SPOILER
A giant test tube for a head, and one of the masks, at least part of it, looks familiar.
Well, at least the original headcover makes sense, now.
But damn, this particular Arrancar is big on redundancy: masks within a test-tube, underneath a flesh mask, underneath the original mask.

So it isn't really Kaien, but a hollow with the ability to make himself look like a dead loved one? Like how Grand Fisher got his 'fishes'
Either it is the hollow that Rukia thought that she killed when she killed Kaien...
Or it is just another hollow that has the ability to read minds and take shape of others...
Either way...looks like Rukia is in some trouble. They are probably going to use confusion techniques on her so this might be more of a test of the mind then the body. But hey, what do I know!?! -dg-
