canon-defiant headcanons you refuse to part with?

back in Ye Olden Days (like 2017), when basically no one except midori and taro had personalities and everyones profiles had the same placeholder line where their additional info was supposed to be, the fandom did the heavy lifting when it came to fleshing out the characters, and everyone developed their own personal interpretations of them.

nowadays they all have canon personalities, however bare-bones and lazy they may be, but i want to hear some headcanons that will always be canon in your hearts, damn whatever the actual lore of the game says. they dont even have to be old!!

an example of mine: with very few exceptions, i will always depict the rainbow 12 as childhood friends all living in the same time period. no one can take their friendship away from me!!!
