My Hero Academia is one of the hottest shonen anime of recent memory, so it's natural that fans are trying to fill in plot holes that the series itself has yet to explore.
That's where these fascinating My Hero Academia fan theories come in. Like Naruto fan theories and Tokyo Ghoul speculations, these musings may offer answers to burning questions. Who is Izuku Midoriya's father? Who is the traitor Present Mic insists is feeding top secret information to the League of Villains? Why does Tomura Shigaraki walk around with a dismembered hand attached to his face? Maybe these theories can shed some light.
Dabi Is The Missing Todoroki Sibling
Shoto Todoroki has three siblings, but we only know two of them. Fuyumi is a schoolteacher who inherited an ice quirk from her mom, while Natsuo is a college student with unknown abilities. There's no available information about the eldest Todoroki sibling, but some fans have speculated who he might be.
One popular theory states he's actually Dabi, a member of the League of Villains. His age fits, as he's said to be in his early 20s, which could make him slightly older than the 22-year-old Fuyumi. Not only that, but his fire-based quirk could easily have been inherited from Endeavor.
Dabi also strongly agrees with Stain's low opinion of professional heroes. If Dabi were raised by a man who mistreated his wife and children - and practiced selective breeding to acquire a child with powers he wanted - it's no wonder that he feels that way.18,959631Is this theory plausible?
The Winged Nomu Is Katsuki's Childhood Friend
Nomus are monsters that are an amalgamation of different humans, and therefore they can use a variety of quirks. It's a pretty disturbing concept by itself, but there's a fan theory that makes it even worse. The Winged Nomu specifically targets Izuku, but there's no clear reason why.
According to this theory, one of the former humans this Nomu contained was one of Katsuki's childhood friends. This friend may have briefly gained control of the Nomu's consciousness and targeted Izuku, as that's what Katsuki and his friends did as children.11,4202,339Is this theory plausible?
Everyone Has A Quirk
While My Hero Academia canon states that 80% of the population has a quirk of some kind, some fans are skeptical of this claim. According to this theory, rather than being quirkless, 20% of the population simply has a quirk that's useless in most situations.
Reddit user /u/dakotathehuman gives a few interesting examples. A person might have been able to breathe in space, but spent their entire life on Earth and never found out. They might be immune to a specific poison that they never ingest. Or maybe their quirk is noticeable, but doesn't register as a quirk - like their bladder is exceptionally strong, or their farts are completely silent.
There's already an example of a seemingly quirkless person having an ability that no one realized he had. All For One's brother appeared not to have a quirk, but it turned out he had the ability to transfer quirks from one person to another. It's not a huge leap to assume that other quirks could be hidden as well.13,3503,189Is this theory plausible?
Hagakure May Have Descended From The Luminescent Baby
The first person to present with a quirk was a glowing baby who was born in Qing Qing, China. Could Toru Hagakure be a descendant of this child? Quirks are hereditary, and while Hagakure doesn't glow, she is invisible. She's also able to create solar flares by controlling how light refracts, which could also be how she avoids being seen.
Quirks are inherited, but often change and combine with other quirks with successive generations. Hagakure's invisibility quirk could easily have developed from the Luminescent Baby's quirk.8,0333,119Is this theory plausible?
