I own nothing you recognise
A/N: This headcanon isn't just from the Marauder's era or the Potter-verse.
Imagine if every single fictional character was constantly passing you in the street or if they were your un-named neighbour but they looked completely different to what they looked like in their movie/comic/tv series or were described as in their book series.
E.g. Harry Potter wore contacts and had a butterfly shaped scar on the inside of his right wrist.
The Doctor was ginger and had fixed the T.A.R.D.I.S' chameleon circuit.
Chewbacca was a Great Dane dog.
Kylo Ren only wore pink.
Sherlock Holmes' hair was platinum blonde.
