The House of Undertale AUs

Chapter 17

Y/N's POV:

Gaster finally gave me another gift that he made. Well, actually, I made it but I wasn't controlling my own body. It was a bunch of random rings with a label on top. I saw "UF" and "US" and a whole bunch more.

"Ink told me what other AUs are coming but it's not accurate," Gaster told me. "At least you'll be able to do reconnaissance now."

"Wait wait wait, how do these help me?" I asked.

"When you put on a ring that says, for example, UF, then, you'll fit in with your surroundings and what people usually were. Try it," Gaster urged me.

I sighed and picked up the UF ring. Then, I slipped it onto my pointer finger. Immediately, I was wearing a black coat as usual whenever I because Gaster!Y/N but this time, the jacket was unbuttoned and I had a red t-shirt inside. I also had an annoyingly itchy red scarf, with dark red pants and black boots. With the help of the mirror on the wall, I saw that I had red glowing eyes.

"I like it. But, the scarf sucks," I commented. Although I didn't really need it, the rings help me blend in at least. "So, now what?"

"We need to wait for Ink. He'll take us to the next AU," Gaster replied. "Apparently, it's called 'Underswap'. You should have all the information about it on your tablet."

"Yea, I know. I already read it. It's so confusing though. Like Sans and Papyrus swapped so Papyrus acts more like Sans and Sans acts more like Papyrus." I shook my head. "It's really confusing."

"You'll be fine," Gaster promised. Then, Ink appeared.

"Ready to go?" he asked, and then looked at me. "What are you wearing?"

I looked down in surprise. I was still wearing the UF clothes. "Oops. Right." I took off the ring and my clothes went back to my normal one. "Sorry. I forgot about the ring."

"Is that for UF?" Ink asked. I nodded. "I don't think you'll be needing it, but who cares. Where's the ring for Underswap?"

I looked at the box full with rings. There were rings labeled DT, MT, and a bunch more. I finally saw the ring labeled US for Underswap. I was about to put it on, but then stopped myself.

"Who are you in Underswap?" I asked Gaster. He thought about it for a moment.

"To be honest, I'm not sure," he confessed. I groaned and looked at Ink.

"Who's Gaster in Underswap?" I asked.

"Didn't the tablet tell you?" He replied back. I thought for a moment and then whipped out my tablet. I scrolled down and the looked carefully.

1 Frisk has been swapped with Chara

2 Sans has been swapped with Papyrus

4 Alphys has been swapped with Undyne

5 Toriel has been swapped with Asgore

6 Mettaton is swapped with Napstablook

7 Flowey has been swapped with Temmie

8 Aaron has been swapped with Shyren

The swapping section for Underswap stopped there.

"Nope. Nothing about who Gaster is," I replied to Ink's question.

Ink frowned. "That's strange. To my knowledge, I don't think Gaster ever swapped with anyone (to be honest, u don't even know if he ever swapped with anyone of the characters, and I've been on my electronics for the past half hour trying to see who Gaster is in Underswap. I got nothing)."
