Japanese anime fans have just wrapped up the biggest debate on the strongest character in anime history, and the results are surprising: the top spot does not belong to Goku, Naruto, or Luffy. Nearly 20,000 fans voted on the site Minna no Ranking to find the most powerful character, and the winner is a “blue slime” with the ability to absorb, copy, and rewrite reality.
The winner is Rimuru Tempest

If you’re a fan of That Time I Got Reincarnated as a Slime, you know Rimuru Tempest is no ordinary isekai protagonist. Once an office worker, Rimuru was reincarnated as a slime and somehow became one of the most absurdly powerful beings in the anime world.
What truly sets this character apart from shonen heroes like Goku or Naruto is that Rimuru doesn’t rely on brute strength or flashy transformations. He is essentially a “walking cheat code” from the moment he appears.
Rimuru can devour opponents, steal their powers, and evolve into a godlike entity after every battle. Imagine Goku, Saitama, and Naruto combined, and Rimuru could still casually erase them from existence while sipping tea. That’s the level of power this slime possesses.
Because of this, Rimuru dominated the rankings, beating out main characters from Dragon Ball, One Piece, and Naruto. The deciding factors were not only raw power but intelligence, adaptability, and absolute unpredictability. Rimuru doesn’t just fight, he rewrites the rules of power. That’s why fans have crowned him the “Ultimate Being” in anime.
Japan’s Top 5 Strongest Anime Characters
After Rimuru claimed the top spot, who else made the list? Japan’s Top 5 lineup was revealed, forming a powerful team like a multiverse crossover event:

The results are undeniable: Zeno, Saitama, and Goku all fell short against the slime. Even Zeno, the god who can erase universes in Dragon Ball, only ranked third.
Naruto and Luffy fans were surely shocked their favorites didn’t make the Top 5. However, this lineup highlights the fact that Saitama’s strength is mostly physical, while Rimuru’s abilities transcend physical laws and can destroy reality itself.

Although Japan’s voting results are final, the debate among fandoms continues. Some argue Saitama hasn’t shown his full power yet, others believe in Goku’s limitless potential, and Naruto fans hope for a retcon to boost their hero’s strength.
But numbers don’t lie. Japan has spoken, and the slime monster from That Time I Got Reincarnated as a Slime sits at the top. Rimuru Tempest is officially the strongest anime character ever.
