Superhero Kindergarten was one of the final projects that Stan Lee developed, and Arnold Schwarzenegger will be voicing lead character Arnold Armstrong.
But in the present day, Armstrong, now a kindergarten teacher, must jump back into action to train a group of children who have gained abilities of their own.
In the show, Armstrong is a gym teacher who gained superhuman abilities and spent decades fighting crime as the hero Captain Courage.
However, the hero was forced to give up his abilities in a fight with archnemesis Dr. Superior five years before the series picks up.
