30 Day X-Files Challenge Day 20: Favorite One-Off Character

This challenge was produced with the help of Sir Simon Milligan for the prompts!

One of The X-Files’ trademarks was its Monster of the Week (MOTW) episodes.  These episodes provided dozens of opportunities to introduce characters who’d appear only once throughout the series, but leave a lasting impression.  Whether they were portrayed by well-known actors or up-and-coming talents, there are a lot to choose from when it comes to picking a favorite.

Prompt: Who’s your favorite one-off X-Files character?

The main criterion here is to pick a character who only appeared in one episode.  It can be a tough call, so don’t feel like you have to limit yourself to just one choice!
