In the world of anime, some characters shine so brightly they overshadow the main cast. Even if they only appear as support or rivals, their deep backstories, unique ambitions, and strong presence make fans crave spin-offs focused solely on them.
A spin-off series is not only a tribute to these characters but also a chance for creators to explore hidden corners of the story’s universe that the main plot can’t pause to reveal. Here are 10 characters who would definitely make a huge impact if they had their own series.
10. Levi Ackerman (Attack on Titan)
Although Levi already has the No Regrets spin-off, it’s still not enough for the “strongest soldier humanity has ever known.” A dedicated series set during the early days of the Scout Regiment, filled with brutal missions that the main story never touched on, would be perfect.
The appeal wouldn’t just be in the thrilling Titan battles but in the weight of harsh decisions where even Levi’s skills can’t save his comrades.
9. Itachi Uchiha (Naruto)
Itachi’s life is a perfect political tragedy. A spin-off could follow him from his days as a prodigy, through his time in ANBU, to the climax of the Uchiha clan’s conflict with the Leaf Village.
Viewers would witness how his choices slowly erode under pressure from corrupt institutions and bitter “greater good” decisions that feel like poison.
8. Nobara Kugisaki (Jujutsu Kaisen)
Nobara’s attitude and fighting style could carry a stylish action series on their own. Her “Resonance” technique fits perfectly with urban investigations, folklore rumors, and tactical battles.
This series would shine by exploring the clash between her rural roots and the harsh realities of Tokyo, where Nobara fiercely maintains her uncompromising spirit.
7. Yoruichi Shihōin (Bleach)
Yoruichi has everything a spin-off needs: noble status, a dark past, and deep ties to Soul Society’s intelligence network. A story about her leaving the Shihōin clan or her secret missions with the Stealth Force could become a top-tier spy thriller.
This would also give Bleach a chance to sharply explore the rigid class system and the strict Central 46 Court.
6. L Lawliet (Death Note)
L could lead a long-running detective series featuring complex international cases. Before his battle with Kira, he was already a world-renowned investigator.
Fans would love seeing how he uses logic, probability, and psychological pressure to catch criminals while casually enjoying sweets and displaying his quirky habits.
5. Roy Mustang (Fullmetal Alchemist)
Mustang’s rise through the military is filled with ethical compromises and political ambition. A series about him would reveal the cost of changing the system from within.
The tension between loyalty and the trauma of the Ishval war would provide rich material for a deep, dramatic show.
4. Killua Zoldyck (Hunter x Hunter)
This would be the best way to explore the mysterious assassin world of the Zoldyck family. Killua’s story blends intense action with his psychological recovery after years of torture-based training.
Watching Killua learn to set boundaries, develop loyalty, and build his own moral compass after escaping his family’s control would be an emotional journey.
3. Gojo Satoru (Jujutsu Kaisen)
Although parts of Gojo’s past have been revealed, much about the fractured modern Jujutsu world remains a mystery. The heart of this series wouldn’t just be his unmatched power but the loneliness of standing at the top.
Seeing Gojo’s efforts to build a future through education and reform would add deeper meaning beyond just flashy battles.
2. Erza Scarlet (Fairy Tail)
Erza could take Fairy Tail in a new direction, focusing on missions and character growth instead of chaotic battles. Her past at the Tower of Heaven, sense of responsibility, and ever-changing arsenal make her perfect for solo adventures where she faces choices between compassion and vengeance.
1. Vegeta (Dragon Ball)
Vegeta has the richest character development in the entire Dragon Ball franchise. A spin-off focusing on his early years as the Saiyan prince under Frieza’s shadow, the fall of Planet Vegeta, and the psychological scars of serving an enemy would be a tragic and powerful prequel.
From ruthless villain to Earth’s protector, Vegeta deserves his own stage to cement his legacy.
