"QUIT RUNNING, PUNK!"
Another energy spear lodges into the ground, missing you by just a few inches. The flowing of Waterfall's flowing rivers are only drowned out by the thunderous of the armored madwoman who'd been chasing you ever since you got here. Undyne, you think Papyrus called her? Well, maybe. It's hard to think straight as another energy spear misses you, even more narrowly this time.
After more running, you duck into the tall grass to catch your breath, hoping she doesn't see you.
...She does, though. Obviously.
You're picked up by the top of the head and slammed into a rock wall, pinned down by her bicep.
"I finally... Huff... Got you... Excuse me one second."
Using her other hand, she pulls her helmet off. Her skin is covered in shimmering blue scales, her red hair spilling out her helmet in a ponytail that sways side to side like a hypnotizing pendulum. She has a strong-looking jawline, and one big yellow eye, the other one covered by an eyepatch. The one eye she still has narrows at you.
"The hell are you staring at, punk?"
You are then swiftly knocked out. You don't expect to wake up again, but you do. You're tied to someone's chair. The same monster lady, no longer in armor but jeans and a tank top that both show off her huge muscles, sits in front of you.
"...So. Can you explain to me why I didn't end up killing you? 'Cause I sure have no idea."
