Mob's powers and abilities
At first glance, Shigeo is an average middle school student. Initially, Shigeo was very 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 grew greatly, although they are still relatively below average for someone his age. He isn't very skilled at his schoolwork either and gets flustered whenever teachers call on him to answer questions in class.
However, Shigeo's true strength lies in his phenomenal psychic powers, which outclass those of almost every other esper in the series. He is arguably the most powerful esper in the series, rivaled only by Keiji Mogami and Toichiro Suzuki. He has a tremendous capacity for storing psychic energy, which he primarily uses to fuel his already existing powers. Due to his belief that psychic powers are not to be used against others, he has done little combat training and does not specialize in any specific type of ESP. Despite this, he still has a wide variety of techniques at his disposal and is actually able to learn new techniques rather easily, as seen when he learned how to use chlorokinesis during his battle with the farm spirit, when he managed to project his spirit out of his body after only seeing it a single time, and when he learned how to track the energy of other espers when he entered his 100% Obsession state, something that Dimple noted. However, he still relies most heavily on simple things such as telekinesis and barrier creation in combat. Toichiro, who has traveled the world, never encountered an esper on Shigeo's level before.[3][4] Shigeo's psychic aura is usually blue, but can sometimes show shades of pink and purple. It also has a polygonal pattern.
Mob's Abilities

Telekinesis
Shigeo 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
Shigeo 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, Shigeo 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 Shigeo absorbed Katsuya Serizawa's attack and felt his sadness.[5] 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 Toichiro Suzuki's attacks and entered Ecstasy 100% due to his influence.[6] His holding capacity is extremely high as well, since he was able to fully absorb all the psychic energy Toichiro had released and still survived, although the process caused him great pain and he was barely able to survive. Shigeo has been shown to subconsciously exhibit this ability while in ???% mode.[7]

Psychic Energy Transference
Shigeo has the ability to energize 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. However, even a non-esper can have basic abilities such as a protective barrier for the duration of this effect. This is first shown when Shigeo reaches Gratitude 100% and temporarily relinquishes his powers to Reigen.[8] He is also able to transfer his memories and emotions along with the energy, as shown when Shigeo relayed his feelings of friendship to Katsuya Serizawa.[9] Later on, Shigeo is shown using this technique without being at 100% when he recharged Sho Suzuki's energy after the latter's fight against his father.[10]

Chlorokinesis
Shigeo eventually learns to imbue his psychic energy into plants enabling him to manipulate them and cause them to grow and mature at will.[11]

Spiritual Awareness
Shigeo 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.[12]

Astral Projection
Shigeo can will his soul/spirit to leave his physical body, appearing as a floating axolotl-like creature.[13] He can also enter the bodies and minds of others,[14] though whether or not he can completely possess people is currently unknown.
Shigeo's Progress Towards Explosion
100% Anger / Rage
1/16
Note: Shigeo's Meter measures his Amount of Psychic Powers being released rather than his Emotion or Heartbeat Rate, the % meter also has a connection to quickly releasing Psychic Energy in an Alarming or Steady Rate.
Due to a childhood incident involving his psychic powers, Shigeo has subconsciously sealed away his emotions as a means to better control his psychic abilities. However, there is a limit to how much of his emotions he can keep bottled up. Once he reaches his limit, all the power that he kept suppressed will explode out, giving him a significant boost in his psychic abilities.
The progression toward Shigeo's explosion is visually depicted with a percentage labeled "Shigeo's Progress Towards Explosion" that eventually reaches 100%. The more emotional stimulus that Shigeo experiences, the faster his limit will be reached. After Shigeo's psychic explosion has completed, the counter of his emotional limit will reset back to 0%.
When Shigeo explodes, how he uses his enhanced power depends on the emotion he felt when he reached his limit. The emotions that have been displayed at 100% so far include:
100% Anger / Rage - After being taunted by Dimple and the (LOL) Cult, and later after Toichiro attempts to kill Reigen and disrespects Serizawa. Resulted in Shigeo becoming serious about fighting.
100% Sadness - After going into ???% mode in his battle with Teru, resulting in the destruction of Black Vinegar Middle School.[15][16] Resulted in Shigeo crying and putting the school back together.
100% Hostility / Animosity - After watching the violent and callous treatment of Ritsu and the other middle schoolers by Koyama.[17] Resulted in Shigeo beginning a brutal beatdown of his attacker.
100% Rejection - While being forcibly shown an illusion of Ritsu in a pool of blood by Muto.[18] Resulted in Shigeo frying Muto's brain with psychic energy in retaliation.
100% Murderous Intent - Although not a true 100% state, this was very nearly achieved, reaching 99%. In this state, Shigeo became utterly ruthless and cold-blooded, prepared to kill his opponents as long as the people he cared about were safe, and he was shown wickedly smiling. Thankfully, Reigen stopped him at the last second, and his master's words changed his energy and emotions to 100% Gratitude.
100% Gratitude - When Reigen tried to protect Shigeo by telling him it was okay to run from the battle with the 7th Division.[8] Resulted in Shigeo temporarily transferring his powers to Reigen, who is at "1000%."
100% Courage - While fighting Mogami to save Minori Asagiri, and later while fighting Toichiro and resolving to fight to protect his friends and family.[19] Resulted in Shigeo gaining a more bishounen appearance. This is Shigeo's most powerful 100% state, since he was able to momentarily fight on-par with Suzuki at 100% while he was struggling greatly before with just 50% of Suzuki's power.
100% Tenacity / Obsession - After identifying the Claw espers who supposedly burned down his home and kidnapped his family. Resulted in Shigeo going on a single-minded rampage to track down said espers and find out where they took his family and how they made the dummies at his house.
100% Friendship - After learning about Serizawa's sad backstory and being willing to be his friend. Resulted in Shigeo absorbing Serizawa's energy blast and throwing it back at him to let Serizawa understand Shigeo's own sad backstory.
100% Ecstasy - While being influenced by Toichiro's own emotions of ecstasy during their battle.[6] Resulted in Shigeo laughing hysterically and flying erratically, enjoying the thrill of the battle. He momentarily allowed himself to get carried away in this state but stopped when he saw how scared Ritsu was when looking at him.
100% Shame - After realizing he let himself get carried away with his psychic powers in his battle against Suzuki.[20] Resulted in Shigeo groveling and hiding in the clouds.
100% Compassion - After realizing how sad Toichiro's life must really be and feeling sorry for him during their battle.[21] Resulted in Shigeo crying and trying to quickly crush Toichiro with buildings.
100% Resignation - After deciding that Toichiro could not be convinced to stop and that he had no other choice but to stop him by force.[22] Resulted in Shigeo brutally contorting Toichiro's body in an attempt to leave him physically unable to go on.
100% Kindness - After deciding to stay with Toichiro in his supposed final moments and attempt to save him from his ghastly fate. Resulted in Shigeo creating a barrier around himself and Suzuki and trying to absorb his energy overload.
100% Getting Carried Away - After noticing how many girls were talking to him and how much attention he was receiving compared to usual. It didn't result in any psychic occurrences, but led to Shigeo growing insensitive and disregarding Dimple's feelings when he was talking to him about the Divine Tree.
100% Trust - After deciding to not use his powers against Dimple in the Divine Tree and to trust him instead. Resulted in Shigeo temporarily throwing away his psychic powers.
???%
???% taking control
Main article: ???
"???%" is a special state that Shigeo occasionally enters when he becomes unconscious under extreme stress, or when his physical vessel is destroyed. When ???% is active, Shigeo can unleash all of his latent psychic power at once, allowing him to achieve a level of psychic strength that is far beyond that of his 100% Explosions.
The major downside of this power is that Shigeo completely loses control of himself while it’s active and his basic instincts take over. This runs the risk of Shigeo doing something that he would regret
Mob's weaknesses
Formerly refrained from killing or harming others with his esper abilities, especially women, although he loses this later in the series. Has to experience strong emotions to enter 100% mode and can be knocked out/incapacitated before reaching it | None notable | Can be reverted by Mob himself through him coming to terms with his alter ego, although this doesn't apply much to combat
