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.
