Aizen gets killed by Don Kanonji

Aizen chuckled silently to himself from his position high above Karakura Town. Those fools…thinking they could take him on. How naïve, to think that their power could even almost compare to his supreme might. The difference was like that of Heaven and Hell, and if he wanted, Aizen could have easily just swept down and ended their miserable afterlives. But Aizen wouldn't do that just yet; he was having too much fun playing with his food. He took a look around. Only Kurosaki and the strongest of the Captains and Vizard remained standing. Everyone else lay about the carnage of the fake town, wounded and bleeding. Eventually, Retsu and Shunsui decided to release their Bankais. The shrill power, destructive force and spiritual pressure emitted between the two would be enough to wipe out the entire Spartan army five times over. But no, not Aizen. Aizen fought them for a while, soon causing them to retreat with his Shikai. That was when the old guy stepped forward. Aizen braced himself. Yamamoto may have been old, but that was precisely why he meant business. Especially if he went Bankai, which he only did on special occasions.

"Bankai!" said the old guy. Forget about the Spartan army, this guy could destroy the universe. Seriously.

Aizen's eyes narrowed. "Very well," he said, "I guess it's time for me to get serious too. Ban-"

However, the ex-Captain's long-awaited moment of crowning epic awesome was interrupted by a single cry of "Smells like bad spirits!"

And before Aizen knew what was going on, he was stabbed through the chest by a cheesy looking card-captor's style wand staff thing.

"Wh…at? Impossible!" was all Aizen managed, as his blood rained over Karakura town.

Kanonji wrenched the staff out, and Aizen's dead body swiftly plummeted to the earth below.

"Spirits are always with you!" chanted Kanonji, as he was ogled up upon by several Shinigami, "Bwahahahahaha!"

He then disappeared, to wherever it is he lives.

The Shinigami simply sat dumbfounded, starring at the spot Aizen and the strange human recently were. Yamamoto was left hanging in his Bankai.

"Sooo…" mused Shunsui, "Now what?"

End.
