There's three of them?

Showdown in Space

Back on the viewport Chris struggled to stand once more.

"Please listen. It's true there are some bad people in the world, but most people are good. I know that you would agree with me if you only got to know them, just like Maria wanted to. Silver, please. Maria would want you to be friends with people." Chris said.

Silver was surprised at how much Chris reminds him of Maria.

In another flashback Maria was dying as Shadow was trapped in a pod.

"Shadow, please promise me... that you'll help people... and be... friends with them..." Maria said.

"Maria!" Shadow said as she struggled to move.

"I'm sure you'll be very happy down there, Shadow. I only wish that I could go along with you." she said.

Then they were on Earth.

"The world looks so beautiful from up here in space. But my grandfather says the people who live there have to face many problems." she said.

Then they were under an oak tree on Earth.

"That's why you were created. To help those people and to be their friend." she said.

Back to the Viewport Chris could barely stand. He fainted, and Silver caught him. A tear welled up in Silver's eye and Amy noticed it.

'Sonic, Shadow. I'm not the only one Professor created. He created all three of us.' he thought.

Then Tanaka picked up Chris.

"He was right about Maria. She did want me to help the people of your world." Silver said and smirked. "And I'm not the only one Professor made."

Meanwhile ten minutes remain, and Shadow, Knuckles, Bocoe, and Decoe entered a giant chamber.

"Up there!" Knuckles said.

Suddenly a giant lizard known as the Biolizard landed in front of them and roared, scaring the hench-bots.

"Calm down. I'm not gonna let that monster get a hold of the Master Emerald." he said.

Suddenly Silver was next to Shadow.

"Leave that thing for me." Silver said.

"Silver." Shadow said.

"You and the others take care of the Chaos Emeralds, and I'll distract it." Silver said. "And I remember you and Sonic. We stuck together in the beginning we'll stick together now."

Shadow hesitated and Silver glanced at him, and he finally nodded. Silver rushed forward and Spin Attacked the Biolizard, causing it to roar.

"Let's go!" Shadow said.

The four ran toward the reactor as Silver dodged the laser beams the Biolizard fired from its mouth. Shadow and the others carried the Master Emerald to the top of the reactor.

He struck the Biolizard with multiple Chaos Spears.

"I must remember... the seven Chaos Emeralds are the servers. Our hearts intensify their power. The controller serves to unify the chaos." Knuckles said.

"You can do it, Knuckles." Shadow said and Knuckles stretched his hands toward the Master Emerald.

"Master Emerald, I need you to help me. Please stop the Chaos Emeralds!"

Meanwhile, the Biolizard materialized several energy balls around its head before sending them toward Silver. He dodged several of them, then spun toward Biolizard, bouncing from ball to ball before landing the final hit on the prototype lifeform.
