One of the great gems from Kirby in his latter days of the Silver Age at Marvel was his delightful story in Not Brand Echh #1 spoofing his own epic tale of how Doctor Doom seduced the Silver Surfer and for a time stole the "Power Cosmic". It's a great yarn and the send up in NBE is pretty good too.
Kirby also did the cover for that debut issue of Not Brand Echh, with his cast of characters from the Fab 4 mostly present along with the awesome threat of the mysterious Forbush Man, the most dangerous figure in the Marvel mythos since the arrival of Galactus himself. Forbush Man was possibly more damaging.
