Two shorts and two longs.
Bajah:
Minor Golden Age Marvel magician Dakor has to travel all the way to the fictional Indian kingdom of Nordu to rescue his friend's daughter from one of those cults where they worship a random blonde white lady (one of the more embarrassing stupid pulp fiction concepts to make the jump to comics, in my opinion). All that is to set up the fact that the devil figure in this cult is the oft-invoked, never-seen Bajah, as seen above. (Mystic Comics v1 003, 1940)
the Goat-Men:
The Goat-Men are a class of demon who serve Lucifer, and specifically the Lucifer seen in the last Demonic round-up, because this particular one is summoned by the Voodoo Man, just as his boss had been.
The Goat-Men are fire demons, who can both breathe fire and create a ring of fire by walking in a circle around something or someone. Plus: the ring of fire gives you malaria. This is a pretty good collection of demonic powers, and while the part of me that writes about super-villains wants to say that they are insufficiently related to goats for my liking, anyone familiar with Medieval demonology will tell you that having a suite of abilities that are completely disconnected from both the demon's physical appearance and one another is very accurate.
Just like his boss, the Goat-Man proves to be intensely vulnerable to the sight of a cross, to the point of explosion. Just why hero Bob Warren had to light the cross he used on fire is perhaps best left unexplored. (Weird Comics 007, 1940)
Kor Deno:
Kor Deno, a demon of some might, has been haunting the same family in... the rural United States? I'm pretty sure that's where Warlock the Wizard hangs out... for generations. Any female member of the family who marries will be widowed by the demon soon after and for the latest and perhaps last scion, Valya, the curse has grown in scope to the point that Kor Deno has carried off all of her friends and family.
Warlock the Wizard is if nothing else a romantic, and so he challenges Kor Deno's might in order that Valya might wed or at least kiss her love, Jim. He scores an early victory by using the the Golden Hand of Abraxas to crush the demon's cool shadow form, but finds himself to have been overconfident, as both Jim and Valya are carried off to Kor Deno's Black Kingdom immediately after he leaves them to finally make out.
Kor Deno adopts the form of Simon the Hermit to lull Warlock into a false sense of security, but is unable to destroy him while he wields the Hand, and thus the Hand is what Kor Deno demands in exchange for Warlock's freedom.
Now armed with what he believes to be his enemy's greatest weapon, Kor Deno attempts to slay Warlock, only to himself be destroyed by the still-greater might of the Lamp of the Gods. Bad luck, Kor Deno. (Nickel Comics 002, 1940)
Korieg the Sea Devil:
Like Bajah, Korieg the Sea Devil is invoked as a force of evilby the practitioner of a made-up Mysterious Asian Religion, in this case that practised by the inhabitants of a lost kingdom somewhere near Malaysia. No word on any of Korieg's particulars, beyond the fact that they evidently float in water. (Action Comics v1 010, 1939)
