We're just two and a half weeks away from the series premiere of Heroes vs. Villains.

In celebration of the competition's 20th edition, the CBS reality show will feature 20 well-known, veteran castaways, pitting them against one another in a battle of good versus evil.

As we prepare for the first episode on February 11, the TV Fanatic staff is previewing each returning cast member. Last week, it was Rupert Boneham. Now: Stephenie LaGrossa.

Previously seen on: Survivor: Palau and Survivor: Guatemala
Occupation: Pharmaceutical rep
Heroic feat: In Palau, Stephenie was the last one remaining in her tribe when it was merged into the victorious Koror tribe; finished second in her surprise return the following season.
Odds of winning: 30-1
