Dania Ramirez, who played Callisto in X-Men: The Last Stand and has a recurring role on "The Sopranos," has been added as a regular on the NBC's hit series "Heroes." The show returns for a second season in the fall.

Ramirez will play Maya, a new hero whose powers are being kept under wraps.

"Heroes" extends Ramirez's relationship with NBC. This past development season, she co-starred in the network's drama pilot "Fort Pit."

Maya is one of four to five new characters expected to be added to "Heroes" next season, but her character might be the only regular one. The other roles, most of which are said to have international flavor, include a sexy boyfriend for Claire (Hayden Panettiere), a 28-year-old black mother, a surrogate for Niki's (Ali Larter) son and an Irish mobster
