I worry that, when I frequently repeat my refrain about how I don’t want any Darkseid in my Superman stories, I make it sound like I don’t want any of the contributions that Jack Kirby made in his Jimmy Olsen run to carry on into Superman stories. That’s not true at all!
I’m actually a huge fan of Jack Kirby’s work and I think any superhero franchise that has the opportunity to draw upon his imagination, it would be a mistake not to. It’s just that I consider the New Gods a separate franchise altogether, so I don’t want them to pollute one another. Similarly, I don’t care to see Guardian and the Newsboy Legion in Superman, because they ought to be allowed to stand on their own, not that I expect DC to ever be brave enough to try that (and I love those kids). But Kirby definitely put things into Jimmy’s book that I think belong in Superman:
To start, there’s the whole of the DNA Project (except, as I’ve said, for their Newsboy Legion connection). If Superman is, as I believe ought to be, an aspirational figure meant to show what the “Man of Tomorrow” should be like, then the DNA Project is a natural accompaniment to that idea. They are scientists in the employ of the government trying to create “men of tomorrow” with their science. There’s a whole race of “better” people called the Step-Ups who have essentially been created by the military industrial complex and who became hippies. And, of course, there are the less human “DNAliens” they create, such as Dubbilex, who is a fun character I absolutely think deserves to show up more often. (Naturally after some continuity revisions in the DC universe, the DNA Project would become known as Cadmus and would be responsible for cloning Superman to give us the 90s iteration of Superboy as well.)
Related to the DNA Project is Dabney Donovan. He’s one of many mad scientist villains you can have in Superman, but science is one of the key themes, so you can never have too many. Donovan’s particular brand of cloning and genetic modification gives him a niche to stand out against the rest. And his finest creation, the planet Transilvane, is simply a wonderful concept and the fact it has not yet been crossed over with Kandor in some story is a shame.
And it goes on. I’ve already mentioned that I think the books should keep Morgan Edge around, although I’d want him to use the post-Kirby characterization. Intergang has had iterations on television and (I think) in comics that had noting to do with Darkseid so that’s fine as the name for fancy sci-fi gangsters for Lois and Clark to deal with. Heck, even the Outsiders biker gang gives Metropolis something that resembles a common crime story element but with a more sci-fi take. I’m just saying, there’s plenty of things in Kirby’s short Jimmy run that are more than welcome in my idea of Superman books. Just not Darkseid. I can’t reiterate this enough. Let the New Gods have their villain.
