Across their interactions, Peter becomes a true hero, internalizing the iconic mantra of great power and responsibility.
9. Hazbin Hotel Season 2
Showrunner Vivienne Medrano's boldly transgressive mature musical-comedy series, which originated as a fan-funded short, fully came into its own in its second season.
