In Character

In Character (often abbreviated IC) means a character behaving as he should. Canon characters are only in character if their personalities merge with what is known about a certain canon; this is found in the canonical world itself and in goodfic. Any deviation from this renders the canonical OOC, or out of character. The extent to which a canonical is in character can be determined from a Canon Analysis Device.

It is not to be confused with the other IC, an occasionally-used acronym for the Department of Implausible Crossovers.
