Superheroes and supervillains, quirky characters, movie-quality effects and suspenseful plots with unexpected twists made "Heroes" the watercooler hit of the 2006-2007 TV season. It racked up eight Emmy nominations, including Best Drama Series, and attracted a huge following to its take on good versus evil.

"Heroes" has spawned a comi­c book, video game, Web serial and a spring 2008 spin-off called "Origins" while getting America -- and fans in nearly 150 countries -- hooked on the adventures of an indestructible cheerleader, a Japanese time-traveler and an exotic dancer with a very split personality.

Now, as its second-season premiere approaches (Sept. 24 on NBC), "Heroes" carries the pressure to match, if not outdo, its stellar freshman year. The premiere episode is titled "Four Months Later," segueing from the season one finale.

"I'm never 100 percent satisfied with anything, but I was pretty pleased that we were able to wrap up that much story and give ourselves enough of a blank slate to start the season with," says series creator Tim Kring.

But much was still in doubt at the end of the season one finale, including the fate of Peter Petrelli (Milo Ventimiglia) and D.L. Hawkins (Leonard Roberts). Kring won't comment on their status, but he does make it clear that there will be major shakeups in the lives of returning superheroes and a long list of new characters joining the "Heroes" universe.
