TodoBaku

TodoBaku is the slash ship between Shoto Todoroki and Katsuki Bakugou from the My Hero Academia fandom.

Canon
Todoroki Shoto is the son of Endeavor, the number 2 hero, while Bakugou Katsuki is the former childhood friend of Midoriya Izuku. They both end up in the same class at UA as first year students and are studying to be pro heroes. They start out as rivals, Katsuki seeing Shoto as one of the people he needs to beat on his path to becoming No. 1 and Shoto who is shown to be never intimidated by Katsuki, unlike pretty much any of their other classmates.

Season 1= In the first team battles, Shoto comments on Katsuki's skill, saying: "He doesn't look like the type to think, but he's more subtle than I expected." He also proceeds to explain what Katsuki did. This is also the first time we've heard Shoto say something. During Shoto's battle, Katsuki is surprised and angry seeing Shoto's effortless win after losing his own battle to Izuku. When he was yelling with tears in his eyes to Izuku, he yells "As I watched the ice guy, I thought: "I can't beat him!". This started off Katsuki and Shoto's mostly one sided rivalry from Katsuki's side and Katsuki starts seeing Shoto as a proper rival.

Shoto and Katsuki only have brief interactions during the U.S.J Incident, together with Izuku and Eijiro they go to help All Might. After the fight with the nomu, Shoto makes a comment to Katsuki about how the whole school wasn't attacked if all the Pro Hero teachers were here.

Just before the Sports Festival begins, when Shoto makes his declaration of war against Izuku, Katsuki (and the rest of the class) is watching them. When the first part of the Sports Festival starts and Shoto starts out with freezing the ground but Katsuki and some others dodge and he declares he won't get him get away that easily. Later when Shoto starts getting really out on front, Katsuki says that he won't let Shoto get ahead of him. When Katsuki finally catches up to Shoto, he says he shouldn't have declared war to the wrong person (Aka he should've been seeing Katsuki as his greatest rival). They continue running while attacking each other and stay in the lead until Izuku cuts in and gets ahead of them. They then stop fighting to catch up to Izuku but lose. During the Calvary battle they don't interact much outside of Katsuki going after him and putting Mina on his team to deal with Shoto's ice. However he does mention Shoto by name, while he usually calls all of his classmates by nickname, most likely because he doesn't care about them enough to remember their names. However Katsuki sees Shoto as a real rival, therefore he remembers his name, the only other classmate he called by his name is Kirishima, who he called by name for the first time in the cavalry battle since he might an impression on him somewhat when joining Katsuki's team (considering he and Izuku are childhood friends it's safe to assume he knows Izuku's name, he just didn't call him by his name).
 * -|Season 2 =

While Shoto is talking about his past to Izuku, it is shown that Katsuki is eavesdropping on them and is surprised at Shoto's past. During Izuku and Shoto's battle, Katsuki is paying a lot of attention and makes his own analysis of Shoto's quirk. After Katsuki and Shoto win the semifinals, Katsuki and Shoto look/glare at each other immediately. Before their battle, Katsuki accidentally walks in Shoto's waiting room and is furious at how Shoto barely bats an eyelash to him and blows up the table, asking him where he's looking at and how's it's no way to treat his opponent in the final. When Shoto immediately starts asking about Izuku it makes Katsuki even more furious. Katsuki asks him who the hell cares about Izuku and Shoto's family drama and his feelings. Katsuki says he doesn't care about any of that and that Shoto should just use his fire against him as well and walks away. Katsuki is excited about the chance to beat Shoto indisputably while Shoto uses his full power.

Their battle starts and Katsuki has the upper hand. When Shoto's father Endeavor yells at him to use his left side, Shoto looks at his father, making Katsuki angry at him being distracted. Shoto doesn't use his fire because of his father. Katsuki tells him to stop screwing around and asks if he isn't strong enough for his fire. Katsuki feels like he's being made a fool out of and tells Shoto he can't get an indisputable first place if Shoto underestimates him. He then says to him: "There's no point if I can't get higher than Deku (Izuku). If you have no intention of winning then don't stand before me! Why the hell are you just standing there, dammit!" After Izuku encourages Shoto, Shoto starts emitting flames and Katsuki gets excited. Katsuki thinks that Shoto should only focus on him when he's standing in front of him. Katsuki starts his final attack and Shoto mentally apologizes to Katsuki, meaning Shoto does recognize Katsuki's feelings as valid and feels bad. Just before Katsuki does his final attack, Howitzer Impact, Shoto thinks about his past again and stops emitting flames and just takes Katsuki's attack. After the smoke settles, it becomes clear that Shoto got blown out of bounds and is unconscious. Katsuki is declared the winner, but Katsuki is furious when he realizes Shoto didn't use his flames. He runs up to Shoto, grabbing him by the collar and yelling at him with an angry but despaired voice: "Hey, stop screwing around! Didn't I tell you there was no point, dammit? To get first place like this! Like this? Like..." Katsuki then passes out next to Shoto due to Midnight's quirk.

During the award ceremony Katsuki had to be restrained on stage and refused to accept the victory because he didn't win from Shoto's full power. Katsuki most likely felt like Shoto didn't see him as a proper rival, while Katsuki did see Shoto as a strong rival and the most skilled in class next to him. While Katsuki was frustrated at first seeing Shoto's skill, Shoto wasn't focused on him even during the fight and was focused on Izuku (who he already felt somewhat both inferior and superior to) and his father. In Katsuki's eyes, Shoto saw Izuku as more of a rival than Katsuki, most likely feeding more into Katsuki's sense of inferiority to Izuku.

In the first episode of season 3, when during the swimming competition, Katsuki, Shoto and Izuku are to 'swim' the finals, Katsuki suddenly starts saying Shoto should better not hold back against him like at the Sports Festival and he should come at him seriously. Shoto tells him he will. Afterwards when Katsuki and Eijiro walk home together, Katsuki is angry at Aizawa for stopping the race just before the finals and Eijiro says he gets it but he should calm down and says "Midoriya and Todoroki are classmates- and friends right?" Katsuki tells him to shut up, but doesn't deny it and instead says it doesn't matter who it is, he needs to beat them regardless.
 * -|Season 3 =

When the entire class is going through the Beast Forest, Katsuki and Shoto take out an earth beast together, afterwards they run side by side and Katsuki tells him not to get in his way, while Shoto tells him he's not in his way. After Katsuki calls Kota a 'precocious brat', Shoto makes a comment about how he's kind of like Katsuki. Katsuki says: "What? Not at all! Anyway, shut up, you GG bastard!" Shoto apologizes with a deadpan face. When the test of courage starts, Katsuki and Shoto are paired together, much to Katsuki's reluctance who immediately demands a new partner. They do part of the test of courage together before the attack, a scene shown where Katsuki and Shoto simultaneously let out an 'Oh' because of Yui who pops out of the ground.

When the LOV attack during the test of courage, Katsuki and Shoto are still together with Shoto carrying a person from 1-B on his back. Shoto says what they should do, although Katsuki starts saying he shouldn't tell him what to do (although but less bite) they get interrupted by Moonfish with Shoji's cut off hand. Katsuki asks Shoto who was in front of them, Shoto says it was Shouji and Tokoyami. When they get notified Katsuki is the target of the LOV, Katsuki ignores the warning not to act alone and rushes towards Moonfish. Shoto manages to save Katsuki by stopping Moonfish's blades from impaling him with his ice. Shoto tells him not to rush into things. Katsuki ignores this and rushes in again but Shoto saves him with his ice again. When Katsuki starts letting off small explosions, Shoto tells him if the trees catch fire and it spreads they'll be surrounded and die. Katsuki yells at him that he knows that. Moonfish continues the assault and Shoto's ice is the only thing stopping him. Katsuki tells Shoto to just cover the fire with his ice but Shoto says it's dangerous since the explosion will impair his vision as well. The fight gets interrupted by Shoji, Izuku, Tokoyami and an out of control Dark Shadow. Katsuki stops Shoto from stopping Dark Shadow before Moonfish is dealt with. After Moonfish got taken out, Shoto and Katsuki stop Dark Shadow together. When starting to escort Katsuki to safety, Shoto tells Katsuki to walk in the middle, although Katsuki yells at him not to protect him. Shoto then tells Katsuki to make sure he keeps up and Katsuki tells him not to tell him what to do.

When Katsuki and Tokoyami get taken my Mr. Compress, Shoto tries to stop him with his ice. Shoto, Izuku, and Shoji go after Mr. Compress and fight the villains. When the orbs containing Katsuki and Tokoyami fall out of Mr. Compress' mouth, Shoto lunges for Katsuki's one, but it got taken away just before he reached it by Dabi. Shoto, Izuku, Tokoyami and Shoji watch as Katsuki gets takes away by the villains.

When the class visits Izuku in the hospital, Shoto is the one bringing up the fact that Katsuki isn't with them. Eijiro brings up the plan to save Katsuki, saying that Shoto and him were at the hospital yesterday because they couldn't stay at home and they decided to go save Katsuki together. They invite Izuku and tell the class their plan. Together with Momo and Iida, the 5 of them go to what is possibly Katsuki's location. In the train, Shoto reminds them that what they're doing is selfish and they can still turn back. When they arrive at the location and All Might and Katsuki are in a pinch, Izuku comes up with a plan to get Katsuki away and Shoto creates a giant ice ramp so the others can get Katsuki out. When Katsuki's out, Shoto escapes with Momo. After watching All Might's fight, they bring Katsuki to the police station.

When Katsuki gave Eijiro money for the night scopes he bought, instead of being distracted by Denki, Shoto was the only one of the class looking at Katsuki (minus Eijiro). During the provisional license exam arc, Katsuki and Shoto don't really interact, however, they are the only ones in class 1-A to fail the license exam and are going to take extra classes to get their provisional licenses. However in episode 20 of the third season they do interact. They're together in a class with Ochako, Izuku, Iida and Asui. They have to catch a hypothetical villain. When Katsuki says that one of the hostages killed the villain, Shoto asks him for the motive, to which Katsuki yells in his face that it's obviously the jewelry. Tsuyu points out that it's too reckless and Shoto says the villain was holding the jewelry, angering Katsuki. Shoto is also one of the people that stopped Katsuki when he was going to get violent. After Izuku and Katsuki's fight they have house arrest, so Shoto asks what Katsuki is going to do about it. Katsuki tells him to shut up and that it's none of his business.

In the fourth season, Shoto and Katsuki are shown to go to the extra classes together for the provisional license. In episode 2 of season 4, Shoto says Katsuki's lucky that after his fight with Izuku he can still take the extra classes and that they need to catch up as soon as possible, Katsuki says he needs to shut up and walk behind him. Later when talking in the common room about the work studies and that Izuku got accepted, Shoto and Katsuki are standing together away from the others and Shoto makes another comment about how they need to catch up as soon as possible. Katsuki makes an annoyed sound in response. When hearing Tokoyami is going to do a work study with Hawks, Shoto says they need to catch up as soon as possible again. Katsuki yells at him to stop saying that. When Shoto is going to say it once more, Katsuki yells in his face to shut up. Shoto remains unfazed. Later Shoto and Katsuki come to class with injuries from their extra classes. When Denki and Mina talk about the classes, Katsuki yells at them to not talk like they're not there.
 * -|Season 4 =

On the night the work study students returned, Shoto and Katsuki both go to bed early for their extra classes. The next day they go to the extra classes, Katsuki tells Shoto to walk behind him and then Shoto says he feels bad about making Aizawa take them after yesterday, to that Katsuki says he isn't going to make small talk with Shoto. Together they go to the extra classes. They run into the Shiketsu students in the building. After they got dressed, Katsuki sees Inasa and Shoto talking, with Inasa trying to befriend Shoto and he says that makes him feel sick. When Endeavor yells encouragement to Shoto, interrupting their class, Katsuki looks towards Shoto, who's turned away from Endeavor. During class, Gang Orca pulls apart Shoto, Katsuki, Inasa and Camie) for a special trial.

Later when Katsuki says a little violence is necessary for kids, Shoto says that isn't true, to which Katsuki responds that's how he was raised. Shoto responds that there should be a better way, Katsuki remembers Shoto's past (only shown in manga) and says he should show him his way of doing things then. When the kids attack and Camie makes an illusion of Shoto who says with a smile: "Hey, there. I want to see your cute face. Don't spoil it with wrinkles." Katsuki bursts out in a fit of genuine laughter for the first time at this and says: "I thought it was good! Glamouroki!" Shoto asks if it was really that funny. After Shoto and Inasa make a giant ice slide, Katsuki looks at Shoto who's surrounded by the excited children. Also when Katsuki calls out to Inasa and Shoto, he calls Shoto 'Todoroki', while he usually calls him by a nickname. Later when they're outside preparing to go home and Endeavor starts talking to Shoto, Katsuki looks at them and in the manga Katsuki looks back at Shoto after his talk with his father.

During the second half of season 4, Katsuki and Shoto's interactions are minimal. However when Katsuki starts protesting about the class providing stress relief for the other students, Shoto tells Katsuki not to protest when he didn't even participate in the discussion. After Katsuki explains his reasoning and says: "Let's kill UA with our sound!" Shoto and Iida realize that Katsuki has been carrying a heavy burden since he got kidnapped.

During the Joint Training arc, Shoto and Katsuki don't interact much, outside of a bit of commentary. After the matches with class 1-B, Katsuki overhears Izuku and Shoto talk about Black Whip and Shoto figured out it was a second quirk, however Izuku denies this and Shoto believes him. Katsuki then thinks: "You're sharp and dull at the same time, huh, Half-and-half bastard?".
 * -|Season 5 =

A different day it was shown that Shoto and Katsuki are doing the exam so they can get their provisional licenses. On the way back after getting their licenses, they encounter a group of villains stealing bags from civilians. They immediately decide to stop the villains themselves. All Might comments on the fact they've only got their licenses for 30 minutes, so Katsuki asks: "Then how many minutes do we have to wait until we're heroes?". Together they stop the villains in their tracks, working well together and not once getting in each other's way. They know each other's strengths and their own and manage to stop the villains without anyone getting injuries and not damaging buildings even though they have destructive quirks. They never tried to be better than the other. After defeating the villains, Katsuki notices the move that Shoto used to take out the leader was the same one as he used at the Sports Festival. Shoto confirms this and asks if he is injured. Katsuki denies this angrily and Shoto asks about the woman who didn't evacuate and Katsuki denies this as well. Both of them get pat on the head by All Might. Afterwards Shoto still has to melt the ice and Katsuki says he won't help. When they get home they get congratulated by the entire class.

Katsuki and Shoto get interviewed later and the interviewer comments on how they work together. Katsuki denies they work well together, while Shoto says they're friends. Katsuki says he shouldn't spout random bullshit and asks since when the hell the were friends. Shoto says they spent a lot of time together because of the extra classes. Katsuki says that the amount of time they spent together has nothing to do with being friends. However this means that Shoto considers Katsuki a friend even if Katsuki doesn't and has no ill will against him. When the interview gets out, Katsuki has both his face and his answers edited out. Later Shoto apologizes for being the reason why Katsuki is edited out, but Katsuki tells him to not be so cocky and that he holds no influence over him. Shoto responds with a deadpan 'I see'. After the interview practice, Shoto and Izuku are talking and Katsuki looks at them.

While cleaning up after the Christmas party, Shoto invites Izuku and Katsuki to go with him for the work studies to his father. They both accept. When they meet up with Endeavor for the work study, Endeavor says he had wished Shoto came alone, Shoto says he shouldn't complain when he already accepted. Katsuki says to Endeavor: "I've been thinking this since the extra classes, but you're a real stick-in-the-mud, aren't you?(manga)/but you're kind of cringy(anime)." Endeavor asks if Shoto's really friends with this brat (Katsuki). Katsuki says that it's fine as long as he's able to see the No. 1 work. Endeavor yells at Shoto that he told him to bring his friends. When they arrive at the agency and Burnin' says that Izuku and Katsuki will most likely end up working with the sidekicks since Endeavor only wants to train Shoto. Katsuki is angry and says he only came here so he could watch how the No. 1 works. Izuku tells him to calm down, but Shoto says that's indeed not what he expected and he'll talk to him about it. Endeavor interrupts and says he'll train all 3 of them. Izuku and Katsuki watch as Shoto tells Endeavor why he came and that he should stop trying to act like a father in front of his friends. This also means regardless of what Katsuki says, he considers him a friend.

During the work study and seeing Endeavor work in person, Shoto asks Katsuki if he noticed. Katsuki says that there's nothing that Shoto could realize that Katsuki can't with an irritated smile and tells him to spit it out. Shoto talks about Endeavor's Jet Burn and using his flames to propel himself. Katsuki says it's a rip-off from his Explosion and asks him if he just realized it. Shoto smiles and says: "Yeah, I took the long road. (anime)/Yeah I suppose you could call it a rip-off. (manga)" Shoto and Katsuki get the same assignment from Endeavor and Katsuki asks why he's always paired up with Shoto. When eating something on the roof of a building, Shoto and Katsuki are seen eating the same thing. The 3 of them sleep at the agency and at one morning, Shoto says that they were close to surpassing Endeavor's speed yesterday and that today they would surpass him. In the anime Katsuki says that he was the only once close and that Shoto was too slow, which meant he was better than him. Shoto (and Izuku) ignores this and Katsuki yells at them not to ignore him. In the manga, Katsuki says that the both of them are slower than him, making him better to which Shoto responds: "Yeah, I'm still not used to focusing my flames."

Later, Izuku and Katsuki are invited to dinner at the Todoroki house. Katsuki demands why to which Shoto responds his sister invited everyone for dinner, Katsuki demands why again and Shoto says it's because she wanted to meet his friends. Katsuki yells at him to tell her that they've never been friends. During the dinner tensions between Shouto's brother Natsuo and Endeavor rise causing Natsuo to leave early. When cleaning up, Izuku asks if Katsuki also knew about the Todoroki family drama, Katsuki says that they were the ones talking about it right in front of them. Katsuki also yells that Shouto and his sister shouldn't talk about their drama when they have guests over and Katsuki listens while Shouto's sister explains why Natsuo still is so aggressive towards Endeavor. When they leave, Katsuki says to Shouto's sister to teach him her mapo tofu recipe, Shoto says she can just text it to him and he'll text it to Katsuki. Later when Ending attacks, Shoto, Katsuki and Izuku work together to save Natsuo and civilians and take out Ending with flawless teamwork, surpassing Endeavor.

Katsuki was the one to save Natsuo and gets caught up in Endeavor's hug while helping Natsuo. After escaping, Katsuki turns to Shoto and asks what happened to Ending. Shoto confirms that he has been captured. When Katsuki revealed that his hero name isn't Bakugou, Izuku asks what it is. Katsuki yells that he'll never tell him and to drop dead. Shoto asks if he would tell him, to which he yells that he can forget it and he can drop dead as well. In the final episode, Katsuki asks who cut the chives, Shoto says he did it and Katsuki says his sister would cry if she saw it. When Katsuki does the cutting himself, Shoto comments that he's good at it, which Katsuki responds to by saying he's just bad at it.

Before the mission to defeat the Paranormal Liberation Front, half of class 1-A is waiting for the signal to start the mission at the rear guard for logistical support. Katsuki complains about being at the back as support and wants them to let him be at the front, catching Shoto's attention. Shoto explains that they only have provisional licenses, which makes Katsuki turn to look at him and he yells at him to shut up. Later, when Izuku and Katsuki are with Endeavor, Aizawa, Rock Lock, Manuel and Gran Torino, Shoto also shows up and was revealed to have followed them but was helping out with fighting the Nomus. Shoto treats the wounded while Izuku fights Tomura. Katsuki realizes Izuku will lose if the fight goes on and he asks Shoto if he's done treating the wounded. He confirms he is and asks why he asked that. Katsuki tells him to shut up and hold onto him. Shoto is surprised at first but quickly does as told. Katsuki instructs him on what to do and the 2 of them fly up to Tomura with Endeavor. Throughout the exchange, Katsuki calls Shoto repeatedly by his name, instead of a nickname. When Endeavor gets pierced by Tomura's tendrils, they both shout out his name in horror. After Katsuki got pierced by Tomura's tendrils, Shoto fishes Katsuki out of the air, Endeavor as well, saving them from falling. He holds the 3 of them in the air as he watches Izuku and Tomura's exchange, Katsuki's arm around his shoulder despite having grabbed his leg when saving him and holding Endeavor wrist. After grabbing Izuku as well, Shoto puts the 3 of them on the ground, he checks on them, starting with Katsuki. In the anime, Shoto confirms to Izuku that Katsuki is alive.
 * -|Season 6 =

After waking up in the hospital, Katsuki asks how everyone is, starting with Izuku and Shoto.

After Izuku left Katsuki and Shoto lead the class to confront Endeavor about Izuku's whereabouts. When Shoto starts getting angrier at Endeavor, Katsuki cuts in and places his hand on Shoto's shoulder, either to calm him down or a way of saying he got it from here. However either way is something that is extremely rare coming from Katsuki, because he doesn't tend to initiate positive physical contact. He's been seen accepting it, however initiating it, is not something he really does especially with his classmates. When the class finally finds Izuku, Katsuki, Shoto and Momo use a combo to take out the villain Dictator. Later they are seen standing back to back, and Shoto uses Flashfreeze Heatwave to propel Katsuki and Iida.
 * -|Manga =

After hearing that Shiketsu has something similar to the UA barrier, Katsuki and Shoto look at each other and simultaneously say: "They did say that..."

In chapter 327, after Eijiro asks Shoto if he's not frustrated, Katsuki is looking at Shoto behind Kirishima as the only other one in the panel, which is another instance of Katsuki looking at him when he's talking about his past. These instances show that Katsuki is interested about what Shoto's mental state is and can also be seen as Katsuki caring/looking out for Shoto.

Later, after class 1-A moves to the stronghold Troy, Shoto, Iida, Eijiro and Katsuki are in Shoto's temporary room. With Eijiro sitting upright on his bed and Katsuki comfortably laying on Shoto's bed. Shoto apologizes for worrying them but assures he's fine now. After Iida makes a comment on them being similar, Shoto comments that he can't compare himself to Iida since Shoto doesn't even know what Touya likes. Katsuki then speaks up and says that he'd bet he likes udon. Shoto laughs at this and says if that's the case, he wouldn't mind sharing some udon with him. This is yet another instance of Katsuki seemingly expressing concern for Shoto and Shoto's mood seems to be lifted somewhat after Katsuki's comment.

During Shoto's fight against Touya, he has flashbacks from before the fight but after Izuku came back. While Shoto explains his new move to Izuku who missed everything and both him and Denki are fascinated by the cold fire and Shoto explains something he said before, Katsuki suddenly pipes up that he shouldn't forget he's the strongest and calls him a loser. While Shoto thinks back on how the class was always there beside him, Katsuki is one of the people in the foreground. And when he gets flashbacks of the class while he thinks of how they were there for him, Katsuki is also shown twice.

After hearing Shoto defeated Touya, Katsuki grins and says: "Of course he won... that Todoroki..." This shows he has complete faith in Shoto's skill and mental strength, as defeating his own brother took a lot of both, even when others worried. Also not everyone was shown of class 1-A, like Izuku, Momo, Denki and Tokoyami, but Katsuki was and was also the only one at the UA location. It also marks one of the few times Katsuki called Shoto by his name.

Shoto and Katsuki's relationship has grown a lot since the beginning, going from rivalry and dislike to friends who trust each other and work well together. They have shown multiple times that they work well together and trust each other to follow each other's plans without complaint. They trust in each other's strength and although Katsuki had denied it, it is clear that they've become friends. Katsuki is also shown to be always present and watching over Shoto when it comes to his family issues.

Movies
Two Heroes= In the movie which takes place between the Final Exams and the Forest Training Camp arcs, Shoto and Katsuki first interact when Katsuki is yelling at Izuku for having a time close to his after doing an attraction on island where you have to destroy the villains as fast as possible but they get interrupted by Shoto who gets a time even faster than Katsuki's. Katsuki goes to him and yells at his face: "Appearing suddenly trying to make everyone think you're amazing, you bastard?!" Shoto asks if the others are also on the island, Katsuki yells at him not to ignore him and asks why he's here anyway. Shoto says he's here to represent his father. The lady who works at the attraction tells him people are waiting for their try, Katsuki yells at her.

Later when villains attack Eijiro (and Katsuki), Shoto interrupts and saves them. Shoto gets the others away while he, Katsuki and Eijiro fight the 2 villains. However Eijiro gets taken out at the beginning of the fight and Shoto and Katsuki are left to take on the villains. When asked who they are, they both respond they won't tell them. They both take on one villain and don't get in the way of each other. Katsuki eventually takes out one, so the other villain attacks Katsuki but gets Katsuki's explosive sweat on his palms, which Shoto explodes with his fire. In the fight they work somewhat together and don't get in each other's way at all. After the fight Eijiro seems to be unharmed and the 3 of them take on the robots.

When Ochako nearly gets attacked by the robots, Shoto, Katsuki and Eijiro interrupt. Shoto says they'll stop the robots right here, Katsuki says to not tell him what to do. Eijiro says that they make a good combination though, which Katsuki denies. When Melissa and Izuku nearly get blown away, Shoto says to Katsuki to make the propeller face Melissa and Izuku, Katsuki says that he said not to tell him what to do, but he does it regardless, which ends up saving them. Later when All Might is in a pinch, the other classmates arrive and Shoto and Katsuki end up saving All Might. When All Might and Izuku attack the villain together, Shoto and Katsuki end up yelling together: "Get him!" When the villains gets defeated, Shoto catches Katsuki smiling and is smiling himself. When Katsuki catches him staring he looks away with a scowl.

World Heroes' Mission has a prequel manga called: My Hero Academia Special Spin-off: Endeavor’s Mission. In this prequel, Shoto and Katsuki don't interact much by themselves although they work together to face Endeavor with Izuku. In one panel they are seen to be admiring the special suits together and when they're designing their stealth suits, Shoto thinks about how detailed Katsuki's gauntlet designs are.

In the special booklet given to the ones who watched the movie first in theaters, there is a 9 pages long manga short where Endeavor, Shoto, Katsuki and Izuku are at the airport preparing to board the airplane. This has also been adapted into a 5-minute long OVA. In the OVA, it is shown that Katsuki starts listening in the conversation Shoto and Izuku have after Shoto starts explaining that the way Izuku is trying to calm himself down is said to not work when he doesn't swallow it. When Katsuki appears to be nervous, Izuku is surprised while Shoto assures him he'll be fine if he can speak English, Katsuki tells them to shut up. After Shoto says that he wants to sit next next to Izuku and Katsuki instead of his father, Katsuki asks if he still thinks that the 2 of them are friends. Endeavor responds to Shoto but he demands to sit next to his friends and Katsuki yells that they're not friends and if Shoto wants to enjoy the plane ride strapped to the tail of the plane. In the OVA, Shoto tries to grab Endeavor's ticket and then Katsuki gets close to Shoto's face and tells him not to ignore him, Shoto proceeds to ask Katsuki to switch with him and Katsuki yells at him to stop acting so nice. Katsuki grabs Shoto's tie and continues pulling it, but Shoto ignores Katsuki's complaints about not being friends, treats and tie-pulling in favor of arguing with Endeavor. In the OVA, when Katsuki grabs Shoto's tie, Endeavor yells and asks what Katsuki is doing to Shoto. Their arguing gets interrupted by Hawks.

We first see the 2 interact at the beginning of the movie, when the heroes are moving towards the headquarters of Humarize, Shoto reminds Katsuki and Izuku what their jobs are and to not let their guards down. Katsuki asks him who he thinks he's talking to. Shoto and Katsuki take the lead together and Shoto reminds him to not be too rough since most of the members are quirkless, but Katsuki tells him he already knows. The 2 then work together, Katsuki stops the enemies in their tracks and Shoto then freezes them. They continue to move forward together. After the mission fails, Shoto, Katsuki and Izuku are carrying groceries for the team and Katsuki angrily asks why they have to run errands. Shoto explains that it's because they're the lowest ranking members, making Katsuki turn to him angrily, Shoto further explains that they are only on the mission because they're interning with Endeavor. When Katsuki and Shoto are back at the hotel with Endeavor after stopping robbers, while Midoriya is busy with Rody, they are berated by Endeavor for going after a petty crime when they're in the middle of an extremely important mission.

Katsuki tells him not to order him around and they leave.

In the train to Izuku's location, Katsuki asks Shoto if the cases got switched. Shoto confirms and says they're must've been some kind of mix up and Izuku is carrying the case which has something to do with Humarize. Katsuki says that it must be the reason the police is chasing him. Shoto says it's likely and that he guesses that whatever Izuku is carrying, is very important, since the police would not operate on such a large scale if it wasn't. Katsuki says that Humarize has infiltrated the police force, Shoto agrees and says that they have to be careful. Katsuki says tells him not to order him around.

While Shoto and the frozen villain are talking, they get attacked by the 2nd villain again and Shoto tells Katsuki to get her. Katsuki tells him not to give him orders, but starts doing what Shoto told him to. After learning about Flect Turn's plan to take down the top heroes and knowing they won't retreat no matter what, Shoto says they'll use the key themselves to disarm the bombs.

In the dub, after Katsuki tells Rody that extras like him should stay out of the way, Shoto tells Rody he has a point. While Shoto and Izuku move further in the Humarize base, Shoto says they'll leave the rest of the Humarize members at the entrance to Katsuki. Katsuki yells at him to not give him orders.

When Shoto asks why Katsuki stayed behind, he says he didn't want to owe him a debt, Shoto says he doesn't care about that and they should get out of there.

Katsuki calls him a pervert and the villain prepares to make his next move. Izuku intervenes. Izuku also gets caught in the villain's quirk which he explains as 'Endure' which causes you to be unable to move when you put up with him. Katsuki suddenly says that he can move and Shoto agrees. The villain is surprised and Shoto says that they stopped putting up with the villain. Katsuki says that he's just as stupid as his brother and Shoto says he talked too much about his own quirk. The villain asks why they're approaching him, Katsuki says it's because he can't stand him anymore and Shoto agrees. The villain asks if they're going to hurt an ordinary citizen and Katsuki says that's bullshit and Shoto says he's a villain. Then the villain asks if they're going to beat him and Shoto says that it's a yes. Izuku tells them to calm down but Shoto says they can't do that and Katsuki says you'll be caught in his quirk then.

Izuku later explains that after Shoto and him explained, they forgave Katsuki for using his quirk.
