Shoto Todoroki: Origin

|No ones pov|
The fated duel between Izuku and Shoto has finally arrived.Y/n silently wishes both boys luck.As soon as the battle begins, Shoto leads with an ice attack, but Izuku counters with a Delaware Smash. Shoto creates a pillar of ice behind him to keep him from being blown out of bounds, as he expected Izuku to break his finger in order to negate the ice attack.

All Might comments that this was likely the only way Izuku could have retaliated. Izuku is forced to damage a second finger to stop Shoto's next attack and mulls over that he only has six more chances, and must find Shoto's weakness before he breaks all his fingers. Shoto doesn't let up and continues his onslaught of ice attacks.

In Class 1-A's section of the stands, Eijiro returns from defeating Tetsutetsu. He sarcastically compliments Katsuki and Shoto for having techniques that blast the whole stadium. Katsuki responds by explaining that Quirk's are physical abilities and can get worn out just like anything else. He takes a moment to ponder that this is the very reason he designed his costume in such a way so that he could go beyond his own limits.Y/n ponders on what happened during her own fight...She wanted to know more about the unknown voices she heard..

Meanwhile,Shoto's assault continues, forcing Izuku to break the last finger on his right hand. However, Shoto withstands the smash and creates a tower of ice to run up and close the distance between them. Izuku uses another smash to break the ice steps a part, but Shoto avoids it and nearly freezes Izuku at close range.

In order to break the ice that's slowly freezing him, Izuku sacrifices his entire left arm and lets off a full powered smash. Shoto withstands the aftershock of the smash using an ice blockade. While recovering, Shoto notes that this attack from Izuku was significantly more powerful the previous ones and that he realizes his opponent is trying to keep him at a distance. Izuku is startled by Shoto's combat awareness, and some viewing fans even comment that Shoto is already stronger than the average pro hero. 

Questioning Izuku's durability, Shoto asks if he's already too worn out from defending against the ice. Izuku doesn't respond, and instead he notices that Shoto is shaking because of the frost that building up on the right side of his body. Shoto apologizes for the intensity of the battle and thanks Izuku for helping him irritate Endeavor by only using ice rather then fire. Understanding that Izuku has no healthy fingers left, Shoto sends an ice attack at him that he expects to finish the match. However..
"IM NOT FINISHED YET!"
Izuku declares and uses his already broken finger to blow Shoto's ice away. 

"Izuku...please don't push yourself..."
Y/n said horribly worried for her brothers health seeing the condition his hands are in.

"Why are you going so far...."
Shoto asked.
"I was right....your body is trembling,You can only take being cold for so long...Quirk's are physical abilities." Izuku also surmises that Shoto could offset his temperature by using his fire, but knows Shoto refuses to do so. He challenges Shoto to put more effort into the battle, stating that everyone else is giving it their all while Shoto is only using half his power. Izuku provokes Shoto by claiming that he has yet to injure him in this battle, demanding that Shoto use his full strength. 

Agitated, Shoto rushes Izuku, albeit much slower than before. Katsuki notices Shoto's drop in mobility and assumes that it's because Shoto's stamina is running low after wasting so much of it fighting Hanta. Shoto closes in on Izuku, but as soon as he lifts his right foot to attack, Izuku controls All For One and strikes Shoto in the torso, sending him flying away. Shoto recovers and tries to use another ice attack, but it's much slower than the previous ones and Izuku is able to avoid it. They both move into closer quarters and fight in spite of their afflictions. Cementoss urges Midnight to stop the match because Izuku is fighting too recklessly by continuing to injure his already broken fingers with more smashes.
