Eugene Victor Tooms, often referred to simply as Tooms, is a villain from The X-Files who starred in two episodes - "Squeeze" and "Tooms" - making him one of the few antagonists outside the Conspiracy to make an appearance more than once. He is a cannibalistic serial killer who eats his victims' livers to extend his lifespan far beyond its natural limits.
A strange creature of unknown origins, Tooms can contort his body in ways no living human could achieve without injury or death. He also undergoes a hibernation process lasting 30 years in order to survive.
Tooms first known murder occurred in 1903 and would continue on 1933 and 1963 - this would have made Tooms at least 100 years of age by the time Agent Mulder and Scully tracked him down, though he physically resembled a fairly young man: strongly suggesting his hibernation also somehow regresses his aging process.
His inhuman nature was revealed more in "Tooms" when Mulder tracked him into a mall and into a nest resembling that of a wasp or spider located under an escalator. Tooms attacked Mulder for this trespass but was killed in the ensuing confrontation after Mulder activated the escalator, trapping Tooms in the mechanism.
- Hutchison had originally penned a screenplay for The X-Files which would have acted as a prequel/origin episode to Tooms, but this never got made. The name of the episode was Dark He Was and Golden-Eyed.
- Eugene Tooms is considered the most iconic "Monster of the Week" in all of X-Files lore, which is why he became a recurring character - being one of a select few villains who have haunted the agents more than once.
