Regardless of the anime genre, many series often feature protagonists who start as underdogs but gradually become overpowered (OP) as the story progresses.
Initially struggling to keep pace with others around them, whether through rigorous training or unexpected turns of fate, these characters eventually evolve into powerful figures capable of overcoming formidable challenges.
These protagonists with dynamic growth arcs are highly relatable and often showcase some of the genre’s most compelling character developments. Whether set in fantasy realms, isekai adventures, sports competitions, or slice-of-life scenarios, these characters consistently exceed initial expectations.
Here’s a list of some top anime where the main character begins as weak but ultimately becomes OP.
7 Outstanding Anime Where the Initially Weak MC Transforms into an OP Powerhouse
Solo Leveling (Sung Jin Woo)
Sung Jin Woo’s transformation into an OP MC in Solo Leveling stems from a combination of fate’s twist and relentless effort. Initially depicted as an E Rank hunter, he languishes at the bottom of the hierarchy, earning the title of the “Weakest Hunter in History.”
However, Jin Woo’s fortune changes dramatically after he solves the “Statue of God” puzzle and meets his demise. Reborn retains his E rank magic levels but gains a new leveling system akin to a video game. This system boosts his base stats and skills by completing quests and missions.
Despite the appearance of a cheat-like skill, Jin Woo faces grueling challenges that push his limits. Yet, his unwavering determination and refusal to surrender are his greatest assets. Through perseverance, this once-feeble anime protagonist defies all obstacles to emerge as overwhelmingly powerful.
Black Clover (Asta)
Asta epitomizes resilience and determination. In a world where magic reigns supreme, the protagonist of Black Clover was born without any magical abilities. When all 15-year-olds were bestowed with their Grimoires, Asta received one with an Anti-magic devil sealed within its five-leaf clover.
Raised in a church after being abandoned, Asta’s childhood was marked by hardship, and his upbringing in the countryside brought further challenges once he joined the Magic Knights.
Due to his lack of magic and struggles with Anti-magic control, Asta often found himself as the weakest member of the Black Bulls. Despite numerous setbacks, he consistently picked himself up and maintained a positive outlook.
Asta doubled his efforts to master his powers, enduring rigorous training to become a dependable asset to his squad.
His rivalry with Yuno fueled his relentless pursuit of strength. As the story progressed, so did Asta’s resolve and physical prowess, propelling him to become one of the kingdom’s most formidable Knights.
Ranking of Kings (Bojji)
“The Ranking of Kings,” a standout anime of 2021, has been celebrated for its profound impact within the fantasy genre. Bojji’s journey, in particular, stands out as a testament to resilience and growth.
Bojji was born under a powerful curse due to his father Bosse’s pact with a demon. This curse left him deaf and physically weak, an initial handicap that could have embittered anyone. Yet, Bojji defied expectations.
He exhibited remarkable intelligence, empathy, and a keen awareness of his surroundings. Despite enduring harsh treatment, he maintained a cheerful demeanor.
In stark contrast to his half-brother Daida, Bojji’s character evolved steadily. He faced seemingly insurmountable challenges and grew stronger with each trial. From being perceived as the weakest anime MC, Bojji emerged as a hero who captured the hearts of many.
Gurren Lagan (Simon)
At the beginning of Gurren Lagann, Simon is portrayed as a timid and reserved boy. His journey starts alongside Kamina, whose influence gradually helps Simon gain confidence in his abilities.
Despite his initial timidity, Simon demonstrates a natural talent for combat from the outset. However, it is after Kamina’s death and his encounter with Nia that Simon undergoes a profound transformation.
Gradually, Simon’s self-assurance grows, bolstered by the support of his comrades, enabling him to confront the formidable Spiral King. From there, Simon’s growth becomes exponential.
Mastering the power of spiral energy, Simon transforms from a timid youth into a determined and confident young man when facing the ultimate cosmic adversary.
My Hero Academia (Izuku Midoriya)
Deku was born without Quirks, making him one of the rare individuals without special abilities. Despite this, he harbored a deep desire to become a hero and looked up to All Might, the number one hero of his time.
All Might pass on his One for All quirk through a fateful encounter with Midoriya. However, mastering these newfound powers proved to be a daunting challenge. Even at 5% to 10% of its full potential, using the quirk caused significant harm to Midoriya’s body.
Thus, not only did he struggle to control his abilities, but he also dedicated himself to rigorous physical training to withstand the strain. Deku relentlessly pursued his goal of becoming the ultimate hero, transforming from a powerless teenager into a compelling anime protagonist.
Tsukimichi: Moonlight Fantasy (Makoto Misumi)
Makoto’s journey in the new world as an Isekai protagonist started with misfortune. Initially whisked away by a Goddess due to a contract his parents signed, he faced immediate rejection due to his perceived lack of attractiveness, leaving him abandoned in a wasteland.
Fortunately, Makoto’s fate took a turn when he was rescued by the Moon God, Tsukuyomi, who felt responsible as the intermediary of the contract. Tsukuyomi bestowed upon him various blessings to aid the weak anime MC.
Despite his initial weakness, Makoto showed a natural talent for magic. Through rigorous training and occasional strokes of luck, he managed to recruit numerous powerful monsters to his side.
With each new servant, his magical abilities expanded, gradually transforming him into an overwhelmingly powerful figure.
Makoto relied on Draupnir rings to control his burgeoning strength, which absorbed and stored his excess magic, preventing it from overwhelming him or others around him.
Arifureta: From Common Place to World’s Strongest (Hajime Nagumo)
Starting off as the weakest member of the hero’s party in Arifureta, Nagumo faced constant rejection and bullying due to his “Synergist” job, considered the worst in the Isekai world, and his abysmal stats. His lowest point came when the Orcus Labyrinth collapsed during exploration, leaving him presumed dead.
Against all odds, Nagumo survived and thrived within the dungeon, transforming from a weak anime MC into an overwhelmingly powerful protagonist. His unyielding determination to survive drove his evolution. He began consuming monsters within the labyrinth, absorbing their powers through his “Synergist” abilities.
With each conquest, Nagumo grew stronger, but the dungeon’s challenges escalated in parallel. There were moments when he faced near-death situations, testing his resolve to its limits.
Yet, through sheer perseverance, Nagumo not only survived but surpassed the Hero and his party in strength, emerging as an indomitable force within the story of Arifureta.
