To be fair, there are plenty of reasons why this happens so often; side characters have the advantage of being a bit more mysterious than main characters, which allows audiences to project onto their actions and decisions. There’s also the fact that many side characters act as rivals, mentors, or even villains that oppose the main character and therefore require equally compelling motives and goals. As an avid main character defender myself, I can admit there have been plenty of times when I’ve fallen into the trap of eagerly awaiting the moment a supporting character appears on screen. So in this list, I’ll be exploring just a few of the side characters that certain fans will swear manage to take the spotlight without trying.
1) Levi Ackerman (Attack on Titan)

Levi Ackerman is easily one of the most iconic anime characters from the last decade, despite being part of Attack on Titan’s supporting cast. His first appearance is shown through Eren’s point of view, though he was later formally introduced as Captain Levi of the Survey Corps. Having grown up in the slums of the Underground City, Levi’s early life was characterized by struggle and survival until he was recruited by Erwin Smith to join the Corps.
In Attack on Titan, Levi is infamous for his strength and skill with ODM gear, making him a proficient Titan killer to the point Levi is dubbed “Humanity’s Strongest Soldier”. He is portrayed as having the most Titan kills in comparison to other characters, and notably tanks Zeke Yeager’s Beast Titan form numerous times on the battlefield with little difficulty. Levi’s popularity likely stems from his competence and the smooth animation of his fight scenes, causing him to stand out from the other Attack on Titan characters, including Eren Yeager.
2) Osamu Dazai (Bungo Stray Dogs)

Osamu Dazai is a perfect example of an anime character who knows more than the main character of their series, creating a sense of mystery and intrigue for the audience. Dazai is touted as a genius of sorts when it comes to manipulation, tactical planning, and predicting his enemies and allies alike. His “two-steps ahead” nature tends to drive the plot and give the Armed Detective Agency an advantage in most fights.
In Bungo Stray Dogs, Dazai is viewed as an incredibly useful asset by multiple sides, including the Port Mafia, ADA, and Fyodor Dostoevsky. This importance only makes Dazai more enthralling to watch when combined with the mystery of his past— we know Dazai was originally the youngest Port Mafia executive, but little else is known about his early childhood. His Ability, No Longer Human, nullifies other Abilities and again gives Dazai an advantage in fights against powerful threats. All of these factors tend to create an aura around Dazai that makes many fans want to see more of him on screen.
3) Roy Mustang (Fullmetal Alchemist: Brotherhood)

Roy Mustang is likely the lone Fullmetal Alchemist: Brotherhood character that is as recognizable as Edward Elric. Colonel Mustang is a State Alchemist, mentor to protagonist Edward, and a revered higher-up in the Amestrian State Military. His personality is often noted as egocentric, brash, and shallow, with a history of womanizing; while these observations aren’t entirely untrue, they’re used as a cover to hide Roy’s ambition to become the next leader of Amestris. Roy’s internal drive to bring justice and prosperity to his country after the last war lies at the core of his true goals and desires.
Colonel Mustang is able to adequately manipulate those around him to achieve his goals and further his plan to become the Fuhrer. Much of the show highlights Roy’s tactical brilliance and ability to flip the outcome in his favor. Not to mention, Roy’s talent for alchemy shines in the anime, specifically his mastery of fire-based combat, showcased in flashy yet efficient fight scenes that make him a fan favorite.
4) Saber (Fate)

Saber, or Artoria Pendragon, is one of the titular characters in Fate/stay Night and Fate/Zero. While Saber is considered a main heroine and an important figure in the show’s lore and plot, she is not actually the main character of either series— ironic, considering if you think of the series, you’ll likely picture marketing of Saber to promote the anime. Artoria has become one of the most predominant female anime characters in modern anime due to her intriguing backstory and characterization: she’s quite literally the legendary figure King Arthur.
During her lifetime, Saber served as the King of England for ten years until she met her demise at the betrayal of once-loyal knight Mordred. Artoria’s character is constantly plagued by regret and the guilt of failing to save her country, which is why she pledged to become a Servant and seek the Holy Grail. Saber wields Excalibur, an almighty sword that represents and heralds her Noble Phantasm. Heralded as the “King of Knights”, the complexity and significance of Saber’s character grant her the focus of audiences tuning in to the Fate series.
5) Satoru Gojo (Jujutsu Kaisen)

It’s probably no shock that Satoru Gojo is on this list. Gojo is another side character that’s visually linked to Jujutsu Kaisen just as much as the show’s protagonist, Itadori Yuji. The scale of Gojo’s power and prowess in fighting has earned him a special place in the hearts of many anime fans. There’s a reason he’s nicknamed the “Strongest Sorcerer” and the “Honored One” (self-dubbed, but still accurate nonetheless). You don’t have to like Gojo to admit he boosted Jujutsu Kaisen’s status among a wide field of shonen anime with his fight scenes alone.
Gojo’s birth into the anime’s jujutsu world setting heralded a new era of stronger curses to contest with the sheer strength of his cursed energy. He wields two separate Cursed Techniques: Limitless and the Six Eyes. One allows Gojo to intricately perceive the world around him, while the other grants Gojo the ability to manipulate infinity. As the strongest among his peers and one of the only Special Grade Sorcerers in Japan, Gojo’s place in the world of Jujutsu Kaisen is to protect the weak and teach the next generation of sorcerers.
