Banryū

Banryu, which can be translated to Barbaric Dragon, is Bankotsu's weapon as well as his "companion".

Description
Banryu is depicted as an incredible large halberd rivaling the strength and size of Inuyasha's Tessaiga. Its blade resembles that of a large double edged sword. Its pommel has a large, crescent moon like design. Due to its size Bankotsu is the only known human to wield it effortlessly as it took at least three men to haul it around. Even so, it has its limits as it was damaged by Inuyasha's Wind Scar. Bankotsu embeds two stolen Shikon Jewel shards in the blade to repair it, allowing it to fight on the level of the Tessaiga. Banryu is later on obliterated after being struck full-force by the Backlash Wave (In the manga Banryu stayed intact despite Bankotsu's death and, after having it's Shikon Jewel shards taken by Naraku, it was seemingly destroyed in the destruction of Mt.Haukrei). That attack also ends up killing Bankotsu.

In the anime, it was revealed that Bankotsu made a wish on the halberd; should he slay a thousand demons and a thousand humans and bask Banryu's blade in their blood, it would gain terrible demonic powers.

Attacks

 * Heat Blast(熱ブラスト Kanetsu Bakufuu)Bankotsu uses a series of flaming ball-like flashes that burn everything in sight.


 * Dragon Thunder(ドラゴンサンダー Ryuraisen) Bankotsu is able to summon a thunderstorm and manipulate the lightning creating a number of lethal electric bolts that almost kills everyone on Hijiri Island. The attack cannot be fully controlled, and hits randomly around Bankotsu. He only uses this attack in the anime, in Episode 113.


 * Dragon Hammer(ドラゴンハンマー Banryusen)Bankotsu can use an attack that is almost identical to InuYasha's Wind Scar except it's pink. He only uses this attack in the anime, in Episode 113.


 * Hatred Ball(憎しみボール Gojou Tama) Bankotsu's most powerful attack. The hatred built inside the halberd combined with the power of the 4 Shikon Jewel shards embedded in Banryu creates a huge and powerful ball of swirling anger and fire. However, this all-powerful attack is ultimately his downfall: InuYasha uses the Backlash Wave to shatter the Banryu and then the Hatred Ball since it was flowing with demonic energy. He only used the attack in the anime, in Episode 122.
 * Banryu Flash(禁止流フラッシュ Banryu Furasshu)
