Undertale Multiverse with DreamSwap

Day one:

Don't tell anyone this, but I'm GoInG tO f***iNg DiE-

Okay. Sorry. Uh, my name's Nightmare, I'm the Lord of Dank Memes (insert trademark), and also the main target of Justice Reigns, the most powerful organization in the multiverse.

But that was when I was in my own multiverse.

Now I'm being held hostage by this horrifying octopus thing that's apparently me, and he's waiting for his version of Dream to come and rescue me because he thinks that it's some clever trick.

At first, Goopy decided that he'd keep me with him. By which I mean he held me three feet in the fricken air with his tentacles. Upside down.

Thankfully he finally put me in the dungeon, and I found a random notebook. I'm hoping that my friends find me and bring me back, but if they don't get here in time I want them to know what happened to me.

I guess it could be worse. There could be an angsty version of Cross and a crazy version of Error.

Day two:

Surprisingly, there is an angsty version of Cross and a crazy version of Error.

In fact, Cross and Error here are both insane. Everyone in this creepy-ass castle is insane, actually. At least Cross seems chill, despite being angsty. And he brings me food.

...I just heard Angsty Cross and Goopy talking and Cross called Goopy 'Senpai'. My relationship with Cross from my multiverse is being put into a new perspective.

This cell is so small. I honestly prefer the ones in JR, which is saying a lot because my being in a cell in JR usually means I'm very close to death, or whatever my bro has planned for me.

I can feel the despair in this place, too. I'm only one in many people imprisoned here, and most of them have gone insane. I can also sense that Goopy imbued the walls with his own negative aura, which is a lot stronger than mine. Probably because it makes the prisoners even more hopeless.

Well, joke's on him.

I'm already insane.

Day three:

Okay. Someone's here. I can hear fighting, and like every ten minutes there's a surge of positive energy that cuts off almost immediately.

...It can't be my Dream, can it?

Goopy obviously are the apples in this multiverse. That much is obvious. Which means that his Dream can't have a very powerful aura, but, my brother's POSITIVE aura is just as powerful as Goopy's. So in theory, their auras would periodically cancel the other's out as they weaken each other.

The more I think about it, the stupider that idea is. It's most likely this multiverse's Dream. He probably has a weapon like my spear, only he can't use it all the time. Maybe a long-range weapon like a bow or ninja stars.

Hey, why don't I have ninja stars?!?

Day four—Cross:

Sooo I'm here now. Nightmare pretty much crushed me in a hug when I got here, so I guess he's happy to see me.

Speaking of nightmares, the bipedal octopus may or may not be thinking up ways to violently murder me. Because I showed up at the same time as these "Star Sanses." I didn't even see them, so I have no idea why he thinks I'm involved.

Nightmare says the bipedal octopus is an alternative version of him. How did Nightmare turn into THAT thing?!?

Ugh. I don't want to think about it. I'm going to take a nap on the luxurious bed of nails. At least, it feels like sleeping on a bed of nails.

Nightmare:

Are lobsters like mermaids to scorpions? Wait. Can lobsters breathe air? Because if so then they're definitely mer-scorpions.

Side note, I need to come up with a nickname for Angsty Cross. I mean, I guess I could call him Scarfs since he always has his scarf over his face.

Or maybe I could call him Ink Jr. since he acts like Ink back home. Cross seems to agree with me. I think I'll use both on him and see which bothers him most.

Day five—Nightmare:

Remember how I said I was going to die? I was only 90% certain then. Now I'm 99% certain.

Angry Error decided to drop by. I'd like to mention that before, when I said he was insane, I was only relaying information that I had heard. I hadn't actually met the guy. Turns out he's a much angrier, much more unstable, and much more destructive version of Blue.

And when I say destructive I mean he destroys AUs for fun. I'm going to call him Dr. Destructo.

I really hope our Error doesn't meet Dr. Destructo. He probably won't take it well. On the other hand, Dr. Destructo seemed pretty miffed that Cross and I exist, so maybe he'll die of shock when he encounters Error.

Cross:

This place is awful. The bed is uncomfortable, the food tastes weird, and there's nothing to DO. At least my cell is next to Nightmare's. Yes, he hugged me through the bars. That's not weird; you're weird.

I also feel like I'm never going to get out of here, even though it's only my second day. If I didn't know Nightmare, I wouldn't recognize it as the same magic he has. Still, it's really discouraging. I'm sure we'll get out somehow.

...Still working on the how part, but even when I get to it I'm not going to write it down. I'm not stupid, I know that Goopy and his goons can just take the notebook and read it.

Side note, Nightmare are you fricken serious. Of course lobsters are mermaid scorpions, you dumbass.

Nightmare:

Says the guy who tried to buy a $30 cactus online.

Bleh.

Cross:

That's not a valid argument, dude.

Nightmare:

Of course it is. Also, we are we having this conversation on the notebook? Its like texting while we're sitting next to each other.

Cross:

🤔 🤷‍♂️

Nightmare:

Dork.

Day six—Cross:

I have decided that I am going to be a troll.

Prepare yourselves, villains! Cross, Second In Memes, is about to make your lives living hell. Eventually they'll have to let us go.

There's a line that's been erased, but you can just make out what it says.

Or just me, but I'm pretty sure Error got here too so I can find him and we can bust Nightmare out.

Yeah, that'll work. Totally.

Or maybe I could summon Kevin. He'd frickin murder these b****es.

Nightmare:

Cross, Kevin isn't a weapon of mass destruction, no matter how violently he likes to greet us. Also, please don't encourage Goopy to turn him into chicken nuggets.

If Goopy kills Kevin, it's entirely your fault and I will not stop his angry ghost from using you as a chicken scratching post.

Cross:

But Kevin's, like, immortal. I doubt Goopy could kill him.

Nightmare:

Yeah, and so am I. And Dream. But we can still be killed.

Cross:

Oh. Right.

...I'm hungry for chicken now.

Nightmare:

You sicken me.

I might do some more of this later, but eh. Whatever. Just wanted to write something, made it too long, then deleted some of it.
