INT. DR. EGGMAN'S LAIR - DAY
Sonic and Tails have finally tracked down Dr. Eggman to his lair. They are ready to face him once and for all.
SONIC: It's over, Eggman. It's time for you to leave this mortal plane.
DR. EGGMAN: Ha! You think you can defeat me? I am a genius, and I will destroy you.
SONIC: I'm afraid not, Eggman. I've come too far to let you continue your evil ways.
Dr. Eggman activates his latest invention, a giant robot that he plans to use to destroy Sonic and Tails.
SONIC: Come on, Tails! We have to stop him!
Tails and Sonic jump into action, using their speed and agility to dodge the robot's attacks. They work together to weaken the robot, until finally, they manage to destroy it.
DR. EGGMAN: No! This can't be happening!
SONIC: It's over, Eggman. You've caused enough trouble. It's time for you to go.
With a determined look on his face, Sonic approaches Dr. Eggman and challenges him to a final showdown.
SONIC: Do you want to leave this mortal plane peacefully, or do you want to fight?
DR. EGGMAN: I'll never surrender!
Dr. Eggman attacks Sonic, but Sonic is too quick for him. With a single spin dash, Sonic knocks Dr. Eggman off his feet and sends him flying into the sky.
SONIC: Goodbye, Eggman. May you find peace wherever you're going.
Tails and Sonic watch as Dr. Eggman disappears into the sky, never to be seen or heard from again.
TAILS: We did it, Sonic. We've finally defeated Eggman.
SONIC: Yeah, we did. And now, it's time to move on to our next adventure. Dr. Eggman orbits around Mobius, his body glowing as he gains speed with each passing moment. He's determined to take down Sonic once and for all.
DR. EGGMAN: I'll show you, Sonic! I'll take you down with me!
Suddenly, Eggman darts towards the planet, hurtling towards Sonic at an incredible speed.
SONIC: What's he doing?
TAILS: He's headed straight for us, Sonic! Move!
Sonic tries to dodge out of the way, but it's too late. Dr. Eggman slams into him at the speed of light, their bodies exploding into a shower of energy and light.
TAILS: NO! SONIC!
Tails watches in horror as the two greatest forces on Mobius are destroyed in an instant. The aftermath of their collision ripples out across the planet, leaving destruction and chaos in its wake.
TAILS: How could this happen? How could they both be gone?
Tails stands there, stunned, unable to believe what he's just witnessed. The loss of his friend and hero is too much for him to bear.
TAILS: Sonic... why did you have to leave me?
