Kurotsuchi fights zombie Quincy and Shinigami with Frankensteined Arrancars. I giggled. This might be the most perfect fight in the history of the franchise.

Also, I figure the selection of Frankencars means that Mayuri probably collected every Arrancar corpse he could from the Aizen War. Considering that it turned out he was building an army, I don't really blame him. Maybe if Giselle busts out her own Vollstandig, we'll see Kurotsuchi summon FrankenStarrk, FrankenYammy, FrankenNnoitra, and such like.
