Smashing Shadow's face in multiple times with a super homing attack was quite satisfying! They developed a strategy where Knuckles and Tails would each occupy one arm, disabling Shadow's blocking ability. Then, it was a straight hit to the gut or face, whichever Sonic felt like hitting more.

His armor showed signs of cracking, but just as Shadow looked like he was ready to lose, a massive burst of red energy surrounded him, shattering his upper armor and sending shrapnel into the heroes - his Chaos Blast had just been used, now supercharged with the energies of the pure Chaos Force. All three heroes were blasted to scattered parts of the void, Shadow chuckling as he saw their super auras dissipate.

Shadow paced slowly towards Sonic with a chuckle, placing a foot upon his chest as the blue blur tried to stand back up... Shadow steadily kneeling down, applying more pressure to make breathing more difficult.

"You three never stood a chance, even with your powers. It is time for the old heroes to be replaced by the new..." Sonic looked daze as Shadow summoned an orb of red energy... he was debating whether to enslave Sonic or just eliminate him. Tough choices!

Then he felt Sonic grasp his foot, futilely trying to lift it up, "I'm... not... giving up.." Shadow was amused at his efforts, and formed a Chaos Lance... he would enjoy impaling him like a shish kebab. But just as he was about to end the hero's life, a voice spoke, Shadow looking around for the source; nobody but these four could be here!

"The servers are the seven chaos..." Images of the seven emeralds were seen all over the room.

"Chaos is power..." Now, there were images of the raw destruction every super being since the dawn of Mobius had wreaked.

"Power is enriched by the heart..." It showed people, villain and hero alike, using their desires as a conduit for chaos energy, making it far stronger.

"The Controller is quick enough to be where he is needed." Sonic saw a blue aura surround him, to his surprise.

"The Controller is intelligent enough to know what is needed." Tails was likewise, surrounded by a yellow aura.

"The Controller is powerful enough to do what is needed." Knuckles was surrounded by a red glow...

Shadow was blown back as energy waves unlike anything he'd ever seen hit him from seemingly nowhere, watching as the three heroes dissolved into spheres of their color, all converging on one point... Said point released a bright light on par with that of the Sun!

Shadow's jaws gaped as he saw the light vanish...

<pic goes here>

"The Controller is the one who serves to unify the Chaos!" This new figure, made from the talents and hearts of the three heroes, spoke. "And now, we shall see who has the right to be the Controller!"
