Zanpaktou Name: Zangetsu (斬月, Moon Cutter or Cutting Moon):
Zanpaktou Spirit: "Old-man Zangetsu" (斬月のオッサン, Zangetsu no ossan):30 to 40-year-old man with unkempt facial hair and long ragged black hair. He dresses in tattered all black garbs with narrow sunglasses and a long flowing overcoat that flares out into ragged ends.
Inner World: In a all blue horizontal city on a skyscraper
Type/Element: Dark
Physical Appearance: an oversized elegant cleaver rather than a formal "katana". He has no crossguard and no proper hilt; what Ichigo holds is the cloth-wrapped tang. The sword is as tall as Ichigo is, 1.75 meters, and has a black blade with a silver edge. The cloth wrapping on the tang seems to react to Ichigo's will, changing length at a thought or twining about the blade in an impromptu sheath. When in combat, the cloth falls away when necessary, shrinking back to a manageable size.
Special Features: Unlike most Zanpakutō, which can be sealed into their original form, Zangetsu is always in its Shikai form. Yoruichi Shihōin has stated that his Zanpakutō is a full-time released form type because of Ichigo's vast but uncontrollable spiritual energy upon generation of it, implying that it is simply a type of Zanpakutō that without proper control of his spiritual energy, once in Shikai form, it remains in its said state.

Bankai Release Phrase: BAN-KAIII!!!
Bankai Appearance: Tensa Zangetsu (天鎖斬月, Heavenly Chain Moon Cutter or Heavenly Chain Cutting Moon): It is considered completely out of the ordinary for any Zanpakutō. Unlike most Bankai forms, which usually create some sort of massive creature or effect, Ichigo's Bankai actually shrinks his sword down to a daitō (Japanese long sword) with a black blade. The crossguard has four prongs bent out to form the shape of the manji (which is the kanji for "ban," meaning "full", as in "full release"). In addition to his sword, Ichigo's robe is replaced with a long-sleeved, ankle-length black coat with red lining that is closed at his chest, then left to flare out into ragged ends, much like that of Zangetsu himself. This coat is part of Ichigo's Bankai and the damage it can take is directly proportionate to the remaining strength and level of Ichigo's Reiatsu
