My Hero Academia Episode 37: Katsuki Bakugo: Origin

The final practical exam begins with Izuku, Katsuki, and their teacher, All Might. Izuku tries to formulate a plan for escape, but Katsuki refuses to cooperate, insisting he will defeat All Might alone. Izuku attempts to persuade him, but Katsuki strikes Izuku and demands he stop talking. Their argument is interrupted by a powerful attack from All Might, originating from the escape gate on the opposite side of the replica city. The force of the attack tears up the street, alerting them to his presence.

All Might leaps into action. Izuku flees, but Katsuki stands firm, using his Stun Grenade technique to blind All Might before moving to attack. All Might stops him by grabbing Katsuki's face. Katsuki focuses on rapidly using his explosions to counterattack, but they are not powerful enough to hurt All Might. All Might slams Katsuki into the ground and then swiftly moves behind Izuku. Izuku instinctively retreats, reminded of a previous villain's charisma. However, Katsuki simultaneously moves to attack, and the two students collide. From the monitoring room, a female observer notes that Katsuki wants to win, while Izuku is only thinking of fleeing.

Katsuki recovers and walks back towards All Might, despite Izuku's pleas. Katsuki states he will win because that's what it means to be a hero. These words make Izuku recall their childhood together, and he pleads with Katsuki again. Katsuki refutes him. All Might suddenly pins Izuku down using a piece of a fence. Katsuki is too slow to react and is sent flying by All Might's subsequent punch, which makes him vomit. As Izuku watches, he remembers watching a video with Katsuki as young children, showing All Might defeating four villains at once. Katsuki was excited and inspired because All Might always found a way to win. Izuku admits to himself that he has always admired Katsuki's will to win.

All Might confronts Katsuki, deducing that Katsuki has been fighting hastily due to anger over Izuku's improvement. He tries to encourage Katsuki to realize his potential, but Katsuki states he would rather lose than work with Izuku. All Might decides to finish him off, but Izuku swiftly intervenes, punching Katsuki away. Izuku yells at Katsuki never to say he would rather lose, then grabs him and retreats into a back alleyway. Katsuki makes Izuku put him down, and Izuku pleads one last time for Katsuki not to give up, saying it's not who he is. Izuku recalls a time when, as a first-grader, Katsuki defended himself against two older kids because he believed the most amazing hero always wins.

Though angered, Katsuki reluctantly agrees to work with Izuku to achieve victory. When All Might passes their alleyway, Katsuki jumps out and distracts him. This gives Izuku an opening to get behind All Might and use one of Katsuki's grenadier bracers to blast All Might with a large explosion. They then flee at top speed towards the escape gate using their Quirks.

All Might is impressed with their teamwork, understanding that fixing their tandem relationship is a long-term task. He is determined to use this exam as a starting point for them and promises to do his best to school them. As the boys run, Katsuki states he knows the attack didn't faze All Might and declares he will blast him next time. Overhearing this, All Might instantly catches up to them and questions Katsuki's next plan before quickly breaking both of the grenadier bracers. He knees Katsuki into a nearby building and grabs Izuku. When Katsuki recovers and tries to rush All Might, the hero slams Izuku into Katsuki, pinning them both down. Katsuki ponders All Might's overwhelming strength and admits that All Might is the world's most unstoppable force.

Facing this adversity, Katsuki realizes he must push himself to overcome this obstacle. He uses his explosions at maximum output to blow All Might away. Katsuki then grabs Izuku and sends him flying towards the escape gate. All Might counters with a powerful smash that nearly breaks Izuku's back. Katsuki flies at All Might, admitting he was foolish for believing he could fight without taking risks. He blasts All Might with more super explosions, constantly injuring himself in the process. Izuku moves slowly towards the escape gate due to his injury, knowing that All Might will have to stop him, giving Katsuki an opening. However, when Katsuki capitalizes, All Might ultimately defeats him. Even so, Katsuki bites down on All Might's hand, refusing to accept that he cannot win the way he has chosen, even if it means destroying himself.

Inspired by Katsuki's resolve, Izuku leaps into action and hits All Might with a smash. He quickly grabs his partner and makes for the escape gate. All Might notes that Izuku could have escaped alone, but it has always been part of his being to help those in need. He says that in those moments where Izuku is rescuing others, there isn't an obstacle hard enough to stop him. Together, Izuku and Katsuki pass through the gate and pass the exam.

In a medical office, a female healer heals Izuku and Katsuki while scolding All Might for hitting them too hard. All Might muses over the boys' performance, proud that they can both grow stronger because they smile in the face of adversity. Meanwhile, at a hideout, a shadowy figure questions another character's interest in Izuku. A man with a scarred face interrupts them and introduces two new individuals to the character. One of the new individuals tells the character that he looks much grosser in person, and the other expresses excitement to join the group.
