* InconsistentSpelling: His surname can be romanized as "Ida" or "Iida". The anime has gone with the latter, but the official Viz translations go with the former.: His surname's proper spelling is "Ojiro", but some non-Japanese-speaking fans incorrectly spell it "Ojirou", assuming it uses the same rule as "Bakugo/Bakugou" or "Jiro/Jirou".

** Confirmed in Chapter 336 and 337 when it's revealed that [[spoiler: Aoyama has been spending the past year in near-suicidal despair over his role as the [[ForcedIntoVillainy UA traitor]].]]

* VillainousBSOD: [[spoiler: [[ForcedIntoVillainy Though villainous is a big stretch]], Aoyama suffers this big time come Chapter 336 and 337, when Hagakure and Midoriya catch his parents trying to talk him down from revealing himself as the UA traitor, to the point that it almost borders on a DespairEventHorizon. When Aoyama finds out that the cat is out of the bag he falls apart completely, clawing at his own face and attacking Midoriya in a blind panic. After he is restrained and brought in front of UA, he spends the rest of the chapter with DullEyesOfUnhappiness.]]

* SleepsWithBothEyesOpen: As seen in Chapter 193, right before he wakes up because of [[spoiler:Midoriya's quirk awekening.]]

* SpellMyNameWithAnS: His surname can be romanized as "Ida" or "Iida". The anime has gone with the latter, but the official Viz translations go with the former.

* SpellMyNameWithAnS: His surname's proper spelling is "Ojiro", but some non-Japanese-speaking fans incorrectly spell it "Ojirou", assuming it uses the same rule as "Bakugo/Bakugou" or "Jiro/Jirou".

* SpellMyNameWithAnS: His first name can be spelled "Eijiro", "Eijirou", or "Eijirō".

* VerbalTic: "Kero", the Japanese onomatopoeia for a frog's croaking, naturally. In English, it becomes "ribbit".

* {{Foil}}: To Bakugo. Both of them come from wealthy families, are some of Class 1-A's smartest students, are [[LightningBruiser hard-hitting and fast-moving fighters thanks to their Quirks (Engine for Iida, Explosion for Bakugo)]], initially dislike Midoriya and passionately follow their ideals of what a hero should be. However, they easily contrast one another: starting from their Hero Costumes, [[RedOniBlueOni Iida's is white and navy armor, indicating his straight-laced and rule following personality while Bakugo's is black and orange cloth, which matches his fiery personality as well as his status as an AntiHero.]] Iida's Quirk, Engine, comes from his legs while Bakugo's, Explosion, is connected to his palms that can malfunction due to overuse (Iida's Engines lose fuel if he doesn't drink enough orange juice, Bakugo's forearms start to ache if he uses more powerful explosions). Both of them tend to struggle in social situations due to being too loud and intense, though Iida is a NiceGuy who is very passionate about following rules while Bakugo is a {{Jerkass}} who has a volatile temper and very foul mouth. Both of them have [[ColorMotifs colors they associate with (Blue for Iida, Orange for Bakugo)]] and an AnimalMotif (horses for Iida, dogs and tigers for Bakugo) to symbolize their contrasting personalities (earnest, polite, and a rule follower for Iida, rude, selfish and violent for Bakugo). Both Iida and Bakugo initially dislike Midoriya (Bakugo because he believes Midoriya looks down on him, Iida because he disliked his interruption of Present Mic's speech), though Iida quickly warmed up to Midoriya and became his best friend while Bakugo hated Midoriya for nearly three seasons until they finally started to work towards reconciliation. [[{{Hypocrite}} Despite Iida's reverence for rules and order, he has broken the law twice (first when he went up against Stain, second when he helped in rescuing Bakugo)]] while in spite of Bakugo's hatred of rules and status as a delinquent, he has never broken the law.

* HumanoidAnimal: Part human, part frog.

* VirtuousCharacterCopy: He is, at first glance, a dead ringer for Yukio from ''Manga/{{Blue Exorcist}}'' -- both are tall mature-looking guys with glasses, being overly serious workaholics who idolize their older brothers but are also prone to competitiveness and self-deprecation. But while Yukio is kinda mentally unstable, prone to abuse his brother Rin and [[spoiler: even briefly does a Face-Hell Turn]], Iida is only briefly snaps at Midoriya for his seemingly reckless behaviorand is otherwise friendly and loyal to everyone his classmates.

* GyaruGirl: Of all 1-A girls, Mina has this aesthetic, having pink and unruly short hair, tanned pink skin, and a very fashionable hero costume that contains a fur collar on her vest and patterns on her bodysuit, all to fit her carefree and energetic personality.

* AnimalMotif: Horses. In a lot of fan arts with Iida, he is often seen depicted as an anthropomorphic horse or riding one. His Quirk and fighting style are also reminiscent of a horse: he has great speed and is a heavy hitter thanks to Engine enhancing his kicking strength. His Hero Costume is also a gleaming white color, which is often the color of horses. Just as horses carry a lot of burdens due to how valuable and strong they are, Iida himself also carries much burden due to being the de facto leader of Class 1-A when Aizawa isn't around.

* BequeathedPower: [[spoiler:He was not born with Navel Laser. It was given to him by All For One as part of a deal his parents made, and was most likely previously a Quirk stolen from someone else.]]
