Long-running reality series "Survivor" returns for its 32nd season with "Kaoh Rong – Brains vs. Brawn vs. Beauty." 18 new castaways will try to outwit, outplay and outlast one another to become the Sole Survivor.

This season, the 18 castaways will be separated into three tribes – Brains, Brawn and Beauty, with 6 members each.

"The division of brains, brawn and beauty once again is really interesting. Even from the first three days, you see very clear differences within each tribe. And loyalty is a theme this season, but, then again, when isn't it?" host Jeff Probst told Entertainment Weekly.

The 18 contestants of "Survivor: Kaoh Rong – Brains vs. Brawn vs. Beauty" range from 19-year-old student Julia Sokolowski to 72-year-old former FBI agent Joseph Del Campo. Two famous faces will also be joining the season – Scot Pollard, a former NBA champion and Caleb Reynolds, army veteran and former "Big Brother" contestant.

The Brains tribe will be called Chan Loh and consists of the following cast members – ER doctor Peter Baggenstos, ice cream entrepreneur Neal Gottlieb, chemist Debbie Wanner, social media marketer Aubry Braco, former FBI agent Joseph Del Campo and quantitative strategist Elisabeth Markham.

The Brawn tribe "To Tang" consists of body builder Cydney Gilon, postal worker Darnell Hamilton, real estate agent Alecia Holden, bounty hunter Kyle Jason, contractor Jennifer Lanzetti and Pollard.

Finally, the Beauty tribe "Gondol" will be made up of bartender Michele Fitzgerald, pro poker player Anna Khait, personal trainer Nick Maiorano, gardener Tai Trang, Sokolowski and Reynolds.

In last season's "Survivor: Cambodia – Second Chance," Immunity Idols were hidden during challenges and the all-star cast had the added challenge of obtaining it without anybody else looking. Now, in the upcoming season, "Survivor" will once again introduce a new twist to the hidden Immunity Idol.

"The big idol twist this season is that an idol has two separate powers. If you find an idol, it has the regular powers of a normal idol. But when you put together with another idol – two can actually fit together – they can be used as one super idol that can be played after the votes are read," Probst revealed.

Be sureto the catch the 90-minute season premiere episode titled "I'm a Mental Giant."

"Survivor: Kaoh Rong – Brains vs. Brawn vs. Beauty" premieres on Feb. 17, Wednesday at 8 p.m. ET on CBS.
