Mark Grayson is struggling with past decisions while an existential threat looms over Earth in the Invincible Season 4 trailer on Prime Video.

The series continues its penchant for bloody action sequences and humor while giving fans deep emotional moments. This time around, Mark (Steven Yeun) feels he could have done more to save people from the city’s most recent deadly attack. Omni-Man (J.K. Simmons) also surprises Mark by asking for his trust, no gimmicks or games this time. The unexpected trust exercise is a result of Omni-Man and the other superheroes needing Mark’s help to save the world from a threat that, as described by the logline, “could alter the fate of humanity forever.”
