Playing God

Summary:

Mewtwo was created to be used. His power, his immortality, even his will were meant to belong to Sakaki, who seeks to bind him once more and reduce his godlike existence to something owned rather than lived.

Ai is cloned again for that purpose, meant only as a lure to draw him back into captivity. She is not meant to be real in the ways that matter. She is not meant to choose, to feel, or to reach for him as a person rather than a tool. But in her presence, something in Mewtwo breaks open. With Ai, there is no demand for power, only recognition. No command, only closeness, trust, and the quiet risk of caring.

This story follows Ai as she awakens to her own personhood, and the bond that forms between them, one shaped by restraint, mutual recognition, and shared isolation. Through her, Mewtwo is forced to confront a life-altering question: whether immortality is worth it without intimacy, risk, or love.

At the edges of the story stands Mew, ancient and watchful, carrying grief across lifetimes.

What unfolds is not a safe, easy romance, but a deliberate choosing of two lovers in a world built to deny them both, a story about love as defiance, and about making an impossible choice.

Notes:

This story previously existed on both AO3 and FF.net under my old alias, Meriah, with the same title, "Playing God" (actually, it is still on there). That version only ever reached one chapter, though, not because I lost interest, but because I was dissatisfied with how it began. I wrote it many years ago, and with time, distance, and maturity, I felt compelled to return to it and make substantial changes. This story has followed me quietly in my imagination for years, and recently I’ve felt a strong pull to finally see it through. Nostalgia, perhaps, but also something deeper.

Loveshipping (Mewtwo x Ai) fanfiction is exceedingly rare, and rarer still are interpretations that attempt to keep both characters recognizably in character. Here, I’ve done my best to preserve their integrity as they exist in canon, while acknowledging that some liberties were necessary. The most obvious of these is Ai being cloned again. I briefly considered an AU where she never died, but that never felt right to me. For me – and perhaps this is the trauma and grief therapist in me speaking – the defining moment that shaped Mewtwo was witnessing Ai’s death. More than his status as a clone, more than his mistrust of humans, that loss is what haunts him most. Removing it would fundamentally change who he is.

I’m also fully aware that when Mewtwo destroyed the laboratory on New Island, the original sample used to clone Ai (who is an adult in this story, thank you), would have been destroyed as well. That does not need to be explained to me. For the purposes of this story, please accept that backup samples existed and were stored elsewhere.

Finally, to prevent confusion: Domino does appear in this fic, and she is important for a portion of it. However, this story exists in a canon-divergent space where the events of Mewtwo Returns never occurred. Instead, it takes place after Mewtwo Strikes Back, as though nothing further in Mewtwo’s canon story followed.

Despite these deviations, I have tried very hard to keep Mewtwo and Ai true to who they are. I love them deeply, and they will always be my OTP.

As for the new pen name… there’s no dramatic reason. To be honest, I lost access to my old accounts on both AO3 and FF.net. The email addresses tied to them were synced to an old phone number, and I can’t even reset the passwords because Google can’t verify me. So… new account, new alias, same story. Yay.

Thank you for reading, and for meeting this story where it is now.

Writing Style Note:
This story is written primarily in third-person, past tense. There are occasional sections written in first person, which always apply when Mew is speaking and, more rarely, when the perspective shifts to Ai. Mew’s sections also shift into present tense, which is an intentional artistic choice and should make sense in context. I’ve kept these perspective and tense changes as limited as possible, since I’m aware they can be confusing, but they felt necessary for certain voices and emotional beats.

Limitations:
The AO3 system doesn’t seem to support prologues and epilogues, which is why the formatting here looks a bit odd (“Chapter 1: Prologue: The Legend of the One Who Let Go”). Unfortunately, I don’t have control over that because AO3 handles the cataloging automatically. Please ignore the strange formatting.

Chapter 1: The Legend of the One Who Let Go

Chapter Text

Prologue:
The Legend of the One Who Let Go

The night has grown quieter. Or perhaps it is I who have learned to listen differently.

I hover in the air of an old forest that remembers more than it reveals, its roots knotted with centuries of memories, its mycelium humming what it will never speak. Dew settles along the blades of grass, feeding the small lives hidden beneath in the understory.

Careful not to reveal my true form, I let a faint resonance ripple outward, only enough to soften perception, to ensure no eyes will catch what follows. No one sees me. That is as it should be. I shift, drawing myself smaller, lighter, until I take the form of a Taillow and settle into the sheltering green of a hemlock. I fold two narrow wings against my sides. Here, I rest. I wait. I always wait so I may observe what stirs and unfolds around me, the way I have always done.

For a long moment, the forest breathes undisturbed. Insects click and whisper. Leaves shift against one another. Somewhere below, water droplets slip from leaves to sink into the soil. Everything knows its place.

However, not long after, the quiet is broken by a sound I know well: humans. Pokémon trainers. Their voices carry too easily, ending the hush, sending the wild things retreating deeper into cover. The night seems to tighten around itself.

“It’s late. We should make camp for the night. I mean, we should’ve done it hours ago,” a girl complains, her frustration echoing into the trees.

“Not my fault your directions sent us the wrong way,” a boy responds.

“Always the excuses! You didn’t need to go chasing that Skarmory, which you didn’t even catch… again.”

“I need a steel type. And you’re not exactly the better trainer here.” He flips open a case, angling it so the gym badges catch the moonlight. “Last I checked, I’ve got more of these than you.”

She rolls her eyes and says, “Oh, whatever.”

A third voice joins them, older, steadier, and shaped by patience. “Are you two going to continue your daily lovers’ quarrel or are you actually going to help me pitch the tents?”

Their argument dissolves into movement. The three adolescents settle beneath the tree that shelters me. Knapsacks are dropped and fabric is unfurled. The oldest kneels, rubbing flint against metal, and the spark sputters before catching. He struggles with the art of fire-making. Smoke curls in slow patterns until the fire finally comes to life with a tentative crackle. I sense a Combusken waiting in his Pokéball, asleep, and cannot help but wonder why the trainer did not allow the Pokémon do what it comes naturally, and why he insists on making the task so much more laborious than it needs to be.

Meanwhile, the younger two people move side by side, pitching tents in a slow, easy rhythm. Their hands brush briefly as they adjust the poles, fleeting and electric, which makes the girl’s cheeks turn red. She turns away, shy, while the boy chuckles. They pretend not to notice, as if denying their obvious attraction to each other.

The meal comes next. A metal lid lifts with a clang as steam rises in pale waves into the cold autumn evening. The girl stirs kibble and berries into bowls for the Pokémon, who are called out from their Pokéballs and settle to eat. A Kirlia glances up, sharp-eyed, catching the trace of me. The younger trainer flinches, a blaze of readiness in him, almost spilling his stew, poised to battle.

The psychic senses my presence. Fortunately, I am far stronger, more practiced in bending such energy. It cannot pierce through my disguise, only noting a faint dissonance. Still, it seems convinced I am indeed of this temporary form, nothing more than a common species.

“Oh, it’s just a Taillow,” the trainer sighs, settling back into his meal, disappointment soft in his voice.

Good. As it should be. And still… if only he understood the majesty in being something so ordinary. How effortless it is to exist, to be loved, to just be. There is power in simplicity. There is freedom in the everyday.

They are staying until at least daybreak.

I continue to perch from the tree as a slight chill catches my wings.

The forest does not return to what it was before. It never quite does. It adapts and watches as much as I do. I shift deeper into the hemlock branch, needles closing around me for security and warmth, and listen. There is nothing remarkable about this moment. And yet, something in me remains curious, as though the night itself has leaned closer, attentive to what will follow.

As the humans eat, the eldest begins a ritual as old as their kind: conversation with stories traded over food. Another ordinary act. Another one I find myself drawn toward, yet cannot join, for to do so would reveal too much. He leans closer to the fire, warming his hands. In the light, I can see he is barely past childhood, standing on the threshold of adulthood. When he speaks, it is to break the soft sounds of eating.

I wonder which story he will tell.

Sometimes humans speak of champions and gym leaders, of heroes fallen and villains undone. Sometimes they speak only of their dreams. Sometimes, they drift into myth.

They celebrate Ho-Oh, who lifted three lives from ruin into magnificent beasts. They revere Lugia, who stilled the embodiments of fire, ice, and lightning to save the world from destruction. They speak of Celebi, always benevolent, who renews the forests through time itself, and a friend of mine. I could go on — so many gods, so many legends, each one held in human awe, each one a story they will never tire of telling.

And, of course, they speak of me.

Goddess. The Great Ancestor. Mother of All. She of the Most Holy. Light of Creation. Bringer of the Life-Rains. She of a Thousand Names. The Hidden One. She of the Sun. The One Who Holds All Secrets. The Immortal One. Titles that sound hollow on my tongue.

To scientists, I am the Progenitor: a living repository of shifting DNA, the blueprint of all life itself. To the first peoples, I the Goddess, both angel and demon, the womb of creation and the shadow of oblivion, the one who calls forth life from after natural disaster, but who could, if I willed, unravel it all.

I have been pursued since humans first walked the earth. Worshipped by ancients in song and shrine, set at the center of sun calendars. Obsessed over by the modern world, even when their desire risks their own demise.

But to me, these names, these stories… they are nothing.

I am only myself.

I am Mew. And I do not care for tales about me.

I care about another one.

“Have you heard the story of the Pokémon who let go?”

Oh. Yes. This story. This one.

Humans are the storytellers now – through song, poetry, and voices carried across generations – and one tale rises above the rest: the legend of a Pokémon who chose to let go. Mewtwo. They call him wise. They call him powerful. They do not call him loved.

I do.

“We’ve all heard it,” the younger boy says. “Since we were kids. I even had a book about it, well, from a whole collection of myths. I like the other stories better, the ones about epic battles, gods fighting.”

“But it’s such a beautiful story,” the girl adds, her voice reverent and dream-like. “I think… I think it’s my favorite.”

“Of course it is,” the boy mutters, edged with sarcasm. She casts him an icy glare.

“I want to tell it again,” the eldest says. “Tonight is my turn to tell a story.”

From the shelter of the tree, I fly lower on silent wings and choose a nearer branch. I move as any Taillow might by scuttling along the bark, settling my weight, then smoothing my feathers. I give no sign of interest in the lives unfolding only feet below, presenting myself as just one common, unremarkable, common creature among many, belonging to the forest and nothing more.

And I listen.

The adolescent recounts the legend, shaped by countless mouths, worn smooth by repetition. Within minutes, boredom settles in. The story has been cleansed of its weight, softened for easy consumption, stripped of its truth. Humans prefer their myths tidy. The abridged version, the palatable one: A Pokémon chooses mortality by deciding to have the span of human years, if it means to be loved. A deity watches, approving, unmoved. But that is not the truth. Not all of it.

The truth is a wordless ache; a lesson etched in the spaces between heartbeats. I have learned that letting go is not always victory. Sometimes it is not release at all, but the beginning of understanding.

I sigh, disappointed. I have heard this version – no, countless versions – too many times to count. None of them capture the whole of it. The cost. The depth. What it demanded of him, her, and me.

It is a secret only I know.

Or perhaps I am simply the only one capable of holding its gravity.

There are other things the humans will never know, too. A name spoken once, tenderly, as if it could break under the pressure of its own magnitude. A word I had not expected to hear: Mother. It was not merely sound. It was grief, recognition and a connection, braided into a single thread. I have carried that moment longer than any lifetime, guarding it like a holy flame.

The human retelling polishes it, trims its edges, and repackages it. They do not know how love can threaten even me, how it can pierce the immortal and leave it hollow.

Yes, it happened to me. The full truth is – goodness, how do I begin to explain it all?

Time softens its hold on those who do not age. Eras move like tides, each return familiar, although never quite the same. I have witnessed stars stir to life in their nurseries and later fade into nothingness, the span between those eons no more than a sigh I exhaled. I have watched continents shift, oceans retreat and reclaim their coasts, civilizations rise and fall like condensation on glass. Loss is not foreign to me. It is crocheted into the great cycle of existence, bound alongside memory, and beneath it all vibrates the sacred yet earthly power of what it means to have been called Mother.

There was no thunder when that word was spoken. No falling stars. There was only the choice – the final, irrevocable decision – and the name that bore it. Mother. Simple enough for a child to speak. Vast enough to unmoor a god.

And nothing prepared me for what followed: a faint disturbance tremored through space-time, pointless in duration, yet the catalyst which changed everything.

I felt him change.

Some moments refuse to be compressed by eternity. I remember the first warmth of it, though I had no word for “warmth” then; no expectation of it, no permission to feel it. I remember watching carefully from afar, holding still, sensing the quiet tension of something not meant to feel vulnerable being drawn toward it anyway. It frightened me. It drew me closer.

He once prided himself for being the strongest Pokémon, for saying he did not feel, but yes, he did.

I do not often intervene. I observe. I remember. I advise, when it is asked of me. But something small and insistent pressed against the edges of my awareness, and I could not turn away. I do not know whether it was mercy or curiosity, longing or fear. Perhaps it was all of them coiled into one.

I am the witness. I am the keeper. And yet, I cried. I cried. I did not know how to stop it or even that I could even do something so raw, saved for mortals. I did not know I could feel this: the pressing weight that bloomed in my chest, nor did I recognize the taste of saline on my tongue or the stinging warmth of liquid on my fur.

In all my endless ages, never had a single moment stretched and quivered, carrying within it the fragile pulse of mortality, of being able to fully feel. As the water traced down my cheek, I began to comprehend what all others could so freely experience.

I have been present at the births and deaths of galaxies, and felt nothing beyond a distant, passing interest. I have borne witness to grief in all its forms: a Pikachu sobbing when his trainer turned to stone; a wife mourning her husband as dementia hollowed him into someone unrecognizable; lovers drifting apart; a Lycanroc pack howling beneath a moonless sky for one of their own; parents choking on tears as a child was released from the ventilator which kept her breathing. Heartbreak. Rejection. Broken vows. I have seen the heaviness of loss bend bodies, the shock of despair drive grown men to their knees, fists raised toward unresponsive deities, tears cutting through them… and still, it stirred nothing in me. I only wondered, from the distance of immortality, what it might mean to grieve.

And now I know.

Grief and love are reflections of one another.

That first tear – the one lost in the story retold – remains with me. It is mine alone, and yet it is everything. It is the outline of a moment I refuse to release, a tiny, enduring fragment of what it means to exist under the rule of impermanence rather than eternity. Sometimes the story returns only in whispers, when I take the form of something ordinary and listen from the margins as conversations happen, as I do now, stretching these small blue Taillow wings. And I know, with a certainty deeper than any truth I have carried, that every song, every myth, every poem has overlooked what mattered most. I was changed… by love.

I remember his eyes: violet, clear, unguarded. Not afraid. Alive with discovery. And self-certain, in a way I had not seen before. I remember the presence inside me shift and tremble, brushing against boundaries I had never crossed. He was neither Pokémon nor human, but something held in the space between, bridging what should not have met. And within that in-between lived a promise to himself.

Or perhaps he was both.

I have witnessed love in every form. I have followed its patterns, its psychic echoes, its fleeting contacts that alter entire futures. Still, nothing prepared me for this: the gentle pull toward change and the vulnerability of loss. I, who had never feared it, came to understand it in that one exchange.

The humans speak of the choice as though it were simple, of wisdom as if it arrived without issue. They leave out the uncertainty. They do not speak of the goddess who learned herself in the act of watching, nor the tear that impressed mortality upon something eternal. That truth is too abstract for their legends to carry.

So I keep it.

I carry it with me, unchanged, and will do so until the end of days. For even I, Mew, who was indifferent to love until that day, have been changed by what it means to give… and to let go.

Soon, I will tell the story as it truly transpired. Not as it was refined into the written word, but as it was experienced: uncertain, fragile, ripe with risk. There will be no immaculate ending. No moral.

One of the trainers turns her head toward me. “Weird, that Taillow hasn’t left,” she comments.

Another shrugs, “nesting up in that tree, I guess.”

“Yeah,” the first says, already distracted. “Must be where it lives.”

Their conversation resumes. The fire crackles, drifting embers through the air around them. The story moves on without me.

I watch as the flames deepen into amber, and even that feels laden with meaning beneath my gaze. Her resonance – extraordinary, singular, a glorious amber and white – was something even I had never witnessed before, and may never witness again, and it was that luminosity he could not turn away from, no matter the cost.

I stay for only three breaths longer. Then I lift from the branch and vanish among the shadows, knowing that mortality is not a burden, but the gift that shapes all hearts. It is a freedom in the everyday that even I, who remembers when the earth was forged by rock and fire, will never know.
