Chapter One

The Heartless return

The sky was free of any clouds and the stars lit up the night. A cool breeze blew from the north and it felt good against Sora's cheek. Sora sat on the top of Merlin's house looking up at the stars. Sora smiled as he looked upwards and felt the breeze blow through his hair. The door behind him opened with a low groan. Sora looked over his shoulder to see Riku walking towards him and taking a seat next to him.

"What are you doing," Riku asked.

"Looking out at the night sky," Sora replied. Sora smiled to himself. He was happy that he and Riku could talk again.

"You're out here every night. Why?" Riku asked.

"I just like relaxing out here. No Heartless have materialized in any of the worlds recently and it would seem Maleficent and Pete disappeared after we beat Xemnas. It seems like there might be peace for quite a while."

"You realize that's wishful thinking right?"

"What do you mean?"

"You know the Heartless can come back at anytime and hoping it will be later rather than sooner is a wasted wish."

"You really know how to bring someone down, you know that?"

"I just speak the truth."

"Yeah, well the truth sucks, and it is not a wasted wish!"

Suddenly the door swung open with a large bang and Donald came running out onto the balcony.

"Sora! Come quick!" he yelled.

"Why?" Sora ask.

"Just hurry!" Donald yelled running back into the hotel. Sora quickly got up and ran after Donald with Riku following close behind.

Sora and Riku followed Donald down into what used to be Ansem's study. Cid, Yuffie, Leon, Cloud, and Kiari were all looking up at a large screen that just displayed a large fuzzy picture.

"What's going on?" Sora walked over to Cid and asked.

"I got this message I thought you should see," he said turning to the computer and started typing. Sora looked up at the screen just as a large file opened and the video started to play. The screen was a little fuzzy at first but it cleared up after a few seconds to reveal a boy with a really large head. He had dark brown hair that was done up in a swirl hair-do. He wore a red t-shirt with a yellow design of an atom on it.

"Greetings to any one who receives this message. My name is Jimmy Neutron," the boy said.

"Gawrsh, he has funny hair don't he?" Goofy asked looking at Donald.

"I'm to mesmerized by his large head," Donald responded.

"Shhh," Sora hissed as the boy named Jimmy started to talk again.

"Strange black creatures have invaded my hometown. The army can't handle them all. Requesting any extraterrestrial help from any life forms receiving this message. Please help save us!" the boy yelled. Suddenly a voice came from off screen.

"Jimmy they broke into the lab!" the high and annoying voice screamed. Jimmy turned and ran off screen just as a creature latched into the screen. Then the video stopped and the screen went black.

"That was a heartless," Sora hissed staring at the black screen.

. "So it would seem that the heartless have decided to attack some far off world," Merlin said stroking his long beard.

"They couldn't beat us here so they ran somewhere we couldn't get them," Sora said clenching his fists.

"Well they're in for the surprise of a lifetime. Because with the new Gummi ship Chip, Dale, and I just finished you can get to that world in no time," said Cid with a cocky grin.

"Really!" asked Donald and Goofy at the same time.

"Well I guess we're going on another quest,' said Riku.

"What do you mean we?" asked Sora.

"I'm coming with you. There's no way I'm letting you go alone with those two. Besides you're helpless without me."

"What!"

"And I'm coming too," said Kairi walked over to Sora.

"No way," Sora said seriously.

"Why not," Kairi said, "I can wield a Keyblade and Donald and Merlin have been teaching me lots of magic. Please Sora," Kairi said while using the puppy dog pout face.

"No Kairi I don't want you getting hurt." Sora said turning away form Kairi's pout before it started to take effect on him.

"Fine!" Kairi stomped out of the room.

"So when do we leave?" asked Donald.

"First thing tomorrow, so all of you go get some sleep," Cid replied. Sora, Riku, Donald, and Goofy left to their bedrooms to pack their things and get a good nights rest.
