Quirk: Bio-Virus is a ''Manga/MyHeroAcademia'' Fanfic written by [[https://archiveofourown.org/users/Void_Progenitor/pseuds/Void_Progenitor Void_Progenitor]]. It details the events surrounding Izuku's rise as a powerful vigilante, his role as a teaching assistant, and of course, his care for five girls who desperately crave the love and care they want.

!!Quirk: Bio-Virus contains the following Tropes

* AbusiveParents: The Togas were probably even worse than canon.

** Reiko loses her parents in a hate terrorist attack, has her apartment burned down, [[EyeScream loses an eye]] and is heavily crippled. Fortunately, Izuku repairs the damage to her body, but she is left a ward of UA.
* AdaptationalExplanation: In canon, One for All was assumed to be impossible to take due to the inherent nature of it. Here, Izuku explains that One for All, like his Quirk, Bio-Virus, is a compound Quirk, and since All for One can give and take one Quirk at a time, two quirks that merge perfectly is very much something he can't take.

* AdaptationalSuperpowerChange: Instead of One for All, Izuku has a Quirk that produces an airborne virus, before All for One merged biomass manipulation to create Bio-Virus.

** Melissa had a quirk at birth that was located in muscle, heart, tendon and bone marrow tissues, giving her the muscles and stamina of a super gymnast. It's also what causes Izuku to gently tell her that she cannot inherit One for All without causing her death, but assures her he'll train her to be a hero.

* BerserkButton: ''Don't'' say the girls under his care should be in a mental hospital. When All Might suggests this, Izuku freezes him in place and threatens him that if he tried to do it behind his back, he'll make sure All Might wished he died from All for One.
** While agreeing to the deal with Nezu, he warns Nezu that if anything bad happens to them, he would blow the whole school to smithereens.

* DeathByAdaptation: Inko and Hisashi were killed by All for One due to the latter being on his bad side.

* LivingEmotionalCrutch: Izuku is this to the girls under his care. Without him, they'd be abused, mistreated, abandoned or enslaved by various villain groups like the MLA.

** When Iida calls out Izuku (who is a teaching assistant) and Present Mic for inaccurate information and standing there, Izuku gives Iida a dressing down by telling him that by interrupting the meeting, he had effectively sabotaged the information gathering process, which was the number one cause of Hero deaths. When Iida tries to criticize Mei for having support gear, Izuku warned him that if he kept this up, his application to UA was revoked, and if he tried to sabotage Mei, he would ensure he is PersonaNonGrata in heroics.

* PoorCommunicationKills: As Izuku tells Iida and the audience, one of the leading causes of hero fatalities is a lack of information, misinformation or malinformation. By Iida's interruption, the audience would not get all the information they need, which, in a real-life situation, could prove fatal to them.

* VillainKiller: From Izuku's own words, he killed 3,016 criminals, saving millions in the process.

** Midnight and Present Mic's relationship is a lot more rocky compared to canon over what happened to her brother and his family.

* TheAtoner: Minoru Mineta ratted out all but his aunt (who was probably the only good person in his family), and was becoming a hero to atone for letting his family influence him into what he was in canon.

** All For One attacks the Midoriyas when Izuku was five, killing the parents as well as several people Hisashi was meeting with, while giving Izuku a compound Quirk.

** When Iida calls out Izuku (who is a teaching assistant) and Present Mic for innacurate information and standing there, Izuku gives Iida a dressing down by telling him that by interrupting the meeting, he had effectively sabotaged the information gathering process, which was the number one cause of Hero deaths. When Iida tries to criticize Mei for having support gear, Izuku warned him that if he kept this up, his application to UA was revoked, and if he tried to sabotage Mei, he would ensure he is PersonaNonGrata in heroics.
** The changes to the practical exam makes identifying [[BloodKnight Blood Knights]] easier, with Aizawa, Izuku and All Might showing distain at Bakugou's barbaric display on a villain bot while the UA staff were horrified.

* ShoutOut: Aizawa's mutated Quirk basically gives him the Sharingan from Naruto

* PoorCommunicationKills: As Izuku tells Iida and the audience, one of the leasing causes of hero fatalities is a lack of information, misinformation or malinformation. By Iida's interruption, the audience would not get all the information they need, which, in a real-life situation, could prove fatal to them.

** Melissa was bullied and teased for wanting to be a Quirkless hero, then mocked for not staying on the path she originally wanted to go down.

* AdaptationalRelationshipOverhaul: In canon, Ochako was a love interest for Izuku, Mei was his support item and costume designer, Momo was a classmate, Melissa was largely a movie appearance and Himiko was an enemy. Here, all five of them are deeply close to Izuku due to his deep caring demeanor for the five.

* RelatedInTheAdaptation: Midnight is Izuku's aunt in canon, being the sister of Hisashi. The moment she sees her nephew, she is given a CooldownHug while crying TearsOfJoy.

* ExactWords: Izuku offers him two files for Nezu to choose from. One containing the blackmail material to force the UA board to give him what he wants, and the other to put certain board members behind bars. Nezu picks the latter and Izuku casually opens the former's folder and puts the blackmail material in the latter folder as well. Seeing the Principal's curiosity, Izuku said that he was given a gift. He didn't say it would be only one file.
