Return of the Shield Deku
Is a crossover fanfic between My Hero Academia and The Rising of the Shield Hero by Shadow_Overlord on Archive of Our Own.
- Adaptational Badass: Hagakure in this universe has already extensively trained her physical prowess and her Quirk by the time of the UA entrance exam: she is introduced as visible and capable of activating invisibility, which also extends to her clothes, at will. Some feats she displays during the exam also suggest she may even be the holder of One For All.
- Adaptational Early Appearance: Toru Hagakure, Hitoshi Shinso, Mina Ashido, and Himiko Toga (whose life has had a much better turn, as she a nurse at UA) all appear during the U.A. Entrance Exam.
- Adaptational Nice Guy: Itsuki is a lot friendlier with Izuku than he was with Naofumi, due to the both of them coming from superhuman worlds where they faced discrimination. He even goes so far as to publicly call out Izuku’s trial as a complete sham.
- Awesome, but Impractical:
- Izuku’s Hero’s Will Shield allows him to fire a magical arrow that ignores Defense and deals damage relative to his current highest stat (In this case, his ridiculously high Defense). The downside is that it requires him to sacrifice 99% of his HP to do so, an act painful enough to leave him immobilized for several minutes.
- Izuku’s Spatial Shield can let him jump freely between his world and Melromarc. However, it uses up all of his MP and SP in the process, as well as having a 100 hour recharge time.
- Battle Couple: Izuku and Raphtalia have become this during their time together in her homeworld.
- Beware the Nice Ones: Izuku states that his reason for wanting homeschooling to finish middle school is not really to avoid bullying from Bakugo and others but rather because the bullies would have a bad time in the hands of Raphtalia and Filo, which leaves Inko perplexed given how sweet the two girls are. Raphtalia's reaction to Fingers at the end of Chapter 3 is an example of how she can get if upset - and that's just after she has single-handedly destroyed a Zero Pointer at the UA exam.
- Everyone Calls Him "Barkeep": The bully with a Quirk that allows him to elongate his fingers is simply called Fingers. We are told that even his teachers call him that way, as hardly anyone remembers his real name (which has never been stated in canon).
- I Reject Your Reality: As Itsuki points out, Motoyasu would trust anything a pretty girl like Malty says regardless of evidence to the contrary.
- Irony: The bullying of Bakugo and his cronies indirectly causes Izuku to get isekai'd, as he finds the book that transports him to the Shield Hero world while taking shelter from them. Also because of that, the absence of Izuku causes Bakugo to survive the encounter with the Sludge Villain but with crippling damage.
- Laser-Guided Karma:
- With Izuku absent, Bakugo ends up rescued from the Sludge Villain anyway but not before taking long-term and possibly permanent damage to his lungs, suffering breathing problems since.
- Upon seeing Izuku for the first time since he disappeared, Fingers decides to still be a dick to him and also shamelessly hit on Raphtalia; he gets his fingers broken by her in response.
- Kangaroo Court: Itsuki calls out Izuku’s trial as being this: On top of Izuku not being allowed to defend himself, he points out how Malty is throwing around accusations without any evidence to back them up, and how the King is very clearly biased in her favor due to her being his daughter.
- Offscreen Romance: After being first seen when brought away to another world, Izuku comes back to his original world with Raphtalia, Filo and Raph-chan in tow, already in a relationship with Raphtalia (who is the same age as him here), so deep the two have already decided they'll get married after graduating from UA.
- Shipper on Deck: Izuku’s Shield is apparently trying to get him and Raphtalia together, going so far as to modify her physical aging to make her Izuku’s age.
