"Huh !?" everypony gasped.
The tongue retracted to the ceiling.
"Yes it's mine at last!" shouted a voice of the one who could not be seen. The invisible creature started crawling away.
"Somepony stop him!" Rarity said dramatically.
The guards then fired their magic where the gem was, trying to stop the thief. but the strange foe was moving too swiftly to hit.
"Hey give that back!" Twilight said as she charged her magic and blasted the invisible foe.
"Yeeyoow !" the creature cried in pain.
The blast caused him to fall to the floor. Then the invisibility disappeared reveling a slightly dazed chameleon. He was a tall creature, he was around the size of Spike when he had that growth spurt (the first form) but wasn't quiet that big, his eyes were yellow with black pupils that were shaped like diamonds, he had a small yellow horn, his skin was green with some with other colors mixed in, his chest and belly were yellow, and there was a small curl in his tail.
He sprang up on to his hind legs and scanned around nervously.
"No you shall not have me!" the chameleon cried.
He then made several small dark blue spheres of energy appear and launched them at the guards, disabling them.
"Return the crystal !" Princess Celestea said.
She then blasted a giant magic beam at him. The creature retaliated by blasting a huge dark blue beam back at her's. The beams collided with great force, but the dark beam was too much for the princess and it easily blasted her back.
"NNAAAHHH!" she cried in pain as she was forced to the wall.
"Princess Celestea !" the main 6 and Spike cried as they rushed to her side.
"Don't worry about me, I'll be fine," she assured.
But as they comforted the princess, the lizard made his escape.
"Hey what about the thief ?!" Pinkie Pie pointed out.
By the time they realized that the chameleon still had the crystal, he had jumped out the window into the garden.
As the crook was falling he suddenly transformed into what appeared to be a motorcycle with one wheel and two eyes on its side. It then began to drive away.
The Ponies leaned out the window.
"What in Equestria?" said Rarity
"We have to stop him!" Fluttershy said.
"On it!" said Rainbow Dash as she darted toward the wheeled creature.
"Spike, look after the princess," said Twilight.
"Okay," he replied.
Meanwhile in the garden.
"You ain't getting away that easy," Rainbow Dash said before she slammed the creature.
The creature then spun out and transformed back to the chameleon.
"YEAOuch!" the Thief said.
The others had caught up.
"Wow A giant Gecko!" said Pinkie Pie.
"Gecko!?" the Thief shouted in annoyance.
"Actually, I think he's a chameleon," said Fluttershy.
"Thank you!" said the Chameleon.
"I don't suppose you want to give that crystal back?" asked Twilight.
"Oh look at the time, bye!" he said before he darted away.
"You ain't going no where!" Applejack then tossed her lasso and grabbed the thief.
"What oi, let me go!" the thief shouted.
The thief struggled to escape from the blond pony's grasp. He transformed into a sea serpent, a bird shaped jet, and a giant dinosaur. Then the thief turned into a light bulb then into a pile of cube shaped TNT!
"ssstttttiiiiiisss, Boom!"
"What the hay?!" Applejack said before she was blown away by the explosion. Then as the TNT was flying one of the blocks transformed into a big blue long armed mole which then tunneled into the ground.
"We can't let him get away!" said Twilight.
"Right!" replied everypony.
They then followed the trail of the tunneling creature.
Suddenly Rarity stopped and her horn was glowing.
"Hold on darlings," she said.
"What are you doing, he's getting away!" said Rainbow Dash.
"I can sense some gems here," Rarity replied.
"So ?" asked Applejack
"Sooo, if that chameleon is so obsessed with the crystal, he's likely to be interested in these gems," she said as she used her magic to pull out the gems.
The thief felt the gems and made underground U-turn to the gems.
the mole spun out of the ground towards the gems.
But before he could swipe them, Rarity and Twilight blasted him.
"WHOOAAAA!" he said as he was sent backwards.
"I can't believe it worked!" said Rainbow Dash.
"That's what you think!" the thief said before he transformed into a invisible robot.
"Stay back!" he said before he started blasting at the ponies.
"How do we stop him now?" said Fluttershy.
"Like this!" Pinkie Pie said as threw a pie at the lights of the cloaked drone. The Pie splattered all over the robot.
"Gaaahhhh, custard!" He shouted
Twilight blasted him and sent him flying.
"ERROR!" he said as he flew through the air.
The ponies ran to the impact site.
The thief had transformed back into the chameleon.
"Got you now!" said Rainbow Dash.
"Stop interfering!" the Thief then slammed the ground and made a transparent dark blue wall surround him, blocking off the ponies.
The thief then slashed his arms against the air and opened a portal. "He he he, the fate of all dimensions is about to change," the lizard snickered before he jumped though. The wall disappeared and the portal closed.
"NO, he's gone !" shouted Twilight.
The ponies had returned to the throne room.
"I'm sorry your highness, the thief got away," said Twilight .
"What was that thing anyway?" asked Rainbow Dash.
"I don't know," said Celestia. "Though it appears to not be from this world".
"Not from this world?" Said Twilight.
"As the legend says, there are many other worlds beyond Equestria," said the Princess as she used her magic to create a hologram showing many spheres with worlds in them. "This creature seems to have not just the power to shape shift, but the ability to travel from world to world," she said as the a hologram of the thief appeared.
"Whoa," said Fluttershy.
"Unbelievable," said Rarity.
"Makes sense to me," said Pinkie Pie
"That's nice and all but," started Applejack.
"How are we going to catch him?!" finished Rainbow Dash .
"The same way he escaped," said Celestia.
"Huh?" said everypony.
Celestia then used her magic and created a portal like the one the thief had made.
"You must catch the creature and not allow him to use the crystals power for evil",
"We won't let you down," said Twilight. "Spike can you stay here encase the Thief returns?"
"Of cores, just please com back safe," said Spike.
"Don't worry, we'll be fine," reassured Twilight.
"Besides we've fought much worse things before, we can handle a silly chameleon," said Rainbow Dash.
"Aw huh," said Applejack.
"Oki doki," said Pinkie Pie.
"Of course darling," said Rarity.
"mm hm," said Fluttershy.
"Alright then," said Twilight as she turend to the portal. " lets go girls!"
"Good luck my little ponies," said Celestia.
The ponies then jumped into the portal. They went through a colorful vortex, then everything went dark.
