The Giant Eggman Robot thrust a fist into the ground, directly between Sonic, the Wachowskis, and the Emerald itself.

KROOOOOOM!

The ground shook with the force of the blow, but Sonic rose back up and made a beeline for the Emerald. He put his hands on it at last!

But when he opened his hands to inspect the prize, the Emerald shattered into pieces. Its power seemed to go dead.

“What am I supposed to even do with this thing?” Sonic called out.

Robotnik used his mech to set fire to trees in a wide circle around the hedgehog.
