Invincible’s reputation for hyper-violence is well earned. The Prime Video show’s season 1 massacre of the Guardians at the hands of Nolan/Omni-Man (J.K. Simmons) is harrowing, and it sets the tone for the show’s commitment to realistic superpowered gore and destruction. And few scenes in television history are as gnarly or horrifying as the destruction of a train and everyone on board in the first season’s finale.
