The Law of Sidekicks is a Great Law that rules over how and when superheroes have sidekicks. This Great Law has resulted in some of the most well known wannabe superheroes, including Robin and the Winter Soldier.
For every superhero, said superhero shall have at least one sidekick during his superhero career. This sidekick must accompany said superhero for at least one year to satisfy the Law of Sidekicks. As determined in the case of Batman v. The Universe, a superhero may take on more than one sidekick at a time. This law shall be suspended any time by the superhero by means of the Law of Grit.
