Power Users
In General
- Brought Down to Normal: Once a power user is defeated in battle, they will be disqualified from the tournament and lose their power.
- Conditional Powers: How powers work in the story. Any given power can only activate given a certain condition inherent to said power. To list a few examples: Ueki's power to turn trash into trees requires the trash to be held in his hands, and Sano has to hold his breath to turn towels into iron.
- Magic A Is Magic A: Every single power in the story works the same way: they transform something into another thing (from physical objects such as towels into iron, to abstractions such as the power to turn ideals into reality). Additionally, all of them come with a certain condition the user has to do to activate it, such as putting their hands inside their pockets or holding their breath.
- Next Tier Power-Up: How Level 2 powers work. They are the logical extension of the user's original power, and can be obtained by mastery of said power.
Team Ueki
Kōsuke Ueki (植木 耕助)
Kosuke Ueki is the main character in the series. He is in Class 1-C at Hinokuni Junior High School. Ueki's ability is given to him by Kobayashi (a.k.a. Mr. K), who is also Ueki's homeroom teacher. His level 2 power is to undo the opponent's power. He can use more than one sacred treasure weapon at the same time because of his given ability.
- The Ace: Before he lost his talents, he was a model student, popular with girls, and one of the track team's most athletic members.
- All-Loving Hero: He spares even Robert on instinct during their fight.
- Anti-Magic: His Level 2 ability reverses the process of any ability.
- Awesome by Analysis: So much that once he's figured out your powers and how they work, it is pretty much an Instant-Win Condition of Ueki; from that point in the fight onwards its only a matter of time before he beats your face in.
- Brilliant, but Lazy: His initial characterization.
- The Chew Toy: Courtesy of Ai.
- Chick Magnet: Before he lost this talent. When he was this, Mori commented that every day, a girl would confess her feelings for him and he'd reject them.
- Cloud Cuckoo Lander: Even the author states that he's unpredictable.
- Crouching Moron, Hidden Badass: The moron part comes into full-throttle once the Robert's Ten arc begins.
- Determinator: Nothing can break his spirit if he's fighting to protect his friends.
- Fearless Fool: Seen as this by his opponents.
- The Fool: Initially Brilliant, but Lazy, but eventually settles on this.
- Green Thumb: His power is to turn trash into trees, on the condition that the trash must be held in his hands to do so. Kobayashi gave Ueki this power to repair a tree he had destroyed to demonstrate his heavenly powers, but the latter walked off on him before he could offer him the chance to switch to a more useful power, being stuck with this since. Its evolved Level 2 power turns out to be a real Game-Breaker as it can negate any ability, based on the laws of recyclingnote .
- Heavy Sleeper: Initially which led to the belief that he was Brilliant, but Lazy.
- Honor Before Reason: He uses his tree power to interfere to fight any injustice that he comes across, despite the fact that using that power on non-contestants makes him lose his talents and eventually disappear when he has no more.
- Idiot Hero: He's usually not too bright, which makes his analysis skills even more amazing.
- Made of Iron: Which causes Robert to undergo a Villainous Breakdown.
- Meaningful Name: His surname "Ueki" (植木) can be literally translated to "planted tree", alluding to his power.
- Mellow Fellow: He is an unusually calm individual.
- Missing Mom: It turns out that she's dead. That's his human adopted mom. Played straight with his real Celestial mom who's implied to have left his real dad after he was dropped off in the real world.
- Multi-Melee Master: Most Celestial Beings can only summon one Sacred Weapon at a time. Ueki's level 2 Celestial power (not his regular level 2 ability) allows him to summon more than one or all of them at once.
- No Sense of Direction: In the fight against Marilyn's team, he couldn't figure out where his teammates were and ended up in other places in that area until he backtracked to where he beat one of his opponents, took the scanner from him and used it to find his friends.
- Power at a Price: Due to awakening his Sacred Weapons late into his age and after gaining his main ability, they are permanently imbued with his tree ability, making them bigger and stronger than regular Sacred Weapons. That being said, the rules of his ability also permanently applies to his Sacred Weapons, thus he can't use them on non-competitors lest he'll lose one Talent per hit.
- Down to his last two Talents, this is why he restrains from using his Sacred Weapons in Plus.
- Power Gives You Wings: His second to last God power.
- Spell My Name With An S: His first name is usually romanized to "Kosuke", although the Animax version spells it as "Kousuke" instead.
- Talk to the Fist: What Kosuke tends to do to his opponents since he doesn't want to listen to them rant.
- Teen Genius: Before he lost his intelligence. He was so smart before he lost his powers that he could take tests and get 100 percent on them while he was asleep!
- This Loser Is You: Justified in that he actually is one of the smarter and athletic characters in the series as well as a Chick Magnet. However, his sense of justice is so high, he uses his powers on thugs often and as a result, loses all the above and becomes this. Mori and everyone around him lampshades this.
- Too Dumb to Fool: B.J. tried to scare him by pretending to be Robert Haydn. However, since B.J. already introduced himself as B.J. to Ueki earlier that day, and Ueki did not know who Robert was at that time, Ueki's reaction was simply confusion, and he kept insisting that his opponent is B.J., not Robert.
- Your Days Are Numbered: He has the fewest talents in the series because he keeps wasting them by doling out justice to jerks and as a rule, whenever he hurts a non-God candidate with his powers, he loses a talent. Once his talents reach zero, he'll die. Mori has to keep reminding him not to use his powers but he doesn't listen.
Ai Mori (森 あい)
Ai Mori is one of Ueki's classmates at Hinokuni Junior High School. She discovers Ueki's power early on, coming to a rather unusual conclusion and at first believing him to be an alien. Upon learning of the competition Ueki is in, she decides to back him up, to keep him from losing all his talents and disappearing because of it.
- Badass Normal: For half of the series before she got her powers, she was able to hold her own in battle by outsmarting many of the villains.
- Characterization Marches On: Her introduction marks her as a bit of a Cloudcuckoolander, as she stalks Ueki on the belief he was an invading alien, but over time she instead becomes the straight woman to his own quirks. She remains a bit of an oddball when hamming up, though.
- Curtains Match the Window: Her hair and eyes are of the same color.
- Damsel in Distress: Subverted. She actually doesn't need to be rescued that often and when she's threatened, she's usually knocked to the side out of danger.
- Fetish: Her power forces the person to have a glasses fetish.
- Fire-Forged Friends: With Ueki, as she starts as a paranoid classmate who distrusts him and ends up becoming True Companions with him and the rest.
- The Generic Girl: Until she gets her powers.
- Goggles Do Nothing: Her glasses are just for reading, so she keeps them in her hair the rest of the time. She also keeps a ton of them with her at any given time.
- He Who Must Not Be Seen: Barely subverted with her parents, who only make a few cameos both in the manga (as they often worry about their daughter) and anime (mainly her father goofing around).
- Jerk with a Heart of Gold: When in a casual mood, Ai is usually upbeat and friendly, although she is often shown with a very shallow side, initially believing that all power-users (with the exception of Ueki) are dangerous enemies that can't be trusted. Still, Ai cares deeply for her friends, especially Ueki.
- Large Ham: Becomes one when angry, which leads Robert to taunt her for it.
- Lethal Chef: Subverted. Her food looks bad but tastes great.
- The Load: A more straight example than Hideyoshi. She has useless powers that can't help her friends out. Becomes more evident in the final battle in which all she can do is stand there and watch Anom kicked the crap out of Sano and Rinko.
- Meaningful Name: "Mori" in kanji means "forest". "Ai" can mean "love". Thus her full name can translate to "loves (the) forest" and since Ueki makes a lot of trees...
- Protectorate: To Kosuke.
- Tsundere: She is typically very abrasive, and only shows her softer side when things become dramatic.
Seiichiro Sano (佐野 清一郎)
Sano can change towels into iron by holding his breath, but due to the limitations of animation, he frequently uses his power without any apparent limitations; this is especially noticeable in battle sequences.
- Alliterative Name: His first and last name both begin with "S".
- Awesome by Analysis: He can figure out a person's power very quickly. On the down side, he's knocked out before he can do anything.
- Break the Cutie: Carpaccio tried this on Sano by threatening to kill his God Candidate Inumaru that he probably saw as more than a friend by planting a bomb on his neck and if he didn't join his team, he would set it off. He then forces Sano to fight against his friends. While Sano was trying to go around the deal by pretending to lose to Kosuke, Capucho wouldn't fall for it and then puts Mori and Rinko's life on the name as well as Inumaru. It's when Inumaru sacrifices himself to give Mori her powers and goes to Hell as a result is when he finally breaks down. Capucho then pushes his buttons by calling his friend a loser for forfeiting his chance to become God for someone like him. And while Kosuke stands up for him and demands to fight Capucho to take back what he said, Capucho declares that Sano won the match because Kosuke finish him off and then forces Sano to watch from the audience stand as he beats up Kosuke quite a bit. At this point, it becomes obvious that this tactic worked but Sano quickly grows out of it.
- Distressed Dude: Subverted. Kosuke assumes he's this when Inumaru claims about Robert capturing Sano but Sano clearly states he joined Robert's crew on his own free will. He still needs to get out of the jam of course.
- Extra-ore-dinary: Can turn towels into steel by holding his breath.
- The Lancer: To Ueki.
- Noodle Incident: How he got the burn on his face. All the character manual says is that he got into an accident at the hot springs.
- Parental Neglect: This is the case for Sano's family since Sano never mentions his parents nor do they get screen time. The way he treats Wanko is more like a father than a friend and then there's the fact that Sano actually doesn't live where the series take place and in the sequel, he seems to be out of the country BY HIMSELF.
- Protectorate: To Kosuke.
- Scars are Forever: The burn on his face.
- Selective Magnetism: His Level 2 ability.
- Ship Tease: He has a few moments with Rinko.
- Weak, but Skilled: He is very creative with his attacks, like making iron springs and boomerangs.
- The Worf Effect: He usually has to lose or get beaten up badly so Kosuke can jump in and finish the battle.
Rinko Jerrard is a 15-year-old power user who can create bombs from beads. She creates special accessories in order to use her beads in more constructive ways.
- Beware the Nice Ones: Overlaps with being Cute and Psycho in Sano's eyes.
- But Not Too Foreign: If her last name isn't a big hint.
- Cute and Psycho: Sano thinks she's this.
- Cuteness Overload: This is her major weakness. When she sees something cute, she can't attack it. However, if you set her off, then it doesn't matter if the thing is cute. She will beat you up.
- High-Heel–Face Turn: She wasn't evil but she was planning to finish Kosuke off until he won her over to his side.
- Important Hair Cut
- Lonely Rich Kid: Before she met Robert.
- Love Martyr: Was wholeheartedly devoted to Robert's goals before joining Ueki.
- More Dakka: Her Finger Bead Cannons.
- The Ojou: Comes from a rich family, but it caused her to be ostracized by her peers.
- Rocket Jump: By embedding beads inside the soles of her sandals.
- Ship Tease: With Sano.
- Stuff Blowing Up: Can turn beads into bombs.
- The Smart Girl: All the weapons she uses in conjunction with her powers? She made them herself!
Hideyoshi Sōya has the ability to turn voices into portraits and can make voices come out of them. The condition is that he needs to bend his fingers or toes.
- Animal Stereotypes: He is commonly referred to a monkey by his friends and enemies. He even acts like a monkey and looks like one. His own Chosen profile pic is of a gorilla.
- Art Imitates Life: Can turn voices into portraits.
- Confusion Fu: His favored tactic in conjunction with his ability to turn voices into portraits.
- Expy: Of Jack from MÄR.
- The Load: Hideyoshi knows he's this and prays that he never has to fight in the tournament. Luck is usually on his side.
- Loud of War: His ability is to turn voices into portraits, which then plays back the sound. He often uses this as an attempt of Confusion Fu.
- Named After Somebody Famous: Sengoku era general Toyotomi Hideyoshi, one of the three unifiers of Japan. It could be coincidence, if not for the fact that Sōya looks like, acts like and is called a monkey. Toyotomi Hideyoshi was famously called Monkey by Oda Nobunaga for his looks.
- Promotion to Parent: Or at least an older brother figure to the orphans.
- Screw This, I'm Outta Here: During the last battle, he abandons his friends because he knows he can't beat Anon. He comes back near the end because he realized he wouldn't be able to forgive himself if his friends died. This causes him to get knocked out by one of Kosuke's attacks, saving his life by giving him one more talent before taking down Anon.
- The Trickster: In his introduction, he tricks Ueki and Mori into doing his car wash job. And that's only the tip of the iceberg.
- Ventriloquism: His ability is to turn voices into portraits. By undoing the power, the portraits turn back into voices, allowing him to make his voice come from different locations. He's especially good at using it to surprise, distract, or misdirect his opponents.
- Weak, but Skilled: Though his power is next to worthless, he is good at using it to distract and confuse his enemies.
Minor Characters
Maruo Taira (平 丸男)
- Explaining Your Power to the Enemy: Not only does he explain how his powers work, but he also explains how he learned to improve the practical use of his powers, inspiring Ueki to do the same with his.
- Playing with Fire: His power is to turn water into fire by putting it in his mouth. His firepower gets stronger if he gargles the water, and he can even use it to create fireballs.
Hayao Adachi (足立 駿夫)
- Flechette Storm: Downplayed. His power is to turn cotton into metal stakes, which he then throws at his foes. Unlike most examples, however, Adachi usually throws one or two stakes at a time, and will only throw multiple stakes at once to block opponents rather than to injure them.
- Green-Eyed Monster: His fight against Ueki, apart from the fact that they are both power users, becomes personal because he is jealous towards Ueki's talent at running.
Li Hō (李崩)
- Charles Atlas Superpower: His martial arts training somehow allows him to do feats that no human in real life would be able to do, such as splitting a large metal pole in two, breaking giant boulders with his head, and repeatedly turning Ueki's tree attacks into sawdust without so much as breaking a sweat.
- Disappeared Dad: Li Ho's father, a famous martial artist, died from a disease when he was young. The loss inspired Li Ho to pursue martial arts as well, so that he can be as strong as his father and continue his legacy.
- Fights Like a Normal: Although he is a power user, he is never seen using his power in the story, preferring to use his martial arts skills to fight instead.
- Informed Ability: According to his God-candidate sponsor Ganji, his power (that he is never shown using) is to turn strands of his hair into a Telescoping Staff. The condition of his power is not known.
- Shout-Out: His special martial arts technique to break through boulders is called 岩窟王 Gankutsu'ou in Japanese. Although it can be literally translated to "King of the Cavern", it is also part of the Japanese title for the novel The Count of Monte Cristo; thus, the English name for his technique is called "The Count of Monte Cristo".
- Signature Headgear: He always wears a round hat with a cross on the front. Ueki even lampshades how cool the hat looks, and says that he wants to have the same hat for himself.
Junichi Baba (馬場 淳一) / "B.J."
- Affectionate Nickname: B.J. calls Ueki his "bro" (or "brother" in Japanese) due to their shared love for hip hop. Ueki returns the favor.
- Blow You Away: His power turns coins into whirlwinds.
- Compulsive Liar: B.J. constantly lies about his age, and during battle, he lies and tells his opponents that he's Robert Haydn, the strongest power user. Also, ever since he was a child, he would often tell tall tales to impress his peers and gain friends; unfortunately, he's often found out, causing him to lose friends anyway. His fight with Ueki, who was the only one not fooled by his "Robert Haydn" bluff, causes him to start changing his ways.
- Confronting Your Imposter: On the receiving end of it. After repeatedly fooling everyone as "Robert Haydn", he ends up suffering defeat and serious injury at the hands of the real deal.
- Dreadlock Warrior: He styles his hair in dreads, and he's a quite formidable power user.
- In-Series Nickname: He's often referred to as "B.J.".
Robert's Ten
Robert Haydn (ロベルト・ハイドン)
- All of the Other Reindeer: He was always shunned by the citizens of his childhood town.
- Anti-Villain: Robert demonstrates a sense of honor and fairness on many occasions, such as when he manages to fit bracelets laced with a deadly poison onto the entire main cast, then proceeds to let them walk free when they win his little underworld game.
- Cassandra Truth: He told the truth, that he didn’t make or threaten his friends to stealing food. But sadly, none of the towns people listened or believed him.
- Cast from Lifespan: His ability to make ideals real cuts off a year of his life per ideal used. The primary function of Robert's Ten is to do all the fighting for him so he doesn't have to use the remaining years of his life to fight.
- Creepy Child: His perpetual smiley-face is simply unsettling.
- Creepy Monotone: Which complement his looks. He only raises his voice when being extremely pissed.
- Dark and Troubled Past/Freudian Excuse: His childhood was full of abuse from both his peers and the adults, due to his Celestial powers being awakened early.
- Disc-One Final Boss: Spends the first half of the series as the Big Bad but after his second battle with Ueki, he begins to have doubts over his plan. Seeing this a threat to their plan, Anon eats him and takes over his place in the tournament.
- Fur and Loathing: Wears a parka in his introductory arc, and is one of the most dangerous power-users in the tournament.
- Gravity Master: His Level 2 ability, usually manifested in the form of bubbles.
- Heel–Face Door-Slam: He was considering joining up with Kosuke and the group because they showed him the wonders of The Power of Friendship. Then his God candidate appears with Anom and Anom easily defeats and swallows. Thankfully, he's saved by Kosuke by the last episode and does a complete Heel–Face Turn.
- Start of Darkness: After being betrayed by his friends and when the director (the man in charge of the orphanage) said he didn’t like him and only took care of him, for money. All this combined, caused Robert to snap and destroyed the town where he lived.
- Teens Are Monsters: Like the majority of the villains in the series.
- Where I Was Born and Razed: After his Break the Cutie moment, he finally snapped and destroyed his home village along with the citizens.
- Your Mind Makes It Real: His ability is to make an ideal real at the cost of a year of his life per ideal.
The second-in-command of Robert's Ten.
- The Dragon: To Robert.
- Edible Theme Naming: Carpaccio is named after an Italian dish with the same name, consisting of thinly sliced raw meat.
- Hawaiian-Shirted Tourist: Dresses like one, complete with shorts and sandals.
- Hoist by His Own Petard: This is how Ueki defeated him with Tenko's help.
- Mind Reading: Literally; one of his copied abilities outside of Robert's Ten is to turn his enemies' thoughts into phone mails, which he can read and use to his advantage.
- Power Copying: His main ability enables him to copy the abilities of all the other contestants, provided he stays within 10 meters near them for at least 24 hours. Using his position as the second-in-command of Robert's Ten, he's able to copy all the powers of the other members in the group, plus an additional two more he gained outside of the Ten.
- Sue Donym: Carl P. Accio, nicknamed "Carpaccio".
- Teleport Spam: The other ability he obtained outside of Robert's Ten is the ability to switch places with his opponents.
Kageo Kuroki (黒木 影男)
- Dishing Out Dirt: His ability is to turn his shadow into clay golems.
- Doppelgänger Attack: His preferred tactic is to turn his shadow into multiple copies of himself, attacking Ueki all at once.
- Foil: To Kamui Rosso, who shares a similar ability and nickname. Kageo can make multiple clay figures with his shadow, whereas Kamui can only make one robot at a time. Despite joining the ranks of Robert's Ten, Kageo still has a nicer side, and is moved by Ueki when he stops fighting him because the sky is overcast — Kageo gets dispatched by Kamui immediately after, who feels nothing for such sentiments.
- Face–Heel Turn: He realized that life is not fair after his basketball team was disqualified for the Nationals for taking revenge against their last opponent who dealt a No-Holds-Barred Beatdown on their ace player.
- Giant Mook: He can also make a humongous Clay Golem out of his shadow, but he uses it to finish off his opponents.
- Meaningful Name: His name contains the words for "black" (黒 kuro) and shadow (影 kage), alluding to his ability.
- Red Baron: Has the moniker "Black Shadow" (黒影 Kurokage).
- Foil: To Kageo Kuroki, who shares a similar ability and nickname. Kamui can only make one robot at a time, in contrast to Kageo's ability to create multiple clay golems — however, Kamui's steel robot is a lot stronger in attack and defense than Kageo's clay men. Kamui is also noticeably crueler than Kageo, having no qualms eliminating his own teammate as soon as he sees him being no longer fit for purpose.
- Red Baron: Has the moniker "White Shadow" (白影 Shirokage).
- Robot Master: His ability is to turn his shadows into Mecha-Mooks.
- You Have Outlived Your Usefulness: Becomes his Establishing Character Moment, even; his first appearance sees him knocking Kageo out cold using his robot, after figuring out that the latter is unable to defeat Ueki.

- Shear Menace: His ability allows him to turn his bamboo sword into giant hedge clippers.

- Precision-Guided Boomerang: His other ability is to turn CDs into buzzsaws.
- Verbal Tic: Ends his sentences with "~su". It was changed to "like" in the English dub and "ya know?" in the Spanish one.
- Abnormal Ammo: He uses pachinko balls to shoot his opponents without using his ability.
- Cape Wings: His main ability is to turn his cape into a pair of wings.
- Feather Flechettes: His Level 2 ability allows him to turn the feathers on his wings into sharp blades.
- Affably Evil: Very little about him even suggests he's evil in the first place. He only attacks Ueki when he tried to stop him from eating.
- Confusion Fu: Strike weird poses while using his power to hide the actual limiting conditions.
- Food-Based Superpowers: Yunpao has the ability to transform electricity into sugar and back again.
- Shock and Awe: He can turn electricity into sugar, which is sprinkled all over his opponents. The Shock and Awe comes in when he reverts the sugar back to electricity.
Capucho Team
- An Ice Person: He can turn his voice into freezing gas.
- Breath Weapon: More like Voice Weapon, but still counts.
- Hoist by His Own Petard: He's defeated by his own voice that got turned into portrait (that still shoots freezing gas) by Hideyoshi.

- Hollywood Acid: His ability is to turn stress balls into this.
Grano Team
- Art Initiates Life: Can turn models into working replicas.
- Hoist by His Own Petard: TWICE!. Brings a model of Ueki to life and then orders it to attack the evil before it. Being an exact copy of Ueki, the clone helps the real one beat him up!
- Too Dumb to Live: Really, what did you think an exact copy of Ueki would do?
- Token Good Teammate: The only one in Grano's team who is not fond of fighting Ueki's team.
- What Kind of Lame Power Is Heart, Anyway?: His power basically enables him to turn photos into toy models. Without Grano's power, Pecol would be very useless in a fight.

- Power Misidentification: Initially claims his powers are invincibility and the power to turn his voice into a shockwave.
- Verbal Tic: "Baby".
- Incredibly Lame Pun: His ability is to turn this trope into reality, but the opponent has to laugh at his puns first in order for it to work. This is why Pastello's power works very well with his.

- Super-Strength: Her level 2 ability doubles her attack power for 10 minutes, after which she passes out.

Kobayashi (小林)
- Actual Pacifist: Though he will act occasionally in defense of his students.
- Not the Fall That Kills You…: Pulls this three times on Ueki. And while he tends to complain that the catch hurt his arms, neither of them are actually ever injured from it.

- Better to Die than Be Killed: After Carpaccio reveals that he placed a remote-control parasite that will suck Inumaru's blood dry if Sano, his candidate, didn't join Carpaccio's team, Inumaru gives Ai a power, thereby making him go to Hell (since god candidates are not allowed to give powers to two people), where the bug can't be activated from there.
- Butt-Monkey: Word of God actually confirmed that pretty much his main purpose in life is to be picked on by Kobayashi.
- Expy: He looks like a saner and more level-headed but wimpier version of Urahara Kisuke.
- In-Series Nickname: He
- King of All Cosmos: And your new god is a Butt-Monkey!
- Reasonable Authority Figure: Quite possibly the only sane adult in the series.
- Scarf of Asskicking: Wears a black-and-white scarf with a "19" tag on it.
- Throw the Dog a Bone: He's a huge Butt-Monkey... And then the kids pick him as King's replacement.
- Wingding Eyes: He doesn't have pupils, just spirals in his irises. (Then again, he's not exactly human, either.)

- Grand Theft Me: A victim of this by Anon's father before the series started.
- Gender-Blender Name: Margaret is a woman's name, but he's a man.
