Slayback

Slayback is a dangerous mercenary who debuted as an antagonist in Deadpool's first solo miniseries, harboring a personal vendetta against Wade Wilson rooted in their shared brutal history within the Weapon X program's world of augmented killers-for-hire.

Slayback crashed onto the Marvel scene in 1993's Deadpool: The Circle Chase #1 — the landmark debut miniseries that launched Wade Wilson into his own solo spotlight — conjured by the dynamic creative duo of Fabian Nicieza and Joe Madureira at the height of the Copper Age's love affair with hard-edged, dangerous characters. Over a surprisingly durable thirty-year presence in the catalog, Slayback has kept some genuinely wild company, sharing pages with Deadpool himself, Weasel, and Jack Hammer in stories collected across Deadpool Classic and the Deadpool Epic Collection. With a key-issue appearance to their name and a place woven into the very foundation of Deadpool's solo mythology, Slayback is the kind of villain-adjacent figure that serious collectors and Deadpool devotees will absolutely want to track down.
