It doesn't truly matter what we call the characters even ones that have canon names. But Chris and Clara are really overused within the fandom. Clara was taken from immortal and the restless and has never been confirmed as her official name.

Chris was fanmade the full name being Christopher, I'm thinking his name is Evan since it was decoded off the same book Cassidy was decoded from and even has a brother named Michael in The real Jake

Mrs Afton on the other is very debatable. Michael used to be called Terrance a lot before it came clear that his canon name was Michael. Occasionally Derek was used but I can't say how many times Terrance was used compared to it. I would love to see different looks and names on the Aftons.

Why does Mrs A always have to be a ginger head with green eyes for? Why does William need to have purple hair for or is that simply the fnaf communities way of letting go of William/Vincent is not purple?  Do the characters have to have their canonical outfit or are we going to get creative and make more outfits they possibly could wear?
