Damien Darkblood! Invincible season 4 finally brings back its most mysterious superhero

Like an out-of-shape superhero wriggling back into their old spandex suit, Invincible is bursting at the seams with heroes, villains, and other super-powered individuals who don’t fit neatly into a good/evil binary. With new characters showing up in nearly every episode, old ones often fall by the wayside, but in Invincible season 4 episode 4, the animated series finally circles back to someone who hasn’t played a significant role on the show since season 1: Damien Darkblood.
