Hatred Ball

was Banryū's most powerful technique that was achieved due to a combination of combination of Bankotsu killing 1,000 humans and 1,000 yōkai, as well as having Shikon Jewel shards embedded in it. It created a swirling fiery ball of yōki.

Bankotsu used this attack during his final confrontation with Inuyasha in the caves of Mount Hakurei. This powerful attack however, lead to Bankotsu's downfall as it allowed Inuyasha to use the Bakuryūha against him.
