Dangler is a literary term meaning a plotline that remains unresolved or is metaphorically left to "dangle" or "hang": a type of major plothole. A dangler, or dangling plotline, is an unanticipated feature in fiction where a plotline is forgotten, phased out, or eventually dropped, thus a resolution is never achieved. Although dangling plotlines can occur in all forms of media, they typically appear in comic books, movies, and book sequels, where the original writer or creative team is frequently replaced.
