I loved that X-Files when I was a kid. The goofy monsters of the week episodes got me into the show but the loose overarching narrative got me hooked. I think as the show went on the big story got a little sloppy but the show does have a couple great episodes/seasons.
I don't really remember much about this guy except he was awesome. He was some sort of alien Terminator, big, unrelenting , and almost invincible. This guy has actually been in a lot of stuff but I always remember him as his X-Files role.
