Final Fortress, somewhere in Antarctica

A battle was won not long ago, by the power of (I shudder as I recall it) Friendship and Heroes. But no more my filthy organic doppelganger, now I am in charge. For months, if not years your silly little smirk has haunted me for all that time, now it is my turn to laugh. I do have to admit though, you put up a graceful fight, and it amused me. But do you the most important thing? I enjoyed it...
"Stop it..."
Now why would I do that? I am simply repaying the years of angst and pain you have caused me...
"Just stop it..."
That day, the day I returned for the final time. What did you feel? Answer me that...
"Like I wanted to shove your damn processor up your metal behind, what else?"
Oh yes, you showed hatred. You showed fear, terror even...
"I wasn't scared of you..."
*Spins round* Yes, but Amy was, and Shadow, even Omega. But you know who was experiencing the true meaning of fear?
"Stop it..."
Come on, you must know...Think of the number two...
*Struggles in chains* "Shut up!"
Come on! You know you want to say it!
*Stops* "Tails..."
Knew you would get it! But enough of the games...*presses button on arm* It's time for the fun to begin...
*Hatch opens on floor; a bedraggled body emerges wrapped in chains.*
...for six years I've had him here. Not a single moment of sadness for him, I've kept him amused for all that time...
"T...Tails?"
*giggles insanely* "I can see the moon! And the stars! Oh, I have not opened my eyes for so long!"
"WHAT DID YOU DO TO HIM?!"
We may be copies Sonic, but my ideas of keeping someone amused differ greatly from yours...
*Walks over to Tails*Do you want to see my work, my own work?
*Pulls Tails' head up, a metal face is seen*
"That's not him..."
Oh but it is...When you ran from me he pleaded for mercy, so I gave him some...Think, Sonic, what is the most terrible thing to happen to a great mind?
"I don't...know..."
Oh, you're no fun anymore Sonic! The mind is constantly being plagued by insanity, I merely increased its effects...In short, I managed to resurrect him even better than before...
"Sonic, I see your death! Your beautiful death, the whole of the Chaos Universe will fall at your demise!"
That is something I'd like to see being backed up...
"Your death will come at the hands of an impostor, the shadow in armour! The ultimate killer! The moon will be dyed red with the blood of the innocent life! One will make the sacrifice to be told for all time!"
I can see that working nicely...
"Metal...What have you...done?"
I have finally won my counterpart! At last, my goal is complete! If you want to survive with me, you will need to be...upgraded.
"I'll never join you!"
Sadly, I wasn't asking...

G.U.N Headquarters, Manhattan
"Rouge! Have you located Sonic?"
"Not yet Shadow!"
*Turns to Omega*
"Have you searched everywhere?"
"Affirmative! There's no sign of him or Tails!"
"Keep checking! Use heat scans, X-Ray, anything!"
"Yes!"
*Turns back*
"Come on Sonic, where are you?"
"Shadow! There's a Radio transmission from an Anonymous Source!"
"Intercept it! Tell me who sent it!"
*Static screen flashes up*
Oh Shadow, you grow so fast!
*Everyone stops, fear grips the whole base*
"No, it can't be...We killed you..."
Body wise, but my intentional being survived...Besides, I've something to show you...ALL of you who opposed me!

Chaotix Resistance Movement, Canada
*Slams down fist*
"Where is he?!"
"Vector! I'm going as fast as I can!"
"If he's not alive I'm going to turn that Egghead so far inside out..."
"That's not helping Espio's decoding!"
"Speaking aloud Charmy!"
"You're both not helping!"
Allow me to assist!
*Static screen flashes up*
Hello Chaotix!
*Charmy tries to shut it down and gets electrocuted by reddish lightning*
Nuh-uh-uh, can't shut ME down!
"Vector...Charmy...Please tell me this is a nightmare!"
Oh stop worrying; I merely have something to show you...

Egg Carrier, Las Vegas
*Whirls hammer*
"Where is he?!"
"He just disappeared...!"
"I can see that, Eggman!"
"Amy! Calm down!"
*Cosmo pulls Amy off*
"WHERE'S SONIC AND TAILS?!"
"I don't know!"
Oh my creator...How desperate you have become!
*Nearest TV screen goes static*
"No..."
*Amy clenches her grip on her hammer*
"You..."
*Eggman fumbles for glasses*
"You...were destroyed! It's impossible!"
Oh yes! But I have succeeded where you failed! Watch and learn Dr. Eggman!

Final Fortress, Roboticization Chamber
Yes Ladies and Gentlemen! I, Neo Metal Sonic, have returned! And for the count, have experienced my greatest victory yet! I have captured and restrained Sonic the Hedgehog! You know, it is amazing what you can do with a huge fortress buried in the ice and some valuable data!
*We now see, Metal Sonic. His Neo form has upgraded to impossible levels, the wings from his Overlord form are attached to his back. Its claws replace his original hands, and a long spiked tail is seen from his wing connectors*
But enough talk! As you can see, Sonic is strapped to the machine (I use the term broadly) and as soon as I press this button, you will say goodbye to Sonic...
*Presses Button*
And hello to the new V3 model...Genocide...
