LEGO Captain America Civil War is a subtheme of Marvel initially released in 2016 based on the film Captain America: Civil War produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures. Sets are based on the film's plot in which political pressure mounts to install a system of accountability when the actions of the Avengers lead to collateral damage. This deeply divides members of the team as Captain America believes superheroes should remain free to defend humanity without government interference and Iron Man sharply disagrees and supports oversight.
The LEGO Marvel Super Heroes theme is based on the characters created by Marvel Comics. Originally Marvel was a subtheme of the LEGO Super Heroes theme but was later separated into its own theme. Over time, sets in the Marvel Super Heroes theme includes most characters and situations released to the marvel Universe from films to the comics to TV series.
