There’s something deeply satisfying about watching an absurdly powerful protagonist demolish their enemies. No tension about whether they’ll win—just pure power fantasy enjoyment as they casually handle threats that would destroy anyone else.

But not all OP protagonist anime are created equal. The best ones find ways to keep things interesting despite (or because of) their hero’s overwhelming strength. Whether through comedy, creative challenges, or exploring what power actually means, these anime deliver the OP goods while still telling compelling stories.

  • Genre: Psychological, Drama, School
  • Where to Watch: Crunchyroll
  • Why Watch: Ayanokoji isn’t physically OP—he’s mentally OP. Watching him manipulate everyone around him while pretending to be average is fascinating. It’s power fantasy for the strategists and chess players out there.

  • Genre: Action, Fantasy, Comedy
  • Where to Watch: Crunchyroll
  • Why Watch: Anos is the reincarnated Demon King, so powerful that killing him just makes him stronger. The show leans fully into the absurdity—he kills someone with his heartbeat. It’s ridiculous and knows it, making it pure fun.

  • Episodes: 10 (Complete)
  • Genre: Action, Horror, Supernatural
  • Where to Watch: Crunchyroll / Hulu

10. Saiki K.

  • Episodes: 120+ shorts (Complete)
  • Genre: Comedy, Supernatural, School
  • Where to Watch: Netflix

  • Episodes: 39+ (ongoing)
  • Genre: Action, Sci-Fi, Fantasy
  • Where to Watch: Crunchyroll / Hulu

12. Cautious Hero

  • Episodes: 12 (Complete)
  • Genre: Action, Comedy, Fantasy
