The X-Files: 10 Best Characters Only In One Episode

10. Dr. Bambi Berenbaum (War Of The Coprophages)

When a small town in the northeastern US suddenly becomes infested by killer cockroaches, Mulder and Scully disagree on exactly what the bugs are doing to the ever panicking civilians. Their disagreement leads Mulder into a seemingly abandoned house under the control of the US Agriculture Department.

Inside the house, Mulder is swarmed by an honestly terrifying amount of cockroaches and thankfully is saved by the very attractive but also very annoyed Dr. Berenbaum in her shorts and a loose T-shirt.

Dr. Berenbaum, who Mulder gives the pet name "Bambi" due to her parents being naturalists, has a very comedic look at explaining UFOs. She simply sees them as swarms of cockroaches that encounter pockets of electricity causing them to glow.

Mulder's infatuation with the doctor that compliments the size of roach genitals makes Scully very jealous. But hilariously Scully's jealously ends up being for naught when the sexy Dr. Bambi finds another scientist who wins her over with his intelligence instead of his physical appearance.

This makes Scully very satisfied as she comments on how the pair may have some of the smartest children ever, and leaves Mulder with a simple line "Brains are the new sexy."
