Fantastic Four #158

In "Invasion from the 5th (Count it, 5th!) Dimension," the Fantastic Four face their most bizarre threat yet as the Inhuman royal palace is overrun by the interdimensional conqueror Xemu. With Quicksilver racing to save Medusa and the rest of the team rushing to reclaim the Hidden Land, the line between rescue and ambush blurs. Written by Roy Thomas and brought to life by Rich Buckler’s dynamic art and Al Milgrom’s sharp cover inks, this 1975 issue delivers a high-stakes cosmic clash with a classic Marvel twist.
