File:Sonic X Episode 67 - Teasing Time

Description
Sonic and friends come across a barren planet with 500 Chaos Emerald signals coming from it. Black Narcissus is inside, and sends a message to the Typhoon, a message that only Cosmo can understand. He then sets off fireworks, allowing Cosmo to escape to the planet undetected. Unexpectedly, Chris follows, but Narcissus captures both him and Cosmo. When Chris tries to escape with Cosmo, Chris is attacked and stabbed by Black Narcissus. Meanwhile, Sonic discovers their disappearance and comes to rescue them, and upon seeing Chris injured and Cosmo terrified, he enrages and becomes a darker, more violent version of Super Sonic thanks to the Metarex' fake Chaos Emeralds' negative energy, dubbed Dark Sonic. Dark Sonic then proceeds to destroy two Metarex robots Narcissus had prepared just for him for an "experiment" (Gold for strength and silver for speed). Suddenly, Eggman appears and has Decoe and Bocoe hold Narcissus down while Bokkun kicks him, dealing some damage. Chris and Cosmo are saved by Shadow while Rouge destroys the machine that makes the fake Chaos Emeralds. Sonic returns to normal. Sonic, Chris and Cosmo are reunited with the others and Eggman asks Black Narcissus he cannot go to Metarex team as The Blue Typhoon leaves the planet.
