Doctor Killebrew

Doctor Killebrew was the sadistic Weapon X scientist who oversaw brutal experiments on subjects in the Workshop, a hellish facility where he helped trigger the mutation that gave Deadpool his regenerative abilities — and his ravaged appearance.

From the very first issue of Deadpool's landmark 1994 solo series, Doctor Killebrew stepped onto the Marvel stage as a figure inextricably woven into one of the most irreverent corners of the modern age. Created by Mark Waid and Ian Churchill, this character has haunted the edges of Deadpool's world for three decades, surfacing across celebrated collections like the Epic Collection and Joe Kelly's definitive run — essential reading for any serious fan of the Merc with a Mouth. Sharing pages with Deadpool, Wade Wilson, Siryn, and Jack Hammer places Killebrew in genuinely compelling company, and a presence stretching from 1994 all the way to 2024 speaks to a staying power that few supporting players in Marvel's modern era can claim.
