Badass sword owned by the one and only Kurosaki Ichigo from Bleach. In its shikai form the sword looks kind of like a giant butcher knife. In its bankai form it's a long, black katana. And its persona is that of a scruffy-looking man in black who is TOO BADASS TO ACCURATELY PUT INTO WORDS.
Zangetsu is the zanpakutou of Ichigo Kurosaki. In its shikai(initial release)form it looks like a giant cleaver. Its bankai (final release)form is a black katana or nodachi with a handguard in the shape of the manji.The materialized form of Zangetsu appears to be a middle-aged men with middle length black hair wearing black cape.
