Fans of The X-Files love The Lone Gunmen, and the three of them will return in January’s The X-Files Revival!
Following their short-lived spin-off series, The Lone Gunmen were killed off in The X-Files. Their death episode served as both an episode of the main series as well as the series finale for The Lone Gunmen. They did appear, naturally, in the series finale of The X-Files and a later comic established that they faked their deaths.
Dean Haglund, one of the Lone Gunmen, confirmed on Twitter that the trio will appear in the upcoming six episode revival of The X-Files:
yep, it's true. https://t.co/w718E0y6i8

Will their appearance make the comic canon, meaning they’re alive, or will they be in a dream of hallucination?
