Yamamoto's "zanpakutō" is , and it displays control over flame. It is the most powerful "zanpakutō" in Soul Society, and the sheer power of the flame can disintegrate almost anything the sword is waved at. Its release command is "Reduce All Creation to Ash" (万象一切灰燼と為せ, "Banshō issai kaijin to nase" or "All things in the universe, Turn to ashes" in the English Dub). "Ryūjin Jakka's" Bankai is which upon release causes all of the flames produced by Yamamoto to be concentrated at the edge of the blade, which takes on the appearance of an ancient, scorched sword. "Zanka no Tachi's" heat reaches temperatures of 15,000,000 degrees, creating flame-like reiatsu around Yamamoto, which renders him untouchable. Merely activating it drains all the moisture in Soul Society. Even squad ten current captain, Toshiro Hitsugaya, cannot release his sword due to the heat radiated from Yamamoto's bankai. Its power is so great it can destroy the entire Soul Society and Yamamoto himself should it remain active for too long.
