#8 Doctor Spectrum
Out of order but related to the previous post, we have Squadron Sinister/Squadron Supreme member Dr. Spectrum. He’s a Green Lantern knockoff, and there are a bunch of different versions of the character (some good and some evil), but all of them have a Power Prism that lets them control colored plasma energy.
The original Squadron Sinister version of the character was Dr. Kinji Obatu, who was introduced as the Ugandan finance minister. (Until the Grandmaster created the Squadron Sinister and gave him a Power Prism.) As he was a finance minister, it’s unlikely, but not impossible, that his doctorate was in medicine.
After Obatu’s death, the Power Prism was found by a sanitation worker, who brought it to televangelist William “Billy” Roberts. Roberts, clearly a pastiche of Billy Graham and Oral Roberts, was the sort of ‘70s evangelical fundamentalist that you can totally see becoming a supervillain given half a chance. While he likely had a wall of honorary degrees from non-accredited Christian colleges, Roberts was not a doctor.
Fragments of a broken Power Prism possessed Janet Van Dyne (the Wasp) and briefly turned her into Dr. Spectrum. Though the movies took her in a different direction, comic Janet was originally a fashion designer and never had an advanced degree.
The Power Prism bounced around to several other characters over the years. Martha Gomes was a factory worker from Des Moines, Iowa who was briefly Dr. Spectrum in service of the Purple Man.
She eventually passed it on to Henry Pym’s former lab assistant, Alice Nugent—who was revealed later to secretly by Dr. Alice Nugent, founder and owner of Nugent Technologies.
The first run of the Squadron Supreme gives the heroic character’s backstory on Earth-712 that Joseph Ledger was a former astronaut who saved a stranded Skrull and was given the Power Prism. (A copy of this character was later created by Mephisto; that one was a colonel in the United States Air Force.)
The rebooted/alternate universe version of Joseph Ledger in Supreme Power was a US soldier who accidentally bonded with the Prism. It’s unclear if he’s even an officer; his career backstory is sparse.
And finally, Nenet, the Doctor Spectrum of Earth-4290001, was an oceanographer. That’s a job you can do with a bachelors or masters and her civilian identity is never given an honorific.
Verdict: Of nine Dr. Spectrums, only the first and one other were actually doctors.
