Marita Covarrubias is a fictional character on the American science fiction television series The X-Files. She was initially introduced as an informant, leaking diplomatic information to FBI Special Agent Fox Mulder to aid his investigation of paranormal cases, dubbed X-Files. However, she was revealed to be an agent of the secretive Syndicate, although ultimately betraying that organization on several occasions. Introduced in the fourth season opener "Herrenvolk", the character remained a recurring presence until the series' finale, "The Truth".
The character of Marita Covarrubias was portrayed by Laurie Holden in all her appearances. She was introduced as a replacement for Steven Williams' character X, after the latter was killed by a Syndicate assassin. Holden's portrayal has received mixed criticism, being compared unfavorably to similar characters from the series.
Marita Covarrubias is introduced as an informant to Fox Mulder (David Duchovny) after the death of his former source, X (Steven Williams). X scrawls the letters "SRSG" in his own blood as he dies, leading Mulder to the Special Representative to the Secretary-General of the United Nations. Covarrubias uses her diplomatic connections to help Mulder infiltrate the Russian province of Krasnoyarsk, allowing him to reach the site of the Tunguska event. However, it is later seen that Covarrubias is working for The Smoking Man (William B. Davis) and the Syndicate.
During the fifth season, the Syndicate discovered that Covarrubias had betrayed them and was providing information to Mulder. As a result, Syndicate scientists infect her with black oil in order to test a vaccine they had been working to create. In the following season, Covarrubias is discovered by FBI agent Jeffrey Spender (Chris Owens) at a decontamination chamber. She begs him to help her escape the facility, addressing him by name as well as giving him information about the whereabouts of his mother, Cassandra. Alex Krycek (Nicholas Lea), a former Syndicate agent now acting alone, is also present at the facility. He declines to help the pair, and leaves Covarrubias for dead.
