The Avengers, Vol. 1 #270A (Marvel Comics 1986)

Marvel Comics’ The Avengers, Vol. 1 #270A opens the “Under Siege” saga with a definitive 1986 creative lineup featuring writer Roger Stern and artists John Buscema and Tom Palmer. The plot triggers immediately after widespread controversy forces the team to manage escalating tension, establishing Prince Namor’s official integration into the active roster. When super-villainess Moonstone leverages that public resentment to spark a coordinated protest outside Avengers Mansion, Captain Marvel and Captain America secure the perimeter while the Wasp pursues Moonstone into the underground drainage network.

The chase shifts into a confined sewer encounter where the heroes intercept officers responding to the disturbance, revealing that the criminal operative Crusher Creel has assumed law enforcement roles to exploit their presence. This issue plants the foundational threads for the Masters of Evil conspiracy while delivering direct narrative handoffs to Alpha Flight #36. The story also features brief appearances by the Absorbing Man, Titania, and Byrrah.

Buyers and archivists tracking mid-1980s Marvel continuity treat this 36-page original print as a primary reference point. It documents the structural shift toward ensemble politics and organized crime infiltration, executed through Buscema’s sequential breakdowns and Palmer’s precise inking techniques. Industry records confirm an original cover price of $0.75 for this specific printing.
