A real-life superhero (RLSH)[1] is a person who dresses up in a superhero costume or mask in order to perform community service such as neighborhood watch, or in some cases vigilantism.[2][3][4]
Early examples of this type of behavior are reported from the 1990s. One example is Mexico City's Superbarrio Gómez, who, in 1997, donned red tights and a red and yellow wrestler's mask in order to organize labor rallies, protest, and file petitions to prevent families from being evicted.[5] A "real-life superhero community" in the sense of an online subculture began to develop in the mid-2000s.[6]
