My Hero Academia has captivated audiences with its intricate narrative and unpredictable storyline. Observant fans may have noticed various foreshadowing elements that foreshadowed significant plot developments. While it’s unlikely that creator Kohei Horikoshi meticulously planned every aspect from the outset, some vital story arcs appear to have been set in motion early in the series.
Throughout the series, not all foreshadowing is immediately apparent. Some hints perplexed viewers for years before their full context was revealed. With the conclusion of the series now at hand, it is the perfect opportunity to revisit the subtler moments that hinted at future events within the rich world of My Hero Academia.
1. The Vestiges Awaken
The Previous Users of One For All Help Midoriya Regain His Focus

- Episode: 20
During his match against Shinso in the Sports Festival, Midoriya finds himself unprepared for the challenge ahead. While adjusting to the overwhelming power of One For All, he faces Shinso, who wields a Quirk that can hypnotize opponents, thus gaining control over Midoriya’s actions. Just as Midoriya is about to involuntarily walk out of the arena, he experiences a surge of energy and sees shadowy figures that spark questions about his new Quirk.
This enigmatic moment wouldn’t be fully explained until the Joint Training Arc, where the concept of the Vestiges and the legacy of the previous users of One For All come into play for the first time.
2. Shigaraki’s Backstory
Hints of Shigaraki’s Tragic Past in the Hideout Raid Arc

- Episode: 47
The depths of Shigaraki’s backstory are officially unveiled during the My Villain Academia arc. However, clues to his troubled past appear earlier, notably in Chapter 91 of the manga. When All For One uses his portals to assist Shigaraki, he expresses concern that Shigaraki’s body isn’t ready and ominously states, “You will continue this war.”
A poignant manga panel captures young Shigaraki alone, reaching out to a mysterious figure, hinting at the emotional turmoil that shaped who he would become. These initial teasers add layers to Shigaraki’s character as fans come to understand his background over time.
3. Toga’s Accidental Reveal
Early Hints of Toga’s Quirk Potential

- Episode: 38
Initially, Toga’s ability to transform into individuals by consuming their blood is not revealed until later in the Provisional License Exam arc. However, her obsession with wanting to “be other people” presents subtle hints throughout the series. A particularly striking moment arises during her introduction in Chapter 68, where she exclaims, “I wanna be Mr. Stainy,”foreshadowing her capacity to assume identities of key characters.
4. “I’m Surrounded By Sickness”
Overhaul’s Ideological Foundations Foreshadowed Early On

- Episode: 65
Overhaul’s belief that society is plagued by “Hero Sickness”is articulated during his clash with Midoriya. Intriguingly, he first alludes to this perspective during his introduction, stating, “I’m surrounded by sickness, here, there, and everywhere.”At first glance, he might seem merely germophobic. However, these initial comments hint at a complex ideology rooted in his past experiences in an orphanage.
5. Dabi’s Revelation
Implications of Dabi’s Knowledge About Endeavor

- Episode: 90
Dabi’s dramatic revelation that he is Toya Todoroki, believed dead in childhood, is one of the series’ climactic moments. Before this shocking confession, Dabi exhibits knowledge of Endeavor’s identity that suggests a deeper connection. In a tense moment during Episode 90, he calls out Endeavor’s real name during a retreat. This revelation underscores Dabi’s true lineage and his past with the Todoroki family.
6. Star and Stripe’s Final Words
A Lasting Warning to All For One

- Episode: 141
In a decisive battle against Shigaraki, Star and Stripe delivers one last impactful message before her demise. Utilizing her Quirk that allows her to redefine the rules of her abilities, she declares that her Quirk will not cooperate with Shigaraki. This causes severe consequences for him, hinting at the potential for future heroes to thwart villains like All For One, reinforcing the notion that a true hero will eventually rise to confront such darkness.
7. Quirk Singularity Theory
The Emergence of the Quirk Singularity Theory

- Episode: 80
First introduced during the Remedial Course arc, the Quirk Singularity Theory suggests that as Quirks evolve, they may become dangerously potent. This theory becomes manifest during the climactic battle against Shigaraki, wherein his body struggles to stabilize amid the multitude of Quirks he possesses. This not only hints at the ramifications of Quirk accumulation but also sheds light on the importance of One For All’s legacy in growing stronger with each successor.
8. Aoyama’s Mysterious Absence
Aoyama’s Disappearance Raises Suspicion

- Episode: 10
In the lead-up to the final confrontation against Shigaraki and All For One, Class 1-A uncovers a traitor among them: Aoyama. Though fans receive subtle hints about his true loyalty throughout the narrative, his conspicuous absence during the U.S.J incident raises eyebrows. Aoyama had indeed been the one leaking information to All For One, which makes his initial cowardice in the face of imminent danger deeply significant.
This apparent benign behavior, masked as humor, becomes a clear indicator that all was not as it seemed, stirring intrigue around Aoyama’s character and motivations.
