Here are some of the best anime where the mc is overpowered and surprises everyone
Protagonists come in all sizes and shapes, and many of them are incredibly (and sometimes annoyingly) overpowered. The main character may appear to be a regular person going about their daily activities, but they are capable of wielding enormous amounts of power.
Let’s look at some of the best anime with powerful main characters who have shocked the audience and everyone around them by revealing the magnitude of their power.
Best Anime Where MC Is OP And Surprises Everyone
23. Sky Wizard Academy

A long time ago, enormous magically armoured insects that had grown too powerful and hostile to handle nearly wiped out the entire human population. As a result of these enormous bugs, people now live in floating cities rather than on Earth. This, however, does not mean that all hope is lost, as these monsters are being fought by wizards from illustrious floating wizard institutions.
Kanata Age, once known as the “Black Master Swordsman,” is now regarded as a traitor. He has the potential to restore his reputation by guiding team E601, which appears to be having some issues. The three girls in it are Misora Whitale, Lecty Eisenach, and Rico Flamel, and they all have different problems. Kanata appears to have gotten herself into a lot of trouble as a result of them.
22. Cautious Hero: The Hero is Overpowered but Cautious

“You can never be too careful,” as the saying goes. Even if it appears to be a pointless waste of time, it is critical to be prepared for any situation that may arise. Furthermore, if you want to win completely in games like role-playing games, you should outclass your opponents.
These phrases almost perfectly characterise Seiya Ryuuguuin. After being summoned by the goddess Ristarte to save the planet Gaeabrande from annihilation, the hero prepares for his heroic adventure. Despite his extremely high stats, he spends a significant amount of time training himself, which may be normal. To stay safe, he employs his best weapons against weak opponents and amasses vast quantities of supplies and remedies.
Gaeabrande’s demeanour may be unpleasant, but it could be his saving grace in a world where evil powers rule over all expectations.
21. Yuuna and the Haunted Hot Springs

Yuragi-sou, formerly a hot springs inn and now a boarding house with ridiculously low rent, is nearly deserted except for a few strange occupants. It is said to be haunted by an evil ghost who scares away any potential occupants. Fuyuzora Kogarashi, a destitute and homeless psychic in need of a cheap place to stay and spirits to exorcise, will thus find it an ideal haven.
When Kogarashi is ready to confront the ghost, he discovers that it is not as evil as legend has it. It is the spirit of Yuuna, a lovely girl with silver hair whose only memory of her life before death is her name. Even more perplexing is the fact that each of the other Yuragi-sou residents, in addition to being able to see Yuuna, possesses a unique supernatural power.
In order to save Yuuna from becoming an evil spirit doomed to spend her afterlife in hell, Kogarashi searches for the sorrow that keeps her connected to the living world in the midst of the mayhem caused by his eccentric neighbours.
20. The Asterisk War

The Invertia, a remarkable disaster that occurred in the previous century, fundamentally altered the course of history. The Integrated Empire Foundation rose to power as a result of the world’s current states’ sharp decline in power. More importantly, the Invertia aided in the evolution of the Genestella, a new race of people born with extraordinary physical prowess. Its elite are hand-picked from all over the world to attend the top six schools, where they compete in shows called Festas.
Ayato Amagiri is a scholarship transfer student at the prestigious Seidoukan Academy, which has recently seen a decline in performance. He inadvertently spots Julis-Alexia von Riessfeld, the well-known Witch of Resplendent Flames, in her underwear! Julis is enraged and challenges him to a fight for invading her privacy. When the student council president cancels the duel, Ayato admits he has no interest in Festas. Instead, he enrolled in the academy in order to find his missing older sister. However, as a more devious plan emerges, Ayato sets out to triumph while surrounded by some of the world’s most talented Genestella.
19. Dr. Stone

Taiju Ooki, a high school student who has had feelings for Yuzuriha Ogawa for five years, is now ready to confess his feelings for her. However, just as Taiju begins to confess, the planet is engulfed in a bright green light, terrifying everyone on it and turning them all to stone.
When Taiju awakens a few millennia later, he discovers that the modern era has vanished and that nature has regenerated during the time when people were silent. In the stone world of statues, Taiju only encounters one other living person: his science-obsessed friend Senkuu, who has been active for a few months. Taiju discovers Senkuu’s ambitious plan to use science to bring civilization back to life. Taiju’s strength and Senkuu’s intelligence combine to form a powerful team that quickly discovers a way to resuscitate the petrified.
Senkuu’s grand scheme is jeopardised when his ideals are challenged by those who awaken. The cause of humanity’s petrification remains unknown.
18. Tanya the Evil

Tanya Degurechaff, a young soldier, has earned the moniker “Devil of the Rhine” for her predatorial ferocity and incredible tactical prowess. Underneath her innocent exterior, however, dwells the spirit of a man who challenged Being X, the self-proclaimed God, to a game of wits, resulting in his reincarnation as a young girl into a world of magical conflict. Tanya decides to rise through the ranks of her nation’s military as the world descends into conflict, with only Being X standing in her way of returning to the peaceful existence she once knew. The strong Empire’s astute moves and fighting initiative, on the other hand, have an unanticipated side effect that elevates it to one of the most powerful countries.
17. Classroom of The Elite

From the outside, Koudo Ikusei Senior High School appears to be a utopia. The students’ level of freedom is unparalleled, and it is highly regarded in Japan. The reality, on the other hand, is far from ideal. After being ranked in order of merit, only the top four classes—A through D—receive preferential treatment.
Kiyotaka Ayanokouji is in Class D, which houses the school’s worst students. There he meets the awkward Suzune Horikita, who wants to move all the way up to Class A because she believes she was mistakenly placed in Class D, and the friendly-looking class hero Kikyou Kushida, who wants to make as many friends as possible.
Class rankings are temporary, but class membership is; students in lower-ranked classes can move up if they outperform those in higher-ranked classes. Furthermore, there are no limits to how far one can advance in Class D. Is it possible to overcome the obstacles and succeed at this competitive school?
16. Isekai Cheat Magician

Taichi Nishimura, a regular high school student, is riding to school with his childhood friend Rin Azuma that morning. They are suddenly enveloped in a bright light that transports them to a fantastical planet teeming with supernatural beings.
When Taichi and Rin arrive, they are confronted by a beast. A group of explorers warns the two immediately after their rescue that going unarmed and untrained exposes them to the recently on the rise monster attacks. Taichi and Rin are directed to the Guild in order to register as adventurers and determine their magical aptitude. The test they take, however, produces an unexpected result: Taichi and Rin have extraordinary abilities that far exceed those of a traditional mage, quickly elevating them from ordinary high school students to the pinnacle of cheat magicians.
Taichi and Rin gain a thorough understanding of their abilities while also adjusting to their new surroundings. However, an unexpected threat lurks in the shadows as the pair attempts to determine the cause of their transportation and a possible route back to their home world.

The abolition of a vampire that is turning Cheddar’s residents into ghouls necessitates the assistance of Hellsing, a group that specialises in combating supernatural threats. The organization’s leader, Sir Integra Fairbrook Wingates Hellsing, dispatches her most formidable asset, a powerful vampire named Alucard, to put an end to this.
With only a single firearm, Alucard unleashes hell on the demons that plague Cheddar. Seras Victoria, a young police officer, is killed as a result of his involvement in the chaos. Alucard, who cares about the girl, gives her the option of remaining a vampire or dying as a human. Seras accepts his invitation and begins a new life as a Hellsing.

The strange continent is home to long-dead soldiers from various periods of Toyohisa’s history, as well as several fanciful creatures. Toyohisa learns about the continent’s political strife as soon as he meets the notorious warlord Nobunaga Oda and the legendary archer Yoichi Suketaka Nasu.

Melromarc is a nation that has been repeatedly destroyed by the Waves of Catastrophe, which have wreaked havoc on its people for centuries. To defeat the Waves, each of the four heroes is given a sword, spear, bow, and shield. The curse of being the “Shield Hero” falls on Otaku Naofumi Iwatani.

In contrast to Yuno, who can use magic with incredible power and control, Asta is unable to use magic at all and is desperately trying to develop his abilities through physical training.
When they reach the age of 15, Asta receives nothing, whereas Yuno receives a magnificent Grimoire adorned with a four-leaf clover. Soon after, however, a man named Lebuty attacks Yuno with the intent of stealing his Grimoire. Lebuty is more powerful than Asta, who attempts to fight him.

When he reincarnates two millennia later, he is astounded to find that the amount of magic in the world has decreased significantly. When he enrols in the academy to reclaim his rightful rank, he discovers that demonkind has a different memory of him.
