Sonic the Hedgehog CD

The only Sonic game released for the Mega CD, from 1993. Set on Little Planet.

"'For one month out of every year, a tiny planet appears in the skies above Never Lake. The mysterious Little Planet is home to seven miraculous gems that control the passage of time. When these Time Stones awaken, deserts revert to jungles and polluted waters become pure again. Intrigued by the unusual power of these stones, Dr. Eggman sets his sights on Little Planet. As soon as it appears in the sky, he chains it to a nearby mountain and, utilizing the planet's lack of boundaries on time, conquers the past so that he controls the future."

"Sonic, meanwhile, is on his way to Never Lake, completely unaware of Eggman's latest ambition. Our blue hero arrives on the shores of the lake and is shocked to see the legendary Little Planet chained to the local terrain. It doesn't take him three guesses to figure out the perpetrator of this deed, so he dashes up one of the chains to free the planet and throw a wrench into his rival's latest scheme. Unfortunately, Eggman has been clued in to his enemy's arrival, and preparations have already been made."

"Meanwhile, a young girl hedgehog named Amy Rose (aka Rosy the Rascal) is lured to Little Planet by a card reading that told her of a destined encounter with Sonic. Once there, Amy becomes the perfect target for Eggman to make sure he's got Sonic's attention and to show off his latest, most sophisticated creation to date: Metal Sonic. This robot duplicate of our hedgehog hero was designed to match Sonic's every move and even surpass his own namesake speed. This deadly new rival kidnaps Amy in front of Sonic's very eyes and escapes with his prize to Eggman's base.'"

"'A World That Defies Time!" "'Sonic, where are you going now?'"

"Sonic the Hedgehog looked over his should at Amy, the young hedgehog who was racing hot on his heels. 'To Never Lake.' he called back."

"'Why Never Lake?'"

"Sonic slowed down a little so he could explain. 'Ever heard of the Little Planet?'"

"'Isn't that the tiny world that orbits around Mobius?' Amy asked. 'The one with the special stones that alter time and change everything around them? I heard that the planet's full of places that are completely ignored by the passage of time!'"

"'Yeah. On the last month of every year, the Little Planet appears over Never Lake. It's that time now and I'm going to check it out. I bet space travel will be full of excitement!'"

"'Knowing you, with all those Time Stones there, I bet you'll try to outrun time itself!' Amy sighed in adoration. “Oh, Sonic!”"

"Sonic didn't reply. He just smiled, eyes gleaming."

"They left the Mountings and arrived at Never Lake. The Little Planet was there as expected. But something was wrong. Where there should have been tall trees and bright flowers, there was nothing but dry sand and jagged rocks. The Little Planet was tethered to a rock with a huge chain, and its surface was covered with twisted, gleaming metal."

"'What in the world happened here?'"

"Before Sonic could reply, something whooshed over them. Amy shrieked as she was snatched up, and she and her captor vanished in a blue streak of light!"

"'What the- AMY!'"

"It didn't take long for Sonic to realize what had happened."

"'This has to be Dr. Robotnik's doing!'"

"Indeed it was! Upon discovering the location of the Little Planet, the evil Dr. Robotnik and his robot cronies had immediately set about converting it to a giant fortress. He'd seen Sonic ap-proaching and had dispatched his prize creation, the Metal Sonic, to grab the girl and lure his arch enemy into danger. 'How convenient!' Robotnik crowed, bouncing about like a malicious rubber ball. 'This time my scientific expertise will crush you! Then once all the Time Stones are in my hands, I'll be able to manipulate time and conquer the world! HOOOO, HO, HO, HO!'"

"Sonic stood on a rock and though. Robotnik had control of the Little Planet. He had Amy, and soon he would have the Time Stones... But not if Sonic got to them first! His adventure on the Little Planet was going to be more interesting the he'd anticipated!'""— Sonic the Hedgehog CD UK instruction manual, Sonic Retro"
