Shigeo Kageyama

Shigeo Kageyama (影山茂夫, Kageyama Shigeo), nicknamed "Mob" (モブ, Mobu) and "White T-Poison", is the main protagonist of the Mob Psycho 100 series, as well as assistant and disciple of Arataka Reigen. He is the newest member of the Body Improvement Club.

Appearance
Mob has dark bowl-shaped hair. He is usually seen wearing the Salt Middle male uniform, the typical gakuran outfit. Mob has a rather nondescript expression on his face.

Personality
As a child, Mob learned that his psychic power was linked to his emotions. Strong negative emotions can cause him to hurt others, something he strongly dislikes and avoids (as shown in the 7th Branch Infiltration Arc where, after going 100, he hurts several teenagers). Therefore, he generally tries to keep his emotions in check. However, in some cases, he can control his powers as seen when he was at 100% courage.

He is also rather socially awkward. He is incapable of "reading the atmosphere", which has lead to him having a lack of friends.

However, Mob is very compassionate. He is forgiving, kind, and helpful. He tries to be kind to others in many instances. In the Mogami Keiji Arc, he lives for half a year in a fantasy world created by the bitter, former psychic, Keiji Mogami. There, he is friendless, without a family or anything else. Despite that, it takes great emotional manipulation, along with physical harm, for Mogami to make Mob become angered with his tormentors. Even then, he wants to offer them forgiveness.

He is also morally opposed towards using psychic ability against other people. He is, however, willing to cast this principle aside in cases of emergency, such as when his brother, Ritsu Kageyama, is kidnapped.

Another principle of his is that psychic ability does not make him or others inherently better and that his psychic ability is not something that he requires in life. This belief leads to conflict between him and Teruki Hanazawa, Keiji Mogami, Touichirou Suzuki and even his own brother, Ritsu Kageyama.

History
Before meeting his master, Arataka Reigen, Mob was frightened of his own abilities and was looking for a guiding force to follow. He soon learned from both Reigen and his childhood crush, Takane Tsubomi, that his psychic ability did not make him inherently greater than anyone else. He also learned that psychic ability should not be used against other people. This philosophy leads him to where he is currently and is one of the many defining traits of his.

Physical Abilities
Initially Mob was extremely physically unfit and incapable, having no bodily coordination, a lack of stamina and surprisingly low muscular strength. However, after joining the Body Improvement Club, his physical capabilities have grown greatly, although they are still relatively below average for someone his age.

Psychic Powers
Mob has a tremendous capacity for storing psychic power, which he primary uses to fuel his already existing powers. Due to a childhood incident he subconsciously sealed away most of his power behind several emotional locks, that will occasionally burst out when a particular emotion reaches 100% and overflows. The emotions so far shown include anger, sadness, hostility, gratitude, courage, tenacity, friendship, ecstasy, shame, compassion, kindness, and resignation. This however is only a fraction of his true power, which can only come out when he is completely unconscious and acting on survival instinct alone, only seen in the ???% mode.


 * Spiritual Awareness: Mob can sense the psychic energy of spirits and other espers. He has been shown to be able to widen his "antennae" up to 20 kilometres in order to sense the presence of other nearby espers.


 * Telekinesis: Mob possesses immeasurably potent telekinesis. With it, he can move extremely heavy objects, such as entire buildings, pin an entire crowd to a ceiling, create nearly impenetrable force-fields, fly, augment his physical strength and speed, disassemble matter and reconstruct it on a molecular level.


 * Psychic Energy Absorption: Mob possesses the ability to drain energy from other espers, energy-based attacks aimed at him, and even the environment around him and add it to his own. So far, Mob only exhibited this ability while at 100% or at ???%. When absorbing energy that originated from other espers, he can also absorb some of their emotions. This is shown when Mob absorbed Katsuya Serizawa's attack and felt his sadness. It is even possible for the emotion that he absorb to overwhelm him to the point that he feels that emotion at 100%, such as when he absorbed Touichirou Suzuki's attacks and entered Ecstasy 100% due to his influence. Mob has been shown to subconsciously exhibit this ability while in ???% mode.


 * Psychic Energy Transference: He has the ability to energise others with his power, both espers and non-espers. In the case of the latter, it bleeds out quickly since their bodies can't contain his power for very long, and is of limited use unless the person already knows how to use psychic powers. Although, even a non-esper can have a protective field of energy shielding them from other psychic powers for the duration of this effect. This is first shown when he reaches Gratitude 100% and temporarily relinquishes his powers to Reigen. He is also able to transfer his memories and emotions along with energy, as shown when Mob relayed his feelings of friendship to Katsuya Serizawa. Later on, Mob is shown using this technique without being at 100% when he recharged Shou Suzuki's energy after the latter's fight against his father.


 * Astral Projection: Mob can will his soul/spirit to leave his physical body. He can also enter the bodies and minds of others, though whether or not he can completely possess people is currently unknown.


 * Chlorokinesis: Mob eventually learns to imbue his psychic energy into plants enabling him to manipulate them and cause them to grow and mature at will.


 * ???%: A special state in which Mob occasionally enters when he becomes unconscious. It is a power that seemingly exists separately within Mob, as destroying the vessel that contains it, such as when Mob's body was destroyed by Keiji Mogami, unleashes it. In this state, Mob is much more powerful than he is normally, being able to easily overwhelm even the likes of Keiji Mogami. His ability to absorb energy is increased as he can absorb the energy from other espers and the atmosphere around him without the need of getting into close proximity to the source. It is also possible to enter this form while Mob is conscious, or if Mob is trapped in a place where he cannot use his psychic powers, as both were the case while Mob was in Mind World of the Devourer. This implies that ???% is not a part of Mob's regular psychic abilities. XXXX (presumably the Devourer himself) later comments that "[Mob] is no regular person".

Quotes
