Spencer struck a deal with Norman Osborn of Oscorp Industries. Osborn would construct a hoverchair for Alistair to use if Spencer would succeed in destroying Spider-Man, with Norman being blackmailed by the Kingpin into doing so. Spencer constructed a "Spider-Slayer" robot, the "Black Widow", to hunt Spider-Man. However, the Widow unintentionally kidnapped Flash Thompson, who was impersonating Spider-Man at the time. Spider-Man arrived to save Thompson, which led to a large-scale battle at Oscorp which resulted in a fire. Spencer was determined to finish off Spider-Man and insisted on staying in Oscorp while Norman got Alistair to safety. However, Spencer failed and seemingly perished when Oscorp exploded.
Shortly after Alistair lost his father, the Kingpin approached him. While reluctant at first, Alistair accepted the crime lord's offer of providing him with a laboratory, which he would use to construct more Spider-Slayer robots to destroy the man he saw responsible for the loss of his father: Spider-Man. Alistair built several robots in his father's honor, although they all failed to eliminate the wall-crawler. Alistair's failure meant that he would have to continue to work for the Kingpin until he succeeded.
The Kingpin eventually became tired of Alistair's bungling, after Alistair's plan to frame Peter Parker resulted in the arrest and imprisonment of Fisk's son Richard, as well as Spider-Man discovering Fisk's double life as the Kingpin. The Kingpin blamed the incident on Smythe's "incompetence" and had Herbert Landon transform Alistair into a Spider-Slayer robot himself, programmed to destroy Spider-Man. However, Alistair escaped the programming, having discovered that his father had been kept in cryogenic suspension by the Kingpin throughout their partnership.
Having defected from the Kingpin once and for all, Alistair began to work for several more villains, particularly Silvermane, who promised to fund research to revive his father.
