History Characters / OneForAllAndEightForTheNinthTheEnnead

* DidYouJustFlipOffCthulhu?: Mei spends most of her time during Yui's fight against Machia throwing jabs at the giant's UndyingLoyalty to All for One and Tomura, pointing out he is nowhere as cool or special as he believes he is, and Machia can't really prove her wrong as much as she wants to.

* [[AscendedFanboy Ascended Fangirl]]: A tokutatsu fan who gets to live her dream not only by gaining a PoweredArmor and becoming capable of growing to the size of a building, but she also gets the chance to renact a fight straight out of ''Ultraman'' or ''Power Rangers'' by fighting against Gigantomachia, the story's resident kaiju.
* DidYouJustPunchOutCthulhu: Yui beats the ever loving hell out of Machia during their fight, and since the titan is nor use to an opponent who not only fights back but also is far more skilled than he is, Yui and Mt. Lady are successful in defeating him.

* TeamNormal: She's the only Quirkless member of Izuku's BattleHarem. [[spoiler:At least until Izuku gives her a Quirk in chapter 33.]]

A [[JustForPun quirky]] first-year Support student who is completely lacking in social graces, but always bursting with ideas to make real through her impressive engineering skills. She's the second girl Izuku bonds with, the third to reach level 2 and the second to reach level 3 in the bond, and quickly becomes his support technician (and that of his polycule).

* RightForTheWrongReasons: [[spoiler:Izuku accurately predicts that is better to keep Star and Stripe away from Tomura after he gains All for One's Quirk, since New Order relies on knowing the targets real name, and they don't know which identity he goes by. Although he comes with this idea under the misconception that Mugen has successfully taken over Tomura's body, not that young villain has abandoned both his name of Tenko Shimura and the Shigaraki surname.]]

* AppropiatedAppelation: The Ennead was originally what Fumikage and Reiko called the group, and it stuck as their chosen name for the team they form.

* DarkAndTroubledPast: After temporarily bonding with them, [[spoiler:Toga]] finds out that all members of the Ennead had this in spades: Momo was burdened with the expectations of her family; Ochako was isolated by her poverty; Mei’s hyperactivity and Yui’s shyness drove people away; Tsu and Toru couldn’t hide the way their Quirks made things different for them; Nejire’s Quirk made people put her on a pedestal, where they projected their insecurities onto her, and Melissa and Izuku were Quirkless, so they weren’t well fitted wherever they were.

* {{Otaku}}: Yui is a massive {{Tokusatsu}} fan, and it shows. During Hikage's segment of ''Kyuseishu'', she ends up getting interested in ''Franchise/SpiderMan'' when she learns how much [[Series/SpiderManJapan Toei's Spider-Man]] influenced the genre years afterwards.

* ActuallyPrettyFunny: She's the only member of The Ennead who finds [[TheGadfly En's]] PunnyName between him and former sidekick Kagami (Both their names translates into "Smoke" and "Mirror") legtimently hilarious, while the rest cannot help [[LamePunReaction grumbling and groaning at the pun]]. Both reactions delighting En himself.

* TranquilFury: After the MLA ruins the polycule's Valentine's Day date, Yui keeps a very stoic facade to hide how pissed she is over their interefence. As soon as she spots a group of Liberation soldiers, she grows 10 meters tall and proceeds to trash the villains up.

* EvenTheLovingHeroHasHatedOnes: Sweet and caring as Ochako, she is not above hating someone if she gets really pissed. While at first Bakugo was the main target of her hatred, she later swithes it to Curious, after the ImmoralJournalist starts to slander Izuku as part of the MLA campaign. So it's a surprise to no one that as soon as Ochako finds out that that Kizuki is a member of the Quirkist organization, she proceeds to beat her up with no mercy.

* BrokenTears: While he often cries a lot, one of the moments where Izuku is genuinely heartbroken is when he sees Himiko's emotional breakdown, when the poor girl begs him and the girls to accept him so she won't be alone anymore, and the best he can do is to knock her out and hand her over to the autorities so she can be receive proper help.
