First Appearance: The Amazing Spider-Man Annual (Vol. 1) #19, August 1985
Powers: A baseline human with no superhuman powers, Alistaire Smythe is the son of Spencer Smythe, inventor of the robotic Spider-Slayers which were designed to capture and unmask Spider-Man. Spencer grew obsessed with killing Spider-Man, leading to his desertion of his family and eventual death. Grief-stricken and increasingly unstable, Alistaire blamed Spider-Man for his father's death. He eventually gained employement from the Kingpin, using his resources to invent a new generation of Spider-Slayers.
A self-taught genius in robotics and cybernetics, his knowledge enables him to re-create and upgrade his father's inventions and develop many of his own (including over a dozen variations of the Spider-Slayer. After suffering a paralysis, he invented a super-powered carapace that restored his mobility. While encased in his cybernetic carapace, he possessed superhuman strength (Class 10), speed, durability, as well as claws, talons, limb barbs, extendable "fangs" from his shoulders, and web shooting arms.
