File:Sonic X Episode 54 - Cosmic Crisis

Description
Cosmo explains the Metarex goals and the consequences of the planet egg's removal. Cosmo also admits that she's the only survivor from her group, which was eliminated by the Metarex. Knuckles does not trust Cosmo. Everybody (except for Knuckles, who's suspicious of her) agrees that the Metarex must be stopped and they decide to go into space to destroy the Metarex and to find the lost Chaos Emeralds. Luckily for them, Tails has just finished to build his new invention: a big flying fortress called the Blue Typhoon. His new ship has to be powered by the Chaos Emeralds. Chris thinks that they could use the Master Emerald. Knuckles initially disagrees, but with some female persuasion, (getting attacked by Amy, Cosmo, and Cream,) he finally agrees. At the same time, another Metarex is sent to the planet in order to destroy Sonic and the Blue Typhoon. A fight engages between the Metarex, Sonic and Knuckles. With the help of the Typhoon's primary weapon, the Sonic Driver (Sonic Power Cannon in the English dub), the Metarex is destroyed. The Blue Typhoon takes off, but it is followed by Dr. Eggman and Rouge.
