The Avengers, Vol. 1 #321A (Marvel Comics 1990)

The Avengers Vol. 1 #321A, published as a Direct Edition by Marvel Comics in 1990, delivers a decisive pivot in the "Missing Links" storyline through a high-stakes multinational intervention. This thirty-six-page issue guest-stars Alpha Flight and Stingray, focusing on a Russian terrorist takeover of the submarine Waterwind near Newfoundland. The plot resolves around a coordinated strike against an impending nuclear detonation, uniting civilian authorities and super-heroes across political lines. The People's Protectorate assumes operational command while deploying three distinct groups to secure the vessel.

Fabian Nicieza writes the main narrative, with Rik Levins providing pencils and Chris Ivy handling inks. Guarding the initiative is Commander Hudson known as Guardian, who directs a tactical breach of the dry-docked submarine by Captain America, Red Guardian, Box, Puck, the Vision, and Vostok. The infiltration squad navigates through resistance fighters with efficiency, yet faces a sudden disruption in the missile control room where the team uncovers a critical development that alters their mission parameters. The story also includes cameo appearances by Tyrak, Okra, and Merrano.

• Avengers Lineup: Captain America, Quasar, Sersi, and the Vision.
