Alex Krycek/Syndicate

===Syndicate Work===
In 1995, Krycek was assigned by the Cigarette Smoking Man to kill Mulder's father, William Mulder (a former Syndicate member). Complying with his orders from the CSM, Krycek waited in the bathroom of Bill Mulder's house and then shot him in the head, before fleeing through a window and evading capture. Following his success, he went to Mulder's apartment to kill him, but Mulder ambushed him, beat him and then held him at gunpoint, demanding to know whether he had killed his father. Before he could kill Krycek, or find out the answer, Scully arrived and shot Mulder to preserve his innocence, allowing Krycek to escape. 
Soon thereafter, Krycek and his partner, Luis Cardinal, were ordered to kill Dana Scully. After establishing that she would be at the house, they arrived early and prepared to kill her, once she returned home. However, her sister () arrived at Agent Scully's home, first. Consequently, she was accidentally shot by Luis Cardinal. Krycek – realizing the error, once he viewed the body – quickly fled the scene with Cardinal. 
Shortly thereafter, Krycek – along with Cardinal and another operative – assaulted in the stairwell of a hospital where Melissa Scully had been taken and was being treated. After fighting with Skinner, Krycek managed to steal the digital tape that Mulder had received. Before fleeing, Krycek maliciously continued to punch Skinner and left him bloodied and unconscious in the stairwell. Krycek was unaware, however, that the Syndicate was most displeased with his actions. In response to their reaction, the CSM arranged for Krycek to be killed by his partners, along with the tape.
When the three assassins stopped at a petrol station, Luis Cardinal and the third man left the vehicle, but Krycek noticed their suspicious behavior, and the flashing clock time and escaped from the car bomb that was intended to kill him. He then called the CSM from the airport and informed him, in no uncertain terms, that – if another attempt was made on his life – he would reveal all that he knew to the public. 
===Rogue Operative===
Krycek would remain underground, on the run from the Syndicate, until an unexpected reunion with Mulder. He waited in the office of a Hong Kong company that Jeraldine Kallenchuck worked for and, when Jeraldine entered the room with Mulder, Krycek pulled his gun. In the resulting struggle, Krycek threw Jeraldine into the hallway outside the office and shut the room's door, trapping Mulder and Jeraldine, as they were still handcuffed together. When men in suits arrived and murdered Jeraldine, Krycek escaped out of a window and ran off into the night.
At Hong Kong International Airport, Krycek was found and assaulted by Mulder, who took Krycek's gun and threatened him. Krycek revealed that he had hidden the tape in Washington, D.C., and vowed to give the tape to Mulder in exchange for his freedom. Mulder accepted Krycek's offer and sent Krycek into a washroom to clean himself up. While there, Krycek was assaulted by Joan Gauthier and was infected with the . He exited the bathroom and, remarking that he felt "like a new man", Krycek left with Mulder, who was unaware that his companion had been infected. 
Back in America, Krycek and Mulder were run off the road by another car. Krycek was taken by one of the men to be questioned but he instead irradiated the two men and fled, leaving Mulder at the scene with the key to the locker containing the digital tape. Krycek managed to reacquire the tape first, however, and exchanged it with the CSM for access to a crashed UFO that was hidden inside a silo in North Dakota. Upon coming into contact with this UFO, the black oil exited Krycek's body, leaving him alive but disoriented. However, the CSM prevented Krycek from leaving, effectively trapping him in Silo 1013. 
During a raid on a right-wing militia group in Queens, New York, Mulder captured Krycek after the rogue agent had killed the driver of the truck he was in and had tipped off the FBI with a series of receipts. He claimed that he had been rescued from the missile silo by the militia, and reasserted his patriotism as well as the notion that he had always intended to sabotage the group. He then gave Mulder and Scully information regarding other "bombs", which led them to the diplomatic pouch. Upon discovering the rock, Mulder took Krycek into hiding at Skinner's apartment. Skinner subsequently beat him and handcuffed him to a railing on his balcony. The following morning, a half-frozen Krycek awoke to find the courier ransacking Skinner's apartment. Krycek attempted to hide on the other side of the balcony's barrier but was heard by the intruder, who Krycek then dragged over the railings to his death. Krycek was then sneaked out of the building by Mulder, while Skinner was questioned by police.
Krycek subsequently accompanied Mulder again, first to Marita Covarrubias' apartment then to JFK Airport, where Mulder planned to abandon him in their car. When Krycek cursed Mulder in Russian, Mulder decided to bring him along with him. The pair arrived in Siberia, Russia and subsequently journeyed to Tunguska, using Krycek's knowledge of the Russian language, and went to sneak under a razor-wire perimeter. When Krycek asked what they were doing there, Mulder explained the Tunguska Incident to him, claiming that he was positive that the rock had emerged from the site. The pair were spotted and chased by guards on horseback, after seeing miners being whipped into work, and were then thrown into a cell. When Mulder confronted him, Krycek told Mulder that he was "gonna need me in here". Soon after, Krycek talked his way out of the cell. It turned out that the whole incident had been staged and that Krycek was on good terms with the camp's commanders. While Mulder and many other prisoners were tortuously tested with the black oil, Krycek dined with the gulag's head scientist. 
====Russian Syndicate====
Leaving Mulder to be worked to death in the gulag, Krycek took up a position of some prominence within the camp's hierarchy. While speaking with Glasses Man, Krycek was attacked by Mulder, who took him hostage and drove away in a truck. After traveling some distance, Krycek jumped clear of the truck, injuring his arm in the process. As he made his way through the forests in an attempt to return to the camp, he was ambushed by a large group of one-armed partisans. He told them that he was an American who had been accused of spying and that he had been a prisoner at the gulag. In response, they offered him protection. Waking that night, Krycek was grabbed by the partisans and had his left arm amputated by a hot blade as a precaution against the use of the black oil.
During the interrogation of the militia leader they had captured in Queens, Mulder and Scully learned that the group had not, in fact, rescued Krycek from the silo but that he had actually approached them, and that most of the ideas they used were his.
When Vassily Peskow returned from his mission in America, he was met in his St. Petersburg home by Krycek, who insisted that he was not there to once again bring Peskow out of retirement, but instead to congratulate him on the completion of a successful task. As he did so, he stirred his cup of tea, using his new prosthetic arm. 
:In all subsequent appearances, Krycek is seen wearing a prosthetic replacement, except Season 6 Episode 9 - S.R. 819 at approximately 44 minutes into the episode, Krycek is seen using his gloved left hand.
Krycek witnessed the Rebel Alien attack in Kazakhstan, along with a unit of Russian soldiers under his command, and remained hidden until daylight broke. At this point, they seized Dmitri, the young survivor, and moved to the flaming attack site, confronting Marita Covarrubias and her UN Peacekeeping Detachment. Krycek made it clear that the boy was theirs, and that the UN had no right being in their territory. After instructing Marita to tell the Syndicate that they could "kiss [his] American ass" and spitting at her feet, Krycek stormed off with his men.
Having brought Dmitri to the Tunguska gulag, Krycek had a technician perform the black oil experiment on Dmitri, much to the surprise of Glasses Man, and then absconded with him. Krycek boarded a Russian freighter at Vladivokstok, keeping his prisoner chained in the hold of the ship's bowels, occasionally giving him water. After the ship docked in New York, Krycek phoned the Syndicate, openly insulting the and making clear his scorn towards his former employers. He then offered to trade the boy – at this point, the only surviving witness of the rebel attack – in exchange for a vaccine for the black oil. Marita, who had overhead this conversation, found the ship and quickly seduced Krycek, drawing him away from Dmitri's cell. Krycek later returned to the ship's hold but found that the boy was missing, having been taken from the vessel by Marita. Before Krycek could react, the Well-Manicured Man appeared behind him, demanding to know the boy's location. After he didn't answer, the Well-Manicured Man had him handcuffed in the cell without food or water. 
After failing to negotiate with the Well-Manicured Man over his release and the acquisition of the vaccine, his captor deduced that Krycek had, in fact, come into possession of a cure. After the Well-Manicured Man told him that the ship would soon return to Russia with him on it, Krycek submitted and gave him the vaccine.
Soon after his release, Krycek ambushed Mulder in his apartment, beating him and throwing him to the floor at gunpoint. He told Mulder that a war was being waged by alien forces beyond their control and that the rebel aliens orchestrating the attacks were humanity's only hope of freedom. He then leaned over, kissed Mulder on the cheek, and surrendered his weapon before bidding him goodbye in Russian and marching out of the apartment. 
===Return to the Syndicate===
After striking a deal with the Well-Manicured Man, Krycek briefly conducted some work on behalf of the Syndicate. Krycek was assigned by them to bring the Cigarette Smoking Man out of retirement and to escort him back to them, so that the CSM could conduct an operation.
After locating his hide-out, Krycek and two other guns-for-hire parachuted into the mountains of Canada looking for the CSM, locating his cabin, but unknowingly tripping off one of his outdoor detection sensors. Knowing that he was about to be attacked, the CSM ambushed the trio and shot one of them, as he attempted to enter through the front door, before fleeing into the snowfields. The other two followed, and Krycek got the jump on him. After he removed his balaclava, revealing who he was, the CSM told him to "take his shot", clearly believing that he was there to kill him. However, Krycek said he was only there to bring him back.
Krycek handed his prisoner over to the Syndicate at a parking lot, where the CSM was given the task of finding and capturing Gibson Praise.
After successfully completing this task, the CSM handed Gibson over to the Well-Manicured Man in his car, which was being driven by Krycek. As CSM walked away, Krycek offered to shoot him, as he had a good angle, but WMM refused the option, saying that he still had use for him. 
Following Skinner's security checks into Senate Resolution 819, Krycek poisoned the Assistant Director with nanotechnology that was designed to simulate a heart attack under remote control. Using a long wig as a disguise, Krycek infiltrated FBI Headquarters and spotted Dr. Orgel attempting to speak with Skinner, scaring him off. By means unknown, he then poisoned Skinner before doing the same to Orgel. As the nanotechnology continued to eradicate Skinner's health, Krycek made moves to stop him from being killed by other elements, even going so far as to fatally knock down a would-be assassin with his car. He blackmailed Senator Matheson, killed Orgel as an example and went so far as to visit the hospital where Skinner was being kept. Using a voice synthesizer to phone and taunt the dying Skinner, Krycek was noticed by Mulder (although not recognized, thanks to the disguise), who gave chase in the parking lot. Eventually, Krycek was forced to ditch his car and flee on foot.
As the virus reached the point of actually killing Skinner, Krycek used the remote control to bring him back. After Skinner had recovered, Krycek visited him in his car, reminding him that he could set off the virus again, whenever he wanted. When Skinner asked what Krycek wanted, he was told that it would all be revealed "in good time." 
Krycek began to work more closely with the Syndicate, giving a briefing to its members regarding the incident in the train car and Cassandra Spender being left alive. He later made the point that, clearly, the rebels had left her alive in order to expose them. During this time, he seemed to serve mainly as the CSM's adjutant. He acted as a driver for for the assignment to kill the impostor within the group. After Jeffrey Spender was caught out attempting to use the alien needle, Krycek arrived and killed the rebel without hesitation. After showing sympathy for Spender's inexperience with extraterrestrials, Krycek revealed that Jeffrey's father had sanctioned the experiments on Cassandra and that they had every intention of having her killed. It was this conversation which sparked Jeffrey Spender to turn his back on his father and attempt to rescue his mother. 
Krycek stole Cassandra's medical files from the hospital, then reported her escape to the Syndicate, saying that the alien rebels wanted Cassandra kept alive. Regardless, the Syndicate decided to turn Cassandra over to the colonists and start prematurely, in order to save themselves. Krycek stayed behind in the Syndicate headquarters, however. While waiting, he found Spender arrive. Krycek told him that the Syndicate members were preparing to be given the hybrid genes, with the exception of Spender's father, who had gone to retrieve Cassandra.
As the Syndicate prepared to meet with the colonists, the CSM noticed that many were absent and queried Krycek's whereabouts. In actuality, Krycek was at Fort Marlen, following up on some suspicions regarding the exchange, and discovered the dead body of the scientist charged with handling the alien fetus. Krycek also discovered that the fetus had been stolen.
As he hurriedly went to leave, he was called to by Jeffrey Spender, who was stuck behind a security door with no way to escape. Krycek noticed that Marita Covarrubias, a ravaged shadow of her former self, was with him. After telling them that it was "all going to Hell" and that the rebels now had the upper hand, Krycek stormed away.
As a result of these deceptions, the Syndicate was tricked into a false meeting with the rebels and were slaughtered, along with Cassandra, with only the CSM and Diana Fowley managing to escape. 
Krycek went to Skinner's office to retrieve a tape of his conversation with Mulder and Scully concerning the alien artifact. He then brought the tape to Barnes in an introductory meeting. He found Mulder doubled over in pain on his way there, and stepped past him. Krycek then went to Africa to kill Steven Sandoz. 
Krycek went to Skinner's office again to obtain information from Skinner. He ran when Scully burst in and pulled the fire alarm to help his escape. He then went to 's apartment and killed him and took his laptop.
