Even though it's the main characters bankai, Zangetsu's is my favorite. I love everything about it. I like the fact that Ichigo obtains Zangetsu's coat. I like the concept of his zanpakuto swallowing his reiatsu, condensing it and releasing it from the tip of the blade and the immense speed. Ichigo's bankai is well known and unique. When he is being persued by a villian they are given the information, "orange hair, and a black bankai", and they know it's him when they see him.
He hasn't used his speed like he used to but man, his speed was dope in his first time using bankai. So thats why it's my favorite.
