Siren (Wildstorm Universe)

Siren is a member of The Freaks, a group of villains who have clashed with Gen 13 a few times. Siren's body is entirely made of water and she has a mesmerizing voice, which she can use to hypnotise others.

She and the other Freaks were defeated by Gen 13 several times, and most recently, Siren was left in a state of freezing as she had no heat around her, causing her body to decrease in temperature to the point of freezing.
