History
Alistair Smythe was the son of Spencer Smythe, the inventor of the Spider-Slayers. After Spencer died in a fight with Spider-Man, Alistair swore revenge ageist him and J. Jonah Jameson and became the super villain Spider-Slayer.
Alistair Smythe was the murderer of Marla Jameson, Jonah's wife. When he evaded his execution, he was hunted down and killed by Superior Spider-Man.
Smythe was resurrected by Jackal and he once again started scheming against Jameson. He kidnapped Jonah's girlfriend, Hann Riel, but she was rescued by Spider-Man and a spider-powered Jameson. Spider-Slayer later took part in a contest where the winner would receive powers similar to those of Spider-Man. He was the second opponent of Arachno-Man, who ended up defeating Smythe.[1]
