Marvel Masterworks #4

In "The Avengers Meet...Sub-Mariner!", the Avengers grapple with the fallout of the Hulk’s departure, fearing the chaos he might unleash. When they encounter the rampaging Hulk, tensions explode into battle—until the Sub-Mariner intervenes, turning the tide as he brokers an uneasy alliance between the Hulk and himself against their common foes.

Captain America Joins...the Avengers! kicks off with a shocking discovery when Namor’s assault on an eskimo village unleashes a frozen figure from the melting ice—Captain America, revived after decades in suspended animation. The Avengers bring him back to New York, only to face a new threat: an alien who turns them to stone, demanding their help to repair his damaged spaceship. With Cap and Rick Jones leading the charge, the team must navigate alien technology and a surprise attack from Namor and his underwater forces—all while trying to restore their fallen allies.

In "Kang, the Conqueror!", the time-traveling warlord Kang arrives on Earth with a demand to rule the planet, forcing the Avengers into a desperate fight for survival. As Kang's power threatens to overwhelm them, it's the Wasp and the Teen Brigade who must hold the line long enough for the rest of the team to break free and stop the conquest.

In "The Avengers Break Up!", Immortus arrives with a bold offer: to join the Masters of Evil, wielding his mastery of Limbo to summon ancient forces and challenge the Avengers. With time itself bending to his will, he reshapes the battlefield—turning past legends into present threats—and forces the team to confront not just enemies from history, but the fractures within their own ranks.
