SONIC THE HEDGEHOG Z

The corrupted king returns

Station Square Library, 12:02 PM

The janitor was cleaning up the library as people and mobions were searching for the books they were looking for. As the janitor cleans up a book shelf, a book fell from it.

"Oh my." The janitor said as he picked up the book and then gave a weird look at the cover.

The cover had written in golden medieval letters, 'Sonic and the Black Knight'.

"Odd, I wonder who might have written this book." The janitor said as he opened to read it.

But then something weird happened as he opened it: black smoke came out from it and it started spreading throughout the library. The janitor and everyone else were confused at this when…

"AH!!! A MONSTER!!!" a lady screamed as weird monsters emerged from the smoke.

These monsters where all wearing armours and swords and they started trashing everything in sight as people flee in panic.

"HELP! OPERATOR!!! CALL THE PRESIDENT HURRY!!!" a man shouted in panic at the phone when a fish-one shot an energy blast at the phone, reducing it to bits.

"AAAAAH!!!" the man screamed and ran away.

And then, a dark humanoid figure wearing, black and yellow armour with purple cape streams walked out from the smoke. It was King Arthur, the Black Knight.

"Finally, I am free!" King Arthur said. "That fool of a knight through he had finished me off, but my soul will live on in the depths of the underworld!" He turns to his demonic henchmen. "Spread out and search for Sir Sonic, slaughter him in sight!"

The knights of the underworld nod in agreement and they left the building as they started rampaging through the city, evolving it into chaos.

King Arthur then turned his attention to the janitor who was cowering under a table. The Black Knight grabbed his by the shirt.

"D-don't hurt! Please!" the janitor begged

"Silence!" Arthur roared "You go find the one called Sonic and tell him that King Arthur, the Black Knight has returned for revenge!"

The Black Knight dropped the frightened janitor down as he ran off out the door. Arthur then picks up the book and then he uses his magic to summon his horse, riding it out of through the window, crashing through it's glass and took of into the air.

Station Square Downtown, 12:03 PM

A 15-years-old Amy, a 9-years-old Cream and Cheese walk out of the Station Square mall carrying their groceries for lunch as they talk with each other.

Amy had grown a few inches during these years and she is now wearing a cobalt blue tank top and a matching skirt, both with sparkles and blue sneakers with white in front and back.

Cream had also grown a few inches and now she was wearing a dress with orange on her upper body and yellow on her skirt, and she still had the same sneakers she usually wears.

"Well, this should about do it for lunch!" Amy said

"Yeah, I can't wait to make that new dish that they mentioned at the restaurant!" Cream said. "It was so delicious!"

"Chao chao!" Cheese said

"You liked it too didn't you Cheese?" Cream asked

"Chao!" Cheese said

"Hopefully this time Sonic won't mess things up like he did last week!" Amy said with a threatening tone

"You are still mad about Sonic forgetting your date?" Cream asked

"Chao chao?" Cheese said

"Oh no, I'm over that, I just don't want him to forget the lunch, that's all." Amy said trying to hide her anger

"If I recall, Sonic said that he was summoned into the world of King Arthur and the Knights of the Round Table and had some adventures there." Cream said. "Is that true?"

"No way! That story is nothing but a lame excuse for forgetting our date!" Amy roared. "I mean, Sonic in the world of King Arthur?! What rubbish!"

"Okay…if you say so…" Cream hesitated

A sweat drop rolls down the side of their heads

"AAAAAH!!! MONSTERS!!! RUN FOR YOUR LIVES!!!" A bunch of people screamed in panic and almost ran over the two girls and the chao

"Whoa! What was that all about?" Amy asked

"Um, Amy?" Cream looked at something off screen that made her shake like a leaf

"What?" Amy turned and saw what Cream was looking at "ACK!!! What the heck are those things???"

King Arthur's knights from the underworld were coming toward them, rampaging through the streets, destroying everything in sight.

"What ever they are their coming right for us!" Cream was about to panic

"Chao, chao!" Cheese said.

Next, they were surrounded by the demonic creatures of the underworld. The two girls knew they had no choice but to fight, so Amy brought out her trusty Piko Piko Hammer, while Cream and Cheese made a fighting pose together.

First the soldier-ones leap toward them with their swords, but they dodge and Amy sends them flying by swinging her hammer on them, while Cream throws Cheese in his Spin Attack form at them. The defeated soldier-ones then disappeared in puffs of smoke.

Next the fish-ones flew toward them while shooting energy blasts at them. Cream flys toward them by flapping her ears like wings and throws Cheese again at them, knocking them all down. Defeated, they disappear in puffs of smoke too.

A giant-one stomps toward Amy with his lance and thrust it toward her, but Amy manage to dodge it, jump and slams her hammer on it's head, knocking it down, as it disappeared in a puff of smoke in defeat.

The battle went on for five minutes until Amy, Cream and Cheese appeared to be quiet tired, from all the fighting.

"Whew, that was tough." Amy said panting.

"Yeah." Cream said panting too.

"Chao." Cheese said also panting.

"But, just who were those monsters and where did they come from?" Cream asked.

"Whoever they were, we managed to teach them a lesson!" Amy said. "Come on, let's pick up the groceries and go to my place."

Meanwhile in the sky, King Arthur on his horse rode above the city but stoped when he looked down and saw the two girls and the chao, but what captured more his attention was Amy.

"Nimue…?" Arthur though. "So, the Lady of the Lake is here as well? I wonder if Merlina and the Knights of the Round Table are here as well? No matter, I shall take her as my prisoner and give me the scabbard, so I can rule again!"

Back on the surface, Amy, Cream and Cheese got up as they started picking up the groceries. Cheese then looked up and saw King Arthur head right for them.

"CHAO! CHAO! CHAO!" Cheese warned.

"Huh?" Amy and Cream looked and saw the Black Knight head right for them.

"AAAAAAAAAH!!!" a dark blur passed right over them

When the blur was gone, Cream and Cheese unshielded themselves and noticed that Amy was gone.

"Amy?" Cream looked around

"Chao?" Cheese looked around and saw something that disturbed him. "Chao chao chao!"

"Huh?" Cream looked up and almost screamed in panic. "AMY!"

"AAAH!! HELP!!! HELP ME!!!" Amy was caught in a net of energy beams coming from the Black Knight's dreaded sword, Deathcalibur.

"Hmm, strange…" King Arthur though. "The Lady of the Lake isn't this energetic. No matter, she is my prisoner now!"

King Arthur took off into the skys with Amy screaming for help, while Cream and Cheese watched helplessly.

"Oh no!" Cream whimpered. "Cheese! We have to warn Sonic and the others that Amy's been kidnapped!"

"Chao chao!" Cheese agreed.

Soon after Cream and Cheese left to find Sonic and the others, the knights from the underworld began spreading out from the city into the suburbs and beyond.

A/N: Uh oh, looks like the Black Knight has returned for revenge and kidnapted Amy, mistaking her for Nimue, the Lady of the Lake!
