The Avengers #90

In "Judgment Day," the Avengers face a deadly Kree assassin sent to eliminate Captain Marvel, forcing the team into a desperate stand against the relentless Sentry #459. As tensions rise, Rick Jones begins to uncover the truth behind his mysterious connection to Mar-Vell, while a bizarre ad for a weight-gaining program hints at something far stranger beneath the surface. Written by Roy Thomas and brought to life with dynamic art by Sal Buscema—both on the interior and cover—this 1971 issue blends sci-fi intrigue with the team's signature heroism.
