Mulder/Krycek was one of the first big slash pairings on the net. They were enemies who loved to hate each other and Mulder especially liked to get really physical when expressing his hatred. At the same time they were sometimes reluctant allies.
Betrayal, redemption, trust issues, and Mulder in denial about his attraction to Krycek were common themes in fanfic.
The motto of the Mulder/Krycek Romantics Association was: For those who know real UST when they see it! It was a comment on the often talked about Mulder/Scully UST and referred in this context to all the angry tension between Mulder and Krycek that was perceived as sexual. That fan interpretation of the character dynamic got a bit of fanservice later in canon when Krycek kissed Mulder on the cheek in the fifth season episode The Red and the Black.
When the X-Files hysteria started, I avoided getting drawn into it by the simple means of not even watching a single episode. What happened then is what happens every time you say "never" to a new fandom: you fall for it, hard. I discovered Mulder/Krycek slash via a due South author's other work, begged tapes from mareen, read whatever I could get my hands on, and was captivated by the complicated relationship between Fox Mulder and Alex Krycek. From partners to mortal enemies, to reluctant allies, to... lovers? At least that's what fandom said, and I agreed. No matter how little I care for Chris Carter's botching of the mytharc in the later seasons, I'll always be grateful to him for that kiss in "The Red and the Black", and for the tremendous potential inherent in Krycek's character. Fandom was certainly an experience although I avoided the extremes of the spectrum - the Krycek-defenders who excused or denied his crimes, and the people who saw him as a sociopath without a conscience. I prefer the middle ground and am wholly comfortable in denying the events of "Existence". Krycek, dead? I must have misheard.
