There's three of them?

Silver World

The Thorndykes Shadow, and his friends were in Chuck's lab watching the news.

"After the explosion on Prison Island, an emergency search team searched for survivors. Fortunately, the team now reports that everyone made it off the island safely." News Reporter said and everyone sighed in relief.

"I told ya not to worry. Chris must be okay." Shadow said.

"But if he's not on Prison Island and he's not here..." Amy said then gasped seeing Silver. "Silver must have taken him to Eggman!" she said and Tanaka nodded.

"In related news, authorities are still searching for Shadow the Hedgehog, who is-" the news reporter said.

Ella turned off the TV. Everyone was dumbfounded. Shadow stood up.

"I'm gonna go find my friend Chris." he said.

'And maybe see what Sonic is doing with Silver.' he thought.

"But the police are looking for you." Amy said.

"Don't worry." he said and took off.

"I hope Shadow doesn't get caught again."

"If we all search, perhaps we can find Chris." Tanaka said.

"Where should we look? Silver probably brought Chris to Dr. Eggman's secret base. But we don't have any idea where it is." Tails said.

"Tails has a good point."

"Well, if we're gonna find Chris, we'll have to find that base." Amy said.

"Then let's start looking right away!" Cream said.

"Chao!" Cheese said.

In the desert Knuckles stopped running.

Suddenly the ground shook, throwing him to the ground. He stood back up and saw smoke rising in the distance.

"Sounded like a rocket." he said and ran up a sand dune to see Eggman's pyramid base, and smoke rising from it. "Eggman's base..."

Meanwhile Chris was on a space station of some sort looking out the window.

"Whoa... It's hard to believe that I really traveled into space." he said turned around to see Silver behind him. "And we're inside a space station?"

"We call this place Space Colony ARK." Silver said.

"I never heard of it before."

"It was built fifty years ago by Professor Gerald Robotnik. It's been kept... secret." Silver said and looked out the window again.

"Wow, a secret space colony!" Chris said and turned back to Silver. "I wonder if I'm the only kid who's ever gone into space."

"You're not."

"What? Then who was?" Chris asked as Silver appeared conflicted, but didn't answer. "Hey, you know what? You look a little like my friend Shadow and his friend Sonic. Are the three of you... related?"

Silver's penetrating gaze caused Chris to tremble. However, in Silver's vision, Chris' reflection in the window changed to an image of Maria.

"Maria." he said to himself.

'Why do those names sound so familiar and why do they look familiar to?'

Silver saw himself, two other hedgehogs, Maria, and Professor Gerald fleeing from several soldiers.

"Stop them! We can't let them get away!" a Soldier said.

Then he saw one of the two hedgehogs in an escape pod as Maria ran up to a control panel.
