While the restless Avengers quarrel amongst themselves, injured mercenary Erik Josten has been hiding out in the Amazon jungle since his employer Baron Zemo’s demise, fearing arrest for his past smuggling crimes. Digging in the rubble of Zemo’s headquarters, Josten unearths the laboratory where Zemo used ionic energy treatments to transform Simon Williams into the superhuman Wonder Man. Hoping to repeat the process on himself, Josten is approached by Zemo’s old ally the Enchantress, who uses Zemo’s machines to make Josten superhumanly powerful. Adopting a costumed identity supplied by Enchantress, a smitten Josten agrees to help her destroy the Avengers as Power Man. Enchantress later casts an illusion of a monster at Sutton Place, an illusion seen only by the Avengers, who cause property damage while battling the “monster.” Over the next two days, Enchantress and Power Man manipulate the Avengers into wrecking an empty subway train, then trick Captain America into attacking Power Man while the latter is foiling a robbery by two thieves disguised as guards. Josten defeats Cap thanks to Enchantress’ secret assistance. One by one, Hawkeye, Quicksilver and Scarlet Witch seek to avenge Cap’s defeat, confronting Power Man (again secretly aided by Enchantress), but their efforts end in defeat and arrest for trespassing. The City Council declares the Avengers a public menace and orders them to disband.
Observed by his Masters of Evil and Erik Josten, Zemo transforms Simon Williams into the superhuman Wonder Man (Av #9, ’64).
This story marks the Teen Brigade’s last known participation in an Avengers case. They inform the Avengers of the Sutton Place “monster,” apparently falling prey to the same illusion as the Avengers. This issue’s cover mistakenly depicts an “A” on Cap’s chest instead of a star. Hawkeye is the featured character in a full-page ad for Marvel’s T-shirts, including the Avengers T-shirt. The letters column promises a no-prize to the fan who invents the best civilian name for Hawkeye, but the character’s actual civilian name would not be revealed until Av #64, ’69. Letter writers in this issue include future Marvel writer Mike Friedrich, whose credits include the Huntress debut story (featuring Hawkeye’s future wife Bobbi Morse) from MSA Mag #1 reprinted in the Avengers: Hawkeye premiere hardcover.
