21 Challengers of the Unknown
During Kirby's less well-remembered stint with DC Comics in the 1950s, he launched the adventuring teams the Challengers of the Unknown, four men who each survived a plane crash and decided that since they were now living on "borrowed time," they should seek out more adventure. This was a huge influence on the Fantastic Four.
22 Circus of Crime
Kirby didn't plumb the depths of his Golden Age work on Captain America that much, but one of the surprising places where he did was with the Circus of Crime, who appeared in an early Captain America Comics issue before being revamped for the Silver Age.
The big bad wolf, the evil center of Kirby's Fourth World Saga, Darkseid is one of the most critically acclaimed bad guys in comic book history.
Darkseid's sadistic underling, Desaad, is particularly interesting because Darkseid has killed him and brought him back a number of times. Can a soul really handle that many changes.
25 Doctor Doom
One of the greatest villains of all-time, Doctor Doom has tormented the Fantastic Four many times over the years in an attempt to get the best of Reed Richards, the one man that Doom might be willing to admit is someone that he admires as an adversary.
26 Doctor Druid
Originally created before any of Marvel's major 1960s heroes, Doctor Druid was originally Doctor Droom and he actually turned Asian when he gained his powers. This was edited away when his first appearance was reprinted, with Droom now becoming Druid.
27 Doctor Faustus
A longstanding Captain America villain, Doctor Faustus was basically like if Sigmund Freud became a super villain.
28 Dragon Man
Dragon Man is another in a long line of artificial characters who ended up turning against their creators to become, if not heroes, then at least not valent
Introduced as part of Cadmus in his Jimmy Olsen comic book stories, Kirby's Dubbilex is a perfect example of how you cannot judge a book by its cover, as the bizarre looking clone is one of the nicest telepathic people you would ever meet
30 Ego the Living Planet
Showing off the pure magnificant scale that Kirby and Lee were working on, Ego The Living Planet is one of the great cosmic additions to the Marvel Universe. Imagine! An actual living PLANET!
31 Enchantress and Executioner
The beautiful Enchantress and her stoic enforcer, the Executioner (who was in love with her while she just treated him like garbage), were steadfast villains of both Thor and the Avengers as part of the Masters of Evil.
When he returned to Marvel Comics, Kirby tried to do a version of the New Gods with the Eternals, an evolutionary offshoot of the human race that was never meant to be part of Marvel continuity. It was only when Kirby left Marvel that later writers worked the Eternals officially into Marvel continuity.
33 Etrigan the Demon
One of the earliest creations Kirby did for DC when he returned to them in the 1970s was Etrigan the Demon, a demon from the days of King Arthur, who was trapped in his human form, Jason Blood, for hundreds of years before finally becoming free in modern times.
34 Fantastic Four
The superhero team who launched the Marvel age of comics in the 1960s, the Fantastic Four was greatly influenced by Kirby's Challengers of the Unknown, and you can't help but notice a good deal of Kirby's own personality went into the making of the Thing.
35 Female Furies
Subtlety was not something that you would ever find in a New Gods comic book, and that was certainly the case with the female furies, the Apocalyptic strike force that big Barda was once a member of.
36 Fighting American
When Atlas Comics (soon to become Marvel Comics) brought their creation Captain America back to comics in the early 1950s, Joe Simon and Jack Kirby were upset enough that they decided to launch their own version of Captain America named the Fighting American. While initially they were telling stories that were just as anti-communist as the Atlas version of Captain America, they quickly turned it into a superhero satire series
37 Fin Fang Foom
One of the interesting things with Marvel in the 1960s was when they would look back upon their successful days of doing Monster comics and bring some of the more popular monsters into the superhero stories. Perhaps the most popular one of the early monsters was Lee and Kirby's Fin Fang Foom, who then became a popular villain of Marvel superheroes for years.
38 Forbush Man
Kirby could do humor as well, especially when he helped design Marvel's amusing mascot, Forbush Man.
39 Forever People
These New Gods were Kirby's attempt at doing a positive depiction of the then popular hippie movement in the United States.
With the 50th issue of their Landmark Fantastic Four series coming up, Lee and Kirby decided to go big-time with the villain for the 50th issue, deciding to introduce, in effect, a god for the Fantastic Four to fight. The god in this case was the planet eating Galactus.
