Well I love bleach so I'm going to continue with the trivia (YAY!):
Trivia #18:
Each zanpaktou has a material form that it can take. When it takes this form, the true character of the zanpaktou is brought out. Kurosaki Ichigo's zanpaktou has the material form of an old man wearing a cloak quite like the ones used in the film matrix. This old man is called zangetsu (the name of the zanpaktou itself)
The only other person who's zanpaktou's material form has been shown is Abarai Renji from squad 13 (Juusan ban).
Renji's zanpaktou is called zabimaru (which transalates to "snake tail"). Zabimaru's material form is a baboon who's tail is.. you guessed it right.. a snake!
