* ForWantOfANail:

* HeroicSecondWind: [[spoiler:Just as All for One overwhelms Izuku in their fight with each other, All Might steps in to save Izuku. While All for One manages to sucker punch All Might, it gives Izuku the brief respite he needs to rejoin the fight and ultimately defeat him]].

* WouldHurtAChild: Dabi encounters Kota during the Training Camp raid and, after talking to the boy, proceeds to use his Cremation quirk on the kid.

** [[spoiler:''All For One'' dies in his battle with All Might and Izuku when Izuku reduces his upper half into a literal scorch mark with a WaveMotionGun move]].

* SuperMode: When Izuku is at his most enraged, is in a life or death situation or if his loved ones are in that situation, her takes on a form he dubs "Ragnarök". He grows to be 13-feet tall, he grows a pair of horns on his head and his eyes and embers go from orange to purple.

** In-canon, Izuku's father works overseas, hence why we never see or hear from him. Here, he was a pro-hero that died in the line fo duty.
** [[spoiler:All For One dies in his battle with All Might and Izuku when Izuku reduces his upper half into a literal scorch mark with a WaveMotionGun move]].
* FamedInStory: The first time Izuku shifts into his Ragnarök form, it was an accidental maneuver in reaction to a mugger shooting his mother in a public place. Videos of this transformation went viral on the internet, becoming famous as the "Demon Werewolf." Even four years later in his time at UA, people still recognize Ragnarök whenever they see it or the first time in-person.
* ForWantOfANail:

** In canon, UA doesn't become a boarding school until after All might retires. Here it's a boarding school from the start.
** In canon, Bakugo's antagonistic behavior, while acknowledged, is often brushed off as something they could work on later. Here it is taken ''very'' seriously. After Bakugo nearly collapses the entire building during the Heroes vs. Villains exercise to get to Izuku, All Might has him sent to the principle's office as soon as Recovery Girl is done with him. They have him transferred to Class 1-B as a warning, Vlad King having more experience dealing with rowdy students that fit Bakugo's profile. [[spoiler:Later, Bakugo continues to issue warnings that he will kill him himself, only to discover that Aizawa was hiding in the rafters of the room and Izuku was recording their conversation, getting Bakugo expelled right before they take their Hero Licensing Exams]].
** Izuku makes first-place in Aizawa's quirk assessment.
** In-canon, Izuku is voted to class rep, only for him to pass that onto Iida after he managed to calm down the students during the break-in.

* HeroicSecondWind: [[spoiler:Just as All For One overwhelms Izuku in their fight with each other, All Might steps in to save Izuku. When All For One sucker punches All Might, it had given Izuku the brief respite enough to rejoin the fight and ultimately defeat him]].

* TookALevelInBadass: While Izuku was impressive as he was, when All Might gives him One For All, it compliments his preexisting quirk almost as though they were meant for each other. For one thing, Izuku's transformations are much easier, capable of shifting between his human form, beast mode and Ragnarök without the needing to be threatened before hand, and even is able to take on a [[LittleBitBeastly "light"-mode]] that gives him a power boost without having to do a full transformation and waste energy. With his preexisting strength and HealingFactor, Izuku can tap into One For All's overwhelming threshold of power without breaking his limbs, though it does speed up quirk exhaustion. [[spoiler:The power boost it gives him was enough for him to defeat ''All For One'' the first time they meet]].

* AdaptationalBadass: While canon!Izuku was quirkless, here Izuku was born with a quirk with the qualities of the beast of Myth/NorseMythology Fenrir. He has SuperStrength, SuperSpeed, all of the enhanced senses of a wolf, a HealingFactor, the ability to exude smoke and embers he holds limited control of and a number of werewolf-esq {{Super Mode}}s he can shift between.

Common quirks are based on simple things. Even Bakugos strong flashy explosion quirk it just dynamite. But there is absolutely nothing simple about your quirk being based on the Norse God: Fenrir.

* DeathByAdaptation: In-canon, Izuku's father works overseas, hence why we never see or hear from him. Here, he was a pro-hero that died in the line fo duty.
** [[spoiler:All For One dies in his battle with All Might and Izuku when Izuku reduces his upper half into a literal scorch mark with a WaveMotionGun move.]]

* ForWantOfANail: Shoto Todoroki is a girl in this version, going by "Shoko", and has already started dating Izuku by the time their first day of class starts.

* HeroicSecondWind: [[spoiler:Just as All For One overwhelms Izuku in their fight with each other, All Might steps in to save Izuku. When All For One sucker punches All Might, it had given Izuku the brief respite enough to rejoin the fight and ultimately defeat him.]]

* SmartAnimalInconvenientInstincts: It is routinely brought up with those with animal mutations like Izuku, Tsu and Tokoyami tend to act on instinct in certain circumstances and can sometimes be a hinderance. With Izuku's power, he is often acknowledged as the apex and not much usually comes of it [[spoiler:until Monoma copies Izuku's quirk and uncontrollably shifts into his own Fenrir form, both Monoma and Izuku compelled by their instincts to fight for dominance.]]

** The fact that Toshinori starts dating Izuku's mother Inko and eventually marries her was completely by coincidence, though it was a lucky break for Izuku as Toshinori was able to get Izuku training for his beast-form by the Cougar Hero Prowler and control over his fire-based abilities by Endeavor. Izuku doesn't find out that his step-dad is All Might until this first encounter against the Sludge Villain and Inko doesn't learn this until [[spoiler:their fight against All For One]].

* TheAce: By the time Izuku makes it into his first class of UA, Izuku already won the SuperpowerLottery with his Fenrir quirk, but he has also learned how to use it by two long-accomplished Pro-Heroes (one of which being the Number 2 Hero Endeavor) and has an emergency hero license.

* AdaptationalNiceGuy: canon!Monoma was a concieted jerk who spends all of his free time mocking 1A out of an envy for their in-story fame. Here, [[DramaticIrony he possesses a hatred for]] people who pretend to be good, only to act in the contrary out of spite, [[spoiler:his best friend having died when [[FantasticRacism a hero ignored him because he had a "villainous" quirk]].]]

* DeathByAdaptation: In-canon, Izuku's father works overseas, hense why we never see or hear from him. Here, he was a pro-hero that died in the line fo duty.
