Missy is the only daughter of Marcus Moreno, who is the leader of the superhero team, The Heroics. After her mother's death for unknown causes, Missy made her father promise not to fight with the Heroics any longer. He agreed to stay out of harm's way so she wouldn't lose him either. Missy isn't like her father and possesses no superhero abilities, so she was able to attend a normal school with the rest of the kids her age. She didn't have many friends and preferred to stay by herself.

Missy has long, wavy brown hair, she wears a black shirt with the design of a little skeleton with a speech bubble of a heart, stating "leave me alone". Missy wears a necklace, along with a communication bracelet that helps her talk to her dad.

Missy is sleeping in her messy bedroom… until she got woken up by her alarm clock. She gets up, and goes in front of the standing mirror. Shen then grabs a pink shirt.

“This one says, talk to me!”

she then grabs a black shirt with the design of a little skeleton with a speech bubble of a heart.

“This one says, leave me alone…. Perfect!”

after Missy is finished putting the shirt on, she goes to the kitchen, where she sees her father, Marcus.

“Morning, dad.”

she greets.
