In anticipation of The X-Files’ 25th anniversary next month, Mattel partnered with 20th Century Fox Consumer Products to develop The X-Files Barbie collection.

The collection included characters from the sci-fi series, including Special Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson). The dolls are available starting today on amazon.com and barbie.com.

Each doll wears the characters’ signature looks from the ‘90s—dark suits, an FBI identification badge, and a badge. Both come with a doll stand and certificate of authenticity.

On September 10, the series’ 25th anniversary, shop.fox.com will host “The Truth is Out There Trivia Contest.” Participants who answer the most questions correctly before the contest closes on September 17 will be entered to receive an X-Files 25th Anniversary Prize Pack, which includes the Barbie dolls.

Starting today, fans can submit their own X-Files trivia questions at shop.fox.com for the chance to receive an exclusive X-Files prize pack and have their question included in the trivia contest.
