Author's Note: I used one of the suggestions left in my comments. Can you guess which one it is? Good luck.

"Ye lord! Mask of blood and flesh, all creation, flutter of wings, ye who bears the name of man! Inferno and Pandemonium, the sea barrier surges, march on it to the south! HADO NUMBER 31, SHAKKAHO!"

Kiskue launched the projectile Kido from his hand, and just as quickly as it was released, it hit its target turning from a miniature glowing orb into a pillar of red fire.

"MR. AIZEN!" Pinkie Pie yelled.

She ran to help him, but was stopped as Gin grabbed hold of her.

"Stay here, Captain Aizen will be fine." He said.

She didn't believe him. She only struggled harder, but little did she know there was no way she could escape Gin's grasp.

"I promise. Captain Aizen won't lose."

This did little to give her comfort. Even if he won, she still didn't want anyone to get hurt. She couldn't do anything, so she let her mane fall into a flat shapeless figure.

The pillar faded away to reveal that Aizen was unharmed.

"What's the matter, you're not done already are you?" He said tauntingly.

Kiskue decided to try and stall Aizen. If he couldn't defeat him, he could utilize the time to come up with a plan.

"Why are we still fighting Aizen? This world has nothing you want. For now we should be trying to get back home!" He said.

"You think that your kido brought us here?" Aizen said. "This world is the key to everything."

Kiskue gasped.

"Can I ask you a question Kiskue?" Aizen said. "Why is it with your great intellect that you choose not to take independent action? Why do you choose to subjugate yourself to that… thing?"

Kiskue thought for a moment.

"When you say, 'that thing' are you talking about the Soul King?"

A moment of silence passed. Kiskue took that as a 'yes'.

"Without the Soul King, the soul society would split into pieces and the whole thing would fall apart. The Soul King is the keystone Aizen. That, my friend, is how the world works."

"NO!" Aizen yelled. "YOU'RE WRONG! THAT IS A REMARK ONLY A LOSER WOULD MAKE! A VICTOR SPEAKS OF HOW THE WORLD SHOULD BE, NOT HOW IT CURRENTLY OPERATES! AND I AM A VICTOR, I'LL DECIDE HOW THE WORLD WILL BE!"

Aizen tried to calm back down.

"Your kido didn't bring us here, I did." Aizen said calmly.

"THAT'S NOT POSSIBLE!" Kiskue said. "I know what happened! The hogyoku evolved my Kuyo Shibari!"

"No Kiskue, the hogyoku has already fused with me, it wouldn't evolve a kido."

Kiskue gritted his teeth.

"Surprised? Allow me to explain."

Aizen held up his zanpakuto.

"Have you noticed any difference in my sword ever since I shoved it through your chest back in Karakura Town? No, that's right, that wasn't even you. That was just your portable Gigai. Well, this is not Kyoka Suigetsu."

Kiskue gasped.

"It's a fake."

Gin let go of Pinkie Pie and stepped over to Aizen's side.

"Haven't you been wondering how Gin got here?"

Kiskue finally understood.

"He was here before all of us were." Kiskue said.

Gin took Kyoka Suigetsu out from behind his back and placed it in Aizen's hands.

"Very good."

He crushed the fake zanpakuto into dust, and gave a swipe of his hand across the real one.

"Thank you, Gin."

"And you know your objective?" Aizen asked.

"Yes." Gin replied.

"And you understand the importance of your task?"

"Yes."

"Good."

Aizen turned around to face the lake. It was serene and peaceful. The water was still and featured no ripples. He held out the arm containing his sword, and touched the tip to the surface of the water.

"Kyoka Suigetsu, Uma no Hansha ga arawareru."

The spell turned the surface of the water into a reflection of equestria.

"Jigen-kan, Uma no anrakku."

The water began to swirl into a whirlpool of sapphire water, until it turned into a portal to equestria.

"Should you forget it, the spell will be conveyed directly through this blade."

He handed his zanpakuto to Gin.

"Wait 48 hours until the moon is full in the sky, and make sure that the water is still."

"Anything else?" Gin asked.

Aizen paused.

"Good luck."

Aizen stepped to the side, beckoning for Gin to enter the portal.

He took a few steps forward, until he was knee deep in the water. He turned to face Aizen.

"So long Captain. See you soon."

He fell forward and leaped through the portal.

"You see, my zanpakuto has the ability to open portals to other dimensions on the surface of moonlit water." Aizen said.

"No, that part I get. But why here? Why do you need this world to kill the Soul King?" Kiskue asked.

"The only thing that can create a gateway to the dimension in which the Soul King is found, is the Oken. The King's Key. There is no document explaining it's location, but I discovered that the Oken can be forged with 100,000 souls and a plot of spirit enriched land with a radius of no less than half a spirit mile."

"And you plan to sacrifice this innocent world!?" Ichigo yelled.

"No, not this world. Just this town. My first plan was to use Karakura Town, but I'm saving it for… supplementary purposes. Besides, this world has nothing else that I want."

"Mr. Aizen?" Pinkie Pie stared at Aizen with watery eyes. "Is that… is that true?"

Author's Note: So there you have it. I used the suggestion posted by Xivern to explain how they got into equestria. I had a plan for it, but I liked Xivern's idea. So be sure to leave your own suggestions and they just might get written. See you next time.
