In a world filled with DC and Marvel icons such as Superman, Batman, and Spider-Man, it’s tough to create a new, popular superhero. But back in 2005, with the launch of the “Invincible” comic book, that’s exactly what Robert Kirkman (“The Walking Dead“) did. He took all that was great about the power and stature of Superman, combined it with the everyday teen problems of Spider-Man, and then added some good ol’ ultraviolence for flavor. The result is one of the best superhero comic books of the past 20 years, and a brand-new Amazon animated series.
