Ali Larter stars in NBC's award-winning ensemble drama series "Heroes" as Tracy Strauss, a smart, savvy, well-connected Washington lobbyist from Beverly Hills, Calif., whose reputation as an "ice queen" gains extraordinary significance after she manifests the ability to instantaneously plunge temperatures, create ice and freeze anything -- or anyone -- in contact solid. Recently, she championed Nathan Petrelli's (Adrian Pasdar) appointment to the U.S. Senate and stumbled upon an unknown, hidden family, including an identical sister, Niki Sanders, and nephew, Micah (Noah Gray-Cabey). "Heroes" follows the lives of ordinary people who discover they possess extraordinary abilities.

In February 2009, Larter will star in the thriller "Obsessed" opposite Beyonce. She recently starred with Milla Jovovich in "Resident Evil 3: Extinction," and in the independent films "Marigold" and "Crazy." Larter starred in the successful first and second installments of the "Final Destination" franchise, and opposite Reese Witherspoon in the hit film "Legally Blonde." In addition, Larter enjoyed a successful run on the New York stage in "The Vagina Monologues."

Making her feature film debut in the blockbuster hit "Varsity Blues," Larter includes among her credits "A Lot Like Love"; "American Outlaws," starring opposite Colin Farrell; "Jay and Silent Bob Strike Back" for writer-director-actor Kevin Smith; "The House on Haunted Hill," a remake of the original Vincent Price horror classic with Taye Diggs and Geoffrey Rush; and "Drive Me Crazy."

A native of Cherry Hill, N.J., Larter began modeling at 13 and traveled the world before moving to New York. She currently lives in Los Angeles. Her birthday is February 28.

As babies, Tracy and her identical sisters Niki and Barbara fell into the hands of the Company's Dr. Zimmerman, who injected them with the formula to produce synthetic abilities. Tracy didn't manifest her ability to freeze things until she had already earned the title "Ice Queen of K Street," while working as a political advisor for the New York's powerful governor, Robert Malden. Although it looked as if Tracy was the perfect helpmate to steer Nathan to the presidency and perhaps even become First Lady, Nathan turned against his former lover, making her the first target of his Building 26 team. Niki's son Micah helped Tracy escape, but when she realized the impossibility of regaining her old, "normal" life, she sacrificed herself to save him. Tracy froze herself, and Danko's bullet shattered her into a million shards of ice. But ice melts, and Tracy has now managed to reconstitute herself, drawn back to life by one diabolical thought: revenge.
