Lightmare

Lightmare is Lord Sidewinder's most loyal servant, but is willing to question him when he makes poor decisions, as shown when she says "I told you it was folly to trust this demon," when the crimelord is betrayed by Super Sonic. She seemed to fear for his sanity when he became obsessed with usurping the powers of Super Sonic. She has the ability to confront people with their greatest fears through use of her Nightmare Boxes, often freezing them in place or rendering them unable to fight, proven when she made Sonic think he was blind in a dream and trapping Mighty the Armadillo in an invisible cage. She also seems to have the ability to teleport in a cloud of smoke. When Lightmare first appeared, her white robes and mask made her look like a man, but during a battle with the Chaotix she revealed that she was, unbeknownst to Sidewinder, her leader's daughter.

Lightmare has a blue body, white eyes and wears a white hudded suit, yellow shoes and various gold rings and chains.

She is believed dead following the destruction of the Special Zone.
