Avengers #12

"This Hostage Earth!" – (20-page story) – Giant-Man believes something dangerous is happening beneath the earth but none of the other Avengers believe him, so he heads underground himself to investigate. Shortly after, he is captured by Mole Man. More damage occurs and the Avengers discover Giant-Man was correct, so they invade Mole Man's underground base.

Meanwhile, the Red Ghost approaches the Mole Man and they make an alliance. The Wasp manages to free Giant-Man and the team stops the Mole Man and Red Ghost's plans.
