History Fanfic / MyHeroPlaythrough

** In Chapter 24, Harley Quinn is revealed to have a similar power, except that hers works on ''all'' powers, requires tactile contact to take effect, and is [[PowerIncontinence always active unless she forces it not to be]]. Good to prevent heroes' Quirks from affecting her, not so good when Kurogiri is going to port her away from the USJ. Also, it does not protect her from a Quirk's secondary effects - for example, when Present Mic [[MakeMeWannaShout shouts]] at her, the shriek itself does nothing, but the stone shards the shout tears out of the floor cut her face and arms.

* IntimateHealing: A PG example. The TraumaInn effect that completely heals Izuku's wounds and replenishes his stamina overnight can propagate to a Party Member if they sleep in close proximity to him. How close they have to be to trigger the effect has yet to be established. Sleeping under the same roof is shown to be insufficient, given that Inko never noticed anything despite being a party member for months. However, accidentally spooning with Tsuyu ([[BedmateReveal long story]]) is confirmed to do the trick.

* ButterflyOfDoom:
** After recognizing his new power, Izuku rushes home to study it. As a result, he is not there to slow down Sludge or inspire All Might, and Bakugou dies.
** Izuku and Tsuyu's Hero Costumes are different from canon thanks to Inko offering more input into their designs. Later on, [[AdaptationalModesty Momo]] and [[BadassLongcoat Kyoka]] too, due to Inko getting into the costume-making business.
** As in the canonical USJ StoryArc, Kurogiri randomly teleports Class 1-A across the facility for the other Villains to ambush each isolated group. Since the targets and destinations were really picked at random, Izuku ended up in the mountain area rather than the shipwreck zone and fighting alongside different classmates against different Villains.
** The reason Denki Kaminari doesn't exist here. Chapter 23 reveals that his mother was in the middle of a LoveTriangle with her two best guy friends in college. One of them was Denki's father, but in this fic's backstory, she ended up dating and marrying the other instead. From the readers' perspective, this divergence in the timeline RetGone'd Denki and resulted in Misuzu giving birth to a different kid inheriting her electrokinesis, but greatly improved by her husband's power over magnetism. That kid being, of course, Mikoto "Railgun" Misaka.
** The Sports Festival plays out differently from canon. The first round is a maze instead of an obstacle course, the second round is still a cavalry battle but with forty-four students instead of forty-two and taking place on an artificial beach instead of a flat field, [[spoiler:Izuku faces Todoroki in the final battle of round 3 instead of earlier and outright wins the First Year's sports festival. This also results in him being one of the five 1-A students with a huge amount of offers where in canon he had none.]]
** Because of his poor performance in the Sports Festival, [[spoiler:Monoma Neito is put on probation especially since he ranked even lower than Ojiro and Hagakure did without the excuse of being actively sabotaged like them, with the possibility of Kongou Mitsuko taking his place due to her reaching the final round.]]
** [[spoiler:Izuku finding Eri after the Sports Festival kickstarts the Shie Hassaikai Arc before the internships even begin. The resulting consequences are that the Shie Hassaikai are defeated long before their canon defeat, all traces of the Quirk-destroying drug Overhaul was working on is destroyed before it can be revealed, Izuku begins staying at UA before construction on the dorms even begin, Inko joins him at UA, and the two members who were not already captured by the heroes or police, Tengai and Rappa, are forced to join the League of Villains.]]
** Because Momo met Nejire earlier than canon, Nejire vouches for her and Kendo to another third-year, which gives them enough trust for that third-year to explain that Uwabami is a horrible choice for an internship, which got Momo and Kendo to change their choices.

* InUniverseCatharsis: Izuku [[TraumaButton doesn't cope well]] with a dungeon boss patterned after Bakugou, but Ami, who also suffered from his bullying, relishes the chance to beat him up in effigy.

* SpitTake: Izuku ensures that Ochako has swallowed her drink before he mentions [[spoiler:that the Guild hall costs a billion yen]], but she still looks like she just choked on it.

* InUniverseCatharsis: Izuku [[TraumaButton doesn't cope well] with a dungeon boss patterned after Bakugou, but Ami, who also suffered from his bullying, relishes the chance to beat him up in effigy.

** When pressed by the other 1-A boys over which girl he thinks is the best-looking, he answers with [[{{Invisibility}} Hagakure]], citing, "[[ExactWords I can't see a single]] [[AccidentalPervert thing wrong with her looks]]."

** One can make a case that ''Tsuyu'' is the real HaremSeeker of the story, albeit one by proxy. She has no real objection to the idea of Izuku getting himself a harem as long as she's in it and none of his hypothetical other girlfriends are "terrible evil bitches". Curiously enough, Tsu seems to be more against the idea of Izuku playing the field than him having long-term, ''actual'' relationships with other women.
