It had now been four years since Sonic left and Shadow would watch the news and read the paper when he's in it. There hadn't been another part of the prophecy done since Team Sonic was created and he was hoping that another part would be soon.
Team Sonic was fighting Eggman as usual but having a lot of trouble.
"I have an idea of how to beat him this time." Knuckles said.
"What?" Tails asked.
Knuckles looked at Sonic.
"The seven Chaos Emeralds. If you put them together you transform into Super Sonic in your case."
"How?" Sonic asked.
"Umm, I think you just need to focus on your Chaos and they'll come."
"OK, I'll try." he said and shut his eyes focusing on his Chaos.
While he did that he felt Chaos comeing close.
"You got them!" Knuckles said. "Now just shut your eyes, focus on your Chaos and they'll get in you what you need."
Sonic nodded, shut his eyes, started to go up and felt strength get in him.
People watching were shocked at what he's doing. A sixteen year old using the seven Chaos Emeralds.
Then he was yellow, orange eyes and his fur up.
After that he opened his eyes and saw he was a different color.
"OK then. Well, let's see what happens." Sonic said and looked at himself.
"How and what are you going to do?" Eggman asked.
Sonic thought for a second then saw the day he left.
He watched Shadow raise his arm and open his hand.
"CHAOS SPHERE!" he yelled and aimed at a Swatbot and got it.
"That's it!" he said and focused and raised his hand. "CHAOS SPHERE!" he yelled and got most of it.
Everyone gasped.
"How?" Eggman asked.
"Did you forget Shadow can use them without a Chaos Emerald? The fight we did when I left I heard him say Chaos Sphere and remember him teaching me them in case I ever start doing it. I can use them with a Chaos Emerald but don't use it that often." Sonic said and raised his hand again. "CHAOS CONTROL!" he yelled and got every Swatbot left.
Then he flew over to Eggman, kicked him hard and he was gone.
Sonic smirked, went down and let them out.
"Man that felt weird!" he said and the Chaos Emeralds were gone.
"You OK?" Tails asked.
"I'm good. Tired but good."
"Let's go and you can get some rest." Knuckles said and they to Angel Island for the night.
The next day Shadow was at home about to read the paper when he saw a picture of yellow Sonic and his quills up.
"He remembered what I taught him and can do. He will have the ability to use the seven Chaos Emeralds." he said. "Part four complete. One more and then we'll be together again." he said.
