Fifty Years Ago!
This issue is from the true heyday of the Lee-Kirby collaboration on the Fantastic Four – other than the first 10 or so issues of the foundational Marvel universe series, I do not think any other string of comics has introduced such a lasting set of characters or stories. Starting with issues 44-47 (Inhumans), 48-50 (Silver Surfer and Galactus), 52-53 (Black Panther), 57-60 (Doomsday), 64-65 (Kree), 66-67 (Warlock)… not to mention the Negative Zone, and the fact that these 2 years are bookended by the Wedding of Reed and Sue and the birth of their son, Franklin.
After the destruction of Sentry 459 in the previous issue, the Kree Supreme Intelligence has become interested in the planet Earth. The Intelligence probes the minds of the Fantastic Four as they sleep, warning them that their guilt or innocence in the matter will be determined by his agent, Ronan the Accuser.
This issue marks the first appearance of the Kree race who originate from the planet Hala. Ronan the Accuser is depicted here with Caucasian skin, however all future depictions of Ronan shows him with blue skin typical of baseline Kree.
The FF find themselves trapped within the Aura of Negativity with Ronan. When the Thing tries to attack the Accuser he is instantly felled by a blast form Ronan’s Universal Weapon. He quickly downs Ben, Johnny and Reed.
