(Just my guesses here) So now I think we know why Quincy Zangetsu looks like Yhwach. After all, he is a part of Yhwach's soul. Interestingly, there must be something up with that part of Yhwach surviving inside Ichigo in spite of having to 'live' with hollow Zangetsu. Shouldn't they go ahead and fight each other to some glorified death?
