Izuku Midoriya vs. Shoto Todoroki

Izuku Midoriya vs. Shouto Todoroki is a battle fought between  Class 1-A students, Izuku Midoriya & Shouto Todoroki, during the Sports Festival fighting tournament.

Battle
The battle starts with Izuku trying to strategize against Shouto. Shouto uses his Quirk Half-Cold Half-Hot and shoots pillars of ice towards Izuku on the ground. Izuku uses One For All on his middle finger and flicks it causing a shockwave of wind pressure that destroys Shouto's ice. Izuku then does the same thing again with his index finger to strike Shouto which hits him but Shouto creates ice behind him to prevent himself from being blown out of the ring. Shouto then uses his ice power on the ground and Izuku destroys the incoming ice using the wind pressure from his Quirk. Using the ice, Shouto creates a board of ice to get into the air with. He then uses his ice power on the ground again, knocking Izuku back and in the process causes Izuku's foot to become trapped in the ice. Shouto starts to attack the defenseless Izuku but Izuku creates another wind pressure attack which frees himself and knocks Shouto back. Shouto, noting that Izuku is in a critical position after seeing his broken fingers decides to end the battle and launches another wave of ice. However, Izuku fires another wind pressure attack destroying the ice and shocking Shouto. Izuku then taunts Shouto. Shouto, now angry, rushes at Izuku and Izuku reacts by ducking under and punching him in the stomach, which sends him flying back. Shouto then uses his Ice-Half on the ground and Izuku jumps to dodge it. Shouto then shoots more ice at Izuku, but he destroys the ice again. Izuku the rushes at Shouto and headbutts him in the stomach. During this time, Shouto remembers his mother's relationship with his father. As Izuku taunts him for not fighting at full power, Shouto starts experiencing the frostbite of his Quirk, causing his movements to become sloppy and allowing Izuku to attack Shouto more easily. After Izuku tells Shouto that his fire power belongs to him and not his father, Shouto activates his fire power. With Shouto's Hot-Half activated, he now declares he will become a hero and in the process his fire power heals his frostbite. In the stands, Endeavor yells about his son fulfilling his ambition. Izuku and Shouto launch themselves towards each other for one final clash. Before they could reach each other, Cementoss creates a cement wall to stop them, but they both break it using their Quirks and a great shockwave is sent through the stadium.

Aftermath
After the smoke clears the stadium, it is shown that Izuku was knocked back into the stadium wall passed the out of bounds line. This leads to the winner being Shouto. Izuku is then taken to Recovery Girl to get healed. It is there that All Might learns that Izuku fractured his entire arm and that it will possibly never heal properly.
