My take on what would happen if the plan had hit its intended target. I own nothing! Enjoy!

"This park is huge" Sonic pointed out as he and Tails walked to the next generator

"Yeah" Tails agreed "Eggman could be anywhere"

What they didn't know was that said someone was hiding behind the very generator. He was in his Egg Mobile which now had a gun and two large tubes filled with a purple substance

"Indeed I could" Eggman said to himself, "But I'm right here behind this generator"

Eggman waited patiently for the right moment.

"That's it hedgehog. Stand there and be a good little target"

He pressed a button and his machine activated, giving off a loud hum as he flew from the generator. Sonic and Tails easily noticed the humming, both looking in the same direction to find the source.

"Tails, is that you humming?"

"No, I thought it was you"

Being extra stealthy Eggman snuck behind the two, aimed, and with the press of a button Sonic was hit by a glowing purple laser.

"Sonic!" Tails yelled

Sonic yelled out over him before collapsing to the ground. Seeing this Tails took to the skies with full intention on taking Eggman down. But before he could reach him he was suddenly knocked down by a stronger force. Tails hit the ground with a loud thud. He looked to see what had hit him and was stunned.

It was Sonic who had knocked him down!

But Sonic wasn't himself. His eyes were dull and half open as the beam continued emitting the purple substance into him. Sonic held his arms, unmoving, to protect what once was his enemy. Tails dared to get closer

"Sonic? It's me, Tails!"

Eggman laughed "I'm afraid he can't hear you now"

"What have you done to him?" Tails demanded

"Me? I did nothing at all. Unless shooting him with my mind control beam that runs on alien energy counts as doing something to him. Does it?" Eggman asked smugly, stroking his mustache.

Tails took a second attempt at charging at Eggman; and was met with the same results.

"To get to me you're going to have to go through your best friend" Eggman informed before laughing

Tails stood in front of his once best friend. To get to Eggman he had to go through Sonic. But Sonic was stronger and faster than him. This was going to be difficult.

Eggman watched amusingly as Tails made several more attempts to get past Sonic. With each one ending with failed results

"This turned out just as I had hoped. And I only used a small prototype"

Tails got up from the ground once more and looked at his entranced friend.

"You know what would make this better?" Eggman asked, earning a glare from Tails

"I think that the only way to make this better, would be to have you two fight"

Taking in the order, Sonic glared at Tails. Tails started to back away, but as he did Sonic started to get closer. Tails couldn't even get past Sonic; a fight was the last thing he wanted to do right now.

"Sonic please, you don't want to do this. You have to fight Eggman's control" Tails pleaded

Sonic growled at him, raising his fist for the brawl. But before he could deal a blow he suddenly collapsed. Eggman leaned forward in shock while Tails attempted to wake his friend.

"Sonic? Wake up! Are you okay?"

Sonic opened his eyes and supported himself on his knees.

He groaned "Wha? What happened? And why is my nose tingling?"

Tails smiled "Sonic! You're back!" he said as he hugged his friend

"Yeah but where did I go?"

"Lousy cheap alien energy" Eggman began repeatedly slamming his hands down on the machine

After several slams he looked back and saw that he had run out of the purple substance

"Ran out of juice" He acknowledged "Well, I'll get more. Lots more! And then I won't just control one little punk, but the whole universe"

The two finally turned their attention back to Eggman, who continued talking

"In the mean time, enjoy the park. I'll leave you your own private tour guide"

Eggman left in quick haste. When he was far enough a giant desert boat rose up, with robot candy pirates looking for a fight.

Sonic laughed "Pay up Tails" he said as he turned toward him

"I told you he had an evil plot, coming here was a good idea. There it is straight from the horse's mouth"

"Uh, we didn't bet" Tails reminded

"Dang" Sonic said in defeat, walking away as the two shared a wave.
