Entrance Exam Arc
Izuku was fanboying over Present Mic when he explains the rules of the Entrance Exam, muttering about he listens to Present Mic’s radio every week, he’s so moved and very amazed that every UA Teachers are Pro-Heroes, and then Katsuki told him to ‘shut-up’. After Present Mic explains about the rules, Tenya asks a question, talks about how shameful if UA did a misprint and then points his finger at Izuku, scolding him for muttering, telling him it’s distracting and then telling him that if he’s there just for a pleasure trip, he better go home.

Before the exam begins, Izuku spotted Ochako near the gate, so Izuku thinks on approaching her to thank her for helping him when he’s falling before. But when he’s still walking, Tenya puts his hand on Izuku’s shoulder to stop Izuku and telling him that Ochako appears to be trying to focus. And then he asks Izuku about what he is doing there and thinking that Izuku is taking the Entrance Exam to interfere with everyone else which Izuku quickly told him that it’s not like that.

After Present Mic says ‘Start’ to start the exam, they’re all stopped for a second and after Present Mic told them that heroes doesn’t need countdown so go run, Tenya and the other Examinees quickly run into the gate leaving Izuku and then Izuku run trying to catch up with them. After his One-Pointer Robot got ‘stolen’ by Yuga and Present Mic announced that the exam will end in 6 Minutes and 2 Seconds, Izuku search for Pointer Robots, where he see Tenya kicking a Two-Pointer Robot while shouting “45 Points!” and Izuku repeated his words in surprise.

After the Zero-Pointer Robot is released, Izuku freeze on his place, Tenya can be seen running past him while looking at him but the quickly looks away. After Izuku saves Ochako from the Zero-Pointer Robot, Tenya along with the other examinees stare at him with a very amazed or rather surprised expression.

Quirk Apprehension Test Arc
When Izuku is going to enter his class; 1-A, he hopes that he won’t be in the same class as Katsuki and Tenya, but when he opens the door, he ended up seeing Tenya scolding Katsuki for putting his legs on the desk and saying it’s disrespectful to the heroes who once sat on that desk, the upperclassmen’s who once sat on that desk, and the desk maker. Katsuki asks Tenya “What junior high did you go to, you side character?”. Izuku’s face immediately changes into a ‘God please have a mercy on me’ expression while pitying himself with the fact that the Top 2 of students he doesn’t want to be in the same class is the first sight he sees after he enters the class.

And then Tenya introduces himself as Tenya Iida from Soumei Private Academy, and after some convo, Katsuki and Tenya notices Izuku standing on the class entrance, Tenya looks incredibly surprised, saying “You’re…” making the entire class looks at Izuku. and while Izuku awkwardly stuttering, trying to form a sentence, Tenya approaches saying, “Good Morning” to Izuku and then trying to introduce himself where Izuku cuts him by saying “I heard!”. Tenya stops on his track, Izuku calms down for a second and then introduce himself and replies by saying; “Nice to meet you, Iida”.

Iida changes his gesture from his signature chopping air gesture to standing while putting both his arms straight beside his torso, asking that if Izuku realizes ‘there’s something more than that practical exam’, Izuku’s face turns into a confused expression and Tenya continues his talking, saying that he have no idea, confessed that he has misjudged Izuku and admitting that he hate to admit but he thinks Izuku is better than him and Izuku mutters “Sorry, actually I didn’t realize anything” and after that Ochako appears and Tenya just standing there watching the two having a conversation. When it’s Izuku’s turn on the Pitch Ball, Tenya commented that it doesn’t look good for Izuku if he continues like this, and when Katsuki replies by saying Izuku is Quirkless, Tenya gasps in surprise and replies; “Quirkless?! Are you not aware of that he did in the entrance exam?”. After Eraserhead talks to Izuku and giving him back his quirk after erasing it, Tenya observed and saying that it looks like he received some advice, whereas Katsuki replies by stating the probability of Eraserhead just telling Izuku that he's expelled.

After Izuku tries to do the Pitch Ball again using his quirk, Tenya and the other’s face turned surprised. Tenya notices his finger are swollen and saying it with a concerned voice. He also noticed that the same thing happens on the Entrance Exam and thinking he has a strange quirk. When Katsuki makes an explosion and run at Izuku angrily thinking Izuku has been lying to him by hiding his quirk, Tenya, along with Ochako and Yuga makes a surprised gasp. When Eraserhead says that he’s lying about the whole expulsion thing, Tenya, Izuku and Ochako together makes a surprised scream while saying “What?!”.

After the test ended, Izuku is walking to the gate to go home tiredly, and then Tenya puts his hand on Izuku’s shoulder, stopping him on his track. Izuku turns his head and saying his name surprisedly. Tenya asks Izuku about his finger, “Is your finger healed?” he asks. “Yeah! Thanks to Recovery Girl” Izuku replies. And then they decided to walk together, Tenya starts by telling Izuku that he was really taken in by Eraserhead, thought that ‘This is the best of the best’ and such, that he didn’t think a teacher would encourage them with a lie. And while Tenya is talking, Izuku thinks to himself that he thought Tenya was scary, but he’s just earnest.

And after Ochako saying that she thought Izuku’s name were ‘Deku Midoriya’, Izuku explains that his real name is Izuku and Deku is just a nickname that Katsuki gave to Izuku as an insult, Tenya mutters “An insult, huh?”. And after Ochako apologizes and saying that it’s sounds like ‘Dekiru (You can do it!)’ and Ochako love how it sounds, Izuku quickly says that “I’m Deku!” Which Tenya disagree, saying that he’s accepting it too easily, “Wasn’t that an insult?” he continues. And that how their friendship with Ochako began.

Tenya Iida: President of Class 1-A
After the class decided to take Tenya’s suggestion on using voting to pick the leader, Tenya ended up in 0 Votes because he choose to vote Izuku rather than to vote himself. At lunch, Izuku told Tenya and Ochako that he feels like even though he’ve been chosen as the class rep, he didn’t know if he qualified for it or not. Ochako replies by saying he is qualified, and Tenya assure Izuku that it’ll be fine.

Turns out, Tenya is the one who voted for him along with Ochako. Even though he want to be the class rep, he trusted Izuku more to become the class rep, thinking Izuku is more suitable and confessed that he merely did what he judged to be correct. Ochako and Izuku immediately notices that Tenya is a rich person, when Ochako asks if he is a rich person, Tenya immediately changes his expression into a kind of unhappy one, telling them that he tries to change how he talk because he didn’t want to be called that and sighed when Ochako and Izuku stares at him awkwardly.

Tenya tells them about his family has been heroes for generations, and he’s the second son. Izuku and Ochako let out an amazed ‘What?! Wow!’, and then Tenya mention about Tensei Iida, or also known as; The Turbo Hero, Ingenium. He asks them if they know about him, and Izuku excitedly says that he does know about him, telling all the information he know about Ingenium. And his expression quickly changes after he realizes something; Tenya straight out telling them that Tensei is his elder brother and Izuku screams “That’s amazing!”.

Tenya tells them that Tensei is a likeable hero who honors the rules and leads people, that he set his sights on being a hero because he want to be just like Tensei. However, he think that it’s still too sun for him to lead others. Because he thinks that, unlike him. Izuku realized the point of the practical portion of the entrance exam, so he thinks that Izuku is more suitable for that job. After Ochako points out that it’s the first time that she see Tenya smiles, Izuku realizes that Ingenium is to Tenya what All Might is to him.

Suddenly, a bell rang and announcing that there’s someone trespassing on school grounds. Izuku, Tenya and Ochako quickly run to the emergency exit, but due to the crowded hallways and panicked students, Izuku got separated far from Tenya and Ochako. Tenya got very close to the point his cheek got pressed on the window and he finds out that the press is the ones who trespass, so he tries to calm everyone down but ended up being pushed even further to the window and got separated from Ochako. Tenya tries to approach Ochako while thinking of what Izuku or his brother would do in this situation. After he got floated by Ochako’s quirk, he use his ‘Engine boost’ to go over the emergency exit door, on the way, Izuku shouts Tenya’s name in worry. Tenya hits the wall in the emergency exit sign people pose and told everyone to calm down and then announcing that it’s just the press that trespassing, Izuku stares at Tenya amazed and then smiles with a sparkle in his eyes.

After all of that, Izuku confessed to the whole class that he thinks that Tenya should be the class rep after all, saying that he was able to get everyone’s attention in such a cool way, and he think it would be the best for Tenya to do it. And Tenya stares at Izuku in disbelief, quickly looking at Eijiro who adds that it’s true that Tenya was a big help at the cafetaria today and Denki replies by agreeing and say that he kind of looked like the person on the emergency exit signs.

Excursion to the USJ
When Tenya blow his whistle and calling the whole class to gather round, telling them to form two lines by their student numbers in order to make bourding the bus go smoothly, Izuku commented about Tenya to Ochako that he thinks that Tenya is going at full throttle, but the bus ended up to be the type that Tenya didn’t thought gonna be.

After Tomura bring a huge amount of villains into USJ, and Eraserhead attacks him, the students except Izuku quickly evacuate to the exit door, Izuku observes Eraserhead until Tenya turns his back and call out Izuku telling him there’s no time in analysing things and commands him to hurry up and take a shelter.

Before the Sport Festival
The whole class is very excited about the sport festival, talking about standouts. Izuku is very amazed and commenting that everyone’s so into it. Tenya replies by asking “You’re not?”, and then stands up (He was sitting on his chair) reminding Izuku that they have enrolled there to become heroes, so of course they would get fired up. After Tsuyu commented that Tenya got a unique way of getting fired up, Tenya repeat his ask again does he feel the same, Izuku replies that of course he do.

After Tenya and Izuku got into some conversation with Ochako about why she wants to become a hero, All Might appears and asking Izuku to get lunch with him, where Izuku glances at Tenya to ask for his approval. And after Tenya nods, Izuku quickly run at All Might to have lunch with him. Ochako and Tenya is in a line to get lunch when Ochako blurted out that she wonder what All Might wanted with Izuku, and then Tenya replies by telling her that “I heard that when All Might was attacked by villains during the USJ incident, he rushed out alone to help, so it’s perhaps about that. Or the boundless power they both have are similar too, so maybe All Might has taken a liking to him.”, and then he palms his fist, changes his expression into an admiring expression while saying that Izuku is amazing.

On the Sport Festival
On the Calvary Battle, nobody wants to be in Izuku’s team, but then, Ochako joins Izuku’s team, saying that it’s good to friends to team up. Unfortunately, when Izuku tries to recruit Tenya in his team, Tenya refuses. Tenya explains that while he sees Izuku and Ochako as best friends, he also views them as rivals. Tenya chose to be in Shoto’s team because his team is stronger than Izuku’s, and Tenya promises that he will defeat Izuku’s team.

Before the match between Ochako and Katsuki, Izuku offers an advice for Ochako whereas Ochako refuses to take his help, and then admit that she feels embarrassed for relying on Izuku during the Calvary Battle and declares that she will do her best to defeat Katsuki on her own. And when the match between them happens, Tenya asks Izuku what his advice for Ochako was, and Izuku says that she needs to strike first and touch Katsuki to send him out of bounds using her quirk.

Before the match between Shoto and Izuku starts, Tenya along with Ochako and Fumikage discuss how Izuku could win the match. After the match ended, Tenya with Ochako, Minoru and Tsuyu abruptly enter Recovery Girl’s room to check on Izuku and inform him that matches has been postponed to repair the arena which Recovery Girl forces all of them all to leave so she can prepare for surgery, further worrying Tenya and the others.

After the surgery done, Izuku returns to the stands in time for Katsuki and Eijiro’s match. He’s upset that he missed both Tenya and Fumikage’s victories (Tenya won against Ibara and Fumikage won against Mina). Tenya happens upon Izuku, who congratulates him on his victory and suggests Ingenium must be proud. He tells Izuku that he tried to inform Tensei but to no avail and that he will hopefully be able to later notify his brother of further victories in the festival. After the match between Tenya and Shoto, and Tenya doing some things we didn't see on sceen, Tenya reunites with his class, greeting Ochaco and Izuku with a smile until his phone rings. He pardons himself to speak with his mother, who informs him that his brother has been severely injured by a villain.

Vs Hero Killer Arc
It’s raining, Izuku walks to the school using his umbrella while muttering that it’s only morning, but he’s already tired, and he stops on his track after hearing Tenya greet him with a good morning while running, Izuku is incredibly surprised seeing Tenya wearing a poncho and rain boots. Tenya scolded him for walking so slow and saying that he’s going to be late. Izuku panicked and run with him while saying “Late? There are still 5 Minutes until the first bell” and then Tenya replies by stating that UA Students should always arrive 10 Minutes early. After they’re arrived, Izuku tries to start a conversation awkwardly, but Tenya cuts it by telling him if it’s about his brother, there’s no need to worry and apologize for worrying Izuku needlessly with a non-assuring smile and leaves. Izuku only stares at him with a concerned expression but no words.

At the end of the school day, Izuku agrees to walk home with Ochaco, who notices Tenya has already left. Before they leave, All Might suddenly appears in the doorway and takes Izuku aside to inform him about his nomination. All Might discloses that his former homeroom teacher, Gran Torino, extended the offer to Izuku and that he knows about One For All. Izuku is excited to hear the news, but All Might appears to be fearful as he's reminded of his old teacher. Meanwhile, Eraserhead notices that Tenya chose a lower class offer from a hero in Hosu City.

Izuku reunites with Ochaco and informs her that he got an offer. They both notice Tenya has left school already and Izuku recalls hearing about Ingenium on the news, having been taken out by the Hero Killer: Stain. On the first day of the internships, Shota dismisses the students after giving out their costumes. Before Tenya leaves for Hosu, Izuku and Ochaco approach him. They advocate for him to talk to them if he's feeling helpless and asks if he's comfortable doing so because they are all friends. He affirms their friendship and walks away, changing his expression from a smile to a vengeful glare.

In a train where Gran Torino and Izuku rides to Kyushu, Izuku wonders about how Tenya is doing and worrying him, and suddenly, the train they rides got attacked by a blue Nomu. Gran Torino told Izuku to sit down and then he kicks the Nomu away. But Izuku didn’t listen and get off the train and ran away, worrying about Tenya whose internship location is there. While Izuku is thinking how and how, he suddenly heard someone calling Tenya’s name; “Tenya-kun!”. Izuku stops on his track after he heard that voice. And the voice didn’t just call Tenya’s name once, but twice.

Izuku notices that it’s actually from the Normal Hero: Manual. Manual is looking for Tenya due to the chaos the Nomu’s made. He says vocally “Why did you choose a time like this to go off somewhere, Tenya!”. Izuku thoughts to himself in disbelief thinking the fact that Tenya went off somewhere in time as dangerous as that, ‘that diligent Iida’. He thinks that it’s weird for Tenya to go off with such a major incident in front of him.

Izuku starts to collect the puzzles; Hosu City, Tenya, Hero Killer. Izuku immediately starts to run into the dark alleyways searching for Tenya. After he finds Tenya, there’s Stain and another American’s Indian-styled hero called Native. Izuku jumps between the walls and then hit Stain’s cheek with a smash. Tenya stares at Izuku in disbelief and says “Mi… Midoriya?” and Izuku replies that he’s there to save Tenya.

Stain warns Izuku that it's his duty to kill Tenya, and if the young man gets in his way that the weaker of the two powers will be culled. Intimidated, Izuku realizes that Stain is a totally different breed of villain than those at the U.S.J. and decides to send out his location information. Tenya pleads for Izuku not to get involved because it has nothing to do with him but he refuses, re-stating words he had once heard from All Might: That the essence of being a hero is meddling where they don't have to.

Back at the hospital after the fight with the Hero Killer, Tenya tells Izuku that his hand has received serious damage. Although it can be healed through surgery, Tenya states that he won't get it healed until he's become a true hero and use it as a reminder of his foolish actions. Izuku can relate and says he will do the same with his crooked hand. They make a pact to become strong together, but Shoto feels guilty that they both hurt their hands in skirmishes involving him. Shoto claims he isn't joking, but Tenya and Izuku laugh in response.

Tenya and Eijiro blurted out Momo’s name in different ways at the same time; Tenya with a shocked voice meanwhile Eijiro with a happy voice.

Izuku said that he don’t know either, but after hearing that he could still reach, he couldn’t just sit still, and then he brought his head up continuing his sentence; he can’t help thinking that he want to save Katsuki. Tenya grits his teeth and saying in defeat, stating that since they can’t come to an agreement, he asks them to take him with them too. Which making everyone except Tenya gasped in surprise because they didn’t expect that to happen, Tenya then apologizes to Izuku for hitting him.

Fanon
The shippers ship this because of the closeness of their relationship, and the fact that both Tenya and Izuku are huge nerds. Tenya was one of the first people to impact Izuku and be impacted by Izuku. Some shippers tends to ship them with Ochako in a poly ship because they’re often seen together. The popularity of IidaDeku isn’t as popular as the other ships, rivalling IzuOcha, TodoDeku, IidaOcha and TodoIida. IidaDeku is Tenya’s 4th most popular ship and Izuku’s 13th most popular ship. There's a joke by an IidaDeku shippers on Tumblr; "Ochako is trying to have a romantic floaty moment meanwhile Izuku is getting sweaty picturing the shape of Tenya's flexible body". For context: When Ochako's crush for Izuku got revealed, Izuku is training his feet for his special move. Because Tenya is the one who teach him how to kick, he thinks about Tenya while training, Ochako is floating and see Izuku training through the window.
