The Avengers #143

The cover of this January 1976 issue declares "The Avengers Break Loose!" in bold letters, and Gil Kane's pencils (inked by Frank Giacoia and Mike Esposito) deliver on that promise with tremendous energy — Beast leaping forward in a furious blue blur, Captain America and Iron Man surging beneath him, the Scarlet Witch breaking free from a tangle of yellow-green coils, and Vision phasing in from the upper corner, all united by the rallying cry "Avengers Assemble!" Inside, Steve Englehart and George Pérez bring the story "Right between the Eons!" to life, with the cover teasing "At Last!! The Final Battle against the Power of Kang!" — promising a showdown that's been building to a head. A terrific snapshot of Earth's Mightiest Heroes at full tilt, with a creative team firing on all cylinders.
