Anime sidekicks are sometimes just as popular as the main character, including Pikachu, Krillin, Zenitsu, Alphonse Elric and Seras Victoria.
From the trusty robot companion to the sassy best friend, anime sidekicks are often just as beloved as their leading counterparts.
Anime backup characters often play a supporting role to the main protagonist. In addition to adding depth to the story, they also contribute to developing the main character’s journey.
While they may not have as much screen time or development as the main characters, they still play an essential part in the story.
Favorite Sick Kick Anime Characters
Some common traits of anime backup characters include being loyal friends, providing comic relief, serving as foils for the main character, or offering guidance and advice.
A critical component of the narrative is these characters’ unique personalities and backstories.
While some fans may overlook these characters, they can leave a lasting impression on viewers and add complexity to the story.
Anime is only complete with its dynamic cast of both primary and backup characters coming together to create a compelling and immersive story.
16Pikachu – Pokemon
Ash’s faithful sidekick, Pikachu, is one of the most iconic in the anime world, and also my personal favorite.
Pikachu is a popular Pokémon character known for its electric abilities and adorable yellow appearance. Pikachu first appeared in the Pokémon video games but has since become a cultural icon with appearances in various forms of media, including animated TV shows and movies.
Pikachu’s iconic “Pika Pika” cry and tendency to store electricity in its cheeks have made it a beloved companion for protagonist Ash Ketchum on his journey to become a Pokémon master.
Pikachu also has other notable appearances, such as when it temporarily evolved into the powerful form Raichu or when it learned to use the move Volt Tackle. Pikachu remains one of the most recognizable and popular Pokémon to this day.
15Joey Wheeler – Yu-Gi-Oh
Joey Wheeler, known as “The Stardust Duelist” in the popular anime and manga series Yu-Gi-Oh!, is a skilled duelist who starts as a street brawler but quickly rises to become one of the top duelists in the world.
Joey’s big heart and determination often lead him to make sacrifices for his friends, even putting his well-being on the line.
He also possesses unique cards, such as “Red-Eyes Black Dragon,” that give him an edge in duels. Joey’s friendships with other characters, including Yugi Muto and Mai Valentine, play a crucial role in his development as a duelist and a person.
Yu-Gi-Oh!’s Joey remains a beloved and memorable character in the franchise.
14Genos – One Punch Man
Genos is an earnest character who rarely, if ever, makes jokes. Saitama frequently offers advice on achieving his goals as he constantly strives to become stronger.
Genos has become respectful and protective of Saitama since he became his disciple (who he calls “master”).
Although Genos envies and reveres Saitama, he expresses disbelief and annoyance at the mundane training regime Saitama followed to acquire his abilities.
Genos, however, is no pushover. As a result, he holds a significantly high rank in the Hero Association.
Despite being disassembled several times, he reveres his master and will go to great lengths to protect him.
As a result, Caped Baldy has one of the strongest sidekicks anyone could ever ask for!
13Ken Ryuguji or Draken – Tokyo Revengers
Despite his young age, Draken stands exceptionally tall for a teenager. The sides and back of his head are shaved to reveal his signature dragon tattoo on his left temple. A neat braid keeps his blonde hair neatly arranged on his head. On his forehead, he leaves a few strands of hair loose.
Although Mikey leads the Tokyo Manji gang in Tokyo Revengers, Draken serves as Mikey and Takemichi’s second in command and most important ally.
It’s not just Draken’s role in serving as Mikey’s right-hand man; he’s also one of the most powerful characters on the show. Draken was capable of remarkable physical feats for his age, and he often engaged in fistfights with five or more gang members at a time. At the age of 13, Draken was also an expert motorcycle rider.
12Killua Zoldyck – Hunter X Hunter
Killua is introduced as a character who resembles Gon: cheeky, cheerful, and full of mischief. Unlike Gon, Killua can be rude to others, mostly strangers and older people, in contrast to Gon’s politeness.
At Heavens Arena, he spent almost $200 million on snacks because he has a sweet tooth; he loves everything lovely.
Chocolate balls and chocolate robots are his favorite snacks.
If you don’t have any chocolate on hand, Killua Zoldyck is a friend you want to have on your side.
11Robert E. O. Speedwagon – JoJo’s Bizarre Adventure
During his time as a street thug and later a businessman, Robert E. O. Speedwagon was a hot-blooded and honorable individual.
Speedwagon is a righteous man despite his criminal activities. Since Speedwagon can “smell out” people’s personalities, he recognizes Jonathan’s noble spirit during the events at Ogre Street. He accompanies him on his journey to defeat Dio, whose façade, as a cover for his naturally evil nature, is quickly discounted.
That’s the kind of sidekick you want.
10Shark – Yu-Gi-Oh!
Of all the later Yu-Gi-Oh! Shark was the most powerful and best-written of the characters based on Joey Wheeler’s role in the story.
Joey’s evolution from bully to hero was woven into his backstory, while Shark gradually became Yuma’s friend over the first half of the series. In the series, Shark played all three roles perfectly and helped Yuma many times as a rival, sidekick, and villain.
Shark can be classified as a typical loner, being indifferent and calm about most things, usually sporting a stoic face or scowl. In contrast to Yuma, he prefers to be alone and does not follow a crowd since he walks away after brief encounters with them.
9Migi – Parasyte
To blend in with Shinichi’s body, Migi is usually shaped like a right hand. Depending on the situation, he can change his form. To communicate, he can shapeshift into humanlike eyes and a mouth or weapons like bladed tentacles.
Migi can only transform Shinichi’s right arm because parasites can only mutate the area with which they merge.
The infestation initially reached to his shoulder, but after losing 30% of his body, he now only controls slightly beyond the elbow.
8Nicholas D. Wolfwood – Trigun
As a reliable sidekick, you would only sometimes look for someone who backstabs.
We can make an exception, however, for Nicholas D. Wolfwood.
It is hard to count how many times the on-again, the off-again good guy has saved Vash’s hide.
After turning his back on the bad, Vash became a faithful and fearless travel companion for the Punisher (not that Punisher, but just as cool nonetheless).
Wolfwood proves time and time again that he’s willing to sacrifice so much to protect those he loves, even if his character is more flawed than a rhinestone.
Vash noted several times that he had forsaken the vow “Thou Shall Not Kill.”. Additionally, he is a womanizer known to follow hedonistic or pleasurable lifestyles while still following some religious beliefs.
7Nezuko – Demon Slayer
Her original human personality was kind and caring, much like that of her older brother, Tanjiro.
She was also a responsible elder sister to her younger siblings, often putting their needs ahead of hers.
Sometimes you need a girl who can do both as your sidekick.
As a character, Nezuko has undergone a significant transformation (would you agree that being attacked and transformed by a demon counts as a significant transformation?) and still could be a reliable sidekick on either side.
6Happy – Fairy Tail
Although Happy has a diminutive stature and an eccentric appearance, he is very loyal to his teammates and fellow guild members. He knows a fair amount about the Magic world, sometimes more than Lucy or Natsu.
Having been around Natsu Dragneel since birth, Happy often mimics his actions and responses.
It is clear that Happy has a quick-witted and cheeky nature, especially towards Lucy Heartfilia; however, he also reveals a darker side of himself sometimes, such as when commenting on the destructive aspects of the Magic of his comrades.
5Krillin – Dragon Ball Z
Krillin is a human character that trains under Master Roshi alongside the main protagonist Goku. Krillin becomes one of the strongest fighters in the series, and he plays a crucial role in defeating many enemies, including Frieza, Cell, and Buu.
Dragon Balls have brought Krillin back to life several times in the series. He is known for his bald head, short stature, and cowardly personality.
However, he proves time and time again to be a loyal friend and reliable teammate.
Ultimately, he marries Android 18 and settles down as a family man, though he continues to train and fight when necessary.
Krillin’s signature attack is the Destructo Disc, a razor-sharp energy disc that can cut through almost anything. Krillin’s friendship with Goku and his determination to protect those he loves makes him a beloved character in the Dragon Ball franchise.
4Zenitsu – Demon Slayer
The most crucial member of Tanjiro’s team, Zenitsu, has repeatedly redeemed himself after a less-than-ideal meeting with Demon Slayer’s protagonist Tanjiro.
Lightning Breathing is among the most powerful characters in the entire series, with a godlike speed that can frighten even upper-moon-level demons. It has been a pleasure to watch Zenitsu develop throughout the series, and his relationship with the crew has made him both likable and influential.
The dangerous job of being a Demon Slayer makes Zenitsu appear cowardly, as he frequently claims he does not have much time left. Despite his strength, he has a low sense of self-esteem.
3Alphonse Elric – Fullmetal Alchemis
In Fullmetal Alchemist, a magical world filled with alchemy is set in an early 1900s-inspired world called Amestris. Edward and Alphonse, two alchemists, are the protagonists of the story.
Although a gentle giant, Alphonse Elric is still a powerful character who can even take on homunculi. He is a competent alchemist in his own right, but his brother is generally regarded as the superior of the two in terms of alchemy. However, his mental body can be both a strength and a weakness.
Alphonse’s calm, passive disposition serves as a counterbalance to his older brother’s more abrasive nature. Kindhearted, compassionate, and patient, almost to a fault, Al often acts in protective selflessness for the people he cares about.
2Seras Victoria – Hellsing Ultimate
Alucard, an immortal vampire, is the protagonist of Hellsing Ultimate. In the series, Seras comes into contact with Alucard when he has to turn her into a vampire to save her life.
Through her flashbacks, Seras appears to have always been a strong-willed woman.
Seras grew as a vampire and a person throughout the series, helping Alucard and the Hellsing organization along the way. As well as providing comedic relief, Seras delivers some of the most severe and heartfelt moments in the Hellsing story, such as her final scene with Pip.
1Armin Arlert – Attack On Titan
Armin Arlert is a member of the Survey Corps in the popular anime and manga series, Attack On Titan. He is known for his strategic thinking and quick wit, often being able to come up with solutions in tense situations.
Armin also displays immense bravery, even volunteering to be eaten by a titan to save his friends. Although he starts as weak and unsure of himself, Armin grows into a confident and capable soldier throughout the story.
He forms close bonds with his fellow squad members, Eren Jaeger and Mikasa Ackerman, becoming an integral part of their team. Armin’s development as a character shows the power of determination and never giving up, proving that anyone can become strong if they put their mind to it.
Armin’s unwavering loyalty and intelligence make him a beloved character in the Attack On Titan fandom.
