20 Essential Comic Issues You Must Read Before You Die
6. Fantastic Four #48
It's not hyperbole to say that if it weren't for Stan Lee and Jack Kirby, there wouldn't be a Marvel Universe.
Together, the pair created some of Marvel's most iconic characters and in Fantastic Four #48, they introduced one of the (literally) biggest threats their heroes had ever faced, Galactus.
The issue really ramps up the idea that Galactus is the ultimate threat, even showing the Skrulls (who were one of the F4's biggest enemies at the time) cowering in fear at his approach.
The story also introduced the Silver Surfer, who soon became one of the favourite characters of the duo.
