Speedy new character debuts on new season of NBC's 'Heroes'

"I had to go to this place and stand on a platform in my underwear," said Grant. "They turned it around and took photos of me. It felt like some sort of weird experiment. I imagine those pictures will end up on the Internet at some point."

Grant graduated from the University of Texas before moving to Los Angeles to pursue acting. Last season, she played sassy high school student Jean on NBC's "Friday Night Lights." The 26-year-old actress' short bleach-blond dreadlocked hairdo has become her signature. "Heroes" producers only trimmed her bangs for the role of Daphne.

"It's mine. It was like this," said Grant. "Basically, I dyed my hair for 10 years and at some point it turned into a big pouf, so I started dreading half of it and just letting it go. Every once in a while, I'll dye it to get rid of my roots. People hate it or love it. I'm actually not that attached to it, honestly."

Grant has mighty aspirations for Daphne's future on "Heroes."

"I hope to be in some battle with the other Heroes, whether it's with them, against them, whatever," she said.

The third season is titled "Villains," and will pick up immediately following the events of the second season, which was cut short because of the writers strike. Viewers will learn about the fates of several characters when the show returns in September, including who shot Nathan Petrelli.
