War and Wails: Humanity's Battle Against Martians and Demons in 1917

That's a fascinating alternate history scenario, blending Hazbin Hotel/Helluva Boss lore with early-20th-century sci-fi and cosmic horror! Let’s break it down: **1. Humanity's War With Martians (Soul-less Mollusk Bugs) in 1917:** If Earth was invaded by a powerful but soul-less Martian race in 1917, this would radically alter world history. Given such a threat, historic enemies (Germany, Britain, the US, Japan, etc., in WW1) would likely unite against the common extraterrestrial foe, leading to a massive technological, social, and political shift. Humanity surviving and reverse-engineering Martian tech could kick-start a technological revolution far beyond what we saw after WW1. Think early computers, energy weapons, maybe even rudimentary space travel by the 1930s. Humanity would likely become hyper-vigilant about external threats—including those from beyond the material realm. **2. Demons in Hazbin/Helluva Boss Lore:** Demons from these series routinely manipulate, tempt, and exploit humanity. However, they rely on human souls going to Hell (and some, like imps, have cross-dimensional travel thanks to artifacts like Stolas's grimoire). **3. Human Knowledge And Demon Interference:** If humans learned that demons had meddled in their history—perhaps contributing to the Martian invasion’s devastation, or simply taking advantage of the chaos—resentment and fear toward Hell’s denizens would rise sharply. Moreover, if Martian technology allowed humans to detect or even hurt demons, hunt down gateways to Hell, or shield their souls from infernal influence, they’d want to use it. **4. Allied "Demon Purges":** A post-Martian-war "allied" coalition—now wielding advanced tech and united by shared trauma—might view demons (and maybe even angels?) as one more existential threat. This could trigger: - **Scientific hunts for demonic gateways, rituals, cults, and artifacts.** - **A mix of military and occult task forces (think: 'Men in Black' but for demons),** perhaps willing to venture into Hell itself. - **Humanity trying to monopolize or weaponize demonic power:** Some ambitious humans might want to keep Hell’s power for themselves. **5. How Would Demons React?** - **Hazbin Hotel/Helluva Boss demons are used to preying on humans, so a united, technologically advanced Earth that suddenly fights back would shock them.** - **Princes and overlords (like Lucifer, the Morningstar, or Belzebub) would try to retaliate, but might find the new human tech surprisingly deadly—even to them.** - **Imps, sinners, and lower-class demons might be cannon fodder, causing chaos on the frontline, or even defecting to humanity if offered amnesty or rewards.** **6. Possible Outcomes:** - **Hell's population could be devastated:** New 'soul shields' or 'soul bombs' might annihilate swathes of Hell’s geography or inhabitants. - **Demons forced into negotiation:** With the threat of extinction, Hell’s rulers might attempt truces, bargains, or even reform. - **New coalitions:** Some humans could collaborate with sympathetic demons (think Hazbin Hotel’s "rehabilitation" idea taken global), while extremist factions on both sides call for total war. **7. Long-Term Consequences:** - **The afterlife would fundamentally shift:** As humans shield souls or even prevent them from descending, Hell could face 'soul shortages', undermining its entire system. - **Culture, religion, and world order would change:** With open knowledge of demons, Martians, and Hell—all out in the open—Earth would rapidly evolve into something between a techno-occult dystopia and a new, hard-fought utopia. **Story Hooks/Ideas:** - A reformed demon prince and traumatized human veteran must forge an alliance to stop a worse threat—maybe a Martian-demon hybrid. - The ‘Hazbin Hotel’ is now a front-line HQ for cross-species negotiations, or perhaps a resistance cell for pacifist demons. - Blitzø and the I.M.P. trying to dodge human inquisitors while running "Hell to Earth" extraction jobs for their clients.
