Back on Earth, the party was cut short as Sonic and Tails were the first to notice the sky turning a dark purple. Thunderclouds began to form and darken the once bright and blue sky. Everypony was beginning to worry before they turned to their only saviors: Sonic and the mane 6.
Princess Luna frowned. "Discord is still up there...and he is the one to blame for the sky's unnatural behaviour."
Sonic facepalmed. "I had a feeling this adventure was far from over." he sighed.
Princess Celestia looked up to the sky in worry. "I still feel the presence of the artificial energy left over from Dr. Eggman's machines. If Discord is able to absorb it, he'll use the energy to bring chaos to Equestria and thus could lead to his reign of anarchy much like what happened 1000's of years ago. Only far more worse." she explained.
Tails nodded before turning back to his friend. "We have to stop Discord now before he gets any stronger! He's probably starting to absorb the energy!" right after he finished, a chunk of the earth broke free and rose up!
Twilight frowned. "Yes he is! But how are we gonna get back up to the Death Egg when it's all the way up in space?" just as she finished, the nearby space began to distort and bend into a wormhole.
"Perhaps that could lead you into the doctor's base." Shadow said.
Sonic nodded before turning to Tails. "From the looks of things, I'd say he's right! I'm getting strong readings of the energy...though the wormhole itself is giving off weird levels of energy...as if they were signals from...something else. I'd be careful if I were you." Tails said, reading off of the handheld.
The girls nodded along with Sonic before approaching the wormhole.
All 3 Princesses stood behind them, wanting to share some information before the heroes depart.
"We don't know If our contact spells are strong enough to go through the wormhole so use extreme caution and try to remain together. This being a wormhole created by Discord himself, he may try to test your abilities. Good luck." Celestia warned.
The group nodded before turning to each other and sharing another nod. "Let's do this!" they shouted before entering the wormhole.
(Final Stage: Chaotic Rift)
As Sonic and the girls landed, the entrance to the wormhole closed, leaving nothing but abnormal space and time. The rift expanded into a pink/purple/magenta void which went on infinitely. The path ahead of the group consisted of floating chunks of earth, pieces from the Death Egg, asteroids, meteors, and even debris from Canterlot Castle. They were randomly arranged either scattered or as one huge platform with some full pipe loops here and there. The last few remaining badniks were present as well including Caterkillers, Buzz Bombers, Motobugs, Bat Brains, Egg Pawns, Crabmeats, Orbinauts, Spinners, Spikes, and Shellcrackers. All of them under the command of Discord.
Sonic and the girls wasted no time and ran forward, staying together as one group. They plowed through the hoards of enemies and outsmarted Discord's toughest puzzles and strategies. A mass shooting from Buzz Bombers and Egg Pawns? Twilight and Rarity would rely on stealth to take them out while Sonic dodged and homing attacked his way through, eventually both clearing the path to move on. Button on the other side of a large canyon? Rainbow Dash and Fluttershy could take care of that and count on Sonic to take out any aerial or side dangers. A submerged button hidden in a maze? Twilight's magic is always there to provide air and protection. A Manticore loose? Fluttershy is the perfect distraction.
With each other's abilities and the power of teamwork, they made it through and were one step away from facing the final challenge, the master of chaos himself: Discord.
