* BlindingBangs: Has these like in the flashback image in the manga.

* HeterosexualLifePartners: Implied he will be this with Todoroki, as they get older. The author has stated the two are (or will be) in a queerplatonic relationship, as, within the world of the story, Midoriya is aromantic and Todoroki is demiromantic.

* LongLostRelative: [[spoiler:Hino reveals that [[RelatedInTheAdaptation Dabi is a Todoroki]]]].

* {{Asexuality}}: Todoroki is confirmed to be demisexual.

* PlatonicLifePartners: He involves into this with Izuku. Both boys are {{asexual|ity}} but develop a deep bond.

Izuku's best friend and CanonForeigner, Rei is a mute ghost who died under mysterious circumstances and considers Midoriya her 'little brother'. [[spoiler:Her real name is Morigawa Hitomi, and she was a test subject for the Noumu project before dying 30 years previously]].

* HeterosexualLifePartners: With Amakiji.

* AmplifierArtifact: One For All acts as one for his original Quirk, allowing [[spoiler: ghosts near him to interact with the world more. It's gotten to the point where, with One For All active, they become visible to others and attack others, seen best when Rei tackled Bakugou to the ground when he and Izuku were having an argument post-League of Villains. Later, he's able to use this on Chisaki's victims, giving him a veritable army to take the man down.]]

** Izuku [[spoiler: partially breaks his right wrist to free his hand and bites Himiko on the nose for his plan to free himself and Bakugou.]]

* TheDarknessGazesBack: Midoriya has [[https://en.wikipedia.org/wiki/Tapetum_lucidum tapetum lucidum]], which makes his eyes glow like a nocturnal animal's in the dark (which tends to scare his friends when they're not expecting him), and pictures of him tend to have glowing red eyes. [[spoiler: Dr. Tsubasa]] speculates it's a physical manifestation of his "invisible quirk".

* StressVomit: Happens after his incident with Shigaraki at the shopping mall [[spoiler: and after being released from Compress' containment orb]].

Izuku's best friend and CanonForeigner, Rei is a mute ghost who died under mysterious circumstances and considers Midoriya her 'little brother'. [[spoiler: Her real name is Morigawa Hitomi, and she was a test subject for the Noumu project before dying 30 years previously]].

* BigSisterInstinct: She feels very protective towards Izuku, who she thinks of as her little brother. Unfortunately, there's not much she can do to protect him [[spoiler: yet. It seems One For All is strengthening Midoriya's ISeeDeadPeople quirk, gradually making ghosts near him stronger to the point of being able to interact with people. She's eventually able to actively protect Midoriya by tackling Bakugou when he tried to attack him]]. She's also fond of Eri, who reminds her of Izuku when they first met.

* DarkAndTroubledPast: A poltergeist who [[spoiler: was an unwilling test subject for All For One's Noumu experiments, suffering horrific trauma at the hands of his scientists until she was rendered brain-dead.]] It's such that she doesn't ''want'' to remember her past, vastly preferring her new "life" instead as Rei.

* GhostAmnesia: She doesn't remember [[spoiler: being killed by All for One's Noumu experiments]].

* {{Poltergeist}}: [[spoiler: And unlike normal poltergeists who will typically revert to normal ghosts when they stop stressing out, Rei is like this permanently due to the intense trauma she suffered from being a test subject for Noumu experiments.]]

* SuddenlyVoiced: She speaks for the first time in chapter 39 when she [[spoiler: rejects her human name]]. Izuku notes he's never heard her voice in the ten years he's known her.

[[folder: Overhaul]]

* BadBoss: Kills his subordinates for the slightest mistake. [[spoiler: It actually backfires on him, as many of his ghosts were former subordinates, and were not happy with him. They took the chance Midoriya gave them to get revenge very gladly. ]]
* MadeOfIron: It takes [[spoiler: Midoriya and Nighteye working together, then Midoriya [[CurbStompBattle beating him up]] as a ghost, then Midoriya empowering all of his victims' ghosts, and finally Mirio stepping in to finally take him down]].
* WouldHurtAChild: Like in canon, Eri, who's blood he uses to manufacture the quirk erasing bullet. Also [[spoiler: Midoriya, a teenager, who he kills in their fight, although Midoriya does come back to life.]]

[[folder: Other Ghosts]]

* FriendlyGhost: He's a good man who helps Midoriya when he gets [[spoiler: captured by All For One.]]

* ButForMeItWasTuesday: Doesn't seem to recall the incident that traumatized Izuku enough to cause his first major bout of elective mutism. It's slightly ambiguous as to whether or not he didn't remember or was trying to bluff his way out of the confrontation; if the latter, it blew up in his face when Izuku folds it into his [[TheReasonYouSuckSpeech call out]].

* JerkWithAHeartOfGold: Enjoys playing pranks and scaring kids (though usually only Izuku's [[AssoholeVictim bullies]]), but is dedicated to Izuku's cause of helping everyone he meets.
