This is my first Fan Fiction so please go easy on me. Any suggestions or criticisms are appreciated.
To note on this story, it takes place after the events of Kung Fu Panda 2 but before Legends of Awesomeness, after the events of season 1 of Jackie Chan Adventures, directly after the events of Karate Island for Spongebob, and after the finale The Hong Kong Longs for American Dragon: Jake Long. I will also note that this story has two alternate universes, the first being the animal world and the other the human world. Without further delay, enjoy the story.
The large dragon demon hovered above the rocky cliffs of the castle rubble. He scowled looking down at the celebration that Jackie Chan and the rest of Section 13 seemed to be having.
"Those fools!" he thought to himself. "They assume that a few measly talisman can kill me so easily. My power extends greater than they could ever imagine! They'll see, they'll all see!"
"Meditate, concentrate…" she thought to herself. She began to chant. The chanting became louder and louder until…
She burst out of her cage, smashing the wood to pieces. She glared at Master Udon.
"I won't give into your time share vacation scam!" Sandy yelled.
"Then give into my fists!" Master Udon screamed.
Sandy lunged at him and slapped him with her feet in midair. He grabbed her and smashed her into a wall, debris crumbling down on Sandy.
She leapt back up and slammed her hand as hard as she could toward Udon. It was blocked by Udon and they threw punch and chop over and over again, each time blocking it. Sandy grabbed Master Udon's hand and tossed him into the air. She jumped up and aimed her foot at his face. With a satisfying crunch it connected with his face, knocking out some of his teeth. He flew back through the wall and fell down the tower into the ocean.
"You're in soup now, Udon!" she yelled down from the hole in the wall.
She walked over to Spongebob and cut the ropes from around his arm.
"You okay little square dude?" she asked helping him up.
"Yeah, I'm fine." He looked down in shame.
They walked down the stairs in silence to the boat at the beach waiting for them. Sandy and Spongebob got in and began to paddle away from the island.
"Sandy, I'm sorry I acted like a jerk back there. Thanks for saving me from…buying a condo."
"Aw shucks, Spongebob, that's what friends are for."
The demon slowly floated toward the large black and purple portal in the temple. He looked into it and saw what looked like China, but with animals in place of the people. It looked as though the city was cleaning up after something akin to a war.
"Perfect. Gongmen City. It is here that I can show that Jackie Chan my true power. All hell will reign down on those who defy me!"
