So I've been thinking of the Omegaverse lately and I can't quit thinking about adopting the entire fantasy trope around it.
Like, for example, just imagine...
An Alpha Siren who happens to discover its Omega Reader while there's a cruise ship above, which leads Alpha Siren to follow the ship to port while attempting to gather Omega Reader's attention, stalking you from a distance, leaving little love trinkets everywhere you go, before finally kidnapping you and dragging you need into the dark abyss.
Or reverse it— An Alpha Reader hunting down their Omega Siren, searching the ends of the Earth, diving in vast oceans, countlessly losing your Omega Siren after a single glance, only for your Omega Siren to come to you, half laying on the deck, wagging their tail desperately, wantonly begging for their Alpha Reader to impregnate them.
An Alpha Dragon that captures treasures in their vast abode while waiting on their perfect omega, then happens to discover Omega Reader gathering herbs. We can even turn you into an Omega Witch. Captured by the dragon, fighting for your life, even when your heat kicks in...
Or maybe an Omega Dragon that sneaks up on Alpha Witch Reader in the forest one day and refuses to leave your side. Whines like a puppy, guards like a dog, purrs like a cat, but is as horny as a rabbit when it comes to its heat.
How about an Alpha Naga hunting in the forest, searching for prey for their tribe, then comes across Omega Reader collecting samples, safeguarding the forest, or whatever else you may be doing for planet earth, and takes the chance to observe a new species before falling quickly. Alpha Naga ends up causing your premature heat, kidnapping you from your tent, and hiding you deep in a cave. Your heat gets the better of you but that doesn't mean you won't put up a fight.
Or an Omega Naga that you find as an adventurer that fights you tooth and claw. After winning, maybe it just slithers away or, because of Alpha Reader's pheromones, they go into heat. Maybe you help Omega Naga through its heat intimately, or maybe they are the ones who claw at your shirt, coiling their tail around your legs, their forked tongue kissing your neck and face, even the slippery cocks that end up slipping between its orifice.
Take an Omega Selkie that adores the shore and while swimming to the surface, catches wind of your Alpha pheromones, which leads to the Omega Selkie searching everywhere for you, discovering your swimming form scuba diving or just swimming leisurely, they end up playing with you in their seal form before revealing their true self when you have to leave. It's pretty hard to turn down a tempting and innocent creature that's leaking for you to sate their desires.
Or an Alpha Selkie who dominated the waves, blending in with humans while protecting the seas, they also dare to sift through the human omegas before coming across you, which leads to your rejection and their perseverance until you end up being emotionally and physically attached. Now you’ve got no where to run and no where to hide with Alpha Selkie breathing down your neck and following you at every turn.
Maybe try an Alpha Harpy bleeding from a wound in a fight and comes across you, an Omega Bird Hybrid, before passing out, to which you take them in and clean them up, feeding them, nursing them back to health. Alpha Harpy refuses to leave at the end, declaring themselves your mate, grabbing many courting gifts to give you, nonstop attempts to mate you, aiding you in building your nest and even collecting your meals.
Or maybe an Omega Harpy that is in constant need of affection but refuses themselves from having any contact with it due to their abused childhood, thus leading Alpha Reader, who has Omega Harpy as a pet, to care for their needs, to learn more about habits and behaviors, before attempting to try anything, which leads to multiple disputes that ends bloody for Alpha Reader before you honestly takes care of Omega Harpy through their heat, platonically, thus ending up with them falling for you.. but more slowly and with caution.
We could try an Alpha Cereberus Pack that has lived for thousands of years, most of them mateless and horny, until one night where they meet their perfect little Omega, you, a Cat Hybrid. They're sent to guard the demon that's killing your neighbors, all the while watching you, individually, invisibly, before the demon comes after your Omega Cat Hybrid Reader— which sends Alpha Cereberus Pack feral and ends up taking the demon's life and disappearing with you...
Or an Omega Cereberus Pack that have been abandoned by their last owners or their parents (bc that's the way of life what cruel abusive demons do) and are starved, on the brink of death, when innocent Alpha Cat Hybrid Reader finds them in the wet rain before taking them safely home. You take good care of the Omega Cereberus Pack, even as they snap and growl at your every move, but eventually, they grow fond of you, growing like wild weeds, and, out of nowhere, they've become adults, begging in heat one day.
Maybe enjoy an Omega Arachne that is super shy and scared of others that are not of their kind due to the screams of terror when coming in contact with someone else. Omega Arachne who's lived alone for a few hundred years, succumbing to loneliness.. then they caught a whiff of Alpha Reader's pheromones and suddenly went into a force heat, which causes your rut to come into play, but not until you've stumbled upon their web (in a cave, in a forest, or maybe on a mountain).
Or an Alpha Arachne that has set his eyes on you, an Omega Arachne (or maybe an Omega Lamia) since you were born, watching, waiting, for the perfect time to strike and capture you in their web. Alpha Arachne designs a web for the upcoming mating season and delivers many prey of all kinds for the honeymoon, and even if they don't end up catching your attention, they take matters into their own legs and kidnap you for their own. After a clutch or two, they know you'll be fine.
