User blog comment:Zwann/Vasto Lordes in the Espada, let's analyze./@comment-1511643-20091017114255

-I still don't think anyone in the Espada was a Vasto Lorde, mainly because (except for Starrk and Halibel) I wouldn't classify them as humanoids-

- if not for the fact that Yammy, who is the cero espada (which, presumably, makes him the strongest) doesn't look even a bit Humanoid.-

I think you're getting the definition of humanoid off. It doesn't mean exactly like human. It means two arms, two legs, the basic shape. Grimmjow's release is perfectly humanoid, it's just not human. Szayet's is not. Ulquiorra's is humanoid + wings, not perfectly humanoid but close. Yammy's is humanoid without a doubt, it's simply a huge humanoid.
