* LovingParentCruelParent: The Loving Parent to her husband's Cruel Parent. She loved her children Tenko and Hana, but failed to stand up to her husband's regular abuse of them. Despite this, she would try to comfort them and was much more affectionate than her husband ever was.

* AllForNothing: After her husband was killed by a villain, she put her son, Kotaro, into foster care to keep him from harm and forbade All Might and Gran Torino from making contact with him. However, [[LockedOutOfTheLoop because he never understood the full truth behind what she did]], Kotaro soon grew up to be an abusive, hero-hating father and had a son named Tenko who would later become Tomura Shigaraki. Furthermore, Kotaro is murdered by his son [[TheDogBitesBack when the latter's Quirk first activated due to the former's abuse]]. Even further than that, she did all that so that she can better fight All For One, only for her grandson to become a tool for All For One to get One For All. [[FromBadToWorse To put things further]], all her efforts only resulted in [[spoiler:Kotaro being manipulated by [[EpicFail All For One himself]] into becoming a hateful adult and him stealing Tenko's original Quirk and giving him Decay instead, meaning Nana's efforts to protect Kotaro from her ArchEnemy just resulted in said ArchEnemy indirectly killing her entire extended family to fulfill his goals for immortality.]]

* TargetedToHurtTheHero: Nana Shimura's husband was murdered by [[BigBad All For One]] to spite her, the seventh holder of One For All, for opposing him. This is what convinces her to give her child Kotaro up for adoption while forbidding both All Might and Gran Torino from learning anything about him to keep Kotaro out of All For One's clutches. [[spoiler:Unfortunately, this backfired horribly in the long-term, as Kotaro became physically and emotionally abusive to his own family as a result of his ParentalAbandonment, creating the conditions that would turn her grandson into Tomura Shigaraki.]]

* LivingEmotionalCrutch: Though All For One had no material use for his brother, Yoichi's true value, which went mostly unknown to his brother, was being his only connection to his emotions in his life. [[DeconstructedCharacterArchetype This is not a good thing]], as Yoichi sparks in All For One the 'dream' of conquering the world and being forever feared and remembered. His death just triggers the villain to spend nearly a century ruining the lives of others in a convoluted plot to reclaim his most valued 'possession', and once Yoichi's vestige is well and truly gone, whatever theatrics, supervillainy, and angry outbursts keeping All For One in check vanish, resulting in a cold, hollow psychopath that now has nothing left to lose.

* MirrorCharacter: A flashback towards the end of the story shows that not only do he and Izuku have near-identical personalities, but very similar upbringings too; albeit with Yoichi's being even harsher. They were both children born with a great disadvantage and weak bodies who had brother figures (All For One and Bakugo respectively) with amazingly powerful Quirks who harshly bullied them in return, but with whom they also shared some more "geeky" interests as children (comics and hero trading cards respectively). The most succinct example of their similarities is when Yoichi stands up to his brother after the latter killed multiple anti-meta-people militia members in a display of defiance that's nearly identical with the series' opening scene of Izuku standing up to Bakugo for bullying some poor kid.

* OneHeroHoldTheWeaksauce: All Quirks have a LogicalWeakness to them, even All For One...except a fully mastered One For All. The drawback is actually having to learn to use it, but once they ''do'', it effectively has no exploitable weakness. A person who already had a Quirk ''does'' have a limited lifespan, but even then, a user without a pre-existing Quirk is able to bypass that problem entirely.

* MeaningfulName: En is written with the kanji for smoke (煙), referring to his [[SmokeOut Quirk]].
* NoFullNameGiven: There's no indication whether if En is his last or first name and whether if he qualifies under the NumericalThemeNaming that other named One For All holders have.

* TheLastOfTheseIsNotLikeTheOthers: {{Inverted}}, as he's the ''first'' holder of One For All. Given Kudo's MeaningfulLook at the hand that was holding Yoichi's at the moment of his death, it's implied that Yoichi, being the Quirk's original holder, was able to transfer his Quirk to him on touch, just like his Brother could. Every subsequent elder had to use the DNA method to ensure a successful transfer.

* TheLastOfTheseIsNotLikeTheOthers: All the wielders from the present day going back to the first holder, who was basically quirkless, lack combat-related quirks. The only exception is the 2nd Wielder and the 3rd Wielder, who both have quirks directly related to combat (Gearshift, to make projectiles more dangerous, and Fa Jin, to allow someone to store and release lots of physical force). This is fitting, since unlike the others they were both members of a rebel group that had to explicitly kill adversaries as they made their way to confront All For One at the height of his power.

* DeaderThanDead: While the physical bodies of the previous users of One For All are long since dead the vestiges have remained within the Quirk allowing them to serve as {{Spirit Adviser}}s for Midoriya. In the climax of the FinalBattle however the previous users realise that the only way for them to defeat Shigaraki is to forcibly transfer their Quirk's into him with enough force to shatter against a mental scar left behind from his battle with Star and Stripe which will have the side effect of destroying the original vestige. Kudo even tells Midoriya not to mourn their passing as at this point, they have all long been phantoms of their original selves and their only desire now is to finish the battle once and for all.

* BeCarefulWhatYouWishFor: By the climax of Izuku's fight with Tomura, the vestiges come to the conclusion that the only potential means of damaging [[InvincibleVillain him]] is to intentionally complete the AssimilationPlot All For One groomed him to achieve and "[[DeathOrGloryAttack give]]" Tomura One For All. Kudo points out that by exploiting the "forcible transference" aspect of Yoichi's Quirk (using the analogy of Bakugo passing Izuku some test papers by throwing them in his face) and the fact that the sub-powers of the other Quirk Factor can be separated from the main one, Izuku can use the vestiges like weapons, targeting Tomura's leftover psychic damage within the MentalWorld of the Vestige Realm and weakening him from within.

* DeconstructedCharacterArchetype: Of the LivingEmotionalCrutch character. It's eventually revealed that underneath all the lies and falsehoods he gives about his motivations, All For one ''genuinely'' did care about his twin, and was emotionally devastated by their separation, especially since [[KinslayingIsASpecialKindOfEvil his own actions seemingly made it permanent]]. This is notable, as the narrative repeatedly enforces the fact that beyond Yoichi, All For One is [[TheSociopath absolutely incapable of considering others in any capacity]], and actual revels in this as a strength. However, because All For One so adamantly believes VirtueIsWeakness, he's in self-denial about any positive qualities he may possess. This means that Yoichi's best efforts to make his brother understand that GoodFeelsGood were rejected out of hand, and his connection to Yoshi only made the latter a walking DoomMagnet for anybody that All For One saw as getting close to him or keeping them apart. Even when All For One lets slips in his final monologue that he committed so many acts of villainy because he believed it'd make him remembered forever in infamy, he still doesn't understand that he really wanted companionship and acceptance by others, being fundamentally incapable of recognising his inner weakness because of his overblown ego.
