NBC launched a webisode series called Going Postal to whet your appetite for the fall season of Heroes. Each week we'll get introduced to a new villain, their ability and their motives.

The first installment called "A Nifty Trick" features Echo DeMille played by Kiko Ellsworth (General Hospital, Dexter). Echo is a mailman with a secret ability that involves really loud screaming. An official-looking agent and a pale thug are after him.

Over the next few weeks we'll find out more about Gina (Rebeka Montoya), Constrictor (Mark Steger), Agent Howard (Brian Prescott), and Agent #1 (James Ryen). Gina is Echo's love interest (according to the site she doesn't have a special ability). And we meet Constrictor in this first video. You can probably tell what Constrictor's ability is just from the name.
