Top 15 Anime Sidekicks Way More Powerful Than The Hero

by

Sidekicks aren’t just for comic relief or carrying equipment. Often, they’re the heroes who win fights, save the main characters, and change the course of the story. Here’s a look at fifteen supporting characters who are consistently more capable, skilled, or impactful in battle than the leads, along with information about the creators who brought them to life.

Killua Zoldyck

Throughout much of ‘Hunter x Hunter’, Killua’s rigorous training as an assassin makes him faster, more skilled, and more perceptive than Gon. He even unlocks a technique called Godspeed, allowing him to move and react with incredible speed. Killua’s strategic thinking frequently saves Gon from dangerous situations. The 2011 anime adaptation by Madhouse highlights these differences in ability during key story arcs.

Mikasa Ackerman

Throughout much of the early part of ‘Attack on Titan’, Mikasa is a more skilled and effective fighter than Eren, consistently performing better in training and on the battlefield. She excels at taking down multiple enemies and protecting her team, and even as Eren grows stronger, she remains the most dependable close-combat soldier. Both Wit Studio and MAPPA consistently portray her as the best example of a Survey Corps member.

Saber

In ‘Fate/stay night’, Saber is a powerful heroic spirit, far stronger and more skilled than Shirou. While Shirou fights just to survive, Saber easily handles even the most powerful opponents. Her natural instincts, magical defenses, and incredible sword skills are often the deciding factors in battles, and would likely result in immediate defeat without her. The anime adaptation by Ufotable consistently emphasizes just how much more capable Saber is.

Alphonse Elric

In ‘Fullmetal Alchemist Brotherhood’, Alphonse’s metal body makes him tougher and more enduring than his brother Edward. He can perform complex alchemy without needing traditional circles, and he’s able to hold his own against powerful enemies for long periods. Alphonse also tends to stay calm under pressure, helping to de-escalate dangerous situations. Throughout the series, his unique abilities give him an edge in both one-on-one fights and larger battles.

Megumin

In the anime ‘Konosuba’, Megumin is incredibly powerful, able to destroy massive threats with a single, devastating explosion – a feat far beyond anything Kazuma can do. While using this spell completely drains her, the sheer amount of destruction it causes is unmatched within the group. She’s often the key to defeating major enemies and overcoming difficult obstacles with just one powerful attack. The animation studio, Deen, really emphasized how spectacular this ability was in the show’s earlier seasons.

Kallen Kozuki

Kallen is a powerful pilot in ‘Code Geass,’ turning her Knightmare Frames – particularly the Guren with its distinctive arm – into devastating weapons. She consistently defends Lelouch and breaks through enemy defenses while he directs the action from a safe location. Often, her individual combat skills are the deciding factor in battles that strategic planning alone can’t win. The animation studio Sunrise emphasizes her skill, showcasing her as a superior fighter.

Akatsuki

In the anime ‘Log Horizon’, Akatsuki acts as Shiroe’s main protector and handles secret missions he can’t do himself. She’s skilled at defeating tough enemies, exploring risky areas, and taking out targets accurately. Her character’s abilities focus on dealing a lot of damage quickly and controlling battles, which helps keep her team safe. The first season of the show quickly establishes this clear division of roles in combat.

Rem

In ‘Re:Zero,’ Rem is a powerful fighter who compensates for Subaru’s weaknesses. While Subaru focuses on strategy and talking, Rem handles the direct combat against dangerous enemies. Her unique heritage allows her to endure serious injuries and keep fighting, and the show clearly establishes her as a key frontline warrior during the most intense moments.

Arthur Boyle

In ‘Fire Force,’ Arthur is a powerful fighter whose plasma blade can slice through even the toughest enemies, often saving Shinra and his team. He quickly becomes stronger when the stakes are high, able to fight equally with powerful opponents like captains and pillars. Plus, his unique ability to focus actually makes him *more* effective when it matters most. The animation studio, David Production, really highlights his incredible cutting skills and fighting style during important battles.

Kohaku

Kohaku in ‘Dr. Stone’ is the team’s powerhouse, using her incredible speed, strength, and tracking skills to overcome physical challenges while Senku focuses on scientific solutions. She’s capable of defeating experienced fighters, moving large objects, and acting as the first line of defense for the group. Essentially, she protects both their inventions and their plans, and the animation studio, TMS Entertainment, portrays her as the Kingdom of Science’s protector and attacker.

Zenitsu Agatsuma

In ‘Demon Slayer,’ Zenitsu’s unique Thunder Breathing technique allows him to move incredibly fast, often surpassing Tanjiro in important fights. When fully focused, he can defeat demons before they even have a chance to respond. As he improves, he gains more techniques and becomes even more consistently faster. The animation studio, Ufotable, visually emphasizes this increase in power, showcasing how much stronger he’s become since the beginning of the series.

Rider Iskandar

As a huge fan of ‘Fate/Zero’, I’m always struck by how utterly dominant Rider is. He just crushes other powerful Servants with his sheer strength, incredible presence, and a truly amazing Noble Phantasm. Honestly, Waver is completely reliant on Rider’s power to get through each battle of the Holy Grail War. Every clever retreat and daring attack? It all comes down to Rider’s skill as a commander and the way Ufotable visually showcases that control – it’s just breathtaking to watch.

Raphtalia

In ‘The Rising of the Shield Hero,’ Raphtalia takes the lead in attacking, while Naofumi concentrates on protecting and assisting her. She’s a skilled swordswoman, easily defeating powerful monsters and enemies. As she gains experience and better gear, she helps keep their team strong enough to face increasingly difficult challenges. The anime studio, Kinema Citrus, clearly shows this teamwork and how each character contributes in every important fight.

Erza Scarlet

Erza from ‘Fairy Tail’ is incredibly versatile thanks to her ability to instantly change her armor and weapons, allowing her to effectively fight almost any enemy. She’s one of the strongest members of her guild and frequently saves the day when Natsu struggles. Her quick adaptability makes her especially useful in battles against multiple opponents or during long, drawn-out fights. The studio 1 Pictures consistently portrays her as the guild’s most reliable fighter to finish off opponents.

Sebastian Michaelis

As a big fan of ‘Black Butler’, what always strikes me is just how powerful Sebastian is. He’s a demon, so he’s way beyond anything Ciel could handle on his own. Seriously, he takes care of everything – assassins, monsters, you name it – with incredible speed and skill. He’s not just a fighter, though; he manages all the details, from gathering information to sneaking around, and makes sure everything runs smoothly. Honestly, the way 1 Pictures portrays him, he’s the ultimate problem-solver, and Ciel wouldn’t be able to achieve anything without him.
