According to Masi Oka, chapter three of Heroes - titled "Villains" - won't just be showcasing your basic evil character.

Everyone on the series will show a dark side.

"I think that you'll see a dark side of everybody, because being a hero or villain is very subjective," Oka said in an interview at the Television Critics Association's summer press tour. "Each human being has the ability to become a hero or a villain. It's the choices that we make every day, and that can be influenced by the things around us."

On the upcoming season, Oka's Hiro will be faced with a new personal enemy: Daphne, aka "Speedster," played by Brea Grant.

"She's Hiro's nemesis," Oka said. "And every time Hiro sees her, he calls her his nemesis. And she's great. She's very spunky. She's a speedster. It's kind of like Batman has his Joker; Hiro has his Daphne."

The actor added:

"Brea's fantastic. She came from Friday Night Lights. She's such a joy to work with. We had a chemistry test, and I loved working with her, and we have so much fun working together. Hopefully you guys will enjoy it as well."
