Even incredibly powerful characters aren’t perfect and can still make mistakes. When someone has reached a high position, even a small error can have disastrous consequences. Whether it’s trusting the wrong person or underestimating an enemy, these missteps often lead to difficult and painful journeys.
Anime is full of powerful characters who stumble, and those missteps can derail their progress or even lead to their defeat. Even the most impressive characters can be undone by a single, critical error.
Goku Never Learns from His Mistakes in Dragon Ball
Goku is often considered one of the most mistake-prone heroes in anime, despite his incredible strength. A prime example is during the fight with Cell, when Goku foolishly gave Cell a healing bean, allowing him to recover and nearly defeat both Gohan and himself.
It seems like Goku doesn’t learn from his mistakes. He recently gave Moro a senzu bean in Dragon Ball Super, even though Moro immediately used it to continue fighting – a pattern Goku often repeats. He’s frequently shown mercy to his enemies, only for them to later become even more dangerous problems.
Edward Elric Almost Lost His Brother In Fullmetal Alchemist
In the anime Fullmetal Alchemist, Edward and Alphonse Elric attempted a dangerous act called human transmutation, which came at a great cost. After their mother, Trisha, died, Edward vowed to his brother that they would use alchemy to revive her. They dedicated themselves to rigorous training and developed a complex process to achieve this.
Unfortunately, the attempt went terribly wrong. Instead of reviving their mother, they created a horrifying, unliving collection of organs. As a result, Al completely lost his physical body, and Edward had to give up his right arm – in addition to already losing his leg – to rescue Al’s soul.
Lelouch’s Joke Cost Him a Massacre in Code Geass
In Code Geass, Lelouch accidentally caused a terrible tragedy with his powers. He unintentionally used his Geass on his half-sister, Euphemia, and lost control. All he’d done was playfully suggest to her that all Japanese people be eliminated, but the effect was devastating.
Lelouch’s Geass unexpectedly transformed a harmless comment into an unbreakable order. Unable to control the situation, Lelouch was forced to kill Euphemia to stop her from harming the very people she was trying to protect. The tragedy was especially heartbreaking because it could have been prevented.
Aura’s Overconfidence Led to Her Death In Frieren
In the anime Frieren: Beyond Journey’s End, Aura is a powerful member of the Seven Sages of Destruction, possessing magic far beyond what any ordinary person could imagine. Her unique ability allows her to compare her magical power to her opponents’; whoever has more mana gains complete control over the other’s body.
Aura, having lived for 500 years, was very confident in her magical power and believed she could defeat Frieren. She never suspected Frieren was secretly holding back her true power, using deception to hide its extent. This ultimately led to Aura’s defeat, as Frieren quickly overwhelmed her with a display of her full magical strength.
Demon Slayer’s Doma Paid the Price for His Reckless Bloodlust
Doma, a powerful and ruthless demon ranked second among the Upper Ranks in Demon Slayer, lived for decades. However, he never expected that simply eating a human would lead to his demise. During the Infinity Castle Arc, Doma defeated and ate Shinobu Kocho, the Insect Hashira, unaware that she had spent over a year poisoning her body with wisteria.
After absorbing Shinobu, Doma’s body started to weaken, greatly reducing his power. This gave Inosuke and Kanao the opening they needed to cut off his head. Ultimately, Doma’s arrogance and lack of foresight caused his defeat.
Zeke Severely Dared to Underestimate Levi’s Ruthlessness In Attack on Titan
Zeke Yeager was a brilliant strategist in Attack on Titan, but he underestimated Levi’s intense drive and ruthlessness. During the battle for Paradis, Zeke turned thirty of his fellow soldiers into mindless Titans as a way to escape. He mistakenly believed Levi wouldn’t kill his own team to pursue him.
Zeke was proven wrong when Levi quickly dealt with all the dangers. Levi destroyed the Beast Titan’s weak spot and extracted Zeke. Zeke underestimated Levi’s determination, and he could have avoided serious injury if he’d made sure Levi consumed the alcohol as well.
All For One Created the Quirk That Led to His Downfall In My Hero Academia
All For One inadvertently created his own downfall when he forcefully bestowed a quirk upon his younger brother. Driven by a warped form of affection and a desire for control, AFO didn’t realize his brother already possessed a power of his own.
All For One forcibly gave someone a quirk called Power Stock. This quirk then combined with the recipient’s existing quirk, creating One For All. This powerful quirk was later passed down to Deku and ultimately caused All For One’s defeat.
Madara Trusted the Wrong Broken Guy in Naruto Shippuden
Madara Uchiha is a remarkably powerful character in Naruto Shippuden, but his difficult life taught him not to trust anyone. He took advantage of Obito’s troubled past, hoping to turn him into a loyal soldier. However, Madara failed to see that Obito’s fragile mental state would ultimately be his downfall.
Obito quickly started a war, hoping to impose his idea of peace on the world, and became the host of the Ten-Tails, just as Madara had originally planned for himself. However, Obito soon lost his loyalty to Madara, which seriously disrupted Madara’s plans and caused significant delays.
Koro-Sensei was Backstabbed In Assassination Classroom
Before he became the teacher in Assassination Classroom, Koro-sensei was a legendary and terrifying assassin called The Reaper. He usually worked solo, but he once took on an apprentice, a decision he would later regret. That apprentice ultimately betrayed him, leading to his capture and transformation into the strange, powerful creature he is in the series.
If The Reaper hadn’t put any faith in his apprentice, he would have finished the assassination and none of the strange events of Assassination Classroom would have happened. It was the apprentice’s betrayal that started everything, ultimately leading to Koro-sensei becoming the teacher of Class 3-E and training them to be his assassins.
Jinwoo Sat Out of a Crucial Raid in Solo Leveling
In Solo Leveling, Jinwoo made a critical error that could haunt him forever. When his mother was finally healed from her long illness, he was overcome with emotion and chose not to participate in the Jeju Island Raid. Though he sent his shadow soldiers along with some hunters to receive updates, it wasn’t sufficient to prevent what happened.
The raid on Jeju Island was a terrible failure, resulting in many deaths. Several highly-ranked hunters, including the guild master Goto Ryuji, were killed. By the time Jinwoo arrived, the situation was already catastrophic. If Jinwoo had participated in the raid, many lives might have been saved.
