The Tornado touched down at the forest's edge followed by the girls' hot air balloon, allowing everyone to get off. Sonic stood next to the girls who looked rather nervous.
"C'mon girls! It's just a forest! Why so shaky?" Sonic asked.
"W-well...I don't know about you but for some reason, something just doesn't feel right." Applejack said.
Rainbow Dash frowned. "Oh C'mon girls! The last Element of Harmony is in that forest! Are we gonna give up just like that? No we're not!" she declared.
Twilight nodded. "She's right. Scared or not, we don't really have another choice! If we don't find that element, Eggman's plans for domination will succeed and Equestria is doomed! So let's stop shaking and start running! We have little time left!" she announced.
The 6 ponies and Spike nodded.
Sonic grinned before dashing off into the forest with the rest of the group right behind him.
(Stage: Everfree Forest)
Sonic raced through the trees and grinded the rather large vines as he searched for the final portal leading to the final element.
Twilight and the others were close behind, fighting their way through the thick brush and groups of badniks. Twilight and Rarity used their magic to blast them into oblivion, Applejack resorted to her sheer strength while Pinkie let loose her party cannon, somehow turning the robots into cake batter, while Fluttershy and Rainbow Dash relied on their mid-air maneuvering.
Sonic and Rainbow were the first to arrive at the site of Dr. Eggman's base and the epicenter of the element's signal.
"I had a feeling Egghead would be quick to set up shop! Now all we have to do is find that portal, get that element, trash this base, and we're good to go!" Sonic said.
Tails and the others soon caught up. "SONIC! WAIT!"
Sonic turned back to see Tails with his handheld. "Huh? What's up buddy?" he asked.
The two-tailed fox held up the monitor which showed 3 signals. "I don't think we're the only ones here! I've just picked up 2 signals but they don't appear to be signals like the elements. They look like signals given off by Chaos Emeralds!"
Sonic's eyes grew wide. "Chaos Emeralds?! How'd they end up in Equestria?! Wait...that was a pretty stupid question. Let me rephrase that. How'd Eggman get ahold of the Chaos Emeralds?!" he asked.
Suddenly the group was face to face with a certain blue Sonic lookalike. SONIC THE HEDGEHOG. LONG TIME NO SEE!
Sonic grimaced. "Metal Sonic! I thought I pulverized you the last time we met!"
"What the fudge?! It's a robot that looks like Sonic!" Pinkie exclaimed.
Twilight frowned. "Don't worry Sonic! We've got you covered!" she said, readying her combat spells.
Sonic looked back to the girls in hesitation. "As much as I appreciate the help, Metal Sonic is MY problem! Don't try to help me! I have to stop this imposter myself!" he declared, looking back to the robot.
IT WON'T BE SO EASY THIS TIME. I HAVE MY OWN PARTNER! Metal buzzed.
Next to Metal Sonic ascended a robotic lookalike of Rainbow Dash!
The real deal went slackjaw. "What the?! It's me! As a robot!" she exclaimed.
Metal Sonic laughed in monotone before turning away. CATCH US IF YOU CAN! he then flew off with the robotic Dashie following.
Sonic and Rainbow Dash gave chase.
(Boss: Metal Sonic)
Sonic landed on a long bridge that seemed to wind all the way around the base. Metal Sonic zoomed overhead as the blue hedgehog took off after him.
"Alright Metal! This time I'll make sure ol' Humpty Dumpty can't put you back together again!" he taunted.
Metal shrouded himself with electricity before diving towards his target only to miss at the last second then being homing attacked by Sonic! The robot easily recovered with minor dents and scratches before flying to the side and beginning to ram into half finished support beams, ripping them from their attachments and sending them right at Sonic only to have them boosted right back at him!
Sonic grinned. "C'mon tin can! You were actually tough when we first fought!"
Metal Sonic had now switched gears to kill mode. He summoned electrical balls from his metallic hands before rapidly firing at Sonic.
The blue blur quickly dodged all the shots before landing another homing attack on Metal Sonic.
The blue robot plowed into the metal bridge, causing it to collapse from behind Sonic. Metal then slammed into the bridge from the bottom, resulting in major segments to give way. Sonic jumped from one falling platform to the next before successfully landing onto the still stable parts of the bridge. Metal Sonic ripped a hole to get back in the air above the bridge before pausing to recover his energy. Sonic was still struggling to keep himself from falling behind and actually falling. As Metal Sonic was about to fully recover, Sonic quickly jumped in the air and landed yet another homing attack.
Metal Sonic was beginning to smoke and sparks were shooting out from his body. He was beginning to short circuit but still had the energy to carry through his last objective: Destroy Sonic. He zoomed off far behind Sonic before overloading and frying his circuits to shroud his metallic chassis in electricity then charged at Sonic full speed.
Sonic boosted to try to outrun the attack but Metal Sonic was gaining on him. But just as Metal Sonic was about to make contact, he shorted out and weakly attempted to keep his power levels stable. Sonic saw the opportunity and landed one last homing attack. Metal Sonic was sent flying into the air.
Sonic quickly landed before rocketing back up to Metal Sonic and finishing him off with a swift roundhouse kick. Metal Sonic careened backwards before finally exploding.
Sonic landed before rushing back to the group.
(Boss: Metal Rainbow Dash)
Rainbow Dash soared high into the sky in pursuit of her robotic impostor. Metal Rainbow turned back and hovered in front of the real Dashie with its cold lifeless LED eyes meeting Rainbow's real nervous eyes.
DR. EGGMAN'S ORDERS. EXTERMINATE RAINBOW DASH AND HER ALLIES It buzzed.
Rainbow Dash frowned. "Dr. Eggman? You're just another one of his machines then! Well prepare to find out what I do to his machines, Faker!" she exclaimed.
Metal Dashie flew ahead of the real pegasus before sending the hyper engine on its back into overdrive. The exhaust exploded, expelling a burning hot blast of fire. Rainbow Dash gasped and quickly flew out of the way before ramming into the robot's underside. It began to lose altitude but quickly recovered and flew back up. Metal Dashie activated her weather manipulation mode and grabbed a massive cloud before giving it a hard buck, causing it to let loose a wicked charge of electricity. Rainbow Dash was hit and began to fall but quickly shook herself back and regained control before striking Metal Rainbow Dash again.
"You think a little weather's gonna hurt me?!" she taunted.
The metallic look alike kicked into crush, kill, destroy, and swag mode and began to pick up speed before performing a Sonic Rainboom, making a sharp turn, aiming at Rainbow Dash. The rainbow-maned pegasus had no time to react and was rammed into, sent flying off.
Metal Rainbow Dash laughed. I AM THE REAL RAINBOW DASH! I AM THE IRON PONY! it was about to fly off in search of MEtal Sonic before its radar picked up something coming in fast. Turning its head to the source, Rainbow Dash could be seen coming in fast, doing a Sonic Rainboom as well. Metal Dashie was struck hard but somehow managed to remain intact although now was beginning to smoke and spark.
Rainbow Dash grinned. "Not so tough now are we?"
Metal Dashie had one last directive: Destroy. The robot overloaded and fried its circuits before enshrouding itself with electricity and flying full force, locked onto Rainbow Dash. The pegasus attempted a Sonic Rainboom, hoping to outfly her copy but it was right on her tail. Just as the electricity would surge through Rainbow's body, Metal shorted out and began struggling to maintain power levels, giving Rainbow Dash an opening to slam into Metal one last time. The robot was sent flying. Rainbow Dash zoomed over for the finishing blow and roundhouse kicked it. Metal Rainbow Dash was sent careening backwards before being engulfed in a fiery explosion.
Rainbow Dash grinned. "There's only one Rainbow Dash!" she said before flying back down to the ground and her friends below.
