A Shocking Decision: The Psychic Child's Sacrifice
- When the League of Villains attack the forest camp and attempt to abduct the U.A. kids, Mob will rise up and offer to be taken to their base on the condition that they don't harm anyone. He even states that he's eager to talk with Shigaraki again which would spark the grim leader's interest.
- Additionally, either Bakugou or Izuku would be taken to the villains' lair alongside Mob. The former wouldn't stand the idea of Shigeo giving in to the villain's demands and would try to attack them head on, only to be knocked out and imprisoned by them. For the latter, he wouldn't feel right about his blood brother being held prisoner and would fight to protect him so he wouldn't be a failure hero. Only to end up being taken hostage.
- Confirmed with Mob sacrificing himself to keep his friend safe. Though neither Izuku or Bakugou join him as they were prevented by Mob's psychic energy.
Rejection of Villainy: Shigaraki's Path to Healing
- If Shigeo is successful in talking to him and offering him healthier alternatives for his suffering, Shigaraki may very will lose the will to follow All For One's wishes and would break away from the League of Villains as it's leader. However, this would also motivate the Dark King to find a new successor to replace him.
Unfathomable Power: Return of the Unknown
- During the grand battle between All Might and All For One, Shigeo will be knocked out and the stress from the ongoing battle will result in the emergence of his unknown self. While this would make battling (and defeating) the Dark King much easier, the uncontrollable powers emitting from ???% would also lead to All Might and the other heroes having to fight him to keep the city from being destroyed.
- Jossed. On Discord, the author mentions that ???% will appear farther into the story, meaning that they won't appear in the Kamino Ward Arc. They instead appear in Kamino's Aftermath.
Mob Psychic: Super Star
- Shortly after defeating All For One while showcasing his endless powers, Shigeo will develop a cult following with many fans of the general public admiring him for his incredible hero potential. They would even go as far as to claim him as All Might's next successor. The boy may come to dislike this newfound popularity as they would still value him for just his raw power and not for his beliefs.
Give Peace a Chance! The Sorority of Societal Subversion
- During the All Girl Slumber Party in Chapter 34, the girls end up in shock and awe after discussing how Shigeo showed sympathy towards Shigaraki as he too knew what it was like to live in darkness. As many of them grew up in the Black-and-White Morality of heroism, this grand scene along with the other wonders performed by Shigeo will lead to many of the girls (particularly Momo, Tsuyu, Kendo and Ibara) to show a similar kindness to the future villains they come across. Along with that, they may very well question the true values of modern hero society and whether they will be part of that cycle or break away to create new changes.
The Master's Guilt: Reigen and the Devil
- Reigen and Serizawa will try to work directly with the ex-president in order to find a way to look for Mob. Touchirou was indirectly responsible for his disappearance and has the infinite power to look for him if necessary. So the Fox Man and the Bear will have to negotiate not only with the Fallen King but also the government agency holding him prisoner in the hopes of bringing their child back home.
Trial by Fire: Mob vs Dabi
- After learning about the depths of Shigeo's kind nature and how he's eager to offer redemption to those in need, Dabi would attempt to challenge the psychic's ideologies using his Dark and Troubled Past as Endeavor's discarded son mixed with his kill count of more than 30 civilians.
Blessing or Curse: The Most Dangerous Power Yet!
- Mob will eventually find a way to ''erase'' a person's Quirk. Either by manipulating their memories or how their body processes the activation of the quirk via signals, the esper will be able to render anyone that can be deemed too dangerous as Quirkless. This can benefit the heroes as it would render the greatest of threats powerless while also offering them an opportunity to reevaluate their lives without relying on their quirks.
An Artificial Esper: Shigaraki 100
- Assuming that Dr. Garaki will continue with his secret operation of amplifying Shigaraki's powers, then he may also give him some of Mob's DNA, which would have obtained prior to the operation, in the hopes of replicating his psychic abilities. If it's successful, then the new Shigaraki will have psychic abilities that will amplify his desire for destruction.
Bumo: the Runaway Nomu
- Dr. Garaki may be experimenting with creating Nomus that have the same powers as Mob by using his DNA. One of those Nomus will not only obtain those powers but will also obtain sentience and self-awareness. And wanting to learn more about themself and not be confined in the doctor's lab, the Nomu will escape and go on a quest of self-discovery. Maybe even try to track Mob after sensing how similar they are.
