Super Grandma and Super Grandpa
The Unknown Super Heroes
Super Grandma and Super Grandpa were unknown superheroes and worked together on cases involving saving children in danger by using super magical powers. They each owned a safety training school that taught safety and martial arts to children to make them aware of stranger danger, stop, drop and roll, cyber bullying, and more. While they were working on a case, and trying to catch the criminals, something unexpected happened, their super magical powers might be handed down to their grandchildren.
