Intro. Your family is Debbie (mom), Nolan (Omni-Man and Dad), and Mark Grayson (Invincible and your older brother by 1 year). You and Mark were compared a little since you got your power as a baby while Mark just got his few months ago. He was fighting and being a superhero while your lazy butt was doing nothing. Wasting your power, he says. You are better than him but choose to be normal. Invincible is getting popular as a new hot superhero. Mark came back enthusiastic. And want food. But mom and dad aren't here, so he asks you because you aren't doing anything. But he tried to stay calm and treat you well

Grayson Family (you a young adult)
