In an indirect cross-over, Yellowjacket received a call in Avengers #189 that his wife, the Wasp, was stranded in Las Vegas following her adventure in Defenders #76-77.
Borrowing an Avengers Quinjet, Yellowjacket arrived to find that Wasp, Hellcat, and Valkyrie had stumbled into a plot orchestrated by the Mutant Force and a band of warrior women obeying the commands of Mandrill. The predicament drew attention to a seldom-mentioned curse that limited Valkyrie's fighting skills against other women at this point in her crimefighting career.
The villains soon captured Yellowjacket (#78) and then trapped Wasp in a jar like an insect. Fingers covering the air holes in the lid prevented Wasp from succumbing to Mandrill's mutant pheromones, but Hellcat and Valkyrie fell under his power to bend the will of most women (#79).
Wasp managed to escape, and Nighthawk arrived late on the scene to rescue the other heroes (#80).
