Depending on what character you play as, they each give an awesome rebuke to Void midway through the story.
Void: The Precioustone will shatter if I touch it. Maginaryworld... My world... The world of my dreams... Sonic: Hey! I'm not gonna let you do that! This world does not belong to you. It belongs to everybody. It's the world of everyone's dreams! Tails: Stop! This is a world... A world of everyone's dreams! I'm not going to let you have your way! Knuckles: Don't think you can have your way! I've got something to protect... You can't just come and take it away! Void! I'm not going to let you do this! Amy: Lumina! Don't give up! Void! You... You... You're not going to destroy everyone's dream... My dream!
The FMVs after each board is cleared show the worlds returning to normal.
