1: Ichigo's transformation into The Beast and Tousen's transformation into The Fly are not the same thing. Prior to his transformation Tousen invokes the name of his Zanpaktou and then some unknown Spanish phrase (anyone got a translation of that btw?) www.onemanga.com/Bleach/385/18/ and when the transformation is complete his sword is nowhere to be seen. (
www.onemanga.com/Bleach/386/02/) On the other hand Ichigo as The Beast wields Tensa Zangetsu to great effect (www.onemanga.com/Bleach/352/11/) This seems a pretty fundamental difference. Just no idea what it means yet.
2: Tousen's mask is... odd compared to every other Vizard we've ever seen. Ichigo, Shinji and the rest of the Vizard have simple face masks, maybe with a bit arching over to cover the crown of the head. Tousen's on the other hand covers his head pretty completely, leaving only his lower jaw and mouth free, something none of the Vizard masks do. Is this difference of design simply to allow Tousen to still visibly emote with his eyes covered or is something significant?
Just some thoughts to tide everyone over until we get more new Bleach.
