Eggman's jail cell
Vector: Then who was it? Who locked you up here for trying to conquer the world?
Dr. Eggman: It was...
A vast thunderstorm is raging in Eggman's fleet. Team Sonic, Team Dark and Team Rose converge on Neo Metal Sonic, who is standing at the top of a tower.
Neo Metal Sonic: Hmmhmmhmmhmm... All living things kneel before your master!
Neo Metal Sonic creates an electrifying plume of light from his palm which blows up the tower. Team Chaotix join the others just in time to witness him undergo a transformation, and the teams watch on in horror. In a vortex of bright light and smoke, Neo Metal Sonic attaches parts of the destroyed tower to himself and transforms into an immense metallic beast known as Metal Madness. Metal Madness lets out a deafening roar.
Dr. Eggman: Metal Sonic has finally transformed!
An enormous horde of panicked Egg Pawns make a hasty retreat to escape Metal Madness.
Sonic: So that's Metal Sonic?!
Tails: Don't you remember Sonic, you faced him and Shadow in their super forms when we were in that Meterax Base.
Sonic remembered but ever since that big flash of light hit the universe Sonic and several others memories were colliding with one another.
Dr. Eggman: It's useless! Metal Sonic has combined your data with the power of Chaos and is super strong! We can't defeat it! Aargh... if only we had the seven Chaos Emeralds!
Just then the Sinistars speakers reached the large group.
"Your wrong doctor, there's eleven Chaos Emeralds. Matter of fact. . . it's OVER NINE THOUSAND!!" Joseph said on the intercom of his massive vessel which covered most of the remaining Egg fleet.
They do indeed have the Emeralds! Cream pulls out the yellow Emerald and shows it to Eggman, and her comrades follow suit: Big has the purple one, Rouge has the white one, Omega has the green one, Sonic has the blue one, Espio has the red one, and Charmy has the cyan one. Joseph comes down from the Sinistar and shows four additional Chaos Emeralds that nobody even knew existed: the pink, orange, black, and brown chaos emeralds. Eggman is stunned at the sight of them.
Dr. Eggman: What's this? But how? Even with the Emeralds' power, our chances for victory are slim. It would take a miracle!
Sonic: Just leave that to me, Doc...
Amy: Sonic, no!
Tails: I'm going with you, too!
Sonic: Tails...
Knuckles: You can count me in, too.
Sonic: Knuckles...
Shadow: Okay guys, we'll buy you some time. That way you can use your super powers.
Team Dark, Team Rose and the Chaotix non-verbally affirm that they'll fight in the upcoming battle. Tails and Knuckles stand by Sonic's side, and he turns in a circle to address all his comrades at once.
Sonic: Okay then, let's get ready to do this. We'll show that creep the real super power of TEAM WORK!
With Sonics motivational speech, the heroes went off to fight Metal Madness.
