My Hero Academia intricately explores the nature of relationships and the drive to uplift others. Among its most complex characters is the main antagonist, All For One, whose motivations are intertwined with his brother, Yoichi, the inaugural user of One For All. All For One’s quest for One For All is not merely a quest for power; he aims to reunite with Yoichi’s vestige. However, this urgency raises questions about his character and motivations throughout the series.
In a pivotal moment in the final arc, Izuku “Deku”Midoriya forcibly transfers the One For All power to Tomura Shigaraki. This act begins the gradual fading of Yoichi’s vestige and the vestiges of other past users. Herein lies the contradiction: if All For One’s primary goal was to reconnect with his brother, his ruthless behavior seems inconsistent with that affection, particularly given that he consistently exhibits self-serving motives.

Dissecting the Character Inconsistencies of All For One in My Hero Academia

Kohei Horikoshi, the creator of My Hero Academia, portrays All For One’s ambition to dominate the world as a means to reclaim his brother Yoichi. He perceives Yoichi not just as kin but as a possession, which clashes with his established characterization. If All For One had emerged victorious against Deku and assumed control over Tomura Shigaraki’s body—with its dying vestiges—it raises the issue of his motivation: without Yoichi, can he sustain his desire for chaos and power?
This conundrum is exacerbated by All For One’s history; even during his imprisonment at Tartarus, he relished the havoc his actions stirred in the world. His delight in provoking All Might further complicates the notion that he would falter without his brother, suggesting a deeper, more complex motivational framework.
The Implications of All For One’s Complex Characterization

It’s plausible that Horikoshi intended to deepen All For One’s character, showcasing the significance of interpersonal connections. This nuance emerges clearly during his confrontations with Katsuki Bakugo, where he reflects on his disdain for the second One For All user, Kudo. Such insights present a multifaceted villain, previously understood as pure evil, revealing a man incapable of forming genuine connections and reducing others to mere objects.
This dramatic juxtaposition of All For One against characters like Deku and All Might magnifies the core themes of My Hero Academia, where the bonds between individuals are paramount. It portrays All For One as a tragic figure whose twisted impulses provide a stark contrast to the show’s heroes.
Concluding Reflections
The revelation about Yoichi’s influence has sparked considerable debate among fans regarding All For One’s characterization in My Hero Academia. Although his motivations are complex and reveal more depth, the execution leaves room for improvement in clarity. As the story progresses, it’s evident that All For One’s desires extend well beyond simply reclaiming his brother, but understanding these layers fully may require a deeper dive into the narratives presented within the manga.
