There's a little super-hero in all of us, I reckon.
Volton:
Volton comes on strong. I mean, look at the guy: crotch-forward, power device on a chain welded around his waist, moisturized, in his lane. The very second he figured out how to have super-powers he was in his element.
And because Volton (aka Guy Newton) HATES CRIME and HATES CRIMINALS he heads on down to the local police station in his only-the-most-confident-heroes-wear-them sweater vest and beats up cops until they let him be a semi-official vigilante. And he is much more qualified than the pack of ding dongs the Commissioner here has working for him - do any of them have electrically powered super strength or an electrical forcefield or the ability to suck the electricity out of a person to stun them? They do not.
Volton does such a good job beating up crooks that not only does the Commissioner come around on him but lets Volton date his daughter. This is the workaround for those fathers who ostentatiously display a shotgun when the new beau comes around, fellows: vigilante justice. (Cyclone Comics 001, 1940)
Volton is our second encounter with a future member of Marvel's team of public domain super-heroes-turned-Nazis the Battle-Axis, and it's hard to say if Roy Thomas did him the most dirty or the least. His stated reasons for the heel turn are certainly the flimsiest of all the Battle-Axis members but just like his revised origin of having been struck by lightning they aren't actually true, as this version of Volton is a prototype of the same kind of android as the Human Torch, taken along when Dr Nemesis Death split from Phineas Horton after helping him create android life but before turning to fascism.
All this is interesting in a universe-building kind of way (the Human Torch has a little brother who hasn't showed up in decades! What's up with that?) but a bit of a missed opportunity in that the original version of Volton is more than a bit fascist. Why bother making the Human Meteor go Nazi for Ireland when you could have him be the android and simply let Volton follow his heart?
the Red Knight:
What can I say: I like super-hero-adjacent characters and stories of knightly adventure are full of those. The Red Knight, for example, is Sir Miles of Lorraine and he has special red chain mail! and that's about it. Even worse, his adventures are set during the First Crusade, so there are likely to be fewer dragons and evil warlocks and more historic war crimes heinous enough to still come up in international relations. Lucky for me, the Red Knight series only had two installments and the second one (the one more likely to have war crimes in it) is missing! As it stands, the Red Knight spends most of his energy dealing with his evil uncle rather than in slaughtering all and sundry. (Cyclone Comics 001, 1940)
Robo of the Little People:
Like Electro before him, Robo here is actually a super-powered robot piloted remotely by a scientist (in this case a guy named Vedik). The gimmick in Robo's case is that he was constructed as a giant robot by the inhabitants of an isolated Antarctic valley but once he started to explore the outside world for them it quickly became clear that his creators were in fact very small and Robo was the size of a regular human.
Robo probably would have transitioned into regular super-heroing at some point but since he only has a handful of appearances most of his adventures are concerned with day-to-day survival in our wacky world. (Cyclone Comics 002, 1940)
The Eye:
The Eye is just that: a huge, disembodied eye with associated lid, lashes, etc, that appears with or without a halo of flame to serve the cause of justice throughout the world. It is, without a doubt, an outlier in the group of beings that can be labelled "super-hero".
About the only thing that we know about the Eye is that it is a well-known figure world-wide. It's been operating for long enough that legends of its deed are present in a number of different cultures and whispered of by the criminal fraternity. Other than that: nothing. The Eye sees injustice and metes out justice and that's all.
Actually, there is one other thing we can infer about the Eye: either its power levels or its willingness to act directly varies over time. Sometimes, as above, it takes the shortest route to justice, employing heat rays and knocking planes out of the air willy nilly. Other times (and particularly by its last few appearances), the Eye contents itself with passing off information to human agents such as lawyer Jack Barrister. Is the Eye periodically short on power? Is it bored of the lack of challenge inherent in eye-beam based justice?
The Eye's eye also flips from left to right sometimes. This is actually quite eerie! (Keen Detective Funnies v2 012, 1939)
