Hatred Ball

was Banryū's most powerful technique that was achieved due to a combination of the wrath of the 1,000 humans and 1,000 yōkai Bankotsu killed as well as having two 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.
