When the Fantastic Four flew over Attilan, Gorgon caused their plane to crash. Medusa and the Inhumans approached the Fantastic Four. Medusa asked for the Fantastic Four's help in taking over the human race. However, when Mister Fantastic refused, Medusa had them placed in a dungeon. The Fantastic Four were able to escape but Medusa placed Thing under her mental control. However, H.E.R.B.I.E. was able to snap Thing out of it. Mister Fantastic then showed Medusa how terrible the outside world was compared to how Attilan was like a paradise. Medusa and the Inhumans then decided not to leave Attilan.
Sometime later Medusa reformed and became an ally to the Fantastic Four. Medusa then loaned her dog, Lockjaw, to the Fantastic Four to be their watch dog.
