Bleach introduced Unohana as the calm and composed Captain of the 4th Division, while Kenpachi was the wild and battle-hungry Captain of the 11th. Their connection was hinted at but never fully explored until the Thousand-Year Blood War arc. When their long-awaited battle finally happened, it revealed Unohana’s true identity as the original Kenpachi, a ruthless warrior who once reveled in battle. However, her role in the story was brief, as she sacrificed herself to help Kenpachi unlock his full potential.
While Retsu Unohana’s death was significant in shaping Kenpachi’s growth, it felt unfair to her character. She was built up as one of the most powerful fighters in Soul Society, yet she was only given a single fight before being removed from the story. Her farewell felt like a tool to boost Kenpachi, rather than a satisfying conclusion to her own journey.

Unohana’s Wasted Potential As A Fighter

From the very beginning of Bleach, Unohana was portrayed as a mysterious figure. Despite being one of the oldest and most respected Captains, she was almost never seen in combat. Her reputation was built on her healing abilities rather than her strength, leading many fans to believe she was simply a support character.
However, when it was revealed that she was the original Kenpachi - the strongest warrior of her era, it completely changed how we saw her. Unohana wasn’t just a healer; she was a monster in battle, someone even Kenpachi admired as a child. Her powerful Zanpakuto and Bankai, Minazuki, showed just how terrifying she was, yet we only got a glimpse of her full strength. After a single fight, she was gone, and the opportunity to see her truly shine was lost.
Was Her Sacrifice Necessary For Kenpachi?

Kenpachi’s character arc has always been about his love for battle and his search for stronger opponents. He had fought some of the most powerful enemies in Bleach, but he was always holding himself back due to an unconscious mental block. Unohana’s role was to help him break through that limit and unlock his true potential.
While her sacrifice did achieve this goal, it raises the question; was there no other way? Unohana’s battle could have been a turning point in Kenpachi’s journey without requiring her death. She could have continued as a great mentor, training him for the upcoming battles instead of being discarded so quickly. Her sacrifice felt like a rushed way to power up Kenpachi, rather than a meaningful resolution to her own story.
Unohana Deserved More Screen Time In Bleach

For a character as important as Retsu Unohana, her role in Bleach was surprisingly small. She had been in the series since the early arcs, yet she remained in the background for most of the story. It wasn’t until the Thousand-Year Blood War arc that we learned about her past, and by then, it was too late to truly explore her character.
Her death meant we never got to see her fight against the Sternritter or interact with other powerful Captains like Yamamoto, Shunsui, or Urahara. Even her relationship with Kenpachi was barely developed before their final battle. With her incredible strength and experience, she could have played a major role in Soul Society’s war, but instead, she was removed right after her reveal.
Final Verdict: A Great Character Left Unshined

Unohana’s death was one of the most impactful moments in Bleach, but it wasn’t the sendoff she deserved. While her sacrifice did help Kenpachi grow, it felt like a wasted opportunity to develop her as a character. She had the potential to be one of the strongest warriors in Soul Society, yet she was only given a brief moment to shine before being written out.
If Unohana had been given more screen time, her farewell would have been more meaningful. Instead, her death felt more like a tool to boost Kenpachi rather than a proper conclusion to her own story. Bleach fans will always wonder what could have been if Retsu Unohana had been allowed to truly unleash her full potential.
