Syndicate Quicky-Bios

CSM:
One of the most seen Syndicate members, and now one of the few still left alive. He is Samantha, Jeffery Spender, and possibly Mulder's father, and almost died once of lung cancer but was miracuously cured. He is currently working with Diana Fowley.

Alex Krycek:
Around 30 years of age, this man isn't to be trusted. He's been known to go with the highest bidder instead of staying loyal to one group of people. He was once infected with the black oil and locked in a missle sihlo in North Dakota. He had his left arm chopped off in Russia so he wouldn't be tested on and he's very close to Marita Covarrubias.

Well Manicured Man:
This man is the least evil of the Syndicate members, really caring about his family and he once saved Scully's life. He saved Scully's life again (In the X-Files Movie), giving Mulder the coordinates of where she was being held and a vaccine that would save her life. He then commited suicide (blew up his own car).

Deep Throat:
Deep Throat is Mulder's first secret informat who met him for the first time in the second episode of the series. Throughout the whole first season, Deep Throat helped Mulder here and there, whether to help "uncover the truth" or to stop Mulder from finding it we're not sure. Then, in The Erlenmeyer Flask, he was shot and lay dying in Scully's arms.

Mr. X:
Mr. X is the second of Mulder's informats, who, like Deep Throat, gives Mulder the information he needs. But unlike Deep Throat, X seems to try to stop Mulder from doing certain cases and often tells Mulder that he isn't going to die at Mudler's expense like Deep Throat did. At one point, we find out that X works for CSM, but may have a different agenda. Then, in the episode Talitha Cumi, X takes pictures of CSM and Mulder's mother (Tina Mulder) talking. CSM finds out about these pictures and in Herrenvolk, orders someone to shoot X. So, as most of the people Mulder comes into contact with, X dies, writing SRSG at the door of Mulder's apartment. This leads Mulder to seek help from Marita Covarrubias.

Vassily Peskow

Victor Klemper:
This man used to be a German war criminal (as did many of the other Syndicate members) and was part of Operation Paper clip, a top secret project between the U.S. and the Germans back in the 1950's. He then retired from the Syndicate and took up gardening. After giving Mulder a clue as to where a secret government place was containing secret files, he died among his flowers (presumable killed by another of his "friends").

Crew Cut Man

Red Haired Man

Quiet Willy:
Name says it all.

Section Chief Scott Blevins:
This is the man that assigns Scully to work with Mulder in the first place. Deep Throat works above him and is once told "Keep your friends close, but keep your enemies closer."

Section Chief Joseph McGrath

William Mulder:
He's supposedly Mulder's dad, but we're led to believe that CSM may be Mulder's father so I'm not sure. William Mulder was killed by Alex Krycek in the episode Anasasi, right after telling Fox that the government has many dark secrets. We barely ever see him show any sign of love or affection to Fox and we find out that he's the person who let the men/aliens take Samantha.

Surgeons:
Other characters that help out the Syndicate members from time to time are those weird Japanese surgeons. They specialize in cutting up/testing people such as Cassandra Spender who have been injected with the black oil vaccination and working with aliens in strange anti-contamination suits.
