In fandoms that have two canons there occasionally are characters that appear in one canon, but not in the other.

I'll work here with A-Team, because that's where I encountered the problem. In the movie there is a character named Charissa Sosa (wikipedia and Imdb seem to disagree on how many S's). She most definitely is not a character from the TV show.

Now, what to do when she some how shows up in TV verse based fic, and the author has misspells her name? Would that create a mini or an OC?

(I'm in favour of a movie-verse mini, but mainly because I haven't got one, and minis are instant Rule of funny).
