Scenario 1.
Spoiler: show
Imagine your favorite pred swallowing a bunch of previous prey to grow stronger to ascend to a higher form or a greater power level, until another (favorite) prey of yours who happens to be a friend or family member of all the prey your favorite pred has swallowed has had enough and decides to fight your favorite pred to avenge them and dish out some heavy moral punishment and punitive justice towards the pred. Your favorite prey could either be single or two people/beings. Your favorite pred taunts and mocks your favorite prey about how all their friends are in the former’s belly and how they’ll all be a part of them forever and that it’s the latter’s turn to share their fate. Your favorite prey train hard to grow strong enough to challenge your favorite pred in combat.
Your favorite pred initially has the upper hand over your favorite prey treating them like trash until your favorite prey somehow manages to turn the tide via some radical power-up or deus ex machina (or if there are two prey present, a fusion dance into a far stronger being is optional) and no matter how much your favorite pred tries to regain their dominance and confidence and what (conventional) tactics/attacks they use, your favorite prey just keeps beating the shit out of the pred just with Super Buu vs SSJ Vegito.

Scenario 2.
Spoiler: show
Imagine your favorite pred successfully transforming your favorite prey in question that’s fighting the former into a candy or some food small enough to swallow via their mouth (magical or fantastic physics notwithstanding), only for your favorite prey to still be able to retaliate and fight back pretty well while in in a seemingly weaker smaller form and despite not being able to come close to killing or otherwise putting down your favorite pred for a ten count, your favorite prey is still able to injure and outpace the former in pure speed/agility from every angle, humiliating them. Your favorite pred decides to give up and transform the latter back into their normal self to be able to physically land a hit on them at all. Just like Candy Vegito vs Super Buu.
Scenario 3.
Spoiler: show
Your favorite pred is still getting slapped around by your favorite prey and the latter threatens to finish the former off for good, but your favorite pred tries one last trick up their sleeve which is a secret absorption technique of some type or they seemingly trick the prey that’s been handing them their ass into finally getting swallowed or eaten whole and when such tactic finally spins the table back into the pred’s favor, your favorite pred prematurely assumes victory by laughing so hard and celebrating but notices that they haven’t gotten any stronger or changed at all before commenting that your favorite prey was harder to eat than they thought and that they’ll take a while to digest/absorb.
But little does your favorite pred know that that your favorite prey is still alive and unconscious in one piece inside the former’s stomach, undigested and unabsorbed, and that your favorite prey only allowed themselves to be swallowed/eaten so they can search and rescue all the other friends that got eaten and absorbed by your favorite pred by exploring their stomach and digestive system on their own. If your prey was a fused being, they defuse as a result of your favorite pred’s digestive acids or stomach atmosphere. They both walk and argue together inside their new hazardous organic environment like Goku and Vegeta inside Super Buu. Your favorite prey is/are also now extremely small inside and is also exponentially weaker by extension.
Scenario 4.
Spoiler: show
Your favorite prey keeps exploring your favorite pred’s body until they fall into the latter’s main stomach into a huge pool of acid/gastric juices where other food and victims are still undigested in one piece are being submerged and slowly being digested. Your favorite prey is sinking into your favorite pred’s stomach acid and slowly gravitating towards the hole to another part of the body like a whirlpool/vortex, so the prey fires a blast against the pride’s stomach walls, thus giving your favorite pred a tummyache with the latter complaining of indigestion and cursing the prey and the pred starts to realize that the prey is still lurking in their belly somewhere and wonders why the still haven’t been digested yet. Your favorite prey goes into another part of the pred’s stomach or digestive system (like the Intestine) with the stomach wall healing up shortly afterwards due to the pred’s regenerative healing factor, and explores the innards more.
Scenario 5.
Spoiler: show
Your favorite pred has living sentient stomach acids or digestive enzymes in the form of a sexy humanoid figure or whatever living inside your favorite pred’s stomach functioning as guards of some sort (think of that scene from Cow and Chicken episode “Journey to the Center of Cow”) and your favorite prey witnesses their sheer dissolving power and capabilities by enveloping and melting the other food and victims inside quite fast. Or some sentient creature living inside eating intruders or other victims like those worms inside Buu (but I prefer the former option).
Your favorite prey squares off against the sentient acids or enzymes and engages in a fight for survival, the latter either wins and digests your favorite prey to death or your favorite prey almost gets digested but pushes back strong enough to narrowly win or survive and even communicate with the acids and enzymes themselves after the latter is impressed with the prey’s might and tells your favorite prey where all the other friends they are searching for are located as acquired intel.
Scenario 6.
Spoiler: show
Your favorite pred still has a stomachache is in a rush to find a bathroom or somewhere to try and excrete your favorite prey out, while the latter notices the area around him rumbling like an earthquake and as your favorite pred is in the process of evacuating their bowels, your favorite prey retreats to another part of the prey’s stomach or body to avoid being shat out. After your favorite pred, is done answering their nature’s call, they will still assume that your favorite prey has been digested and even absorbed and their physical remains have been expelled from their system (when they obviously haven’t) and will comment on how your favorite prey was a pain in the ass to deal with and how this universe could have such strong stubborn guys like your favorite prey before moving on and bragging to the world about how they’re the strongest being in the multiverse.
Scenario 7.
Spoiler: show
Your favorite prey is still exploring the deeper depths of your favorite prey’s stomach and has finally located all their friends still alive and well and start wreaking havoc inside to get out, while your favorite pred gets more tummy aches and starts to manifest a smaller version of themselves inside their stomach to combat your favorite prey and their friends as a reaction, a dramatic final battle ensues and your favorite prey’s avatar uses his own body to manipulate the environment and surroundings to troll your favorite prey and their team of friends in every way possible like Buu did to Goku and Vegeta inside their heads. Your favorite prey’s avatar acts all annoying and irritating to your favorite prey and their friends to the point where the latter tells the former to “shut the fuck up” or some sort of insult before threatening to destroy the former with a final attack of their own. So by some deus ex machina, your favorite prey and their friends finally adapts and pulls off their great final assault to seemingly defeat and destroy your favorite prey’s avatar form.
Scenario 8.
Spoiler: show
Just when your favorite prey and their friends think they’ve won against your favorite pred and wants to get the fuck out of here, your favorite prey’s internal avatar respawns out of nowhere sneaking up on them and catches them all off guard by using the walls or floors of their stomach to trap them inside the pred’s body laughing and telling them they’ll all be digested or become a part of them and your favorite prey and all their friends are killed or knocked unconscious via some methods and all their bodies finally get digested or absorbed (or both) and thus your favorite pred grows exponentially stronger than before and is happy/jolly and smugly laughs in victory and is now the strongest being in the multiverse and celebrates their newfound strength and dominance through terrorizing the world and destroying everything in sight as well as eating every other living being in sight with no one to stop them in their way of overthrowing the entire cosmos.
(or Alternate Ending: Your favorite prey and co. narrowly finds a way to escape your favorite pred’s body alive and what happens after is up to all of you from a creative or imaginative storytelling perspective).
Overall this is the best type of vore fantasy story I'd like to see involving preds (and to a lesser extent, prey) that I love or get turned on by the most.
Let our brainstorming session begin folks!
