Bleach's Thousand-Year Blood War Arc delivered one of its most shocking moments when Yhwach bypassed the obviously talented Bazz-B to select the seemingly powerless Haschwalth as his right-hand man. The scene defied every expectation built up through their childhood training montage. What appeared to be favoritism toward weakness actually revealed the most calculated decision in Quincy's history.
Yhwach chose Haschwalth in the Bleach series because they shared the same rare Quincy ability—the power to distribute spiritual energy to others. This unique trait made Haschwalth invaluable to the Quincy King. Unlike typical Quincies who absorb reishi from their surroundings, Haschwalth possessed the ability to give power to those around him. This made him the perfect complement to Yhwach's own abilities, creating what the Emperor described as "a whole" when they worked together.
The story begins with two childhood friends hunting rabbits in the wilderness. Bazz-B showed off his Quincy skills with ease, while Haschwalth couldn’t even form a simple spirit bow at first. Their friendship formed when Bazz-B noticed bruises on Haschwalth's arm, signs of abuse from his uncle. The young prodigy took pity on his struggling companion and declared him his "minion."

For five years, they trained together with a shared goal. Both wanted to infiltrate Yhwach's forces and kill him from within. Bazz-B sought revenge for his family's destruction. Haschwalth simply followed his only friend's lead. During this time, Bazz-B's abilities flourished while Haschwalth remained seemingly powerless. The contrast between their skills grew more apparent with each passing day within the Bleach series.
When Yhwach arrived to recruit Sternritter members, everyone expected Bazz-B to be chosen. His talent was undeniable, his confidence absolute. Yhwach’s overwhelming presence crushed everyone—everyone except Haschwalth, who stood firm. The Quincy Emperor immediately recognized something special in the quiet boy who remained standing.
Yhwach revealed the truth that changed everything in Bleach. Haschwalth held a power equal to Yhwach, the Quincy King. He could share his spiritual energy with others, then reclaim it, enhanced after their deaths. This ability made him incredibly rare, perhaps one in a century. Bazz-B's growing strength over the years hadn't come from his own talent alone. Haschwalth had unknowingly been empowering his friend throughout their training.
The Power Behind Yhwach’s Choice in Bleach

The revelation in Bleach devastated Bazz-B's worldview. Everything he believed about his own abilities crumbled instantly. His "genius" was actually Haschwalth's gift flowing through him. Meanwhile, Haschwalth finally understood why he felt different from other Quincies. He couldn't absorb reishi because his power worked in reverse—he gave rather than took.
Yhwach needed someone who could complement his abilities perfectly. The Quincy Emperor had searched for over 200 years to find another with his unique power. Haschwalth represented the missing piece of his grand design. Together, they could achieve what neither could accomplish alone. This symbiotic relationship became the foundation of their partnership.
From Bazz-B's perspective, his best friend had betrayed their mission. They were supposed to infiltrate and destroy Yhwach together. Instead, Haschwalth accepted the role of right-hand man to their enemy. The bitter irony wasn't lost on either of them. The "powerless" friend had become the chosen one, while the "genius" was left behind.

Haschwalth's decision in Bleach stemmed from more than just recognition of his abilities. Yhwach had inadvertently freed him from his abusive uncle during the initial attack. The Quincy Emperor offered him acceptance, purpose, and power—everything he had never experienced. For someone who had always felt like a burden, this validation was transformative.
In the end, Yhwach’s decision to back Haschwalth completely shifted the direction of the Thousand-Year Blood War Arc. Their partnership in Bleach became the cornerstone of the Quincy invasion. The decision that seemed so surprising at first proved to be strategically brilliant. Haschwalth’s unique abilities made him the perfect partner to carry out Yhwach’s grand plans.
