Invincible Volume 1 - Family Matters Mark Grayson- just like his peers. He is a senior student at an ordinary high school in America. He has a crappy part-time job after school and on weekends. He's very fond of girls, but he can't quite understand them. He likes to hang out with his friends and stay up late on Saturday nights (until the good cartoons start, of course). The only thing that sets Mark apart from others is that his father is the world's most powerful superhero, and lately he seems to be inheriting his father's powers as well. “It is always long-lasting, well-crafted and stands firmly at the center of a genre that is said to be impossible to produce anything new from now on.” -From the foreword by Kurt Busiek
