King Mickey invited Sora, Donald, and Goofy to come to the castle. Sora, Donald, Goofy went to the castle. ``King Mickey, why did you call us here?'', Sora asked. ``I called you guys here to go on an important mission'', Mickey said. ``What's the matter?'', Sora asked. ``The Heartless are planning to invade a whole entire multiverse!'', Mickey said. ``WHAT?!'', Sora, Donald, and Goofy exclaimed. ``Yes, they plan to invade the world of the Cartoon Network multiverse'', Mickey explained. ``Cartoon Network Multiverse?'', Goofy asked. ``Why should we help people that's not even from our world?'', Donald asked, folding his arms. ``Because, we're heroes, Donald'', Sora said, ``and heroes help innocent people, no matter where they come from''. Donald sighed. ``How can we get to the Cartoon Network multiverse?'', Goofy asked. Mickey pulled out a blue wand from his pocket. ``Use this wand to enter the Cartoon Network multiverse'', Mickey explained, giving the wand to Sora.
Sora took the wand. ``Don't worry, Mickey'', Sora said, ``we won't fail you''. Sora opened a portal with the wand. Sora, Donald, and Goofy entered the portal. ``Be careful'', Mickey said.
Sora, Donald, and Goofy entered the Cartoon Network multiverse. Sora, Donald, and Goofy landed in the middle of city. Sora, Donald, and Goofy groaned as they got up from the ground. ``I guess this is the Cartoon Network multiverse'', Sora said, looking around. Sora, Donald, and Goofy saw looks of weird things. They saw three flying little girls (the Powerpuff Girls), three anthropomorphic bears (the Three Bare Bears from We Bare Bears), a boy with three strange looking ladies (Steven and the Crystal Gems), and many other zany characters. ``Weird place'', Sora said. All the characters were towards City Hall. Sora asked one of the characters, (Lumpy Space Princess), ``What's going on?'' ``Mayor Bunny is going to give a speech or whatever'', Lumpy Space Princess said. Sora, Donald, and Goofy followed the characters to City Hall.
Bugs Bunny appeared on stage and asked, ``What's up, everybody?'' Everyone began to cheer. ``Okay, I heard some news that there are some weird creatures have been attacking the city'', Bugs explained. ``Heartless'', Sora said under his breath. ``So, what do you guys think should happen next?'', Bugs asked. ``We should fight those creatures!'', Finn said. ``Yeah, LET'S KICK THEIR BUTT!'', Billy screamed. ``Does everyone have to fight?'', Panda asked. ``Yeah, some of us aren't really fighters'', Grizz added. ``Ice Bear will fight'', Ice Bear said. ``I agree with Grizz and Panda'', Lumpy Space Princess said, ``not everyone should fight. I'm not going fight! I can't afford to get my lumps messed up!'' Bugs Bunny rolled his eyes. ``Sora, let's get out of here'', Donald whispered. ``What?'', Sora asked. ``Yeah, these guys don't look like they need our help'', Goofy said. ``Are you guys listening to yourselves?'', Sora asked, getting frustrated.
Suddenly, the Heartless came. ``THE CREATURES ARE HERE!", Daffy screamed. ``OH MY, GLOB!'', Lumpy Space Princess screamed. Most cartoon Characters flee to their homes. The other cartoon characters began to fight. ``Take that, you fiends!'', said Samurai Jack, slicing a few of the Heartless in half. The Powerpuff Girls were also fighting the Heartless. Even, Ice Bear was fighting the Heartless. ``Be careful, little bro!'', Grizz said to Ice Bear, hiding behind a mailbox with Panda. ``Blop, blop, blop!'', Jake said as he smash the Heartless with his giant hands. ``Kids Next Door, ATTACK!'', Numbuh One shouted. The Kids Next Door began to fight. Cartoon Characters were either fighting the Heartless or hiding in a safe spot. Sora also began to fight. Donald face palmed himself. Bubbles looked down and saw Sora.
``Who's that guy?'', Bubbles asked. ``He's hair looks weird'', Buttercup said. ``Well, whoever he is, he's a good fighter'', Blossom said. Sora continued to fight the Heartless until there were no more of them. After eight minutes of fighting the Heartless, everything was back to normal. The cartoon characters came of the hiding spots and cheered. ``We're glad you're alright'', Panda said, hugging Ice Bear. ``Ice Bear is true warrior'', Ice Bear said. Grizz laughed. ``What were those creatures?'', Steven asked. ``They were Heartless'', Sora answered. Everyone looked at Sora.
``Who are you suppose to be?'', Finn asked. ``I've never seen you before in my life and I'm Uncle Grandpa, I KNOW EVERYONE!'', Uncle Grandpa said.
``I'm Sora and my friends and I came here to help you guys defeat the Heartless''.
``I think we kinda had it under control, kid'', Bugs Bunny said. ``Well, it was nice meeting all of you, but it's time for us to go'', Goofy said. Donald gave Sora an angry stare. Sora looked down with disappointment. ``Well, bye, guys we just met a few minutes ago'', Lumpy Space Princess said. Donald grabbed the wand, opened the portal, and went back home. Sora and Goofy followed Donald along. ``Did any of you know those guys?'', Bugs Bunny asked everyone.
Sora, Donald ,and Goofy arrived back at the castle. ``King Mickey, we're back!'', Goofy said. Sora was still feeling disappointed. Mickey came in the room and asked, ``Did you guys take care of the Heartless?'' ``Sora did!'', Donald shouted, pointing at Sora. ``Actually, most of the people in the Cartoon Network multiverse were beating up the Heartless. Sora helped them fight'', Goofy said. ``Mickey, why did you send us there to fight the Heartless if the people there actually didn't need our help?'', Sora asked. ``You dare question the king!'', Mickey shouted. ``What?'', Sora, Donald , and Goofy asked. They realized that something was wrong with Mickey. ``You heard me, you foolish boy!'', Mickey screamed, with his voice getting deeper. ``You're not Mickey!'', Donald screamed. ``Well, the truth must come out!'', Mickey said. Then, it turned out that it wasn't really Mickey!
It was...Xemnas! ``Xemnas!'', Sora gasped. ``Yes, you fools!'', Xemnas said. ``What did you do to King Mickey?!'', Donald asked. ``I'm keeping the mouse as hostage!'', Xemnas explained. ``Where is he?!'', Sora asked, taking out his keyblade. Xemnas began to laugh evilly. Sora yelled and tried to attack Xemnas with his keyblade. Xemnas dodged Sora's attack and kicked him the stomach. Sora fell down. ``Sora!'', both Donald and Goofy screamed. Then, Xemnas knocked Donald and Goofy out. ``Fools, the trip to the Cartoon Network multiverse was just a distraction. I have already taken over!'', Xemnas said. Xemnas grabbed Sora and opened the window. ``Look at it, Sora. Isn't it beautiful?'', Xemnas asked Sora. Sora looked up and gasped as he looked outside. Heartless were everywhere. Everything looked so dark and distasteful. ``What...have...you...done?'', Sora said, weakly. ``I won, you lose!'', Xemnas said. Xemnas locked Sora up in a dungeon. ``You can't get away with this'', Sora said, ``I'll stop you somehow''. ``I'll believe that when pigs begin to fly'', Xemnas said, walking off. Sora banged on the cell door and softly whimpered. Sora wiped his tears and said, ``This can't be the end.'' Sora began to bang on the cell door again. After banging on the cell door, Sora sighed and wondered, ``How am I going to solve this?''
