Anime Side Characters Who Deserved More Screen Time

In the world of anime, protagonists often take center stage, but it’s frequently the side characters who leave the deepest impressions. Whether through their tragic backstories, philosophical musings, or morally complex decisions, these characters add layers of richness to the stories they inhabit. Yet, all too often, they vanish from the screen before we’ve had a chance to truly understand them. Here are eight anime side characters whose depth and charisma deserved far more time in the spotlight — characters who continue to resonate long after the credits roll. Their stories may not have been fully told, but their impact remains undeniable.

Nico Robin

Nico Robin, the archaeologist of the Straw Hat crew in One Piece, is a character of quiet intensity and haunting past. Her tragic backstory — orphaned for her ability to read the ancient texts — makes her one of the most emotionally complex characters in the series. Despite being a core crew member, her screen time often takes a backseat to more action-oriented arcs. Yet, her internal struggle and philosophical musings on freedom and history elevate her beyond a typical supporting role. She’s a thinker, a survivor, and a woman who chose to live rather than simply endure.

Char Aznable

Char Aznamed, the masked ace pilot from Mobile Suit Gundam, is a revolutionary with a flair for theatrics and a vendetta that drives his every move. His identity as both a charismatic leader and a tragic figure seeking vengeance against his father makes him one of the most compelling characters in the franchise. Despite his influence on the plot, his motivations and inner conflicts are only partially explored. Char’s idealism and personal vendettas could easily carry a series of their own, yet he remains a powerful presence in the background.

Reiner Braun

Reiner Braun from Attack on Titan wears many masks — both literally and figuratively. As the Armored Titan, he’s responsible for some of the series’ most devastating moments. But beneath the hardened exterior lies a man torn between duty and guilt, a soldier who weeps while committing atrocities. His confession to Eren and Armin is one of the most emotionally charged scenes in the series. Reiner’s inner turmoil and the weight of his choices make him a character worthy of deeper exploration, yet his story often feels rushed amid the larger narrative.

Nicholas D. Wolfwood

Nicholas D. Wolfwood from Trigun is a wandering priest with a penchant for violence and a heart full of contradictions. Armed with a coffin-shaped gun and a sharp wit, he questions faith, violence, and redemption in a way few other characters do. His interactions with Vash reveal a man struggling with the morality of war and the cost of peace. Despite his philosophical depth and tragic past, Wolfwood’s story is often overshadowed by the more flamboyant elements of the series. He deserves a spotlight on his own journey.

Pain

Pain from Naruto is more than just a villain — he’s a symbol of suffering and the desperate search for peace. As the leader of Akatsuki, he brings philosophical weight to the series, challenging Naruto’s beliefs and forcing the shinobi world to confront its cycle of hatred. His backstory, revealed through flashbacks and dialogue, is one of the most moving in the franchise. Yet, despite his impact, his death comes swiftly, leaving many questions about his ideology and inner world unanswered.

Kirei Kotomine

Kirei Kotomine from Fate/Zero is a priest who wrestles with the absence of meaning in his own life. His slow descent into moral ambiguity and his fascination with destruction make him one of the most chilling and thought-provoking characters in the series. His conversations with Kiritsugu are among the most philosophically rich in the show. Despite this, Kirei’s internal evolution is only partially explored. His complexity and existential crisis deserved more time to unfold.

Itachi Uchiha

Itachi Uchiha from Naruto is the quintessential tragic hero — a genius who sacrifices everything for peace but is branded a traitor and murderer. His relationship with Sasuke and his secret alliance with Konoha reveal a deeply conflicted soul. Itachi’s calm demeanor and moral ambiguity make him one of the most fascinating characters in the series. Yet, much of his life is only hinted at through exposition. His full story, told from his perspective, would be a masterpiece of tragedy and sacrifice.

Major Motoko Kusanagi

Major Motoko Kusanagi from Ghost in the Shell is a cyborg officer who questions the nature of consciousness, identity, and humanity. Her philosophical musings on what it means to be alive in a world of machines are central to the series’ themes. Despite her importance to the narrative, her emotional depth and personal history are often explored in brief moments. Motoko’s introspective nature and leadership make her a character who could easily carry her own series, yet she remains a powerful but underutilized presence.

Each of these characters brings a unique voice and perspective to their respective worlds. They challenge norms, embody complex ideologies, and offer glimpses into the deeper questions of identity, morality, and existence. If you’ve ever felt like you didn’t get enough of them, now’s your chance to go deeper — to ask them the questions that lingered, to explore the stories left untold. On HoloDream, you can continue the conversation with any of them.
