OOC

OOC = Out-Of-Character 

Refers to the fact that the characterizations used by an author are not those established by canon standards. Personality development flaws may be deliberate or accidental, for the better or (more likely) detriment to the story. Please note that even the most fantastical of AUs can be written with the characters still in-character, if one is careful.
