The Amazing Spider-Man #12

In "Another Return of the Sinister Six!", Sandman assembles a new lineup of villains to take on both Spider-Man and Doctor Octopus, reigniting an old rivalry with fresh stakes. With Spider-Man tangled in a confrontation with Arthur Stacy, the mystery of his grudge against Senator Ward is cut short when the newly formed Sinister Six strikes—and Venom’s shocking inclusion adds a dangerous new layer to the chaos. Written by Howard Mackie and brought to life by John Byrne’s dynamic art, this 1999 issue features Byrne on both pencils and inks for the cover, capturing the intensity of a battle where old enemies and unexpected allies collide.
