A particularly large use of Retroactive Continuity (retcon) in which the very nature of an entire universe, usually a fictional universe, is changed. Any revision to a story in which essential details, and established facts are altered in such a way that nothing which has come before is sacred. Named for the propensity of DC Comics to rewrite the history of their comic universe every few years to fix mistakes in writing, or to update characters and situations that have been stated in the intervening years.
