Ok, "Per Degaton", it's like come on, that's obviously just Vandal Savage in a really bad wig.
Ha! Man that is exactly the kind of reaction both of those fascist rat bastards deserve. I would give anything to see the two of them lined up and just have someone in the crowd shout that while they're trying to project all this gravitas. Just to see the reaction of both of them when no one is buying their shit.
There are a couple of slight problems with that hypothesis though.
((Left) A headshot of Degaton taken from a colorized Justice Society newsreel, circa 1947. (Right) Vandal Savage on one of the few occasions he was brought up to an international court)
The obvious physical differences are, well, obvious. For one, Savage is nearly half a foot taller than Degaton (who is only 5'4" and infamous for wearing lifts in his boots). Vandal actually usually has LONGER hair than Degaton so the idea of him wearing a wig to pretend to be the other man is a bit illogical. And there's also the problem of the giant three slash scar across Savage's face that he evidently received on the same night he gained his immortality and therefore has never been healed by his biological powers.
They have a relatively similar build but to be honest being a supervillain tends toward pushing you into a certain kind of body. Especially if you plan to take punches from Wildcat and then get up having kept your head in the same position relative to your shoulders.
But here's the part that people often forget...Per Degaton is from THIS time period. Or, rather, he was born and living contemporaneously to the Justice Society and All Star Squadron. He's not some tyrant from the distant future as much as he would like to pretend he is. He was an assistant to a group called the Time Trust back during WWII who were working on the hail mary idea of traveling forward in time to find weapons that might give the Allied Powers an edge.
This idea was pretty swiftly abandoned after the first time it was tried. For the obvious reason that its a terrible idea that's going to cause a paradox so fast it'll make your head spin. Also that Degaton became ambitious and jealous of the work being done, killed basically everyone working on the project, stole a bunch of the technology and defected to the Axis where he spent the rest of the war being a pain in the ass. Ever since then him and his chronal duplicates have been bouncing around the timeline showing up who knows where for who knows why and usually getting his teeth knocked out by spandex clad do gooders no matter WHERE he goes. But the point stands that we still have the man's birth certificate.
Vandal Savage, while he is not NEARLY as many historical figures as he CLAIMS he was (birth records back then were bad but they were not THAT bad especially when it came to royalty) he is, famously, a Neanderthal that came in contact with a radioactive meteorite and was granted immortality. He doesn't have a birth certificate because he was born before the invention of writing let alone paper records.
The two men also don't really get along in the "two massive egos that could generate gravity" kind of way though they 'served' on the original Injustice Society together. Savage's dalliances with time travel have generally just been another villainous scheme rather than his main gimmick a la Degaton.
Really Degaton is the more classic kind of clean shaver goosestepping loser whereas Savage looks like he's going to tell you to eat raw beef liver and expose your anus to direct sunlight INBETWEEN ranting about "traditional values"
