Debbie Wanner is one of the returning castaways to get another chance at winning $1 million on Survivor: Game Changers this spring.

Debbie, a 51-year-old from Reading, PA, worked as a chemist when she first appeared on Survivor.

This all-stars season, the franchise's 34th edition, will premiere with a special two-hour episode on Wednesday, March 8 at 8PM ET/PT on CBS. The show's debut marks Survivor's milestone 500th episode.

Survivor: Game Changers, filmed in the Mamanuca Islands in Fiji in June and July 2016, will feature 20 castaways who are being billed as having made some of the biggest moves in the history of the game divided into two tribes, Mana and Nuku, that are each comprised of 10 veteran players.

Debbie will be competing on the "Nuku" Tribe with Andrea Boehlke, Brad Culpepper, Sierra Dawn Thomas, Cirie Fields, Sarah Lacina, Oscar "Ozzy" Lusth, Zeke Smith, James "J.T." Thomas, and Tai Trang.

Below is a list of five facts Reality TV World has compiled about Debbie Wanner:

- Debbie previously played on Season 32, Survivor: Kaoh Rong -- Brains vs. Brawn vs. Beauty, in Spring 2016 and finished in ninth place.

Debbie, a Brains tribe member, was blindsided and voted out of her tribe on Night 24 at the game's eighth Tribal Council session once the girls decided to betray her.

- Debbie told Reality TV World after Kaoh Rong that her tribe didn't have the "fortitude, guts or courage" to vote out Scot Pollard instead.

When Scot and Kyle Jason poured water on the tribe's fire, Debbie said the women "cowered in the corner and sucked their thumbs" when she decided to declare "psychological warfare" and steal the guys' clothing. Debbie memorably called the two men "bullies" that season.

- She was the first person in her family to graduate college and claims to have torture training as well as military training in summer and winter survival.

- Debbie, known for her eccentricities and unusual history of wild occupations, prepared herself to play a grittier game on Game Changers. She said all sense of nurturing or talking someone out of quitting was gone, and she had no intention of trusting her former tribemate Aubry Bracco.
