Heroes introduces a couple of new heroes/villains in their webisodes. Echo DeMille has the gift of sound - the roar of a lion (I bet he's a Leo!) and the Constrictor looks like that weird albino guy from the Twisted Sister videos (or was it Motley Crue?)
In any case, these webisodes are meant to whet your whistle for the upcoming season of Heroes: Villains but all they only make me long for is the time spent watching them back... Someone find Hiro!
