In shounen manga, all ultimate attacks must be eventually topped by even more powerful ultimate attacks, and Bleach has proved to be no exception. Releasing his “final form” (Letzt Stil) has put Kirge into a grandiose mood, and he begins bragging incessantly about how frightening and unnerving his powers are. However in manga, final forms tend to be powerful only when they are one time use (as in the case of Ichigo or Ishida). Supposedly the greater the sacrifice, the greater the strength, and this raises some doubt to Kirge’s claim of his Letzt Stil’s overwhelming power. Though in some ways it seems like any other bankai or resurreccion, it does share the Quincy characteristic of reishi absorption, allowing him to draw power from the environment of Hueco Mundo itself, including the ground, trees, and even Inoue’s Santen Kesshun. This seems to grant him an insanely high defense, though it’s not actually clear whether he dodged Ichigo’s Getsuga Tenshou or just blocked it.
Ichigo can probably see that this guy will be much tougher than Ivan, but I do have to agree with his assessment of the aesthetics of the angel-clown Nazi’s costume. Before Kirgie can release his “divine power” though, Ayon shows up again, courtesy of Harribel’s three Fraccion. From the few panels in which they are shown, it’s difficult to tell whether they had to sacrifice more body parts to summon him, but they certainly are a tenacious bunch. The last time Ayon made an appearance he went on a Hulk-like rampage, displaying ridiculous brute strength until Yamamoto cut him to BBQ strips, so I’m very curious as to how this fight with Kirgie will turn out.
