Today's post looks at just some of the ways in which these heroes have dealt with issues that may have changed lives for the better.
If you grew up in the 1970s (and lived in the UK) then there's a good chance that you'll remember The Green Cross Man. Played by former body builder (and at the time soon-to-be Star Wars actor) Dave Prowse, The Green Cross Man was a superhero who specialised in road safety. The character appeared in a series of public information films sponsored by the Central Office of Information, for the UK Department of the Environment. The Green Cross Man became a staple of British TV until 1990, saving lives by instilling viewers with an important message: "I won't be there when you cross the road, so always use the Green Cross Code."
A more familiar face that cropped up on TV screens during the 1970s was Spidey. However Marvel's mighty mascot ditched web-swinging in order to help youngsters with their reading. Appearing on TV show The Electric Company, Spider-man communicated through the use of word balloons to encourage kids to learn to read. The show may not have depicted Spidey as the most amazing arachnid in TV Land, but it certain got its viewers attention.
Next up another Marvel superhero tackling important issues was the Incredible Hulk. Whilst working as a school janitor, the Hulk's alter-ego David Banner uncovered a case of child abuse in the episode 'A Child In Need'.
The story was arguably one of the series' best episodes and helped to expose a subject that at the time was not being discussed on TV.
Following a similar theme Marvel also tackled child abuse in the pages of a one-shot comic featuring Spidey and Power Pack.
Published in 1984 in cooperation with the National Committee for Prevention of Child Abuse, the issue featured two stories.
The first story - written by Jim Salicrup - tells the story of a young boy abused by his babysitter, whilst the second story - written by Louise Simonson - saw Power Pack help out a young girl who was being sexually abused by her father.
The comic was designed to reach out to kids who were afraid to speak out and was given away for free.
Discussing the comic with Bleeding Cool in 2011, Jim Salicrup said: "I believe strongly in comics being an excellent way to communicate, and this was an important message for children."
He added: "Marvel chose to be associated with the subject in a positive way. Aware of the vast amount of younger fans they had at that time, the opportunity to do something to help prevent child abuse seemed like a smart and resonable thing to do."
And finally (for today at least) TV show He-Man and the Masters of the Universe regularly helped viewers by providing a moral message at the conclusion of each episode. The messages covered a variety of subjects (always related to each story) and were delivered by the heroes of the tale.
Here's an example from the episode 'Teela's Quest' about adoption...as told by Teela herself:
