There is nothing like watching an incredibly powerful hero destroy everything in their path in anime. These known fantasy anime OP MCs are completely different, whether through outrageous supernatural powers, genius intellects, supreme talents or just sheer willpower. These OP MCs will amaze you with how much power and hype they bring to their series.
The Classics
Son Goku (Dragon Ball Series)
The OG OP MC that redefined expectations. Goku’s power levels and iconic abilities make him the gold standard against which all other anime characters are compared.
Alucard (Hellsing Ultimate)
This harrowing, gruesomely powerful vampire warrior and his aversion to violence makes him one of the most overrated anime antiheroes.
Guts (Berserk)
Known for his brutal swordsmanship and unmatched strength, Guts leads a path of absolute destruction throughout this dark fantasy world.
Saitama (One Punch Man)
The idea of being overpowered is played for laughs with Saitama, who literally knocks out every fight with One punch. It’s hilarious watching him basically ruin his own show.
Frieren (Frieren: Beyond Journey’s End)
Frieren is a new contender on this list but that doesn’t mean she’s not as strong as the others. She’s over a thousand years old and is one of the strongest beings in her verse. She is still capable of producing a black hole without even running out of mana.
Shonen Powerhouses
Naruto Uzumaki (Naruto)
Starting as an outcast, Naruto develops into probably the most ruthless ninja in history through sheer will and determination, resulting in wildly OP skills like the Rasen-Shuriken.
Gon Freecs (Hunter x Hunter)
A fairly ordinary kid at first, Gon rapidly develops over the course of the series into a ridiculously powerful, beast of a fighter once he gets going.
Asta (Black Clover)
Asta begins with nothing but pure magic powers, making his eventual transformation to unbelievable levels of strength and skill all the more inspiring to watch unfold.
Sung Jin Woo (Solo Leveling)
Although Solo Leveling just released, Sung Jin Woo is without a doubt going to become one of the most overpowered MCs in Shounen. He has the ability to literally create shadow soldiers, is faster than the human eye can see, and will become so strong he’s essentially a GOD.
Shigeo “Mob” Kageyama (Mob Psycho 100)
Hidden from society by his godlike psychic powers, he tries to live normal life until he reaches 100% and unleashes the devastation—an interesting character study.
Overpowered In Isekai Anime
Anos Voldigoad (The Misfit of Demon King Academy)
Reincarnated as The insanely powerful Demon King of Tyranny himself, Anos first tries to hide his powers in The present day before letting them rip.
Rimuru Tempest (That Time I Was Reincarnated as a Slime) 
Reborn as a slime monster with wildly OP abilities, Rimuru tests his newly acquired powers in this isekai adventure.
Ainz Ooal Gown (Overlord)
Another powerful wizard was trapped in his old online game. Ainz Ooal Gown, with its spells, items, and abilities, makes him a power unlike any other.
Kazuto “Kirito” Kirigaya (Sword Art Online)
After being enslaved in the virtual world of Sword Art Online, Kirito became its most prestigious and ace player nobody else can match.
Conclusion
Whether born to rule, intensely trained, teleported to new worlds, or empowered by demons, these fantasy anime OP MCs possess absurd power. Be warned: watching their feats and abilities in action may just break your brain!
