I was an FBI agent, uh, that's Federal Bureau of Investigations, back in my home reality. I've spent the last few years of my life with my partner, Scully, whom I think you've also met, investigating unexplained phenomena. The weird, the things that don't line up with what people expect - I'm particularly interested in extraterrestrial life, something the government won't admit we've had contact with even though I'm pretty certain that's a highly classified lie. But people don't want it out, so they don't care much for my persistence.
Here, I'm just a fictional guy who you can watch make a persistent fool of himself for 9 seasons of The X-Files.
