Her cooking looks [[AlienLunch disgusting (and alive)]] but [[TastesLikeChicken tastes very good]].
* LuckilyMyShieldWillProtectMe: The Hood, the 2-star Sacred Weapon, is a giant gauntlet spawned from the ground to protect the user from attacks.
* {{Meganekko}}: Rinko, Mori has glasses too ([[spoiler: and her powers are based around them]]) but she doesn't usually wear them over her eyes as she is far sighted and so they are reading glasses.
* MagicAIsMagicA: The setting is not consistent with those rules, though. It's explicitly said that every power has its limiting conditions. And yet not only some of the power users don't have any conditions: Sano, whose condition (holding his breath) is explicitly stated, [[TalkingIsAFreeAction freely talks while using his power]].
** One can argue, however, talking is still holding one's breath. You aren't inhaling, are you? It's obvious Sano further mastered his power past episode 2 (where he was explicitly shown HOLDING his breath in comedic fashion), but later on, he can talk and still use it, implying he's learned to control his breathing far better. He is also shown gasping for breath at the end of the Matthew fight.
* MentorOccupationalHazard: If a god candidate helps their student in battle in ''any'' way, [[DisproportionateRetribution they get sent to Hell and put on death row there]].
* OddlyNamedSequel: The Law of Ueki Plus
* OffModel: Happens relatively often in the manga. Some panels just look ''weird''...
* OfficialCouple: Ueki and Mori. While not explicit in the anime (although there are are a few subtle ShipTease moments) it is made clearer in the manga and becomes fully canon by the end of the sequel series, ''[[OddlyNamedSequel The Law of Ueki Plus]]''.
* OffscreenMomentOfAwesome: intentionally done twice, with characters describing how awesome a DangerousForbiddenTechnique was, after it was used ''off-camera''. It is then [[{{handwave}} explained]] as the result of a lack in special effects budget.
-->'''Sano:''' And my new special attack Magnetic Screw Choqa Zanbil didn't work at all.
-->'''Teammate:''' Yes, it was an amazing attack.
-->'''Subtitles:''' ((Please imagine the attack for yourselves))
* {{Ojou}}: Rinko, whose status and wealth had been exploited to no end by her schoolmates, leading her to join the Robert's Ten.
* OmnicidalManiac: Robert and Anon. Possibly Margaret.
* {{Portmanteau}}: The creator, fans, and most of the characters refer to Kobayashi-sensei as "Kobasen." (In English, it gets shortened to "Mr. K.")
* PowerGivesYouWings: The Seiku, the 9-star Sacred Weapon, are a pair of wings. [[AwesomeButImpractical The only catch]] is that most Celestials can't use more than one Sacred Weapon at a time, so they can't attack with their, say, Pick or Namihana while flying.
* QuirkyMinibossSquad: Robert's 10. Almost every team in Round 3 is another squad.
* RetractableWeapon: The Pick, the 5-star Sacred Weapon, is a giant column that shoots out of the user's hand.
* RuleOfSymbolism: Ueki's Maoh takes the form of [[spoiler: Kobasen/Mr. K, symbolizing his desire to protect his TrueCompanions, while Anon!Robert's is an EldritchAbomination symbolizing [[KillAllHumans his hatred for humanity]].]]
* ScaryShinyGlasses: seems to be Kobayashi's natural state, coupled with OpaqueLenses.
* ScrewThisImOuttaHere: Hideyoshi does this to Team Ueki at the end. Subverted however; he couldn't abandon his friends in the end, and by coming back at the last minute, [[spoiler:he saves Kosuke's life by getting knocked out by his Kurogane attack]].
* SinkOrSwimMentor: while Koba-sen, Ueki's God Candidate, has a strong sense of justice, he is laid back to the point that he pretty much leaves Ueki to figure out his powers by himself. To be fair, though, those are the rules. When he does step in to save Ueki from certain death--against the tournament's rules--he promptly suffers from the MentorOccupationalHazard. Though he doesn't die, he is [[spoiler:sent to Hell]].
** However, Kobayashi never told Ueki about the tournament, its rules, or the prize until after he'd already gotten into a fight. Everybody else knew all the specifics well before then.
* SnarkyNonHumanSidekick: Tenko, although he quickly loses his initial snarkiness and becomes more of a standard NonHumanSidekick later on.
%%* SplitScreenReaction
* SprintShoes: The Raika, the 6-star Sacred Weapon (although it's not so much a "weapon") are a pair of skates that let the user move really fast, but negates their ability to jump.
* SpoilerOpening: the second OP spoils quite a few things, most significantly the fight against Team Marilyn.
** The first OP makes it clear that Rinko will join the team, despite being initially presented as one of [[QuirkyMinibossSquad Robert's Ten]].
* StoryBreakerPower: Mori's power, which basically allows her to turn her opponents into eyeglasses fetishists, which is convenient because she wears eyeglasses. They become so enamored with eyeglasses that she can force them to knock themselves out just by threatening to destroy her glasses. The only thing that prevents it from being one is the "Goodie Two-Shoes Pose" requirement.
%%* SuperpowerLottery
* TalkingIsAFreeAction: it may be more of a premise of the whole show than HeartIsAnAwesomePower.
** Early in the series a candidate was dragged into Hell instantly. Later, [[spoiler:Kobasen]] suffers from the same problem, but he retells a five-minute-long flashback in the process.
*** Not to mention that [[spoiler:Inumaru]] does the exact same thing in Dogura Mansion.
** And that part with "safe zones". It's said that if you spend 10 seconds in a safe zone, you instantly lose. A guy stands there while everybody else dumps exposition for more than half a minute.
** Delivering exposition while dodging lasers. Try to beat that.
* TalkToTheFist: In one episode.
-->'''Enemy:''' Do you want to know what my ability is? I'll show you. When I squeeze a stone, I can... *Ueki hits the guy with a tree, knockdown*
* TeensAreMonsters: All of the contestants in the tournament are supposedly junior high school students, yet a lot of them want to be the champion in order to take over the world, and have no qualms about '''''killing their opponents'''''.
* ThatRussianSquatDance: One of the challenges in Dogura Mansion is in the Cossack Field. Participants have to do the dance while wearing cossack hats, in order to breathe on a special low-oxygen environment.
* ThisIsADrill: Robert's Pick is shaped like a drill.
* TooDumbToFool: BJ starts off trying to win fights by claiming to be Robert Haydn, which causes people to run in fear. While Mori falls for this, Ueki just remembers that BJ introduced himself as BJ earlier that day, and just can't seem to understand BJ's claims that his name is really Robert Haydn... And keeps insisting that he's really BJ. The fact that he doesn't even know who Robert Haydn is probably helps.
* TournamentArc: The entire series is one of these.
%%* TrueCompanions
* {{Tsundere}}: Mori, who leans much more toward ''tsuntsun'' than ''deredere''
* TunnelKing: One character has, as he calls it, "A power to turn my beautiful hair into a drill!" which allows him to dig extremely fast.
* UseYourHead: A one-shot character has the power to turn his forehead into diamond when his hands are in his pockets; he then uses his diamond-head to headbutt people into submission.
* WhatKindOfLamePowerIsHeartAnyway: [[spoiler:Subverted. Ueki's power may seem like the weakest, but its Level 2 ability is game-breaking.]]
* WhipItGood: The Namihana, the 8-star Sacred Weapon, is a giant whip.
* YouGottaHaveBlueHair: Ueki and Mori have green and aquamarine hair respectively. Not to mention Rinko, whose hair is pink.
