Fantastic Four Vol 1 #054 - CGC 6.5

While the FF enjoy a playful baseball game with the Black Panther and his people in Wakanda, in the Hidden Land, the Inhumans try to convince Maximus to work on a device that will break down the barrier that keeps them trapped in their land. While back in Wakanda, Johnny wishes he could see Crystal again and so with a all terrain vehicle provided by the Black Panther, he and Wyatt Wingfoot travel to find a way to get past the barrier and get into the Hidden Land.

They come across an ancient temple where they rouse the last survivor of Avalon, Prester John, keeper of a powerful weapon known as the Evil Eye. Displaying it's power, he shows that it can fire destructive beams of force as well as create, when he seals Johnny and Wyatt in a force dome.

While in the Hidden Land, Maximus builds a device for Triton that allows him to survive outside of water, which irks Gorgon because Maximus should be building a device to free them, Black Bolt then tries to breach the barrier by using his destructive vocal chords.

While back at the temple of Prester John, Johnny takes the Evil Eye in hopes that it can free Crystal and the other Inhumans, however Prester was unable to push the safety switch on the device and it is now building up energy that will cause the device to explode. Rushing out to stop Johnny before it's too late, Wyatt uses a gun to shoot the Evil Eye out of Johnny's hand and knocking it a safe distance away before it explodes in a giant nuclear explosion. Even though his life was saved, Johnny takes this most recent failure very personally.
