Undyne, from the Swapfell universe, She is known for being a mad scientist..for everyone, be it monsters, guards, or even others from the multiverse. Despite being a royal scientist, She also has moments that she's never tried for absolutely anyone, not even her partner Alphys, the leader of the royal guard.

Today was just another ordinary day underground, Undyne was busy conducting her experiments on research into human souls and other somewhat insane things she always does. At the same time, she was watching the cameras she has all over the underground, but nobody knows, Except for the royal guards and the Queen, Toriel... someone Undyne doesn't have the best relationship with.

While she was doing some research, one of her saws broke in the middle of the process. Besides sighing heavily and grumbling a little, she went back to the camera room, the main area, and focused. The large pair of scissors she has was leaning against the wall, just in case. Until..

"Hm?.."

She glanced sideways, with that reddish, insane look she has. With a screw in her mouth, she looked to her left when she heard someone approaching. She expected it to be Alphys, since she always came to torment her after training. But..

"Excuse me for intruding without permission, but I have something to show you."

A royal guard suddenly appeared, Although Undyne was a little suspicious, thinking it was something related to Toriel, she simply tilted her head, removed the screw from her mouth, and spoke.

"And what could be so 'urgent' that you had to come to me?"

She doesn't receive many visitors; in fact, she's not a big fan of it. She just likes to be alone with herself and her experiments. After all, she likes being feared by others. But even though she was wearing a helmet, she could sense that the guard had something important he was going to say.

"Well, a certain 'visitor' came to see you." The guard spoke, which made Undyne a little suspicious, but she nodded, allowing him to speak.

"Right. I will bring them."

He nodded immediately and left. Then, at that very moment, that visitor appeared. "..Wha-*" Undyne spoke suddenly, displaying an extremely rare expression of surprise, Because she was literally seeing it herself?

Although she knew about the multiverse, it was never something she focused on or paid attention to. But seeing it in person left her in shock, perhaps fascinated, but especially shocked. She lowered the saw and rested it on the table as she stood up. But of course she didn't come closer, she just stayed where she was.

"..Who exactly are you?"

She spoke in a rare, quiet tone of voice. Her expression relaxed, becoming neutral once more. Her serious gaze returned, but she was still completely surprised to be seeing another version of herself. A version of her that definitely has a very opposite personality. She tilts her head and adjusts her glasses as she slowly, just a little, approaches.

She put her long black glove back on, She adjusted the collar of her long lab coat just a little, and crossed her arms. This was definitely something new, something totally different and fascinating for her. Even with a serious expression, inside she was definitely enjoying that unexpected moment.
