Synopsis
Sonic is trapped beneath Aquarius’ waters, and Amy wants to dive straight in after him; the others hold her back while they look for a better plan. Knuckles finds one: pour the Master Emerald’s energy into the Sonic Driver and cut off the Final Mova’s power, while Shadow and the Chaotix fend off its attacks.
The shot destroys two of the dragon’s three heads, Black Narcissus and Pale Bayleaf, and leaves Dark Oak’s barely moving. The price is high: the Master Emerald shatters into powerless shards, and the Metarex have drained the Chaos Emeralds too. In the middle of the battle, Eggman tells Chris something shocking.
Deep inside the planet, Sonic is dreaming of a world after the forestation, battling sand monsters and grasping plants. Amy spots him and plunges in, and as the two sink, a strange sphere shields and heals them until Chris pulls them out in the Hyper Tornado. Then the planet itself starts to shrink into a giant seed.
