The sky blue hedgehog was standing at the peak of a mountain near Never Lake. He was admiring the beauty of Little Planet, a moon that only came around once a year. It seemed so long ago since he had gone there to save his friend Amy from the clutches of Dr. Robotnik and his robot, Metal Sonic. A lot had transpired since then. He had met his best friend, a two-tailed fox named Miles, whom he nicknamed "Tails". He had gained a new friend, Knuckles the Echidna, guardian of the Master Emerald, who had been tricked by Robotnik into believing Sonic was the bad guy, only to realize it at the end and team up with Sonic and Tails in order to stop him once and for all. But Robotnik came back. He always does. He teamed up with his future self to bring both Sonic and his future self to their doom by taking things from his past and future. After the adventure in time, Sonic had returned back to his home and everything started returning to normal. But then he saw in the distance, an obese man in a hovercraft flying to Little Planet. No, not again. Robotnik had already tussled with time twice, why was he going to bother again? The hedgehog stood up. He knew what he had to do.
He took a leap in the air and rolled down the mountainside to gain enough momentum to make the jump. As he rolled up and off the slope, he gained just enough air to land within Little Planet's gravitational pull. He adjusted himself in midair to land feet first on the ground. He hit it with a thud and took in his surroundings. Palmtree Panic, perfect. He looked around more and saw Robotnik's machine waiting. As he was about to confront him, Robotnik pressed a button in his cockpit. Suddenly seven mystical gems came up from the ground and surrounded Sonic. The Chaos Emeralds? No, it couldn't be those, the gems weren't the right shape… Sonic gasped. Of course! The Time Stones! Just as Sonic realized this, the gems spun around him so rapidly that Sonic suddenly found himself in a transitional void. Of course, this was Robotnik's plan. He was going to trap him in another time so he could take over in the present. Sonic closed his eyes and braced himself for the impact of wherever – and for that matter, whenever, - he was going to end up.
A yellow fox stood, cowering, in a desolate ruined city. His best friend and admired hero, Sonic the Hedgehog, had been trapped in another dimension for many years and Dr. Eggman had taken over the world with the help of his baddies, the ultimate robot clone, Metal Sonic, the 4,000 year old water god, Chaos, the leader of an ancient Zeti tribe known as the Deadly Six, Zavok, and the black hedgehog he had once thought a friend, Shadow. Tails may have gone through a lot, but he had never been more frightened than that very moment. He just couldn't go on after his best friend had been trapped forever, and it was right now that he was being confronted by Chaos. Off guard and with nothing to fight with but his fists and a tablet, the fox, named Tails, was scared to death. Possibly out of desperation, he called for help from his long gone friend, and just then, a portal opened.
Of all the places Sonic expected to end up, stomping the head of a water monster in a desolate ghost town was not one of them. He quickly jumped off the puddle and landed in front of a familiar face. His eyes widened as he saw the future version of his best friend, Tails.
"Woah…" said Tails in awe. "You must be that Sonic from the past, right? But how?" Sonic reached out behind him and pulled out one of the gems that brought him here before realizing that he didn't have the rest. Tails examined the gem for a moment and then opened his eyes wide as he came to a realization.
"Little Planet?" he asked. Sonic nodded his head in confirmation. "I knew it." Tails said. "Come on, Sonic, I need to bring you back to the base. You might be a key in figuring out this multiverse-sized puzzle."
