* AthleticallyChallenged: Due to relying one his psychic powers, he is very physically weak. He joined the Body Improvement Club to overcome this.



* AxCrazy: Mob [[note]] only [[/note]]appears to be fairly stoic under normal circumstances. When he does go off emotionally, he [[AllLovingHero is often surprisingly conscientious of people around him]], reserving the force of his explosions for whomever actually set them off.

* {{Bishounen}}: While he is usually considered plain-looking, his [[{{Determinator}} 100% Courage]] form enhances his better traits and makes him look like one.



* CoolLoser: He's initially defined by his lackluster attributes in everything that isn't related to spirits and psychic power, but he eventually gains a good number of friends in the forms of both the Telepathy and Body Improvement Clubs, respect from the delinquent gang at Salt Mid as their Urabanchou "White T Poison," and starts to gradually grow out of the "loser" part of the trope as he gains more confidence in himself.

* CoolLoser: He's initially defined by his lackluster attributes in everything ComicallyMissingThePoint: During the Psycho Helmet Cult arc, he mistakens the fact he spoke to four girls within hours on a school day as a sign that isn't related to spirits he became popular with girls. It gets even worse when other girls swoon his way (but not towards him, but rather real [[ChickMagnet chick magnets]] like Ritsu and psychic power, but he eventually gains a good number of friends in the forms of both the Telepathy and Body Improvement Clubs, respect from the delinquent gang at Salt Mid as their Urabanchou "White T Poison," and starts to gradually grow out of the "loser" part of the trope as he gains more confidence in himself.Teru).



* ForgettableCharacter: Mob lacks presence so much that the few rumors he does provoke instead attach themselves to his younger brother. His schoolmates--including those in the ''Telepathy'' Club--can barely even remember he has psychic powers even though he's never actually made a secret of them.
* TheFettered: Thanks to some choice words Reigen gave him when he was younger, he's been able to hold back on his psychic abilities responsibly and reasonably maturely. It comes around to seeing his powers as "knives" -- he shouldn't be pointing them at anybody for no good reason. This also extends to his emotional repression, as if he ever truly lets go or has no limiter, he can become dangerous to everyone around him.

* MeaningfulName: His nickname, "Mob" (モブ), is derived from "Mob Character," i.e. a background character or NPC. Shigeo begins the story with little sense of presence, suppressing his emotions and trying to live like a common person despite everyone trying to take advantage of him. It also doubles as an AlternateCharacterReading, as his given name can be read as "Mobu".

His nickname, "Mob" (モブ), is derived from "Mob Character," i.e. the Japanese term for a background character or NPC. Shigeo has a rather plain appearance befitting of such a character and begins the story with little sense of presence, suppressing his emotions and trying to live like a common person despite everyone trying to take advantage of him. It also doubles as an AlternateCharacterReading, as his given name can be read as "Mobu".



* MistakenForBadass: Played with. Mob is by far the most powerful character in the story for his tremendous esper abilities, but otherwise he looks like a weak little boy, incapable of any physical might; thus when Mob gets tangled with delinquent feuds, and minor foes who don’t quite get his psychic powers, they think Mob is some secret badass who’s just hiding his true physical strength after he either defeats them or have his shredded friends from the Body Improvement Club help him out; for that Mob is nicknamed "Uraban" (Ura Banchou / Secret Boss Delinquent) among school thugs, for they see him as the unassuming secret boss of his school.

* NoSenseOfHumor: Not for a lack of trying. Not even intentionally letting Dimple's laugh-inducing mind control through his barrier had any effect on him. [[spoiler:He finally laughs in Chapter 101 after accidentally sending Reigen's birthday cake flying into his face with his powers.]]
** Downplayed: During the Mogami arc, he cracks a joke--his first in the series--with Dimple, marking a milestone in his emotional growth.

* PowerLimiter: More metaphorical than most examples: subconsciously [[EmotionSuppression suppressing his emotions]] keeps his powers in check, as does his kindness and Reigen's advice not to use his powers on other people. Building up an emotional charge that exceeds his ability to hold it back trips the limiter.

Added DiffLines:

* SoullessBedroom: Compared to that of his brother Ritsu--whose room screams 'generic middle-class gifted kid'--Shigeo's ample bedroom is empty. Empty, except for a desk and chair, a small bookcase, a closet, a dresser, and a neatly folded and enviably plush futon. It's also unnaturally tidy for a teenager's room.
** Downplayed: Upon closer examination, his bookcase contains his favorite manga, study books for subjects he struggles with, and books that hint at his desire to learn more about people in his life. His bedroom doesn't change to reflect his emotional and spiritual growth over the course of the story either, unlike many examples of this trope. Shigeo just seems to prefer living in near-ascetic simplicity.

!Shigeo "Mob" Kageyama
!!!'''Voiced by:''' Setsuo Itou (Japanese), Creator/KyleMcCarley (English), Carlos Siller (Latin American Spanish), Ítalo Luiz (Brazilian Portuguese)
!!!'''Portrayed by''': [[Series/UltramanGEED Tatsuomi Hamada]]
[[quoteright:125:https://static.tvtropes.org/pmwiki/pub/images/mob_anime.png[[labelnote:100% Explosion]]https://static.tvtropes.org/pmwiki/pub/images/100percent.png[[/labelnote]]]]

->''"I don't really get it."''

Shigeo "Mob" Kageyama (影山茂夫; ''Kageyama Shigeo'') is a middle schooler with psychic powers linked to his emotions. Being stressed enough can charge Shigeo's abilities to world-shattering lengths, so he studies under Reigen and tries his best to avoid misusing his powers. Often socially awkward and sporting an expressionless face, he is more concerned about making friends and realizing his purpose in life than fighting dangerous espers or being the leader of a cult.

[[folder:]]
* AchievementsInIgnorance: His defeat of the Kuchisake-Onna (or Dragger in the anime). Since the being was created by urban legend and sustained through the fear of those who believe in it, people well acquainted with the myth (such as Shinra and Reigen) were unable to exorcise it properly. Mob, having been socially isolated for many years, had no such fear in his heart and was able to destroy it cleanly.
* AfraidOfTheirOwnStrength: After his first ???% explosion, Mob stopped viewing his powers as a neat trick that lost their novelty and started seeing them as outright monstrous.
* AlternateCharacterReading: The characters in his given name, Shigeo, can also be read as "Mobu", hence his nickname.
* AnimeHair: His hair is normally an ordinary-looking bowl cut, but it becomes wild and spiky at 100% power. Justified in that it seems to be his own power aura lifting his hair.
* AngelFaceDemonFace: 100% Mob tends to look [[https://i.imgur.com/3OxZJnv.png a lot cuter and less deranged]] when set off by more positive, productive emotions. Dimple's so thrown off by the difference that he can't even recognize Mob during the first "good" explosion he witnesses.
* AngstNuke: Thanks to his volatile powers, his emotional explosions are often very literal.
* ApologeticAttacker: While he does grow out of his SuicidalPacifism, he never feels good about using his power on people and often apologizes for resorting to force... Unless you hurt Ritsu, in which case you [[BigBrotherInstinct brought it down on yourself]].
* AstralProjection: Does this to combat Mogami.
* AttractiveBentGender: Ironically, the only time in the series he actually did get popular with girls was [[EvenTheGirlsWantHer when he was disguised as one]].
* AxCrazy: Mob [[note]] only [[/note]]appears to be fairly stoic under normal circumstances. When he does go off emotionally, he [[AllLovingHero is often surprisingly conscientious of people around him]], reserving the force of his explosions for whomever actually set them off. There are ''exceptions''. Some notable ones:
** Expect indiscriminate destruction whenever [[SuperpoweredEvilSide ???%]] is in play, as Mob is no longer holding the reins.
** 100% Obsession / Tenacity, after Dimple talks him down from starting WWIII on accident [[spoiler: when he sees what look like the crispy corpses of his family in his burning home]]. Mob's normal concern for others' safety is gone as he picks a vicious fight--in the middle of a crowd--with two grown men. He then nearly sends [[ThoseTwoGuys Koyama and Sakurai]] through the windshield of their car when they try to calm him down.
** 100% Ecstasy and 100% Resignation, in which he faces an equal for the first time [[spoiler: in battle against Suzuki]]. We get a good sense of how cold-hearted and maniacal this teenager can be if [[TheUnfettered he sheds his inhibitions completely]]. [[spoiler: That laugh on his lips as he absorbs Suzuki's BeamSpam in the beginning of their battle is deeply unsettling; as is his contorting the man's body beyond belief in order to force an end to their fight.]]
* TheBabyOfTheBunch: The Body Improvement Club can be very protective of their littlest member.
* BadassAdorable: Mob's a cute walking bowl, but he's also disturbingly powerful.
* BeadyEyedLoser: His irises are drawn much smaller and duller than his younger brother's to mark him as the plain, awkward one of the two. He usually loses this during his [[SuperMode 100% explosions]], instead sporting sharp, red TsurimeEyes.
* BewareTheNiceOnes: He's about as humble and gentle as anyone can hope to be right up until he hits the end of his CatastrophicCountdown.
* BigBrotherInstinct: Seriously, don't hurt Ritsu in his presence. [[spoiler:Seeing Ritsu get beat up by a member of Claw caused Mob to openly show rage, before his counter reached full capacity; not to mention that scene marks the fastest his counter had gone up.]]
* BigGood: The strongest force for good in the series so far, as his influence has made many other characters kinder and more humble. [[spoiler: After their fight in the Divine Tree, Dimple flat out tells Mob that the strength of his powers, combined with his careful and earnest personality, could make Mob a true leader and unifying force for the people of Spice City, compared to Dimple's plays at godhood through brainwashing.]]
* {{Bishounen}}: While he is usually considered plain looking, his [[{{Determinator}} 100% Courage]] form enhances his better traits and makes him look like one.
* BookDumb: Mob is a bit annoyed that none of that unfathomable psychic talent he was born with seems to have any positive impact on his GPA.
* BoxingLessonsForSuperman: Since he was unable to impress the girl he likes with his powers, he believes they are not necessary in daily life. So he enters the Body Improvement Club to become stronger without depending on them.
* BrokenAce: He can effortlessly wipe extremely powerful psychics off the face of the earth, but he doesn't really enjoy any of that power, and would happily trade it for his brother's social and academic skill. He constantly represses his emotions out of fear of causing a catastrophe, and may be suffering from depression.
* BrutalHonesty: While kind and soft-spoken, he also voices his opinions very bluntly and doesn't try to spare feelings if he has a bone to pick.
-->'''Reigen:''' So, that rules out any natural causes. What do you think, Mob?
-->'''Mob:''' I think you should stop asking me to drop everything for you.
* CatastrophicCountdown: When Mob experiences spikes in his emotions, building up towards his bursts of power. Though, depending on the emotion he feels at the moment, it's not always catastrophic.
* CharacterDevelopment: Gradually becomes more confident, sociable and less dependent on Reigen. This has a lot to do with his training in the Body Improvement Club, where he goes from almost the very bottom to the upper half in his second year. That, and a lot of good teaching from Reigen.
* {{Chuunibyou}}: Inverted; he legitimately has incredible strong PsychicPowers, but he doesn't see them as a big deal, both because of his desire to improve in more mundane areas of life (like physical fitness and social interactions) and because he's internalized the philosophy that having powers doesn't automatically make him better or more special than everyone else.
* ClassicalAntiHero: Self-doubting, emotionally fragile, and hates having to fight and hurt people, despite the world's best attempts to drag him into fighting evil.
* CoolLoser: He's initially defined by his lackluster attributes in everything that isn't related to spirits and psychic power, but he eventually gains a good number of friends in the forms of both the Telepathy and Body Improvement Clubs, respect from the delinquent gang at Salt Mid as their Urabanchou "White T Poison," and starts to gradually grow out of the "loser" part of the trope as he gains more confidence in himself.
* CreepyChild: While he is one of the nicest kids you'll ever meet, when his power lashes out, he turns into a horrifying force of nature in the body of a child. It doesn't help that even when he is genuinely enraged, he doesn't entirely lose his quiet and polite demeanor, which leads to cold and hate-filled TranquilFury far more eerie and disquieting than any screaming fit of rage would be.
-->''(to Koyama, in the middle of a NoHoldsBarredBeatdown):'' Hey, mister [[BigBrotherInstinct who did terrible things to us...]] just so you know, this is all your fault.
* CrouchingMoronHiddenBadass: {{Downplayed}}. Mob is by no means a moron, but he isn't an excellent student and can be quite naive and unskilled when it comes to social situations despite being quite mature for his age. However, he has very strong psychic abilities that can curb-stomp most people in a fight.
* CurbStompBattle: If he has enough power stored and isn't holding back, he can bring down anyone in a few moves. [[spoiler:The only reason why he wasn't able to defeat Koyama at first was because he was holding back, and because Koyama had knock-out spray. When they meet again, he doesn't hold back and easily hands Koyama an instant ass-kicking]]. Averted with later opponents, who seriously put up a fight and even force [[spoiler:Mob to use several 100% modes to keep up.]]
* DelicateAndSickly: He has chronic anemia and often passes out during club activities as a result. It also serves as a DramaPreservingHandicap, as it makes him highly prone to {{Power Strain Blackout}}s alongside his mundane fainting spells.
* {{Determinator}}: Mob gets rather dangerous at 100% emotion. Before that, he's taken quite a few beatdowns, but still refused to give up.
* DidNotGetTheGirl: [[spoiler:The ??? arc ends with Mob finally confessing his feelings to Tsubomi, and being soundly rejected by her in response. They manage to stay friends though.]]
* DoesNotLikeSpam: His least favorite foods are cilantro, shiokara, and locusts.
* DullSurprise: Unless he's at 100%, his facial expressions tend towards this. He's also stated to have limited emotions in everyday life.
* EmotionalPowers: The more stressed Mob becomes, the closer his explosion counter gets towards 100%. Strong enough emotions can drive it ''far'' beyond that, to the point that unlike his unconscious "???%" mode, his power isn't even ''knowably'' unknowable, with the percentage simply expressed as a smudge.
* EmotionBomb: He's capable of projecting his memories, feelings, and perspective into others. However, he doesn't use this as a weapon, but rather as way to communicate his feelings as clearly as possible, since he's not great at expressing himself in the usual ways.
* EmotionlessBoy: Has grown used to being like this as a way to suppress his powers.
* EmotionSuppression: The original cause of how he came to be as deadpan and emotionally flat as he is, shackling his feelings after Ritsu got caught in the blast zone of a ???% emergence.
* TheEmpath: He's able to feel the emotional content of the spiritual energy he absorbs (which opponents are often freely throwing at him during their assaults). Of course, since his ''regular'' social and mood-reading skills are rather subpar, this often leads to him [[InnocentlyInsensitive cluelessly commenting on their deepest insecurities mid battle]].
* EnergyAbsorption: Drains energy from Teru during his ???% state at Black Vinegar Middle School. [[spoiler:By the time he faces off against Toichirou of Claw, he seems to have gained a better grasp on this power even at an emotional state below 100%.]]
* EverybodyHatesMath: While most of his grades are middling, he's absolutely abysmal at math.
* EveryonesBabyBrother: The Body Improvement Club absolutely refuses to use their strength for violence... Unless it's for Mob, as Onigawara is happy to weaponize against Black Vinegar Middle School.
* ExpressiveHair: As he gets less prone to stuffing down his feelings, it becomes increasingly common for his hair to puff up or fray in anger well before he hits 100%.
* ExtremeDoormat: He starts off as one, so unused to making his own decisions that Tokugawa asking, "Don't you have ''anything'' you want to do?" [[ArmorPiercingQuestion gives him an existential crisis.]]
* ForgettableCharacter: Mob lacks presence so much that the few rumors he does provoke instead attach themselves to his younger brother. His schoolmates--including those in the ''Telepathy'' club--can barely even remember he has psychic powers even though he's never actually made a secret of them.
* TheFettered: Thanks to some choice words Reigen gave him when he was younger, he's been able to hold back on his psychic abilities responsibly and reasonably maturely. It comes around to seeing his powers as "knives" -- he shouldn't be pointing them at anybody for no good reason. This also extends to his emotional repression, as if he ever truly lets go or has no limiter, he can become dangerous to everyone around him.
* FullContactMagic: A good sign Mob is losing control of himself is when he stops letting the PowersDoTheFighting and gets up close and physical.
* AGodIAmNot: Reigen instilled in him the philosophy that being an esper doesn't make him better than other people, and as a result Mob tends to deflect all praise that could be put towards his psychic powers. For the most part, the world respects his wishes, with the Telepathy and Body Improvement Clubs supporting his desires to increase his physical abilities, and Ichi recognizing that she probably shouldn't reveal his existence to the Psycho Helmet Cult that began worshiping him after he defeated Dimple.
* GreenThumb: Learns to control plant life when facing off against the Wiggly Figure. [[spoiler:After facing off against the leader of Claw, this power ultimately results in the creation of the Divine Tree, a ginormous head of Broccoli that grows in the middle of Seasoning City.]]
* TheHeart: Since Reigen or Teru are usually more suited to leading, Mob tends to be this until he needs to step up to the plate, with his kindness and innocence keeping everyone else on the straight and narrow.
* TheHero: While Reigen often takes a leadership role due to being... ''relatively'' more mature, Mob himself is pretty much always at the forefront of the action, even when he'd really rather not be.
* HeroicNeutral: He's not interested in any shounen battle or adventure shenanigans, repeatedly dismissing the CallToAdventure because he'd rather work at keeping his PsychoactivePowers from running wild and getting his childhood crush to notice him. [[spoiler:Knowing this, Shou fakes his family's death and burns his house down to force his hand in the World Domination Arc.]]
* HeroicWillpower: Manages to resist [[spoiler:Mogami's attempts at corrupting him]] for what he perceives as ''half a year''.
* HumanoidAbomination: Under the effects of ???% mode, Mob effectively becomes this with the full release of his raw psychic power. [[spoiler:This idea is even further cemented with the fact that ???% has a separate consciousness of its own that seems to be dedicated to Mob's well-being and happiness, since its appearances have been either protecting Mob after being knocked out or, as in Chapter 100, picking up Mob's bouquet of flowers and ensuring that he makes it to his meeting with Tsubomi, life-threatening injury be damned.]]
* IAmAMonster: It's hard to not hate yourself when your one talent is being a part-time HumanoidAbomination.
* IJustWantToBeNormal: Played with. Unlike most characters of this type, he does not necessarily resent his powers per se (at least not usually), and will openly use them to exorcise evil spirits and take down those who seek to harm innocents. However, he does not exactly embrace them either, not really seeing the big deal in being a psychic, since it doesn't really help him improve his personal life. Above all, he doesn't want to have his powers be his sole defining feature, and wants to become good at normal everyday life things, which he perceives as being more valuable than overwhelming psychic abilities.
* IJustWantToHaveFriends: Aside from wanting to be [[IJustWantToBeNormal normal]], Mob's biggest goal in life is to be able to connect with other people.
* InstantExpert: Able to learn plant control and astral projection with little difficulty.
* IWantToBeARealMan: It's a running that gag that Mob's ideas of how to be attractive to girls are a bit... ''[[TestosteronePoisoning off]]'' and that he [[ImagineSpot often fantasizes]] of one day looking like a terrifyingly huge musclebeast like Musashi even though girls at his school are far more interested in boys like Ritsu. Dimple is a bit concerned.
* KidHero: A 14-year-old boy, and one of the world's most powerful espers.
* KubrickStare: Mob's default expression. Becomes a DeathGlare when he actually means it.
* {{Leitmotif}}: When he [[LetsGetDangerous lets loose in battle]], it's commonly accompanied by an eerie tune known as "[[https://www.youtube.com/watch?v=hDJ7P3Td-yQ Explosion of Mob's Feelings]]", which makes prominent use of seamoons, a peculiar instrument best described as an UncannyValley distorted version of human vocalizations (or, more humorously, "'''[[NightmareRetardant threatening kazoos]]'''", according to the Youtube comment section). The dark, surreal sound of the track emphasizes Mob's nature as [[InvincibleHero possibly the single most powerful esper in the world]], and reminds us that despite his harmless appearance and kind nature, an [[BewareTheNiceOnes angry Mob]] is a [[CreepyChild terrifying sight to behold]]. It has a few variations, such as [[https://www.youtube.com/watch?v=N-2eoKZkoks the slower, even more sinister version]] used as the theme of [[SuperpoweredEvilSide ???%]], or the [[https://www.youtube.com/watch?v=vM1Y0sppaCU more badass, heart-pumping version]] used when Mob finally has the chance to [[TheGlovesComeOff let loose with the full extent of his power]] against an equal in [[SuperSupremacist Toichirou Suzuki]].
* LoserProtagonist: Begins as an insecure, all-but-friendless [[TheDitherer ditherer]] with no remarkable talents beyond his psychic powers (which he doesn't find useful in most contexts anyways). He moves out of this after he starts gaining confidence in himself and begins more openly expressing his emotions, gaining a growing circle of close friends.
* MagneticHero: Despite his lack of social skills, he's managed to collect a large amount of friends and allies through his earnestness and kindness, from schoolmates like the Telepathy Club, Body Improvement Club, and Salt Mid's delinquent gang; to former enemies like Dimple, Teru, and the 7th Branch Scar Members of Claw. [[spoiler:It's even noted that this quality may have helped the Body Improvement Club recruit more members after Mob becomes their Assistant Director, especially since the new recruits aren't already muscular like the Body Improvement Club was when Mob first joined.]]
* MartialPacifist: Hates fighting other humans, and will avoid it when at all possible, but push him too far or exhaust his other options, and he will show just how powerful of an esper he is.
* MeaningfulName: His nickname, "Mob" (モブ), is derived from "Mob Character," i.e. a background character or NPC. Shigeo begins the story with little sense of presence, suppressing his emotions and trying to live like a common person despite everyone trying to take advantage of him. It also doubles as an AlternateCharacterReading, as his given name can be read as "Mobu".
** His surname can also be seen as meaningful. "Kageyama" literally translates to "shadow mountain," which could be a reference to how his psychic "shadow" in the spiritual world is like a mountain's compared to other espers'.
** The first character in Mob's given name, 茂, means 'to grow lushly' or 'to be in full leaf'. He awakens [[GreenThumb chlorokinetic powers]] in the show's second season.
* MistakenForBadass: Played with, Mob is by far the most powerful character in the story for his tremendous esper abilities, but otherwise he looks like a weak little boy, incapable of any physical might; thus when Mob gets tangled with delinquent feuds, and minor foes who don’t quite get his psychic powers, they think Mob is some secret badass who’s just hiding his true physical strength after he either defeats them or have his shredded friends from the Body Improvement Club help him out; for that Mob is nicknamed "Uraban" (Ura Banchou / Secret Boss Delinquent) among school thugs, for they see him as the unassuming secret boss of his school.
* MuscleAngst: Muscle is his go-to example for things he'd like to have rather than psychic powers, and he joins the Body Improvement Club under the rather naive belief that [[WomenPreferStrongMen it might get Tsubomi interested in him]].
* MusclesAreMeaningful: Rather than over-rely on his psychic power, Mob does his best to work out his body with the Body Improvement Club. In his second-year marathon, he manages to place in the top half of 180 students, and that's ''with'' an injured leg. [[spoiler:By the end of the Manga, he's gotten strong enough to climb a telephone pole without the use of his powers... though getting down from it with just his muscles is another story.]]
* MutualEnvy: He wishes he were [[IJustWantToBeNormal more normal]] like his brother Ritsu, unaware that Ritsu is secretly resentful and envious of him for having psychic abilities.
* MyGodWhatHaveIDone:
** Mob and Ritsu were once mugged by high-schoolers who knocked him unconscious by pushing him into a wall. When Mob woke up, all of them, including Ritsu, were heavily injured. This is what caused him to reject his power and meet Reigen for guidance.
** He has a small one after seeing Ritsu [[spoiler:beat up a large group of delinquents with his psychic powers unprovoked, making him realize he had been unconsciously ignoring his brother's insecurities all this time until the issue boiled over.]]
* NiceGuy: Very kind and forgiving. Upon defeating former bad guys such as Dimple and Teruki, Mob even asks Reigen if it was wrong to just come and ruin their lives like that. At a different point, he even [[BerserkerTears sheds tears]] due to having to hurt a guy ''who is out to kill him''.
* NightmareFace: His expression when he encountered [[spoiler:what appeared to be the burning corpses of his family]] after [[spoiler:Claw invaded his house]] is a clear and VERY disturbing [[https://i.redd.it/50qbsxqk2ri21.jpg example]].
* TheNondescript: Mob is noted to look much like a random extra in a crowd shot (aka a [[MeaningfulName "mob" character]]).
* NonstandardCharacterDesign: While regular Mob is drawn in the same simple, cartoony fashion as everyone else, Studio BONES draws [[SuperMode 100% Mob]] more angularly and with more detail to resemble a character from a more traditional shounen battle manga. The most dramatic case is 100% Courage Mob, which is accompanied by an ArtShift so drastic that even the characters themselves are wondering who this new kid is.
-->'''Mogami:''' You're not the same boy as before. Who are you?
-->'''Dimple:''' Don't you get it? This is the true form of Shigeo Kageyama he only reveals when he's truly piss--Wait, actually, yeah. Who ''are'' you?
* NoSenseOfHumor: Not for a lack of trying. Not even intentionally letting Dimple's laugh-inducing mind control through his barrier had any effect on him. [[spoiler:He finally laughs in Chapter 101 after accidentally sending Reigen's birthday cake flying into his face with his powers.]]
** Downplayed: During the Mogami arc, he cracks a joke--his first in the series--with Dimple, marking a milestone in his emotional growth.
* OlderThanTheyLook: Mob realistically resembles a 14-year-old, but is often surrounded by people who look much older than their age, making him seem young in comparison.
* OneManArmy: Is able to trounce groups of baddies with his psychic powers alone.
* OnlyFriend: To Reigen, though Reigen only realizes this during their brief separation. [[spoiler: This gets subverted when Reigen forms new friendships with Serizawa, Dimple and Tome]].
* PartTimeHero: Quite literally, though spirits are not enough of an immediate or significant danger to cause him any SamaritanSyndrome.
* PersonOfMassDestruction: When Mob's psychic powers flare up, there might be some collateral battle damage, but when ???% shows up, it gets far worse. [[spoiler:Chapter 100 shows that ???% walking through Salt City causes phenomena mistaken for large-scale windstorms and earthquakes, to the point that an evacuation order comes into effect, not to mention leaving a visible trail of dug-up Earth where he walks.]]
* PopCultureIsolation: InUniverse, he's stated to be completely out of the loop when it comes to pop culture, as well as other trends like urban legends. This ends up being a major advantage when he's facing the Kuchisake-Onna/the Dragger, who gets her power from [[ClapYourHandsIfYouBelieve people's knowledge and fear of her]]; because he isn't up to date on such things and doesn't know anything about her, he has no reason to be afraid of her.
* PowerIncontinence: While unconscious, Mob's power level becomes incomprehensible. He also drives his powers towards infinity in a blind rage once he walks up to what looks like the [[spoiler:corpses of his family]], but Dimple manages to convince him they're fake and calms him down.
* PowerLimiter: More metaphorical than most examples: subconsciously [[EmotionSuppression suppressing his emotions]] keeps his powers in check, as does his kindness and Reigen's advice not to use his powers on other people. Building up an emotional charge that exceeds his ability to hold it back trips the limiter.
** Also consciously self-imposed, in that he tends to roughly match his psychic strength to that of his [[spoiler: human]] opponents to avoid ''killing'' them--he uses just enough strength to end fights. There are ''[[CurbStompBattle exceptions]]''.
** His consciousness itself is a limiter. Knocking him out releases the full extent of his powers in uninhibited [[SuperpoweredEvilSide ???% form]].
* PowerStrainBlackout: Overusing his powers can take a toll on his already weak constitution, and his emotional explosions are often followed up by fainting spells, temporary paralysis, or a compromised immune system.
* PubertySuperpower: While Mob had psychic powers since birth, they start growing rapidly when he hits his early teens, to the point that his EmotionSuppression begins to fail and cause his [[SuperMode Explosions]].
* PreAsskickingOneLiner: Deconstructed. The line he says just before obliterating Dimple, while badass, is more of a TearJerker because you can just tell that Mob is actually disgusted with himself and the stuff he can do when he goes out of control.
-->''"I'm... terrible."''
* PsychicPowers: He's very proficient in [[MindOverMatter telekinesis]] even when not trying, can make psychic barriers and also [[PowerCopying imitates any abilities]] he sees his opponents perform.
* PsychoactivePowers: His power is shaped by his mindset and overall worldview, and growing out of his EmotionSuppression and self-fear results in more positive, constructive "explosions" such as [[SuperEmpowering 100% Gratitude]].
* RageAgainstTheMentor: Mob eventually has a falling out with Reigen when working with him puts a strain on his social life. They reconcile soon after.
* RedBaron: The former LOL cult members call him "Psycho Helmet" and the students at Salt Mid and in other delinquent gangs around the district know him as "White T Poison". [[spoiler:Dimple later takes the Psycho Helmet identity for himself when he takes over the cult.]]
* RedEyesTakeWarning: In the anime, Mob's natural eye color as shown in a closeup while being [[spoiler:choked by Teruki]] is a deep reddish-brown. When he hits some of his explosions, like 100% Rage or 100% Hostility, they start glowing a vibrant and menacing red.
* RelativeButton: Anyone who [[BigBrotherInstinct harms Ritsu]] is making a grave mistake if Mob knows about it. [[spoiler:To put that into perspective, Mob always had a gradual build up to his 100% emotional outburst. The arc prior, it took Teruki almost strangling him to death to bring out his powers. By comparison, Mob goes from 0-100% in the matter of seconds after seeing Koyama beat up Ritsu.]]
* RepressionNeverEndsWell: As can be seen from his explosions. [[spoiler:It also turns out that ???% isn't some separate eldritch entity sleeping inside him, but simply the [[SecretlySelfish repressed feelings and base impulses he's too ashamed to acknowledge]], a realization that nearly breaks him.]]
* TheRuntAtTheEnd: He's by far the scrawniest, frailest member of the Body Improvement Club, and he's often shown lagging far behind them on their daily runs.
* SecretlySelfish: Like most of his emotions, Mob tends to suppress his more selfish and uncharitable impulses. [[spoiler:So much so that said impulses became their own entity in the form of ???%, who considers Mob a fabricated persona that has outlived its usefulness.]]
* SelectiveObliviousness: He has a huge blind spot in regards to Reigen's obvious PhonyPsychic act, even when other characters spell it out to him. [[spoiler:The final arc reveals that he subconsciously picked up on it a while ago, but is too scared of the implications that his most formative relationship is a complete lie to actually process it.]]
* SexierAlterEgo: [[https://vignette.wikia.nocookie.net/mob-psycho-100/images/2/25/Courage.gif/ 100% Courage]], which character design notes jokingly refer to as Mob's "ikemen" form.
* ShounenHair: Hitting 100% throws his hair into complete disarray, making him look like a scrawny little Super Saiyan.
* SicklyChildGrewUpStrong: While he never does get those muscles he was dreaming of, the Body Improvement Club does a great deal to help his anemia.
* SociallyAwkwardHero: At home and in school he is usually reserved and a bit awkward, even anxious at times, during social interactions. To wit, his "speech" when coaxed into running for Student Council President was an unprecedented 5 minutes of silence.
* SplitPersonalityMerge: [[spoiler:The series climax is Mob and ??? coming to an understanding, with Mob finally accepting his powers as part of what makes who he is and they were instrumental to his growth and the friends he got along the way, rejecting his previous wishes of ever wanting to be a person without psychic powers; Mob fully unlocks the path to free all his emotions, after going through the final trial of being rejected by Tsubomi he grows up, months later by the end of the series Mob has become the best version of himself, happy with all of him, laughing with joy for what he knows will be great days ahead]].
* SquishyWizard: While unrivaled in pure psychic ability, he's shown to be incredibly out of shape. His time as the newest member of the Body Improvement Club is mostly comprised of him passing out during their morning jogs. [[SubvertedTrope However]], this is only an issue in his everyday life--in combat, Mob is perfectly capable of raising psychic barriers stronger than steel and infusing his body with psychic energy to make himself much stronger. In the latter half of the series, he's [[CharacterDevelopment grown out of the trope entirely]]--while he's pretty far from matching the other members of the Body Improvement Club, his strength and stamina are hinted to be above average at least. In an aversion of HardWorkHardlyWorks, solely psychic-enhanced muscles turn out to be inferior to a mix of psychic power enhancement '''and''' conventional training, which should make Mob a better combatant as well.
* StockShonenHero: Mob is an inversion--instead of being HotBlooded and cheerful, he's emotionally repressed and usually a bit downbeat. Instead of spiky hair all the time that gets spikier the more power he uses, his hair is only spiky when his powers flare up and is usually styled into a rounded bowl cut. Instead of having lots of confidence and lots of friends, he starts the story with very little self-confidence and relies on what few friends he has to keep it from collapsing entirely.
* TheStoic: Mob is usually expressionless by default, and doesn't have much of a sense of humor. After his CharacterDevelopment, however, he gets better at interacting with others and smiles more often.
* SuccessfulSiblingSyndrome: While Mob doesn't resent Ritsu for his effortless success at school, being the under-performing brother of Salt Middle School's star student does not do favors for his self-esteem.
* SuddenEyeColor: His eye color (dark red) only becomes apparent during his explosions.
* SuicidalPacifism: Early on. Knowing how dangerous his powers are, Mob refuses to use them on other humans. [[WhatMeasureIsANonHuman Exorcising ghosts is fine, though, because it benefits Reigen]]. It takes a while for him to question whether or not that is right.
* SuperEmpowering: 100% Gratitude. [[spoiler:By the time he faces off against the leader of Claw, he's learned how to do this at below 100%.]]
* SuperLoser: He may have won the SuperpowerLottery, but missed out on just about anything actually useful in his daily life.
* SuperMode: 100%. Here, his powers become much stronger due to the force of his emotions, allowing him to keep up with exceptionally powerful espers.
* SupernaturalFloatingHair: His most distinctive characteristic when hitting 100%.
* SuperpoweredEvilSide: ???%. It comes out when Mob is unconscious, and not only seems to be almost a separate entity from Mob, but is also far more destructive, although it doesn't seem actively malicious, just less restrained in its power use than Mob. [[spoiler:To wit, ???% is so focused on getting to Mob's meeting with Tsubomi that it completely ignores the fact that its presence is pretty much ''destroying Salt City''.]]
* SuperpowerLottery: He's hit the absolute jackpot as far as psychic powers go. Too bad he's more interested in being a SliceOfLife protagonist than a [[ShonenDemographic shounen]] action hero.
* TrademarkFavoriteFood: His favorite food is takoyaki and his favorite drink is milk.
* TranquilFury: Even at 100% Rage or 100% Animosity, the only outward sign he's angry is a DeathGlare. That, and the way property damage starts to accumulate around him.
* UnconsciousObjector: Mob is able to keep fighting when knocked out. His power level when he's unconscious? '''"[[ReadingsAreOffTheScale ???%]]"'''. He's terrified of what could happen when he loses control like that. When [[spoiler:Mogami destroys Mob's body... the ???% ''[[http://vignette3.wikia.nocookie.net/mob-psycho-100/images/a/a6/Unidentified.png/revision/latest?cb=20160812195426 still takes form]].'' If Mob's physical body is obliterated, then ???% gets unleashed fully. ???% has thoughts and a personality of its own, though seemingly in service to Mob, as it states that because Mob going to see Tsubomi is an important meeting for him, and because Mob has been knocked out from being hit by a car, ???%'s intervention has become necessary and it won't let anything get in its way, including picking up the bouquet Minegishi gave him.]]
* TheUnfavorite: While his parents do love him, he seems to be this compared to his much more classically gifted younger brother, particularly in the eyes of his mother. As a result, Mob envies Ritsu for being a normal kid, which blinded him to Ritsu's resentment for having the incredible psychic powers he craves.
* UnwantedFalseFaith: Former members of the LOL cult decide to start a new cult worshiping him, which he has no desire to engage with despite Mezato's pestering.
* UnskilledButStrong: Mob doesn't have a lot of refined techniques the way most elite Claw members do, but his power advantage is so overwhelming that it rarely matters.
* UsedToBeMoreSocial: He was a lot more expressive and social as a small child. Then the accident with ???% happened, leading him to emotionally shut down and isolate himself.
* WackyParentSeriousChild: While not actually parent and child and he does have actual parents who don't fit this trope, his dynamic with Reigen resembles this.
* WarriorTherapist: Many of the psychics Mob fights end up being on the receiving end of having their insecurities thrown in their faces as Mob destroys them.
* WeirdnessMagnet: It is sort of justified when it comes to evil spirits; after all, his part-time job involves exorcising them, and while some of them end up being fakes, some are bound to be real.
* WhatBeautifulEyes: In the anime, his eyes are drawn in a shiny {{bishonen}} fashion during 100% Courage.
* WhenHeSmiles: He smiles frequently (and adorably) enough, but it's an absolute joy to see him [[spoiler: laughing brightly]] in Ch 101.
* WorldsStrongestMan: Mob is demonstrated to have the strongest psychic powers displayed thus far in the series, with only powerful espers like Toichiro Suzuki and Keiji Mogami giving him an actual challenge. The young boy still holds himself back with his ???% which vastly increases his already godlike psychic powers, though he can only use it when he's unconscious. For reference, Suzuki had been storing power '''for twenty years''' in preparation for his attempt at world domination. Mob has not even been '''alive''' for twenty years and has presumably not been consciously storing any power, but was still able to fight the Claw leader on equal ground.
* WouldntHitAGirl: In his fight against Tsuchiya at Scar HQ, he reveals that this is one of the morals that Reigen taught him. It takes her pointing out that [[WouldHurtAChild she's an adult woman fighting a middle school boy]] to get him to actually retaliate.
