i have a headcanon where sonic basically raised tails (which is canon as far as i’m aware) but temporarily tried to give him up to vanilla after realizing how dangerous it would be to have a kid as young as tails in life-or-death situations, and believing that vanilla could provide the stability sonic just couldn’t given that he’s a teenager and constantly a target for villains (eggman mostly). it didn’t last long as tails and sonic were both miserable at being separated and tails came back to be under sonic’s wing, but sonic still feels guilty over not being able to give tails the childhood he deserves. he still lets tails sleep over at vanilla and cream’s though whenever he’s going somewhere he deems too dangerous for tails. sonic sometimes stays at vanilla’s too after being away from home for a while.
another headcanon i have is that tails and sonic have a mix of a brotherly and parent-child relationship due to the parentification of sonic, what with how he raised tails despite having been a child himself, but they don’t often acknowledge it. sonic will call tails “little buddy” and rarely “kit/kid”, and tails mostly refers to sonic by name. when referring to each other though they’ll sometimes say “my brother”, but that’s the furthest they’ll really get. i think they’d be too worried about overstepping.
but i also imagine it’s only in highly emotional and distressing moments involving tails that sonic will refer to him as “my kid”…
Highkey facts, I like this headcannon. Sry I left you waiting for so long monarch. I like hearing other peoples headcannons
