Define Headcanon Meaning

Headcanon
Used by followers of various media of entertainment, such as television shows, movies, books, etc. to note a particular belief which has not been used in the universe of whatever program or story they follow, but seems to make sense to that particular individual, and as such is adopted as a sort of "personal canon". Headcanon may be upgraded to canon if it is incorporated into the program or story's universe.

In my headcanon, John and Mary bicker like siblings when they're around each other... They just seem like they're brother and sister to me!

Headcanon
(also written as "head canon," but it's really one word.)

An idea, belief, or aspect of a story that is not mentioned in the media itself, but is accepted by either the media consumer themselves or the fandom in general. If it is confirmed by the creator of the story, it becomes canon.

In Homestuck , a popular webcomic , many suspect the headcanon that the trolls are carnivores, because of their natural homicidal tendencies and sharp teeth. It's never explicitly stated in the comic that this is true, but it'd be kind of dumb to assume they're a race known for salads and ice cream sundaes.

Headcanon
The non-canon personal ideas, opinions and believes that certain person or group of people feels strongly attached to, about a certain work of fiction (book, movie, cartoon, anime series, manga, comic book, etc...)

Sometimes people put their own headcanons above the actual canon of what was actually shown.

Person A: Android 17 is barely SSJ3 level, and that is exaggerating! Goku in SSJ Blue could have defeated 17 with a single punch!

Person B: That is your Headcanon. If he is a SSJ3 level character, then why Goku fought 17 with SSJ Blue instead of SSJ3, like he did with Trunks in a previous arck? Also, how can a SSJ3 level character resist attacks capable of hurting SSJ Blue evolution Vegeta and SSJ Blue kaioken x20 Goku that are 20 times more powerful than a SSJ Blue, 17 received a kick from Jiren, meant for Vegeta Blue Evolution in episode 127, and also took an explotion from Jiren that was able to knock out Goku and Vegeta, and he was still able to fight, a SSJ3 level character shouldn't be able to do that!

HeadCanon
A HeadCanon is something that did not happen Canonically or Factually in an event(story, reality, etc.) but is something you would've liked to happen.

"I ship Name with Name. I think I would've liked if Event happened instead of Event."

"What? That's weird. Why do you think like that?"

"Oml, don't be a B¡tch. It's just a HeadCanon."

Headcanon
A headcanon can be seen as two things:
As a canonical fact in the game / anime / show that is either mentioned or not mentioned in it . But, it also can be a non canon fact that, basing it off other canonical facts in the game / anime / show, could make sense as canon.

Did you know that there is a danganronpa headcanon that says that there is a website based off canon stories happened in danganronpa 2? In the game, ghundam mentions it once!!

I think that teruteru could be headcanoned as bisexual ! He likes girls for sure, but in the game he shows some hint abput he may be interresed in guys too !
