This category should be limited to comic book superhero style entries created in the Hero System. Other genres for Hero System have a separate category, as do other game systems.
Champions is the Hero System superhero genre. It was the first, and still most popular setting for the Hero rules; to many, "Champions" and "Hero System" are synonymous. It is also the most popular superhero rules system, largely due to the flexible character and power design rules, necessary to create superheroes, who, by definition, go beyond normal bounds.
Champions is also the name of the superhero genre book for the Hero System Fifth Edition, to be written by Aaron Alliston.
