Hyperdimension Neptunia is owned by Compile Heart, Idea Factory, Sega and whomever else worked on it.

Playing with AI is dangerous, it gives me ideas.


Letting out a yawn as she stretched after waking up from a nap, Neptune wandered out into the living room. "Hey! What's the..." She trailed off and tilted her head, blinking a few times as she saw IF and Compa in the living room. That wasn't unusual, but what was was the two people with them. "Um, Iffy, Compa, did you two have an adventure in another dimension and meet another version of yourselves?"

The girl next to IF looked almost like her, except for having blonde hair, amber eyes and a D-pad hair clip in her hair. She was wearing a black and purple jacket with red trim. The girl next to Compa looked like her, except for the D-pad hair clip in her hair and the purple tips of her hair.

"No, Nep..." IF said slowly as her eye twitched for some reason. "These two claim that..."

"MOM!" Both of the new girls yelled and tackled Neptune to the ground with a loud thump.

"Somehow you're their mother." Compa finished while smiling. "And that I'm her mother. And Iffy's the other one's mother too."

Neptune blinked a few times owlishly. "Oh, a time travel plot, great."

IF continued to twitch. "Nep, I have one question for you." Neptune nodded. "HOW THE HELL DO YOU GET ME PREGNANT?!"

"Niffy..." The Compa-look-a-like looked at the other girl. "Your mother seems stressed."

"I have no idea Comne."

"...And apparently you were in charge of naming them." IF muttered.

"And what's that supposed to mean?" Neptune asked.

"Oh, no, mom, those are our nicknames for each other." Niffy said and stuck her tongue out. "And, um... Time travel, well, maybe... I think we ended in an alternate timeline."

"AHHH!" Comne jumped up and pointed a shaky finger at Nepgear. "It's the evil mad scientist Nepgear!"

"Goodness gracious, what?!" Nepgear yelled with blank white eyes.

Niffy grabbed Neptune and jumped back. "Mom! We have to get away from her! She'll capture you and your friends, chain you up in her basement as she tries to take over the world!"

"What?!" Everyone else in the room yelled while Nepgear teared up.

"But I haven't done anything like that yet! Other than that time I got hit with the insanity beam and tried to make a robot army of all the CPUs." Nepgear protested.

"Yeah, that was quite the crazy adventure." IF nodded. "Too bad the reader didn't get to see it."

"Uh oh, Iffy's really mad!" Compa yelped with blank white eyes. "She's breaking the fourth wall!"

Comne was pulling Compa and IF away from Nepgear. "She said that she wanted everyone to love mom and did something stupid crazy and that's how we were born! But the world was falling apart! We found a way to a place where evil Nepgear hadn't ruined the world and had to stop her!"

"Technically, she wanted everyone to love mom's cuteness." Niffy pointed out and Comne nodded.

"Oh come on! That was me being silly in one of the spin-off games!" Nepgear yelled and waved her arms up and down in protest.

"Yeah! It's not her fault that the writers were having a funny moment." Neptune said in agreement as she got away from the new people. "So, come on, Nep Jr. wouldn't do any of that."

"But she did!" Biffy protested and pointed at Nepgear, who looked like she wanted to cry.

"AHEM!" A new voice spoke up and everyone turned to see Histoire glaring at them all. "Why don't we all... CALM DOWN!?"

Everyone's heads tilted to the side as their hair blew to the sides and their eyes went white and blank.

"Sometimes I forget that miss Histoire has a set of lungs on her." IF muttered.

"...Who's that?" Biffy asked and everyone blinked in surprise. "Uh..."

"So apparently in your world Histy doesn't exist, Nepgear went evil mad scientist and somehow made me a mother with Iffy and Compa?" Neptune blinked several times as she thought about it.

"That explains everything then! Histy would never let Nep Jr. go all evil CPU on us."

"Except in the bad endings." Compa pointed out helpfully.

Histoire coughed into her hand. "Be that as it may... This is not your Nepgear. Why don't you two spend some time here and get to know this world before you go back?"

"...Do we have to?" Comne asked with tears in her eyes. "This world is nicer!"

"...Actually," Neptune suddenly blinked as a grin came to her face. "If Nep Jr.'s being evil in your world, I know who to ask to fix everything."

"Wait, you don't mean..?" Nepgear gulped and hoped that she was wrong.

Neptune's grin got wider.

In an alternate future timeline...

"Oh, Neppy!" Iris Heart grinned as she continued to play with the mad scientist who called herself Nepgear. "You shouldn't have."

Neptune just smiled nervously. "Just remember not to break her too hard, okay, Plutie."

Both Comne and Biffy's eyes were white and blank as their faces turned blue. As bad as the evil mad scientist could be, they had no idea that there was a CPU capable of making her look nromal and meek.

At least after Iris Heart was done with her, the world got back to normal.

Somewhat. But that's a story for another time.


Tried to get an image of Compa and IF in bikinis and instead got what could only be described as Compa and Nep's daughter and IF and Nep's daughter. So... Ideas came to me and I had to write something. Then I was like "How do I resolve this?" and the problem fixed itself. It's just a silly idea, hope you liked it.
