A/N: Unless you read the review I posted, yes I've made the final decision and I'm making an after math or 2 for the story. Also I've changed the title because that's the story I'm working on at the moment.
THERE AND BACK AT THE SPEED OF SOUND
Prologue:
It was the coronation day for the new princess Twilight Sparkle. The crowds outside Canterlot were cheering and overexcited for her speech. Afterwards we find Twilight with Spike at the library. "Oh Spike, I remember when we first came here." She told the young dragon. "Yeah, those were the days." Spike said. Just then Twilight got a headache and pictures of Sonic the Hedgehog appeared in her mind. "You okay Twilight?" Spike asked. "Yeah I'm fine; I just wish he was here." Twilight confessed. "Well how about we go on a picnic with our friends that should get your mind off things." Spike suggested.
"CONTROL!" Just then Shadow appeared strangling what looked like a Metal Sonic but black and orange. "Look Shadow, Tails repaired me so I could help out a bit." It said. "I don't care you still killed those in the past." Shadow confronted still strangling the look-a-like Metal Sonic. "Maybe, but I wasn't in full control of myself, it was Eggman who ordered me to committee those crimes." Shadow lightened his grip. "I was used and misjudged, just like you, and now I'm standing here with regret and shame." Metal finished and Shadow let go of it. "Fine but now we need to get home and without the Chaos Emeralds we need to use your Chaos Drive." Shadow explained.
Twilight and Spike interrupted. "Shadow?" They asked in unison. "What, then Tails' theory was right." Shadow said. "Wait who are you?" Twilight asked the robot. "Oh me right, I'm Metal Sonic Unit One, But you can call me Metal." Metal explained. "Look it's nice to see you again and all but the dimensions are still coming together and we need to get home." Shadow said and starts to walk out the door when he noticed something different. "Twilight you… wings… how?" Shadow asked pointing at the wings. "Oh it's a long story really." Twilight said. "Twilight became a princess and is now one of the rulers of Equestria and-" Spike was interrupted by Metal putting a hand over his mouth. "Yeah, yeah, yeah we get the story. *removes his hand and walks to Shadow* and about getting home, my Chaos Drive will need to recharge, so we're stuck here." Metal explained. Metal was black with orange streaks, an arm cannon replaced his right hand, black eyes with slightly yellow pupils and a red crystal kite shaped core.
Shadow just stood there with a really annoyed face. "Uh is it just me or is he annoyed?" Spike asked. "Nope he's pissed." Metal said shrugging at the question. Shadow then ran out the door and into the Everfree Forest. After that all they could hear was an explosion and Shadow entered afterwards. "Sorry, had to let off some steam." Shadow confessed. "Look just because I need to recharge-" Metal was interrupted by some beeping and his core started to blink. "Uh what's that mean?" Twilight asked. "Shadow you're not going to believe this, but there's a Chaos Emerald here." Metal explained. "WHAT!" Twi, Spike and Shadow all yelled in unison. "But, but then that means." Shadow said. "If that's true then we need to get to work." Metal said. "Right, we need to find that damn emerald." Shadow said and the four of them went searching.
"Shadow what's going on?" Twilight asked as she flew next to him with Spike on her back. Shadow and Twilight came to complete stop. "Look right now is not the time." Shadow explained leaving a face of confusion on Twilight. "Hey Shadow the emerald isn't far, just a few meters." Metal said as he stopped next to him. "Good." Just then they heard a scream not too far from them. "That sounded like Rarity." Twilight said and they all went to her.
Rarity was in front of the night mare Shadow feared most, Black Doom. "What?" Shadow asked. "I've been waiting Shadow." Black Doom was a devilish looking creature that had a sun and moon necklace, red robes, three eyes, floated above the ground, and had a very devilish voice. "Waiting for what AND HOW LONG?" Shadow confronted. "What's going on?" Rarity asked. "Just *starts breathing heavily* Stay *waves for her to move* Back." Shadow demanded and rarity moved behind them. "Only about five months, and to give you a warning from Mephiles." Doom explained. "What kind of warning?" There was a pause of silence before he answered. "Stone crumbles to dirt and dirt makes birth for new and threats." Doom explained and disappeared into dust. Shadow walked towards the dust. "AAAAHHHHH!" He slammed the dust with his fists and started to glow red. "Quick RUN!" Metal ordered and they ran. "CHAOS!" Shadow yelled as the group cleared. "BLAST!" an explosion cleared half the forest and shattered the sky. The green emerald dropped in front of Shadow as he knelt done with a face of clearness. "He's back." He said.
A/N: Yeah I know kind of short but don't worry it'll get better. Now this isn't going to be just a Sonic and MLP crossover. Yup that's right I got this planned and ready to go with a multi-crossover. If you have any questions or comments, just PM me or review I'll listen and answer.
