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.

By the time Heroes kicks off season three, babies will have been born that were conceived after the season two finale but arrived in time for the season three premiere. That's a long wait by anyone's standards. Anyone except David Chase anyway. It's not as bad as all that though. NBC has seen fit to commission the web series, Heroes: Going Postal to make that wait just a little easier to take.

The series kicks off next Monday on NBC.com, and they've started the hype machine up this week with a trailer. The new character you see in the picture is Echo DeMille. He's a mild mannered mailman, with a secret. But as the trailer tells us, sooner or later, secrets will kill. The three part series is made by the same people behind the show and new episodes will appear on the following Mondays. It's unclear what role, if any, the regular heroes will play in the web series, but there is a familiar face that pops up in the trailer. See for yourself, after the jump.
