Real-life superhero
A real-life superhero (RLSH) 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.
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. A "real-life superhero community" in the sense of an online subculture began to develop in the mid-2000s.
