The U.A. Traitor in My Hero Academia is revealed to be Yuga Aoyama, a flamboyant student from Class 1-A, who was coerced into spying for All For One because the villain threatened his family after giving Aoyama his Navel Laser Quirk when he was born quirkless. Aoyama, filled with guilt, relayed vital information like training camp locations to the villains but, upon discovery, his classmates and teachers showed empathy, seeing him as a victim, and encouraged him to help fight for good instead of punishing him.
The ua traitor is revealed to be Yuga Aoyama, Who was forced to be the traitor cause AFO was threatening to end his family if he didn't comply.
The "U.A. Traitor" is revealed to be Yuga Aoyama. He was born Quirkless, and with his parents both coming from wealthy backgrounds, they made a deal with All For One to give him his Navel Laser Quirk in a desperate move to grant their son a happy, successful life.
The UA traitor plot fell into the background for a long time, but recently came to a head in season 7 as Tohru Hagakure caught Aoyama relaying information to his parents for All for One's use and finally unmasking the traitor's identity, even if there are mitigating circumstances.
My Hero Academia (MHA) features a few canonically LGBTQ+ characters, primarily villains, including Himiko Toga (bisexual) and two confirmed transgender heroes/villains, Tiger (trans man) and Magne (trans woman), who defy norms, while some other characters have fan theories or ambiguous hints but lack official confirmation.
My Hero Academia: Aoyama's ending explained
However, it wasn't until My Hero Academia chapter 337 that Aoyama and his parents were revealed to have been working for All For One. While the news caused panic in Class 1-A, Deku forgave his classmate, telling him he could still be a hero.
Tenko Shimura ( 志 し 村 むら 転 てん 弧 こ , Shimura Tenko), also better known as Tomura Shigaraki ( 死 し 柄 がら 木 き 弔 とむら , Shigaraki Tomura), is the main antagonist of the My Hero Academia franchise.
Despite seeing himself as a reprehensible villain, Yuga is genuinely kindhearted and desires to do good. He shows this during the Provisional Hero License Exam when he was willing to throw away his chance at a license to give Tenya Ida the opportunity to pass.
As of the last chapter, Aoyama is engaged to Moka.
U.A.'s Big Three represents the top hero candidates in all of Japan. Mirio Togata, Tamaki Amajiki, and Nejire Hado did not rank well in their previous U.A. Sports Festival, and their strange personalities leave a strong impression on most people.
She then realizes that Yuga Aoyama has been the U.A. traitor the whole time. His parents remind him of the mission to bring Deku to an unsuspecting location, reminding him of everything he had done for them. It is revealed that Yuga was born reckless and received his Quirk from AFO.
Toru was seemingly revealed to be the "U.A. Traitor" in Chapter 335 of the manga at first, but this turned out to be a red herring as it was revealed that she was the one who found out that Yuga Aoyama was the real traitor, though he wasn't evil either as he was only a blackmailed pawn.
There's no single "saddest" death, as it's subjective, but popular choices include Himiko Toga's self-sacrifice for Ochaco, showing her desire for love; Magne's brutal murder by Overhaul, devastating Twice and Toga; Oboro Shirakumo's (Kurogiri's) tragic origin as a Nomu, impacting Aizawa and Present Mic; and Midnight's lonely, unceremonious death while fighting as a hero, highlighting the harsh reality of their world. Other contenders often mentioned are Sir Nighteye and Twice.

At the same time, Dabi climbs the steps of the villa towards their location with a sinister grin on his face, realizing that Hawks is a traitor. Dabi's inner monologue doesn't blame Twice for trusting him because he believes scummy heroes are always to blame.
My Hero Academia features several canonically LGBTQ+ characters, including Himiko Toga (confirmed bisexual by creator Kohei Horikoshi) and two transgender characters: Magne (transgender woman) and Tiger (transgender man) from the Wild, Wild Pussycats, who have received official confirmation and in-story representation.
Mio is currently the only person who could touch Aoyama without him fainting. She is hinted to have developed a crush on him after her classmate pointed out their closeness. Yuri Tamaru is Gaku Ishikawa's girlfriend and one of Aoyama's fans.
There's no single "worst" quirk, as it depends on the criteria (uselessness vs. self-harm), but strong contenders are Gecko (Spinner's weak wall-clinging), Self-Detonation (a one-time-use death sentence), and Pop Off (Mineta's sticky balls), though Mineta's clever application makes it surprisingly versatile. Other contenders include Quad Arms (extra limbs with minimal power) and Poison Gas (harms the user).
Weather Manipulation: Nine's original Quirk allows him to control and manipulate the weather itself. As a result, he can create deadly thunderstorms that can struck down lightning, creating massive collateral damage.
At the conclusion of the My Hero Academia manga, Mirio Togata (Lemillion) becomes the Number 1 Pro Hero, followed by Shoto Todoroki (Number 2) and Mt. Lady (Number 3), with Izuku Midoriya (Deku) ranking at Number 4. Deku achieves the status of the "greatest hero" by inspiring the world, even if he isn't officially Number 1, while Mirio's popularity and heroic image secure his top spot.
Yes, in the manga's final chapters, Deku does lose the power of One For All, becoming quirkless again after the power fulfills its purpose of defeating All For One, though faint "embers" remain temporarily before fading, allowing him to transition into a new phase as a teacher inspired by his journey. The power's will was to end, not be eternal, making his final state a deliberate, poetic conclusion to its generational cycle, freeing him from the burden.
The rarest Quirks in My Hero Academia are often considered to be New Order, due to its reality-bending power and single-user history (Star and Stripe), and unique genetic mutations like Eri's Rewind, which are completely outside the family lineage, alongside powerful, almost mythical types like All For One (ability to steal/give Quirks) and sentient ones like Dark Shadow, though specific examples like Healing/Regeneration and Warping/Teleportation are noted as extremely uncommon globally.
Eventually, he recognized that his anger had never truly been about Deku. It had always been about himself. That realization became his turning point. For the first time, Bakugo faced his own reflection and apologized—not just to Deku, but to the boy he had once been.
