Understanding the Shoto Todoroki Arc

Shoto Todoroki’s storyline is not confined to a single, neatly labeled arc. Instead, his character development functions as a backbone that runs through multiple seasons of My Hero Academia. From the earliest days at U.A. High School to the cataclysmic events of the Paranormal Liberation War, Todoroki grapples with his father’s legacy, the trauma of his upbringing, and the slow process of accepting the fire quirk he inherited from the man he resents most. This episode guide collects the indispensable chapters of that journey, spotlighting the fights, conversations, and quiet moments that define one of anime’s most compelling heroes.

The U.A. Sports Festival Arc (Episodes 14–25)

The foundation of Todoroki’s arc is laid during the U.A. Sports Festival, a televised tournament that forces him to confront his past in front of millions. The festival spans Season 2, from episode 14 through episode 25, and marks the first time viewers truly understand the weight of his lineage.

Setting the Stage: Obstacle Race and Cavalry Battle (Episodes 14–17)

Todoroki announces his dominance early. In the obstacle race (episode 15, “Roaring Sports Festival”), he freezes the ground beneath competitors and incapacitates robots with a single glaciation, showcasing raw ice power while deliberately avoiding his left side. During the cavalry battle (episodes 16–17), he teams up with Yaoyorozu, Kaminari, and Iida, using precise temperature control to immobilize rivals. Observers may note that he never produces flame, but it isn’t until later that the reason becomes heartbreakingly clear.

The Boy Born with Everything: Todoroki vs. Sero (Episode 18)

Matched against Hanta Sero in the one-on-one tournament, Todoroki unleashes a glacier so massive that it threatens the stadium structure. The victory is swift and overwhelming, but the anger behind the technique hints at something deeper. Even here, he refuses to call upon his fire, revealing the internal battle that will soon explode into the open.

Shoto Todoroki: Origin (Episode 23)

This is the definitive episode of the arc and arguably the single most important chapter in Todoroki’s entire story. His fight against Izuku Midoriya begins with freezing assaults that force Midoriya to shatter his own fingers to break free. Midoriya, however, sees the suffering hidden beneath the ice. He screams at Todoroki: “It’s your power, isn’t it?!”—challenging the idea that using his fire means surrendering to his father, Endeavor. That plea unlocks a flood of memories: a childhood spent watching his mother burn, the terrifying training sessions, and her desperate act that left his left eye scarred.

In a breathtaking moment of rebirth, Todoroki ignites his flames for the first time in combat, smiling through tears. The clash that follows destroys Cementoss’s concrete barriers and pushes both fighters to their limits. Todoroki loses the match, but he wins back a piece of himself. The episode lays the groundwork for every subsequent development in his character.

Aftermath and Final Match: Todoroki vs. Bakugo (Episode 25)

Though still emotionally raw, Todoroki enters his final match against Katsuki Bakugo. Hints of confusion linger—he hesitates, struggling to find the balance between his two halves. Bakugo, frustrated by what he perceives as half-hearted fire, demands a real fight. The encounter underscores a critical truth: accepting his flames is only the first step; learning to use them with full conviction will take much longer.

If you want to revisit the festival in full, all episodes are available to stream. The official catalog on Crunchyroll covers the entire arc, and the My Hero Academia Wiki provides a detailed breakdown of every match.

The Hero Killer Stain Arc and Internships (Episodes 26–33)

Todoroki’s development continues during the week-long internships that follow the Sports Festival. He chooses to intern with his father at Endeavor’s agency, a decision rooted not in admiration but in a pragmatic desire to master his flame without giving Endeavor the satisfaction of seeing his famous fire side. This arc confirms that Todoroki is actively wrestling with his new resolve, not merely having moved past it.

A Reluctant Apprenticeship (Episodes 26–28)

Endeavor’s agency is a brutal classroom. The Number Two Hero pushes his son relentlessly, but Todoroki’s attitude has shifted: he’s learning fire techniques on his own terms, much to Endeavor’s irritation. Small gestures—like using flames to heat bath water or warm his teammates—indicate a man slowly dismantling the mental barrier that equated his left side with his abuser.

Hosu City: Facing the Hero Killer (Episodes 29–30)

The true test arises when Todoroki receives a cryptic message from Midoriya and races to Hosu City. There he finds Midoriya and Tenya Iida locked in mortal combat with Stain, the Hero Killer. Todoroki’s entry into the alleyway is a model of tactical efficiency. He deploys ice to limit Stain’s movement while protecting his injured classmates, and when Iida’s bleeding arm needs cauterization, Todoroki uses his fire without hesitation to save a life—a quiet but significant rejection of his old vow.

The fight against Stain forces Todoroki to combine ice and fire under lethal pressure. He doesn’t win through brute force, but his support turns the tide. In the aftermath, the police chief praises the three students, and Todoroki feels a sense of heroism wholly unconnected to his father’s ambition.

Provisional Hero License Exam: Embracing Both Sides (Episodes 51–62)

Months later, during the Provisional Hero License Exam arc, Todoroki has visibly matured. The exam’s first stage (episode 59) pits him against Seiji Shishikura of Shiketsu High, a student who transforms flesh into malleable projectiles. Todoroki’s strategy reveals his growth: he now uses fire to create updrafts, manipulate visibility, and complement his ice attacks rather than treating fire as a shameful last resort.

The second phase (episode 62) throws the class against the veteran hero Gang Orca. Here Todoroki demonstrates simultaneous emission of fire and ice, cooling his body to offset overheating while dousing the battlefield in controlled flame bursts. It is the first public display of what will later become his signature “Phosphor” style—a fluid, athletic melding of his halves. Instructors note that Todoroki’s attitude has softened; he coordinates with teammates, offers encouragement, and no longer views his quirk as a curse.

Pro Hero Arc: A Son’s Resolve (Episodes 87–90)

The Pro Hero Arc in Season 4 brings the Todoroki family drama into the national spotlight. After All Might’s retirement, Endeavor becomes the new Number One Hero by default, and the weight of that title lands heavily. Todoroki is home when the villain High-End attacks, and he watches the broadcast of his father’s desperate, no-holds-barred battle alongside his siblings. The fight, spanning episodes 88 and 89, shows Endeavor pushed beyond his limits, burning with a determination that, for once, isn’t about surpassing All Might but about protecting people.

Seeing Endeavor nearly die shakes Todoroki. He doesn’t forgive his father—the scars remain—but the episode plants the seed of a complicated reconciliation. Todoroki later admits that he wants to see what kind of hero, and what kind of father, Endeavor can become. This arc also introduces the deeper mystery of the missing Toya Todoroki, which will later shatter the family.

For streaming these emotionally charged episodes, Funimation carries the entire series with both subbed and dubbed options.

Joint Training Battle: Solidifying His Power (Episodes 100–101)

Season 5’s Joint Training Arc provides a low-stakes arena for Todoroki to test his refined abilities against Class 1-B. His team—featuring Ojiro, Shoda, and Yanagi—faces a coordinated squad that pushes Todoroki to adapt quickly. In episode 100, he demonstrates far greater fire endurance, using short, concentrated bursts to disperse gas attacks and superheat the air without exhausting himself.

A pivotal moment occurs when Todoroki recognizes that his old habit of simply overpowering opponents leaves his teammates exposed. He consciously scales back, coordinating with Ojiro’s martial agility and Shoda’s Twin Impact quirk. The victory is a team effort, and Todoroki’s willingness to play a supporting role signals that he has moved beyond the lone-wolf mentality instilled by his father. His internal monologue reveals a new mantra: his power is a tool to save others, not a weapon to prove himself.

Paranormal Liberation War: The Todoroki Family Tragedy Unveiled (Episodes 114–126)

The war arc in Season 6 unleashes the most devastating revelation in Todoroki’s life. As the heroes raid the Paranormal Liberation Front, the villain Dabi confronts Endeavor on a live broadcast and reveals his true identity: Toya Todoroki, Shoto’s eldest brother, long believed dead.

Dabi’s Dance (Episode 123)

Episode 123 is a masterclass of horror and heartbreak. Dabi’s patchwork skin sloughs away as his blue flames rage, and he broadcasts his traumatic past to the world: Endeavor’s obsession with creating a child who could surpass All Might, the neglect that drove Toya to self-destructive training, and the fire that everyone thought had killed him. For Todoroki, watching this in real time, the broadcast reopens every wound. The father he was just beginning to understand is now vilified, and the brother he never knew becomes an enemy consumed by vengeance.

Shoto’s Response (Episodes 124–125)

Instead of crumbling, Todoroki makes a choice that defines his maturity. He flies to the battlefield to confront Dabi directly, not with rage but with grim resolve. He acknowledges the pain Toya suffered, but he also declares that he will stop him—because letting his brother incinerate innocents would make him complicit. The fight is brutal. Dabi’s flames far outmatch Todoroki’s, but Shoto uses his Phosphor technique to regulate his temperature and combine fire and ice into a sustainable counter. He can’t defeat Dabi alone, but his presence buys time and challenges Dabi’s narrative that the entire Todoroki family is nothing but a monument to Endeavor’s sin.

The war’s aftermath (episodes 130–131) includes a somber family reckoning. Shoto speaks with his father and visits his mother, who is still hospitalized. He tells her he wants to truly talk to Dabi—not to save him as a hero, but as a brother. These moments underline that Todoroki’s arc is no longer about rejecting his fire; it is about reclaiming his family’s broken bonds, however impossible that may seem.

Where Todoroki’s Arc Stands Today

The Dabi revelation pushes Todoroki into a new phase of heroism. He is no longer the boy fighting his father’s shadow; he is a young man facing the consequences of his father’s mistakes while forging his own definition of what it means to be a hero. The manga continues to develop this theme, showing Todoroki training to master the full potential of his Phosphor ability and aiming to become a hero who makes his mother smile—a quiet, personal ambition far removed from Endeavor’s ruthless climb to Number One.

For anyone who wants to stay current, the Viz Media Shonen Jump platform offers the latest chapters digitally, and the anime continues to adapt these storylines with high production value.
