For a franchise known for its various television series, there have been plenty of Dragon Ball movies. Most of them are exciting, self-contained stories that introduce new villains for the Z Warriors to take down. How each one fits into the timeline is interesting because most aren't technically canon. In fact, they're set in their own parallel universe. Yet, they usually still acknowledge the events of the series, so most could be a part of the main timeline. The movies have a specific chronological order, and slot themselves at various points during the main narrative.
