The hero known as Secret was once an ordinary girl named Greta Hayes. She was murdered by her brother, Billy, who would later become the supervillain known as Harm. Because of the manner of her death, Greta remained stuck on this plane of existence, a gateway between the living and the dead.
- Non Corporeal Form Greta is technically dead, thus as a non corporeal entity she is for all intents and purposes invulnerable to all physical maladies, harm from anything physical.
