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

Canon
Katsuki and Shoto 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 never shown to be intimidated by Katsuki. In the first team battles, 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 time to deal with Shoto's ice.

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 accidently 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 begins talking about Izuku 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 indesputably 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 undisputable 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. 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 unconsious. 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.

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 reclutance 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 simulataniously 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 one of Shouji'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. 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 trian, 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 provinsional 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 provinsional 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 a Season 2 CD Drama, Bakugou and Todoroki run into each other, while the rest of the class goes to a mall as a group (where Deku runs into Shigaraki). While they are having their usual banter, a stranger walks up to them and asks them if they are from U.A. The two start to realize that the stranger is, in fact, a villain. Todoroki attempts to get both of them away from the villain, but they both learn that the villain has a quirk that can make someone, when targeted, stick to anything they touch for as long as the quirk is activated. The villain puts the two in awkward positions and takes pictures of them that he says he will upload to the internet. While Bakugou continues to struggle, Todoroki remains calm. Later on todoroki thinks of a plan and plays along to the villains game bakugou picks up on it and once the villain was distracted they head butted him to have the villain to release them from his quirk and run off.

In the fourth season, Shoto and Katsuki are shown to go to the extra classes together for the provinsional 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.

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 and Inasa (+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 laughing 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.

In Chapter 241, Bakugou and Todoroki are interviewed about their fight with villains after getting their Provisional Hero Licenses. When asked if they are friends, Bakugou is quick to deny; Todoroki states that he considers him and Bakugou to be good friends.

We also see that Bakugou and Todoroki have a newfound respect for one another as they can work together in unison, combining their quirks.
