The best shonen anime have complex stories and characters that get viewers invested in them. And when fans get hyped about a series, they start theorizing about the details and stories under the surface.
For this list, we'll be looking at some of the coolest shonen anime hero fan theories from around the Internet. They touch on topics like Katsuki Bakugo's anger problems in My Hero Academia, Yuji Itadori's true lineage in Jujutsu Kaisen, the possibility of Nami being the human manifestation of an ancient weapon in One Piece, and more.

Why is Bakugo so angry all the time? It could be his inborn personality, it could be his mother's abusive child-rearing methods, or it could be that thing his mom said about him having a superiority complex that's fed by constant praise. But this fan theory posits that the real reason might have something to do with his quirk.
Bakugo's quirk works by secreting nitroglycerin-like sweat from his palms. Nitroglycerin can dramatically lower a person's heart rate. In order to achieve homeostasis, his body could be producing huge amounts of adrenaline. This keeps him alive, but it also keeps him constantly stressed out and angry. That can't be good for him long term!Good theory?

Roy Mustang was raised by his aunt, Madame Christmas. She's a brothel and bar owner who also works as an intelligence operative.
RinKat posted a theory to Amino Apps that states that Madame Christmas isn't biologically related to Roy. Instead, his parents were either fellow intelligence operative or criminals with a connection to her who ended up passing away tragically and leaving their son to be raised by a woman who pretended to be his aunt. Either that, or she simply found an abandoned child, and didn't know who his parents were.
This theory works in concert with the popular idea that Roy is actually Xingese. His biological parents, in this scenario, are originally from Xing.Good theory?
Kite's Weapon Choices Aren't As Random As They AppearPhoto: Madhouse
Kite's Nen technique, Crazy Slots, lets him summon a sentient clown with a roulette on its tongue that lands on the numbers 1-9, and get a different weapon depending on the number. His inability to choose the weapon is a trade-off for increased power.
Redditor u/fhernaiz thinks that there's a good chance that the choice isn't entirely random. On more than one occasion, Kite criticizes the clown for giving him a 'bad roll' which the clown objects to. Ging also claims that Kite has a number he rolls when he's in a really desperate situation.
This likely means that while Kite himself doesn't get to choose his weapon, the clown does - and the clown chooses the best one for the situation.Good theory?
Kakashi's Ninken Are Therapy DogsPhoto: Studio Pierrot
Kakashi makes liberal use of Ninken, or ninja dogs, in both his battles and his everyday life. This has led some people to believe that Kakashi might actually be related to the Inuzuka clan - but it's possible that he has another reason - they double as therapy dogs.
From his father's suicide to his life as a child soldier and his teammate's violent demise, Kakashi has been to hell and back. It's extremely unlikely that he isn't suffering from PTSD or some other mental health issue. Dogs can be enormously helpful for helping a person cope with symptoms stemming from those things. It's possible that Kakashi's Ninken are also helping him deal with his painful past.Good theory?
