Fan Casting Invincible in The Dispatch Boys

A teenage superhero with Viltrumite powers who is defined by the grueling transition from adolescent idealism to the harsh realities of intergalactic geopolitics. Initially, Mark views his powers through a lens of classic superheroism—saving people is a privilege and a moral imperative. However, his world is shattered by the revelation that the Viltrum Empire is a fascistic, expansionist regime, and his father was sent to Earth to prepare it for conquest. This betrayal forces Mark to redefine "Invincible" not just as a name, but as a testament to his emotional and physical endurance. Unlike many heroes, Mark is frequently beaten to the brink of death; his strength lies in his refusal to stay down.
