Why does Shigaraki smile? A deep dive into the tragic backstory of My Hero Academia‘s complicated villain
Hey friend! Terry here, resident tech and data expert at 33rdsquare. Today I want to take an in-depth look at Tomura Shigaraki from My Hero Academia – specifically, the psychological significance behind his unsettling grin.
As a fellow MHA fan, I know you‘ll appreciate this deep dive into what makes Shigaraki tick. Strap in for an intense character analysis!
Shigaraki‘s Origin Story: The Making of a Villain
Shigaraki didn‘t just wake up one day and decide to become a villain. He was carefully groomed for the role by All for One, the series‘ overarching antagonist.
All for One rescued Tenko Shimura from his abusive home and took him under his wing. He encouraged Tenko‘s hatred of heroes who failed to save him.
This seeded Shigaraki‘s warped worldview that heroes are false idols and society is rotten to the core. With All for One‘s guidance, Shigaraki was set on the path to becoming Tomura – successor to All for One and leader of the League of Villains.
The Psychologically Damaging Effects of Child Abuse
Shigaraki‘s traumatic childhood of neglect and abuse inflicted psychological wounds that never properly healed.
Studies show childhood trauma can cause:
- Attachment disorders
- Impulse control issues
- Cognitive distortions
- Misplaced aggression
All of which apply to Shigaraki. His loathing of heroes stems from misplaced blame for not rescuing him from his home life.

The lack of intervention set Shigaraki on a path to perpetuate an abusive cycle. If not for All for One‘s influence, perhaps he could have been rehabilitated.
Shigaraki‘s Obsessive Behaviors Stem from Trauma
Shigaraki exhibits compulsive habits like neck scratching, lip scratching, and hair pulling. These obsessive-compulsive tendencies are coping mechanisms for past trauma.
Scratching and tearing at his skin could reflect subconscious rage against his abusive parents who neglected his needs. Ripping out his hair may be an effort to purge those traumatic memories from his mind.
Unraveling the Mystery of Shigaraki‘s Origin
Fans have speculated about Shigaraki‘s true lineage given his connections to Deku. Some theorize he could be Deku‘s older brother with All for One as their shared father.
This would explain why All for One called Shigaraki his "little brother" and it feeds the rivalry narrative between Shigaraki and Deku.
While unconfirmed, the connections are intriguing. Maybe Shigaraki subconsciously sees Deku as the brother he never had – driving his obsession with destroying Deku‘s worldview.
Peeling Back the Mask: Analyzing Shigaraki‘s Visual Design
Shigaraki‘s disheveled appearance exposes his mental state:
- Dry, cracked lips – Dehydration from neglect
- Excoriations around neck and mouth – Compulsive scratching
- Messy hair – Lack of care for personal appearance
- Disembodied hands costume – Symbolic of past trauma
His entire look screams troubled psychology. It‘s a stark contrast to Deku‘s put-together heroic image.
The Echoes of Trauma Haunting Shigaraki
In the heat of battle, Shigaraki is prone to experiencing trauma flashbacks. Images of his past abuse and family murder surface when triggered by violence and chaos.
This causes Shigaraki to lose control, descending into childlike tantrums and scratching fits. It‘s clear the trauma still festers under the surface even as an adult.
Imagining a More Hopeful Future for Shigaraki
While Shigaraki has committed unforgivable acts, I can‘t help but mourn the child he used to be. With proper support instead of manipulation by All for One, could he have turned out differently?
Perhaps there‘s still a chance for redemption. We‘ve seen glimpses of remorse, restraint, and humanity in Shigaraki despite his villainous path.
Only time will tell whether the boy Tenko still exists somewhere within the monster Shigaraki has become.
Let me know what you think! I‘m always down for an in-depth MHA chat. This is just the tip of the iceberg for analyzing Shigaraki‘s complex and fascinating character. Looking forward to geeking out together!
Your friend,
