Part 1 Introduction: Tails Dies
Aboard the space colony ARK at the part where Robotnik is about to blasts Tails into space:
"So how did you know that it wasn't the real one?" said Sonic. "Because you just told me hedgehog." replied Robotnik. "Sonic you dumb sack of worthless fur what have you done, way to go you just ruined the whole plan, I hope you are satisfied you have just doomed the planet to rule under crazed man!" Tails yelled.
Sonic didn't know what to say Tails had never treated him like that he felt himself anger and he shouted to Robotnik, "better tie his tails together before you launch him so he can't break out and fly outta there" Robotnik sneered, "Great idea Sonic, thank you for telling me, maybe you aren't so bad after all." Robotnik's Eggwalker walked up to the capsule and he opened it slightly. Robotnik told Sonic, "Roll the emerald out and don't try anything funny or Cream gets it!" Tails reluctantly rolled the Chaos Emerald out to Robotnik who threw it to Sonic who wasn't expecting it and didn't catch it so it shattered on the floor. Sonic was flabbergasted he had just ensured that Robotnik would take over the world, what had he done, he was evil!
Sonic yelled at Robotnik, "You'll never get away with this Robotnik." Robotnik then gave a curt wave to Tails before saying, "Well Tails it's been years now that we have been in this struggle but it looks that I have come out on top after all. I have to say Tails I really will miss you, I will indeed. You were an admirable adversary, but know I must say my final goodbye, so farewell, good luck on the other side Miles Tails Prower." And with that he pushed the fire button and his longtime adversary was no more.
Sonic was speechless he had no idea what he had just done he had just gotten his best friend killed. Cream sagged to the floor weeping and Robotnik began to laugh. Sonic thought that he was pure evil even though it wasn't true. He just sat in the Tornado for what seemed an eternity as Cream cried and Robotnik laughed. Finally Robotnik almost sarcastically said to Sonic, "You know what, you aren't so bad you should come with me and help me flush out the rest of Tails's horrible friends so that my empire will go unchallenged. Sonic thought to himself, "The planet is already doomed and I've already destroyed my life why not?" "Yes, I will" he said weakly. Robotnik was shocked "Really?!" "Yes, but I think I should rule and you be out my way forever, Robuttnik" Tails replied. Sonic heard Cream shriek and Robotnik was shocked, but replied, "Hey Sonic, I thought we had a deal." Sonic smiled evilly and said, "Change of plan Robotnik, I will rule and you can either die or serve me, but once the world is taken over, I will get rid of you, understand?" Robotnik weakly replied "Yes sir." "Good, now go and help Shadow and Rouge prepare the Eclipse Cannon so I can attack this planet." Sonic said laughing evilly.
So things continued on like this Sonic took control of the world and Robotnik became his Second in command. Sonic drove fear into the hearts of world leaders with his mighty Eclipse Cannon until all the countries of the world were under his tyrannical rule. Sonic found himself enjoying what he was doing and felt that he couldn't turn back. Over the years friends drifted apart and grew older, and some of Tails's old friends lost contact. Sonic himself grew older and more evil as he began to do more public things that Robotnik considered himself too old to do. But as soon as Sonic got to full power, he killed Robotnik in the middle of Station Square where everyone saw. Because of this, Sonic became famous as being the worlds most powerful tyrant and was now considered the most hated person in the world…
