Misty-Re

The Dark Presence Undercover Spy or Misty-Re, is a female Echidna and member of the Dark Presence, possibly in the Dark Eyes faction. She infiltrated Castle Mobius in 3265 by getting a position as a maid and revealed herself in 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.
