The post about Tododeku being considered some kinda vanilla ship was taken straight out of my mind... Cos y'all know what happened right? Todoroki saw Izuku give no shits while throwing hands with a freaking genetic abomination and thought "Imma challenge this crazy mofo" and then he accused him of being a secret love child and followed it up with unloading tragic backstory(tm). After that they valiantly tried to murder each other on national TV, live...Izuku broke his everything and permanently disfigured his hand and Todoroki somewhat overcame a lifetime of trauma via talk no jutsu. They also blew up the arena by virtue of thermodynamics and almost killed everyone if it wasn't for an overworked cementoss. The next time we see them, they are ride or die. Todoroki just booked it to a shady alley to fight a serial killer cos of a freaking location ping. Then Shouto joined the Bakugou Rescue Squad(tm) cos Izuku said so..no questions asked. Let's not forget that Izuku, hero fanboy and anxious Duracell bunny stood up to Endeavour BEFORE he knew the tragic backstory(tm). Tododeku is just straight up ride or die. And the fact that people think they're a vanilla ship, platonic or romantic...just amazes me.... Cos these two would most definitely commit light recreational murder(tm) and call each other to for a cute evidence destroying and body hiding session.
You are right and you should say it.
I am very attached to the Todoroki/Midoriya fight because it's nothing short of insane.
It starts with Todoroki (accidentally?) eavesdropping Uraraka and Tenya mentioning that Izuku is eating with All Might. Similar quirk + Midoriya risking his life to save All Might (someone who shouldn't need help) and so he immediately put on the tinfoil hat.
Just before the Sport Festival starts, Todoroki challenged Midoriya, someone who can't use his quirk without breaking his bones, instead of Bakugou, aka the other strongest fighter in the class.
And Todoroki turns out to be right because the sheer possibility of Izuku using his quirk too close to him during the "Grab a headband" fight made him use his flames for a moment, which is a pretty big deal.
Todoroki then lures Izuku to an isolated area, it's the first time they actually talk to each other for real, and Todoroki proceeds to ask him if he is the Symbol of Peace's secret bastard child???
He then doesn't even give a second to Izuku to recover from it and tells this kid, that he has pretty much never talked with before, his entire tragic backstory.
As someone who protects their secret more fiercely than a dragon protects their gold, this one shook me more than the actual content of the tragic backstory. There is also the fact that it was a huge risk on Todoroki's part as it was possible for whoever listened to him not to believe him.
Izuku then sees Endeavor. I am not surprised about him talking back to him because Izuku has social anxiety but doesn't have much patience when it's more serious. And yes, from his expression, it's pretty clear he believed Todoroki.
Izuku goes to this fight mentally prepared to snap as many fingers as necessary to win. He doesn't have any other way to fight Todoroki.
Not only does he break many bones in this fight but he pretty much tells Todoroki "You ain't shit" because Todoroki never managed to hit Midoriya. All his damage is self inflicted so far.
At some point, Todoroki wonders if his dad has paid Midoriya to convince him to use his fire, which is very funny to me.
Izuku actually directly punches Izuku with OFA at some point, which is a pretty good deal as at the time, he avoided it in order not to turn his opponents in chunky salsa.
"IT'S YOUR POWER!"
Enough said.
Once the flames were unleashed, they both decided to just unleash their full power on each other.
That something they didn't even do in the USJ, while fighting villains.
You said that an overworked Cementos is the reason why they didn't killed everyone by the virtue of thermodynamic but since the walls were created were vaporized, I am more leaning towards their attacks cancelling each other.
And don't forget how they didn't really talk to each other during this fight, and yet, they quickly understood what the other was trying to say and why they were doing this.
No, seriously, they shared a glance to say "Hey, want to beat the crap out of each other to evacuate some trauma?", the other mentally answered "Yes!" and the next thing Midnight knew, there was no more arena.
And that's just the Sport Festival.
