6 Surprisingly Powerful Anime Characters Who Defy Their Appearance

In the realm of anime, first impressions can be misleading. Characters may present as weak or harmless at first glance, but they often harbor remarkable strength beneath their seemingly fragile exteriors. This disparity can arise from their latent abilities, exceptional combat skills, or sheer determination, demonstrating that genuine power frequently lies hidden.
Across various anime series, many protagonists and supporting characters disguise their formidable strengths behind ordinary façades. Below are six anime characters who are far more powerful than they initially appear.
6. Different
My Hero Academia
Eri may initially seem like a frightened little girl, characterized by her timid demeanor and soft-spoken nature. However, beneath her delicate surface lies the potential for extraordinary power. Her Quirk, known as “Rewind, ”enables her to revert a person’s body to a previous state, thus healing injuries, reversing aging, and potentially erasing individuals altogether if she loses control. While she lacks traditional combat abilities, her potential could position her as one of the strongest characters in My Hero Academia.
During the intense showdown against Overhaul, Eri’s abilities were showcased as she helped Deku by continuously healing his injuries, allowing him to fight at maximum capacity without sustaining harm. This revelation not only highlighted her immense capabilities but also underscored the precarious nature of her gift—should she lose control, the consequences could be catastrophic.
Despite her godlike powers, Eri’s biggest challenge is mastering her abilities. She remains a child, grappling with the immense strength she possesses but does not yet understand.
5. Escanor
The Seven Deadly Sins
At first glance, Escanor might be mistaken for an unassuming bartender with a shy demeanor, not someone designated as one of the mightiest characters in The Seven Deadly Sins. His true potential is unveiled with the rise of the sun, which amplifies his strength exponentially; by noon, he becomes an invincible powerhouse.
His unique ability, Grace of Sunshine, allows him to gain power throughout the day, culminating in a form where he stands as a colossal figure of pride and confidence. In his notable clash against Estarossa, a formidable demon, Escanor demonstrated not only his might but also his disdain for minor threats, effortlessly taunting his foe.
However, there’s a tragic irony to Escanor’s strength—using his abilities inflicts damage on his own body and ultimately shortens his lifespan. This duality renders him both the strongest under sunlight and a fragile being in its absence.
4. Magic Buu
Dragon Ball Z
Majin Buu’s chubby, pink exterior and childish disposition make him appear more like a whimsical character than a formidable threat capable of annihilating planets. His seemingly innocuous nature led many, including Mr. Satan, to underestimate him.
Buu’s regenerative capabilities make him a nearly unbeatable opponent, as he can recover from the smallest particle of his being. His various transformations, from Fat Buu to Super Buu and finally Kid Buu, reveal an escalating danger that belies his outward appearance. The smallest form, Kid Buu, is, ironically, the most destructive, showcasing the theme of looks being deceiving in the series.
Even Goku, typically a problem-solver, required aid from the entire universe—through the Spirit Bomb—to finally conquer this deceptively innocent character.
3. Choji Akimichi
Naruto
Often regarded as the underdog, Choji Akimichi is frequently underestimated by peers in the Hidden Leaf Village. His love for food and soft appearance contribute to an image of someone incapable of holding his own in a fight. However, Choji showcases incredible strength when he fully unleashes his abilities.
As a member of the Akimichi clan, he utilizes the Multi-Size Jutsu to enlarge his body, significantly boosting his power output. His strongest form, Butterfly Mode, allows him to convert body fat into strength for an unprecedented increase in combat ability.
During the Fourth Great Ninja War, Choji’s defining moment came when he battled the Reanimated Asuma, dispelling years of doubt and revealing the true depth of his power. The only barrier he faced was his self-perception; when he fights with conviction, he becomes a considerable force on the battlefield.
2. Selim Bradley
Fullmetal Alchemist: Brotherhood
In Fullmetal Alchemist: Brotherhood, Selim Bradley initially appears to be an affable and charming boy, the innocent son of Fuhrer King Bradley. His youthful charm conceals a much darker truth: he is, in fact, Pride, the first and most powerful of the homunculi.
His shadows are not merely for decoration; they are lethal weapons capable of slicing through steel. The revelation of his true identity transforms earlier innocent scenes, unraveling the sinister reality of his interactions. His supposed childlike fears of the dark are merely a facade, as darkness only enhances his shadowy powers.
The tension escalates throughout the series as characters gradually realize they have been conversing with a monstrous entity that has existed for centuries, leaving a haunting impact on their encounters.
1. Saitama
One Punch Man
Saitama embodies the epitome of “average.” With his bald head, simple costume, and perpetually bored expression, he stands in stark contrast to the more dramatic heroes around him in One Punch Man. Yet, his appearance belies an unparalleled strength that renders him virtually invincible.
His relentless training broke the limits of physical capability, allowing him to achieve a level of power that diminishes the meaning of every battle. A single serious punch from Saitama can obliterate mountains and end conflicts in a heartbeat.
The climax of his power is poignantly illustrated in his fight against Boros, an extraterrestrial who deemed himself unbeatable. After Boros unleashed his might, Saitama concluded the confrontation effortlessly, leaving devastation in his wake.
Ultimately, Saitama’s greatest challenge lies not in defeating foes, but in finding a worthy opponent. His strength has left him in a state of ennui, where no fight seems to spark excitement or truly challenge him, making him an unsettling yet incredibly powerful hero.
