Misty-Re

The Dark Presence Undercover Spy was a female Echidna and member of the Dark Presence, possibly in the Dark Eyes faction. She infiltrated Castle Mobius in 3265 and revealed herself on 3267 when she gassed Silver the Hedgehog unconscious after flirting with him, and was then knocked out herself by King Sonic using her own gas-gun.
