There are dozens of good Samaritan heroes doing important civic work all around the world. El Pea Tenito was inspired by Bogota's Super Civico, who wore yellow spandex and red underpants. Clean panther is a superhero in Nagoya, Japan whose main activity is picking up litter.
Los Angeles' El Peatonito is part of a subset of real life superheroes who are more focused on things like picking up trash and taking on civic issues than catching criminals in alleys.
These super citizens take their inspiration from comic books but in some ways have more ambitious goals than defeating a make believe villain. They are out to solve big societal problems. Wherever a city is plagued by traffic accidents, or people are living on the streets…these heroes heed the call of service.
