You'll go for Arceus. Go big or go home.

Chapter by Aurora

You allow the temptations filling your mind to overtake you. If you could somehow manage to successfully take over Arceus herself, you would become what was, to your knowledge, the top god of this world. There would be no one above or below who could question you. Maybe it was a bit presumptuous to think that you would even succeed in getting that far, but you also consider that you managed to achieve this. Controlling one of the creation trio, and having another completely under your spell.

You feel extra confident, and decide that you just had to go for Arceus. If nothing else, you had nothing to really lose, so it was worth making the attempt. You look towards Palkia, a smirk forming on your face, as you respond.

"Yes Palkia, I want to meet and take over Arceus, if you don't mind helping with that." You say, knowing full well that she'd agree to this, after the trance you've put on her. "Of course Mistress! I'd love to help you take over our mother! But of course, we'll need my sister here with us, as both our energies are required to summon her properly!" She explains. You already have a solution to this. You know from your experience that you should be able to do to Dialga what you did to Palkia, even as a spirit.

"I already have a solution for that Palkia, just give me one moment." You say, as you close your eyes and try to figure out how to leave Dialga's body. You sit down on the floor, so as to not let Dialga collapse and get hurt when you leave her, and close your eyes. You begin to desire leaving the time Pokémon's body, and as you focus on this desire more and more, you feel yourself losing sensation throughout her body. You feel your spirit separating from Dialga, and within just a few minutes, you open your eyes again. You look down, and see yourself as a spirit once more!

You look over at Palkia, who still seems to be in the trance from before. It doesn't seem like she can see you, but it also doesn't seem like your effect on her ended when you left Dialga. Good. You see Dialga, flat on her back on the floor, seemingly unconscious, but breathing as her mind comes to. It takes a few minutes before she finally begins to come to, and as she does, she groans. "Ugh... Wh-What..."

Before she gets anything else out, you immediately hover over to her, and speak directly next to her head. "Dialga, you will allow yourself to fall into a trance." You say. You wait to see if it works, and you watch as her eyes begin to droop as well, just like before! You were still surprised, but you certainly weren't complaining!

"Dialga. You know I am a spirit that wishes to take control of your mother, and you are more than accepting of this. In fact, you actively desire for me to do so. Imagining me in control of Arceus makes you happy." You say. You also make sure to add the same conditions you added to Palkia, her loving you and everything you say and do, including calling you Mistress. It would be true again soon enough anyways.

Once everything is done, you set the trance in place, and once again, Dialga shakes her head, and begins looking around as if to search for you. "Oh, Mistress is not here. Hello Palkia! Did Mistress call you here as well!" She asks. Palkia replies. "Yes, indeed dear sister! And she wants us to call our mother so she can take over her body!" Palkia speaks with joy in her voice. Dialga follows suit. "Ah, yes, good! I'm looking forward to this!"

As you listen, you make sure to speak up once they are have a break in the conversation, making sure to be close to both of them so they hear you. "Now then, once you both summon Arceus, I need the two of you to act as a distraction. I'm going to sneak around to her back, and try to take over from there. Once she starts shaking, I need you two to hold her down for as long as you can, and give me time to take over, understood?" You request their assistance in this task, and they both nod, eager to please.

"Yes Mistress! Now then sister, let us summon our mother!" "Indeed. We will start now Mistress!" They both say with smiles, as their bodies begin to glow. You see the lines across their bodies glow as well, two different kinds of energies flowing through them as well. You don't know exactly what they're doing, but if things went well, it wouldn't matter too much in a bit. You'd just learn from the one who knows everything there is to know.

As they both glow, you notice a small orb of light begins to form between them. It grows bigger with each passing second, before it reaches a point where it's larger than either of them! Once it does, you notice a figure begins to appear, fading in and out, more in than out as time passes. As this happens, you make sure to start moving around them, placing yourself behind the figure so as to not let them notice you. You weren't sure if they'd even be able to see you, but you didn't want to take the chance with this.

Before long, the light bursts outwards, blinding you and the two goddesses of space and time before you, as you cover your eyes, trying your best to stay out of sight. The light soon begins to fade, leaving behind trails of golden dust, and now, standing before you, is the beauty you were trying to bring forth

You gaze upon her white and gold visage in awe. She really was here, Arceus. And she was actually extremely good looking... her breasts had to be just as big as Palkia's, and she had a rump to rival both of the sister's. It made sense, as you knew Dialga and Palkia were made in Arceus's image, but even still, it was a lot to process.

You don't let her godly presence overwhelm you though, this was your chance! It was now or never. As Arceus lands, she looks at Dialga and Palkia, curious as to why they both summoned her. They both speak up before she gets the chance to ask.

"Hello Mother!" They say in unison. "We called you here because we, er..." Palkia starts, but seems stuck, unable to think of what to say that would serve as a good distraction. Dialga jumps in to try and help. "We called, because we had something important we needed to ask you!" She says, blurting out something that sounded right. Arceus looks confused at her children, but nods, and speaks, allowing you to hear her voice, deep and sensual, powerful, but still very clearly feminine. "What dost thou need answered, my daughters?" She speaks in... old timey english. Fair enough you suppose, she's existed for millions of years more than likely, if not longer, so it makes sense she would still have some habits from a long time ago.

As Dialga and Palkia speak to her, you begin making your move, slowly creeping up to her back, getting closer. Once you were right up against her, you didn't waste a single second, and immediately lunged for her back! Arceus lets out a gasp, and begins trying to grab whatever has tried to intrude on her body, and as she does, Dialga and Palkia nod to each other, and grab hold of Arceus, pulling her down to her knees. She writhes, but is unable to speak as your spirit digs it's way into her body. You feel a very clear resistance, and it was genuinely feeling like a battle of wills inside her.

Palkia and Dialga watched on intently as their mother struggled against them, unable to question why they were suddenly attacking her. Within, you kept pushing forward, deeper inside. You refused to give up, you had to take this opportunity, and become the one on top. Your will far exceeded her own, as you pushed ever onward. Before long, Arceus's eyes would begin losing their glow, her struggling would slow to a mere squirm every so often, and soon, she would go limp entirely, her natural glow fading...

You felt yourself floating in a sea of golden light, yet unable to see in said light. It was blinding, but even without sight, you could still feel. Somewhere close, you could feel it. The core of Arceus herself. You begin swimming towards it, the light warming you, making you feel so powerful... you got closer, and closer, until... everything goes dark.

Voices. You hear two voices above you, calling your name. Your vision begins to fade back in, and you see a blue figure, and a pink one. Palkia and Dialga stand over you, worried expressions on their faces. "Mistress?! Mistress, did you succeed?" They ask intently, as you blink a few times. You struggle to move, but you manage to raise a hand, and see that it is covered in soft, white fuzz. You look down, seeing those same white breasts coming from your chest, and you certainly feel the golden rings that wrap around you belly, arms and neck. You had succeeded, somehow. You took control of Arceus herself. Light returns to Arceus's eyes, and your vision fully returns.

You move, and begin to stand. You look down at Dialga and Palkia... Down? Right, Arceus was just slightly bigger than them. Or, rather, you were just slightly bigger than them. You smile, as you speak.

"Yes my 'children'. I have succeeded in appropriating this body, as I'm sure you'll be glad to know." You say in a sing-songy cheerful tone. They both smile, and run up to hug you. They both feel odd, but nice against your chest. Warm even. "Oh Mistress, you look so wonderful inside our mother!" "I agree! You are perfect!" They both praise you, making you feel really good actually.

You take a few moments after this to acquaint yourself with this form. You feel over your large breasts, as well as your big, shapely ass. It was all absolute perfection, not that you expected anything less. Your new body was amazing nonetheless. You were Arceus. You were the top Pokémon now. You were the Alpha.

"Now that you've taken over as our mother, what will you do now Mistress?" Palkia asks eagerly. She makes a point. You can do... anything now! You bring a hand to your chin, and ponder. First, you suppose, was deciding what to do with your new 'children'. You could turn them back to normal, or leave them as they are now.

Some suggestions:

•Leave Dialga and Palkia under your trance. Go have fun with your new body

•Return Palkia and Dialga to normal, and pretend to be their real mother

•Return Palkia and Dialga to normal, but keep them believing you are their mother
