Features of the LEGO Extended Universe

The LEGO Extended Universe (LEU) is an American media franchise and shared universe, starring various titular popular characters independently distribuited by Warner Bros. Pictures and based on Lego constructions toys. The shared universe was established by crossing over common plot elements, settings, cast, and characters. Over the course of the films and related media, several teams and organizations have been formed, each with different aims and purposes.

Alternate Universes
Alternative universes are points within dimensions whose history mostly diverges at a specific time.

Post-credit scenes
Post-credits or mid-credits scenes are a recurring feature in the LEGO Extended Universe feature films starting with The Billion Brick Race, during which one or more shorts are shown before, during or after the final credits. Clips often foreshadow future movies and TV shows, solve a movie plot, or create a future arc.
