Rainbow Dash and Sonic's Adventure

Taimuwāpu appeared before them.

"A super pony!? Impossible!" he cried.

"Heh! Now, get ready to see our true power!" Sonic smirked.

He stood up on Super Rainbow Dash's back, and then turned super himself.

"No matter, not even the "ultimate life form" could stop me!" Taimuwāpu chuckled evilly.

Super Sonic flew at the echidna at full speed and kicked him on the cheek. Taimuwāpu was sent flying through an iceberg and then on the freezing ground.

"Too easy!" Super Sonic taunted.

The hedgehog flew over to where Taimuwāpu had landed.

"Super Sonic Wind!" Super Sonic yelled as he launched a sphere of energy at the echidna.

A big explosion happened and Super Rainbow Dash came out of it, punching Taimuwāpu. The other ponies watched nervously as the deadly brawl went on. Super Sonic turned into a spin ball and rammed Taimuwāpu out of Super Rainbow Dash's aim, sending the echidna flying. Suddenly, he came soaring back.

"Huh?" Super Sonic gasped, barely avoiding the body.

Shadow appeared in front of them.

"Prepare to meet your fate!" he shouted as he transformed back into super form.

"Hey, what if we use light-speed attack?" Super Sonic suggested.

"Heh... you never cease to surprise me." Super Shadow chuckled.

"What's "light-speed attack?"" Super Rainbow Dash puzzled.

"Just follow my lead!" Super Sonic replied.

He and Super Shadow both spun into a spin ball and started to collect energy. Taimuwāpu teleported back to find the two super hedgehogs.

"Ah yes, light-speed attack, if I recall. That cannot stop me." he challenged.

Super Sonic and Super Shadow busted out of their spin ball at the speed of light and started kicking Taimuwāpu back and fourth.

"How can I help?" Super Rainbow Dash asked.

"Just throw him around!" Super Sonic yelled as he slammed his fist into the echidna's head.

Super Rainbow Dash waited for Taimuwāpu's body to fly downwards before bucking into him.

"Agh!" he cried as he flew through the sky.

"Element Wind!" she shouted.

The Element of Loyalty lit up in a flash and shot a laser that hit the echidna's body. After the beam cleared, there was no sign of Taimuwāpu. They waited a few minutes, nothing happened. Super Sonic's face lit up with a smirk.

"That was tight!" he exclaimed.

"Perfect as always!" Shadow replied, and then fist-bumped with the hedgehog.

He and Super Sonic teleported to the ground, they turned to normal form. Sonic scooped up the Chaos Emeralds.

"Sonic!" Super Rainbow Dash cried.

Sonic turned around to see her fly down too him. Super Rainbow Dash's friends cheered at their victory.

"Dashy..." he began, his eyes filling up with tears.

Super Rainbow Dash powered down. The only thing separating them now was the harsh blizzard, but they didn't care. Sonic slowly approached the pony. Suddenly, their moment was ruined by an angry Taimuwāpu smashing into the ground, cracking it.

"You fools!" he laughed evilly.

The echidna's hand lit up in a dark aura. The energy drained from the elements, and then from the emeralds. Both sets turned dull in color from lack of power.

"What!?" Sonic gasped.

"Oh no you don't!" Twilight yelled bravely.

Her horn lit up in a magical light and an icy bolder rolled from a mountain, straight at Taimuwāpu. The echidna formed a ball of flashing colors toward the giant rock and shot it. The bolder exploded into bits.

"You think that was impressive!? Watch this!" Taimuwāpu taunted.

He flew up to the top of the mountain, the whole top lit up. Out of nowhere, the ground started to rumble.

"Sonic!" Shadow called urgently.

Sonic looked up fast enough to see the rocks and snow come tumbling down.

"It's an avalanche!" Rarity cried.

"And at this rate, it'll crush the Crystal Ponies!" Sonic informed.

"Quick! You guys get to safety! I'll... figure something out!" Shadow commanded.

Sonic and the others moved out, but, Rainbow Dash stayed put.

"Dashy! Come on!" Sonic screeched.

"No! I don't care what happens to me! I've got to protect the Crystal Ponies!" Rainbow Dash replied loudly.

Sonic couldn't just sit and watch Rainbow Dash get killed. The avalanche came crashing down, and he went his fastest to protect her.

"I'm sorry... I love you!" Sonic confessed as he sky-uppercutted the pony, causing her to fly into the air.

The rocks smacked into the hedgehogs and Sonic's attack allowed it to miss Rainbow Dash by a little. She was bewildered at seeing him buried under the snow. Her magenta eyes filled up with tears. Taimuwāpu reappeared over the scene.

"Is that proof enough for ya?" he smirked.

But, something stopped his snooty attitude. Rainbow Dash's tears made something come over him.

"Sorrow?" he whispered.

Suddenly, his fur flashed peach and his iris turned purple for a split second. His fur flashed back to the reverse, and then back again. Rainbow Dash watched in amazement as he held his peach fur and purple iris form for a few seconds, holding his stomach as if out of breath.

"Help me! P-please! It's-" Taimuwāpu cried before flashing back to his evil form. "Your puny emotions don't affect me! And that of the Crystal Ponies don't either!"

"Y-you killed them... you deserve to die..." Rainbow Dash couldn't sound brave because of her crackly voice.

"No, they got in the way. The avalanche was just a decoy. I would've rather preferred that they would've died slowly and harshly." Taimuwāpu snickered.

"What do you mean "a decoy?"" Rainbow Dash asked, still full of sorrow.

"Sombra!" Taimuwāpu called.

A ferocious roar could be heard from the ruins of the Crystal Empire. A dark pony busted through the debris and to the echidna's side.

"At last, I finally get to meet you." the pony's deep, evil voice said.

"Impossible! We banished King Sombra!" Twilight cried.

"Ah, but I'm not King Sombra, I'm his father!" the pony replied with a vile smirk.

Sombra did indeed resemble King Sombra, except he wore heavy, dark armor that hung on perfectly to his body. His eyes were glowing green with a purple wave coming out of the side.

"We'll just defeat you with the elements!" Twilight yelled back bravely.

"How do you suppose you do that with no power?" Taimuwāpu growled.

Twilight looked at Rainbow Dash's body. It was true that the elements were dull in color and had lost their power. Taimuwāpu omitted a small laugh from his lips.

"Now, prepare to meet your fate!" he exclaimed. "Ready, Sombra?"

"Ready..." Sombra chuckled.

"Chaos Control!" they said in unison.

The two disappeared and a bright light appeared between where they used to be. When it faded, sparks of dark energy came from the echidna that was standing there. The echidna's body was black, it had grey armor on. Its eyes were glowing green, with purple coming out of the side.

"Are you Sombra, or Taimuwāpu!?" Applejack demanded.

"Both, we are Sompu!" the strange echidna replied.

"They fused!" Rainbow Dash gasped.

Before the mutation spoke, the Chaos Emeralds started to shake a bit.

"All of you ponies are so pathetic! You actually believed that you could stop... me!? Us!?" Sompu taunted, not noticing that the emeralds were growing.

"Those emeralds...!" Rarity muttered.

"Do not speak while I'm speaking, tiny fool! I'm your new ruler, I rule all!" Sompu snapped.

The overconfident echidna cried out in pain as his energy was drained and provided to the now double-sized emeralds. They were Super Emeralds!

"Fusion!? Well, two can play at that game!" a familiar, cocky voice shouted.

A peach arm with a glove-covered hand busted through the rock and sleet. It supported the owner and out came Sonic, and then Shadow. The Super Emeralds spun around the two hedgehogs.

"No! Impossible! It's-!" Sompu cried, before being interrupted by a burst of white light.

"Ngh! What's with that bright light!?" Rainbow Dash shouted.

"Chaos Control!" two voices yelled.

With some more amazing lights, the transformation was completed. There, standing in the place of Sonic and Shadow, was a white hedgehog. It resembled Sonic except it had a white patch of fur on its chest, it had red stripes on some of its spikes, and its shoes were a mix between Sonic and Shadow's.

"Sonic?" Rainbow Dash croaked.

"Shadic!" the hedgehog replied.

Sonic and Shadow had transformed into Hyper Shadic!
