Origin story facts for kids
In entertainment, an origin story is a story that tells how a character or group of characters became the way they are. Very often, it adds to the main story. In comic books, an origin story explains how certain characters obtained the powers they have (often superpowers), or how they became a hero or villain. When the comic or book is successful and grows older, origin stories are often rewritten and extended.
