Launched under the Marvel Knights imprint in 2004, Marvel Knights 4 was a Fantastic Four series that was written with much less of an emphasis on the science fiction aspects of the characters and more grounded in the drama and family life of the four. Written entirely by Roberto Aguirre-Sacasa, the series featured art by Steve McNiven, Jim Muniz, Valentine DeLandro, Mizuki Sakakibara, & Clay Mann.
