*FWOOSH*
The sound of a sonic boom echoed through the air, as Sonic began to approach his top speed. He rarely ran that fast, but this time it was important.
Tails had been kidnapped!
Sonic leaped onto several tree branches, not staying on any one long enough for it to sag under his weight. He jumped onto Eggman's machine, and approached the caged Tails. Eggman completely ignored him.
Huh. This'll be a piece of cake. Sonic thought to himself, touching the cage's lock.
*BANG*
The cage, Tails included, surrounded Sonic in an instant. Eggman hopped out of the cockpit, and walked over to Sonic triumphantly.
"You! Where's Tails?" Sonic asked.
"Oh, don't worry about your friend… yet. I haven't laid a finger on him. I've learned my lesson from those good-for-nothing Zeti. Tails is not worth attempting to take."
"Oh, well, in that case…" Sonic turned to leave, before bumping straight into the cage.
"It's you I'm after. You've been a thorn in my side since the very beginning. But… you couldn't tell computer code from hexadecimal sequences. You'll be easy prey!"
Shoot, he's right. I'm gonna need Tails to get out of this one. It's not like Tails will struggle once he gets here.
"I know what you're thinking. Yes, Tails will be tricky to take care of. But I have a plan for that," Dr Eggman menacingly stated, pulling out a remote.
"Tails! Where's Sonic?" Amy asked Tails, as he returned from his test flight on the Tornado.
"Huh? I don't know… he was here when I left. Something must have happened since then."
"You were gone a long time, Tails… maybe Sonic went looking for you?" Knuckles suggested, walking in on the two. Tails sunk into deep thought.
"I've got it! Did Sonic take the Miles Electric with him?" Tails asked, his gaze on the mantel on which it was kept.
"We tried that. It didn't work," Amy sighed, holding up Sonic's Miles Electric. Tails pulled his own out. He placed his fingers on the touch screen, and began tapping it rapidly. He stepped outside, and the Miles Electric started beeping.
"He went this way. I'll be back in two tails!" Tails said, confident that he would succeed.
*BZZZT* *BUZZ*
"What? What happened? This thing's going haywire! But what could have caused it…" The sound of a helicopter's propellers sounded, and suddenly stopped. Tails looked up.
"Who are you?" he asked the odd fox who had made the sound.
"I? I am Metal Tails! Eggman got sick of trying to make you obey him, so he made me. My first orders? Destroy the defective model. Miles… you are going to die."
Metal Tails, as he called himself, raised his arm cannon. The half of his face that resembled a face grinned maniacally. The cannon charged its energy, and fired.
*KABOOM*
Tails didn't dodge in time, and was sent into the sky.
"That should do it. But just to make sure…" Metal Tails fired another shot. This time, a Buzz Bomber came out of the weapon.
"I want you to go in that direction, and find the defective Tails. Do not return without his body. I want to make sure he is very definitely dead."
*BEEP*
The Buzz Bomber flew off into the sky, tracing the trajectory that Tails would have made. Metal Tails shifted his tails back into helicopter mode, and flew off in a new direction.
Short, but this is merely a taster. Or a prologue. Our choice.
This sets up the villain and the original motivation. Several elements of this story will change by the second chapter (which is not done). Sadly, this means another story in which the interface is lying to you.
...Proves how much Sonic I know. I've got no signout for this franchise.
