(Final Boss: Egg Shrine)
(Phase 1)
Sonic chased after Eggman's mech at a speed FAR from the speed of sound. A bright yellow tail trailed behind him as he accelerated onward.
Sonic was about to go in to attack before he heard a familiar voice in his head.
[Sonic? Can you hear me? I'm using my magic to both contact you and keep track of your energy and movements. From what I can tell, your energy levels are sky high. Tails has told me about the Chaos Emeralds and how only you can fully tap into their power. (*insert time limit and rings quote here*) Be very careful! The Elements of Harmony are very powerful on their own let alone modified with a foreign energy. The fate of Equestria lies in your hands now.]
Sonic nodded in understanding. "Roger that!" he said before going in to attack.
Eggman grinned. "That's it hedgehog! Come closer!" he said before slamming down his fist on a button.
The girls were sapped of energy as the Egg Shrine conjured up multiple drill like homing shots!
Sonic evaded them with ease before getting close enough to one of the capsules and attempting to boost into it only to have dozens of volts of electricity surge through his body! "Agh!" he grunted in pain before recovering.
Eggman smirked. "I had a feeling you'd try something like that!" he said before flipping one of 6 switches. "Think you can dodge THIS?!"
The capsule Sonic attempted to break began draining energy from the pony inside or in this case, Rarity. Once enough energy had been taken, Twilight's capsule synced energy with Rarity's to summon Sonic's harmonic ability: Spikes! Dozens of purple, magical, pointed spikes appeared before rocketing right at the golden hedgehog.
Sonic tried to maneuver out of the way but the spikes were too fast! They hit directly causing the supercharged hero to briefly lose control. "AH!" he exclaimed.
Eggman grinned. "How do you like that!?" he yelled.
Cubot checked the mech's status. "All power levels are stable but Rarity's power has dropped. It will take some time for it to recharge." he explained.
Eggman smiled. "No worry! We have all the time in the world! Sonic on the other hand is losing his pace!"
Sonic growled. "Oh man! This is gonna be tough!" he slowly approached but stopped as he heard Princess Celestia again.
[Sonic, With Tails' help, I've managed to intercept the signals and readings coming from Eggman's robot. After he's used one of the element's abilities, it has to recharge. That's your chance to strike the capsule! But be quick! An electrical barrier is protecting it and only goes down for a moment after an attack. Keep an eye out for that opening!]
Sonic glanced towards Rarity's capsule and noticed that the barrier was down. "Now's my chance!" he charged full speed before unleashing a chained homing attack on the capsule!
After the 3rd strike, the capsule broke off of its supports before falling to the floor below. It shattered on impact but Rarity remained unscathed!
Eggman glared. "You little! I'll make you pay for that!" he yelled before flipping another switch. Just like before, Rainbow Dash's capsule charged and synced energy with Twilight's magic to summon a powerful rainbow colored beam of energy.
Sonic was ready this time and quickly dodged out of the way, barely missing the attack before rushing over to do the same as with Rarity. On the 3rd strike, Rainbow's capsule broke free and plummeted to the ground below.
"Boss, now that the two capsules are gone, our power levels are at 80%." he announced.
Eggman glared. "I know that! Just let me fry this stupid hedgehog!"
After a repeated process, only Twilight's capsule remained.
[Watch out. I'm getting strong readings from the last capsule! Eggman's using it as a charging station for the mech! He's planning something!]
Sonic kept his distance as the capsule finished charging.
"Lights out Sonic!" Eggman screamed before slamming down a button.
Twilight's magic summoned a monstrous blast of magical energy and let it loose at Sonic!
[Sonic! Something's happening in the-] Princess Celestia's transmission was lost as the blast of magic swallowed Sonic before everything went white…
(Phase 2)
When the light faded, Sonic found himself unharmed and floating right behind Rainbow Dash, Pinkie Pie, Rarity, Applejack, Fluttershy, and Twilight Sparkle.
The purple unicorn wasn't purple anymore but a golden yellow. Her eyes as well as her friends were all red. She wasn't a unicorn anymore but an Alicorn. Her mane and tail were now a bright cyan with white streaks. They both sparkled and shimmered like Princess Celestia's. She also wore her crown of harmony along with a golden necklace and hoofwear.
The rest of the ponies were all a shining silver but they all had different manes and tails. Rainbow's was still rainbow but appeared and moved as if it was made of fire. Rarity's was now a dark blue and slightly drooped but rolled up at the ends. Pinkie Pie's once frizzled pink mane was now yellow and each puffy curve became more spikier towards the back. Fluttershy's was now a forest green and became more curled and swirled than usual at the tips. Applejack's once blonde mane and tail was now orange. The spikes of hair at the ends of her mane and tail were more sharper and longer and her hat was absent.
Sonic stared in amazement at the supercharged ponies in front of her.
Twilight smiled. "Guess you're not the only one who can become supercharged." she said.
Pinkie nodded. "And besides, we're doing this together, right?"
"And perfect timing to ask that cause look who just showed up!" Rarity said, pointing to Nightmare Moon who was now alongside the Egg Shrine.
Sonic nodded. "I'll take care of Eggman while you handle the princess of darkness over there!"
The girls nodded.
"Let's do it!"
Sonic zoomed off to the mech, leaving Twilight and the girls to face Nightmare.
Eggman was shocked. "But how...This can't be! How?"
Sonic grinned. "It was a shocker for me too! Now where were we?" he rhetorically asked before ramming the cockpit.
Meanwhile, the mane 6 was in a head to head battle against the mare in the moon.
"You may have the power from the Chaos Emeralds but that won't stop me! I WON'T be vanquished so easily this time!" she exclaimed.
Twilight frowned. "Well we won't give up so easily either!" she said before firing a blast of magic at Nightmare.
Fluttershy nodded. "Just like Sonic, we'll never give in! Not until you're through!"
Nightmare Moon growled. "If that's the case, I'll just have to go all out on my magic!" she then summoned a meteor shower to rain down upon the 6 ponies. Some hit but not enough to weaken them.
(Phase 3)
After a few more boosts and homing attacks on the cockpit, the Egg Shrine was beginning to smoke and spark.
Orbot checked the status once more. "Our backup energy levels are fluctuating and things aren't looking too good boss."
Eggman slapped his robotic henchbot. "You shut up! I still have one last trick up my sleeve! Nightmare Moon, let's exterminate these rotten little delinquents once and for all!"
Nightmare Moon flew over to Eggman's side and began charging up every last bit of her magic left in her body. The hole on the bottom half of the Egg Shrine began charging as well.
Twilight and the girls assumed formation and readied the Elements of Harmony. Sonic flew over and positioned himself in the center of the circle as they charged up energy.
Eggman screamed with rage. "I've just about had it with you hedgehog! Prepare to be annihilated into nothing!" he yelled before punching the last button on the control panel. Both Nightmare Moon and the Egg Shrine fired their combined power.
Twilight and the girls had reached their maximum potential before blasting away. "NOW SONIC!"
Sonic boosted full speed towards the mech now joined by the blast of harmony from the girls. Both Super Sonic and the blast of harmony turned into 1 attack before the two forces collided!
Dr. Eggman could see that Nightmare Moon was slowly losing her strength. "What? I'm not giving up yet! All systems! Full power!" he yelled before thrusting the last lever forward. Eggman's power was greatly increasing, pushing both the harmonic blast and Sonic back to the girls.
Sonic struggled to overpower it but found himself making no progress. "C'mon Girls! Give it all you got!" he encouraged.
The girls mustered up every ounce of strength left in them and suddenly broke right through Eggman and Nightmare's energy beam!
"RAH!"
Sonic smashed right through the Egg Shrine's once invincible body before the harmonic blast engulfed both Nightmare Moon and Eggman.
"No! This can't be! My magnificent plan ruined!" Eggman screamed as he, Orbot, and the mech vanished, sent back to mobius where they rightfully belong.
"NO! Not again!" Nightmare Moon wailed as the harmonic blast swallowed her and purifying her. All her thoughts and emotions of evil were destroyed as she reverted back to the regular princess of the night, Luna.
