As if we humans don't have enough to worry about from preying on
each other, whether in brutal war or heinous criminal acts, humans in the fictional world of comic books were subject to attack and slaughter by primeval forces that regarded primitive man as no more than indigenous beasts to be subjugated and abused or killed without regard. It seems ancient Earth was very popular with malevolent beings that paid little to no heed to their treatment of humans and whose rule of the Earth would last for ages, eons, millennia, or whatever lengthy term suited the story's writer. Given such a vast time span, you would think the ruling periods of one or two of these despotic entities would have overlapped, resulting in a turf war that would have laid waste to the world and its unfortunate inhabitants--nor do we ever seem to learn of such horrific times from historical tomes, but rather from the vile creatures themselves who somehow manage to return with the intention of picking up where they left off.
Following you'll find a brief PPC overview on the subject, in no particular chronology or preference. You'll note certain omissions that didn't strictly conform to the topic
(with one exception)--e.g., evolutionary tinkerers such as the Celestials, the Kree, Mr. Sinister, Apocalypse, et al., as well as latter-day threats along the lines of Belasco, Kulan Gath, the Serpent Men, and others acting on behalf of their masters. Nevertheless, do chime in if you feel there is a party that should be represented here--I'm definitely not up on
all of the ancient horrors that tried to stake their claim on our world back in the day... er, eon. ;)
Though speaking of the Celestials, we can start with one of their discarded failures,
the Deviants, who went on to conquer the entire world and enslave mankind for the duration.
Again, word of the ark has been passed down--but nothing about a race of misshapen monsters that kept humans as slaves and ruled in tyranny for centuries? How does something like that slip through the cracks?
Then we have
Chthon, one of the Earth spirits who wasn't content to "step down" from an active role as did his sister, Gaea, but instead scripted one of the most evil grimoires in existence,
the Darkhold, to pave the way for his return. Chthon, unlike the others we'll see listed here, didn't so much as gain a foothold on our world but, like Dormammu, didn't want for lack of trying.
We have Chthon to thank for vampires, werewolves and the like--as well as for
the N'Garai, our next entry:
As we can see, creatures such as the N'Garai had many thralls such as
Kierrok to act in their interests. And while the individual known as
Psyklop acted to appease the so-called "Dark Gods," it turns out that Psyklop's race also had advanced to the point of ruling the Earth in ancient times.
And let's not forget about
the Undying Ones, who ruled the Earth for "unnumbered ages" under the control of their master, the Nameless One:
Earth also fell to
the Four Horsemen of the Apocalypse, the vanguard of a race which ruled the Earth for an indeterminate length of time until they were vanquished in a 100-year war by
another race that presumably took their place as the planet's rulers.
(That's a
lot of mushroom clouds going off on ancient Earth. You would think
one of them would be noted in a scroll or two somewhere.)
Which brings us to the last of our tyrannical abominations, this one eventually slithering its way into New York City:
Before ripping into present-day Times Square, however,
Shuma-Gorath was lording it over prehistoric man, before the time traveler known as
Sise-Neg dealt it a setback.
It's a wonder that you and I are even here to talk about all of this, given the number of times the human race has been decimated by those creatures who held our species collectively under their thumb (or what passed for a thumb) over the ages. It's also a testament to the resiliency of the Earth itself, having weathered cataclysm after cataclysm and no doubt giving Gaea cause to yearn for a long vacation. Somehow the Inhumans, who were
present during prehistoric times, managed to isolate themselves from these conflicts, when you'd think their advanced race would have been a prime target for the Deviants and most of the others listed here (we could say the same for the Eternals); surely their historical records would have complete accounts of global conflicts which occurred on the scale of what we've only seen here in glimpses. Then again, perhaps we humans are better off not fully knowing the grim travails suffered by our unfortunate ancestors.
