Author's Notes:

Now remember, this will be the evil Sunset, given the placement of it.

Sunset Shimmer emerged from the other side of the portal. She found herself in front of a school called Canterlot High. Whatever this world was, she'd make do with taking it over until 30 moons later, when she could return and maybe have a better chance at taking the greater power she sought.

She started walking on all fours, until she saw some strange-looking creatures the likes of which she had never seen before. They were as colorful as ponies, but walked on two legs and had hands similar to dragons, but with much shorter claws.

"What in Equestria are you?" Sunset asked a female of these creatures, not trying to not sound weirded out.

"Um... I'm a human, just like you," said the girl, equally weirded out.

"Huh?" Sunset looked at her hooves. Or rather, what used to be her hooves. They had been replaced with hands. Sunset ran over to the window of a nearby building and looked at her reflection. She had transformed into one of these creatures. She screamed at the top of her lungs.

She then recovered. So what if she was one of these human things now? She could adjust to this and take over this world, then return and take over Equestria 30 moons later. First she had to get familiar with this world.

Once she found her own place, the school she had arrived in front of would be a good start. She'd become the most popular girl in school. And also the school bully, it would make her feel even more powerful. She considered getting rid of the magical book Celestia had given her, but deep down a part of her thought she'd want it in the future, so she kept it.

As Sunset walked down the sidewalk, she noticed she got weird looks from people passing by. She got the feeling humans didn't usually walk on all fours. So she stood up and started walking on two feet, having difficulty keeping her balance.

As she started to get the hang of walking, she realized she needed to pee. She ran around town in search of a bathroom. They didn't have any outhouses around, it seemed, but maybe some of the shops in this world had them. Unless humans simply didn't pee. This was a nasty thought, but then, if this was the case, then she wouldn't be in need of a bathroom herself.

Sunset eventually found a small building that resembled a shop, and ran inside just as someone else was coming out. She ran up to the cashier. "Where are your bathrooms?" she asked, holding herself.

"Right that way," said the cashier, pointing.

Sunset immediately ran towards the bathroom, but slammed into the door and fell on her butt. She got to her feet, rubbing her butt, then felt her head. She no longer had a horn, and so she couldn't magically open doors anymore. This was going to be inconvenient. Holding herself with one hand, she fumbled with the doorknob with her other hand until she finally opened it. She closed the door, locked it with a bit of difficulty, then saw the toilet right in front of her. At least some things stayed the same in this world.

She lifted her orange skirt, sat on the toilet, and sighed in relief as she started to pee. It certainly would have damaged her powerful reputation before she even gained it to wet herself on her first day here.

But something was wrong. Though Sunset's skirt was out of the line of fire, she was feeling a warm wetness anyway. One she had never felt while peeing as a pony. She lifted her skirt and gasped.

She was wearing an unfamiliar article of clothing under her skirt. It was black, and only covered her crotch and butt, so it was less than shorts. And right now it was glistening with wetness as she peed. Sunset blushed beet red. She was peeing herself. She was wetting whatever this part of her outfit was. She sighed in dismay as she continued to pee through her underwear into the toilet.

Once she finished, she stood up and let her skirt back down. It at least seemed to hide the wetness. If she wanted to take over this world she'd have to understand it, including what this soaking wet part of her outfit was. She flushed the toilet and walked out of the bathroom, hoping no one would notice a pee smell.

She had to stay in her wet panties, as she would later learn they were called, until they dried. And she had another accident in them on her second trip to the bathroom, trying to pull them down with her hands, which she was still not used to yet, in which she ended up making a puddle on the floor, much to her embarrassment. She didn't care who would have to put up with it or clean it as long as they didn't know it was her, though she was certain the cashier of this convenience store noticed her wet footprints as she walked out. But the third time, she made it.

Of course, even after they dried, her panties still smelled like pee, until she was able to make enough money to get her own place, a washing machine, and new sets of clothes, including a cute pair of purple pajamas, though she still wore this outfit most of the time. It wasn't long before she enrolled in Canterlot High and took it over, quickly getting a hang of how this world worked. As the popular mean girl, she got two henchmen, a boyfriend, and even drove five friends apart.

After Sunset returned to Equestria and tried to steal the crown of Princess Twilight Sparkle, Celestia's next pupil, and Twilight followed her to the human world, Sunset was sure she had gone through the same pee accidents as her. But she chose not to taunt her about it or include it on her embarrassing video, as Twilight would no doubt put together that Sunset had wet her panties as well, and if it ever got out, Sunset would be utterly humiliated so close to her goal.
