Katsuki is willing to fight himself.
Izuku has so many questions but he can't find his own voice while is being held by older Kacchan.
Aizawa regrets told Bakugou about it.
Drunk izuku : Kacchan, you’re the love of my life, I can’t imagine a life without you with your dumb crimsons eyes, your amazing quirk and your ass would you marry me ?
Katsuki, sighs: yes I will nerd
Drunk izuku, jumping into his arm : I finally confessed I can’t believe you said yes
Katsuki : ...
Drunk izuku, running away in the street and yelling : hey idiots I'm getting married to kacchan, he will finally be mine and not yours HAHAHA
Ochaco : should we tell him or-
Katsuki : no, we don’t need to, it’s the third time he proposed this month and he forgot that we’re married since 5 years, don’t forget to record round face I want to see his face when I’ll show him the video tomorrow
BakuDeku Pro-hero headcanons:
— Bakugou leave a bento with a small note scolding him for not eating properly.
— Midoriya would sometimes make a detour during his patrol so he could “bump” into Bakugou.
— Bakugou would brag about Midoriya to his sidekicks whenever they see him on the television but would never praise Midoriya face-to-face.
— Midoriya chit-chats with Bakugou’s sidekick when Bakugou is assigned in an out of town mission. They’d talk about Bakugou and would tell Midoriya all the praises Bakugou would sing when he’s not around.
— Bakugou owns low-key Midoriya merch and bought a costume similar to Midoriya’s during valentines to surprise him.
— Midoriya has Bakugou and All Might merch in his office.
— Bakugou would sneak in bouquets of flowers, snacks, and gifts in Midoriya’s office during valentines or white day then pretend to not care about the celebration.
— Midoriya takes photos of Bakugou when he gets to him post-fight. He would make it his wallpaper and Bakugou would make a fuss about it but would leave it be.
— Bakugou has a small photo of Midoriya tucked in a locked drawer in his office so he could look at it when he’s tired.
Katsuki is just as much of a love interest as Ochako
Have you ever noticed how in official art, Deku is in the middle which makes sense since he is the protagonist. Katsuki is next to him probably because he is the deuteragonist and then you would expect Todoroki to be on Deku’s other side since he is the 3rd most important character. But it’s not. It’s usually Ochako on the other side. There’s lots of art like this.
Of course the official art thing could be explained. Maybe it’s just random. But then there are also things like how every time there’s an interaction between Katsuki and Deku, the next interaction Deku will have will be with Ochako, and vice versa. This is evident in chapter 322. Katsuki has the biggest moment in his character arc where he apologizes to Deku.
A chapter or so later, Ochako has her shining moment where she defends Deku from the mob.
When Deku unlocked blackwhip during the joint training arc, he was angry because Monoma insulted Katsuki. Although this wasn’t an interaction with Katsuki, the situation was still related to Katsuki.
After Deku was done talking to the vestiges, the next interaction he has is with Ochako where she helps him calm down.
The first time this pattern was seen was in the 3rd episode. Deku gets to UA for the entrance exam. He is walking and then Katsuki tells him to get out of the way.
Once Katsuki leaves, Deku trips but then is saved by Ochako and they talk for a little bit, or well Ochako does. This pattern has been happening consistently throughout the entire series.
If we analyze Katsuki and Ochako’s characters, it’s pretty obvious they are foils. In the beginning of the story, Katsuki is rude, ambitious, takes his goal seriously, feels threatened by Deku for his determination and heroism, and says he hates him. Ochako is the exact opposite. She is polite, lacks proper determination, doesn’t really take her goal seriously, admires Deku for his determination and heroism, and has a crush on him. Even as the story progresses and they get character development, they are still each other’s foils. Especially when it comes to their relationships with Deku. At the start, Ochako was infatuated with Deku for his ability to save. She would try to be exactly like him and would often use him as her motivation to win or save.
Likewise, Katsuki hated Deku. He felt very threatened to the point of bullying him. He really hated his ability to save. This is all symbolized perfectly well in the Bakugou vs Uraraka fight during the sports festival. Two narrative foils fighting it out. Ochako, who is motivated by her desire to be just like Deku, and Katsuki, who is trying to defeat Deku as best as possible, or in this case, Ochako who wants to be exactly like Deku. This is proven when Katsuki says he knew Ochako would have a plan because she’s always hanging out with Deku.
As the story unravels, Ochako learns to see the bad sides of Deku’s heroism while Katsuki learns to appreciate Deku’s heroism. Ochako comes to this conclusion after she decides to lock her feelings away and when Deku leaves for his vigilante mission.
Katsuki learns this through his atonement arc, during the war as he recalls the good things about one for all, and when he decides to lead the class to find Deku.
Even during all of this, Katsuki and Ochako are still acting like foils. Even up to the apology. Katsuki’s apology is in front of the class but is drawn in a way that show’s only Katsuki and Deku are the focus, it’s soft, and seems very comforting. Ochako’s big moment is in front of the entire crowd, she’s yelling with a megaphone, and is very assertive.
Okay but what does all of this even mean? Well, the main thing that keeps Ochako and Katsuki as foils is their relationship to Deku. Most of their character arc is about this relationship. Ochako was infatuated with Deku to the point it was bad for her journey as a hero and Katsuki bullied Deku which was also bad for his journey as a hero. They both needed to tone it down. Obviously Ochako isn’t gonna start bullying him, but she will lose her crush on him and become a good friend and rival that will help them both grow as heroes. For Katsuki, there are a lot of possibilities for what could happen. Narrative wise, it makes sense for Katsuki to develop a healthy crush on Deku as he grows as a hero. But I don’t think Horikoshi will explicitly state that since this is a shonen series. The story will probably say they are good friends and rivals but if you look for the subtext, you will be able to tell that there is implied romance.
