Escaping the freezing cold of Snowdin Town, the scenery drastically changed from snow and trees to a straight rocky path and a river, flowing silently next to it. Two monster children, both looking very similar to each other with their slim body and yellow skin, were casually making their way from their snowing hometown to the famous Waterfall area, while seemingly arguing.

"I agreed to tag along, because I wanted to get out of the snowstorm, not to help you look for the all-so-great heroine!" the glasses wearing girl complained at her younger brother.

"But sis, don't you know freaking cool she is?!" The striped shirt wearing boy quickly retorted, his eyes firmly beaming with excitement.

However his sister had already stopped listening and instead curiously eyed the turquoise echo flower, the two were passing, before turning back to him.

"Not really and quite frankly, I don't care. The way, people like you worship her as a heroine for no real reason seems completely ridiculous to me" She coldly exclaimed and would have probably crossed her arms, if she had the fitting limbs for that.

The boy was dumbfounded by this for quite a while. How could anyone say something like this about the great and amazing Undyne? It just didn't make sense to the young boy and the shock made him abruptly stopped walking for a moment, before he shook his head and ran to catch up with his sister.

"Yo sis, you can't say that! She will save us all, don't you know?"

The girl however just sighed in disbelief and marched on, enjoying the beautiful scenery of all the cyan lakes, flowing through the area, as they gave a mysterious, yet beautiful vibe. How can the sight of a random wanna-be savier be any better than this? She never understood her little brother, but this was especially confusing to her, to the point, where she was ready to continue the argument.

"Fine. Tell me what makes her so amazing. Tell me why she's considered a heroine. It can't be just because, she's powerful can it?" she questioned with a raised eyebrow.

"Erm...haha, obviously it's because she saved us all, don't you remember the story?" He nervously grinned, while slightly sweat-dropping.

His sister chuckled "You certainly don't"

"Actually the whippersnapper isn't that far off" A sudden third, elderly voiced echoed from out of nowhere.

The siblings both immediately tensed up and looked around, to see where the voice was coming from, which was extremely hard, since the echo flowers kept echoing the voice. Loud and slow footsteps however gave away the position of the approaching…

"Old turtle guy!" The boy shouted.

"It's Gerson, come on kid!" The monster annoyingly retorted back, before clearing his throat.

From his clothes, someone would say he's an archaeologist, but it was fairly common, that he was running a shop in waterfall, though some even used to tell, that he was once a well known hero. It was kinda hard to keep track, but he was definitely a turtle.

"Wait? Sir, what do you mean, my brother wasn't that far off?" The girl asked with a tilted head.

"Well the story goes back many years ago, when Undyne was merely a child like you two. Wait….I don't remember it anymore..."

"Aw come on!" The siblings yelled in sync.

"Alright, alright, I'll try to remember! Jeez such rude kids these day..." Gerson stayed quiet for awhile and tried to recall the events from so many years ago, while the two kids both sat on the ground, knowing this was gonna take it's time.

"Hmm….yes I think I remember. Undyne was a very active and energetic girl. She would go or climb to the places, that others wouldn't even dream of. Wha ha ha I remember that one time…

On her toes, the red haired girl slowly sneaked away from her house and turned around the corner, before looking behind her to check if anyone saw her. She smirked widely, when she was, that she was alone and started sprinting.

Besides her long hair, that was like always tied to a ponytail, Undyne had very simple clothes in form of a black tank top, bright brown pants and muddy black boots.

The day before, she had heard rumors about several bandits, that have been stealing treasures and valuables from the local people in Waterfall. Because of it, most of the parents forced their children to stay in their houses, since it'd be dangerous to go outside and Undyne was no exception. But that wouldn't stop her.

This was finally HER chance to become the heroine, she always wanted to be. The scene already played itself out in her head. She would make an epic entrance and challenge the bandits to a fight, while summoning a spear in her hand. She would then single-handedly kick their asses to a pulp and be celebrated by every monster in the underground.

"Watch out, all you evil-doers! Undyne is on her way to serve justice!" She proudly shouted out in the darkness, before finally taking a stop.

She must have ran for longer than she thought, as the girl already find herself around the many ancient texts on the wall, with smaller waterfalls and of course echo flowers, decorating the whole area. Pondering where a bandit would hide themselves, Undyne stood under one of the waterfalls and showered herself. For some reason, she could always think better, when surrounded by water, even if "Better" still didn't make up for what she already lacked in critical thinking.

Hmm...if I am a bandit, where would I be...I would probably go steal something, but where would be a good place to steal something? She thought deeply, putting a hand on her chin.

"Oh! I got it!" She suddenly exclaimed and ran off once more.

This time she put her focus on the path in front of her and soon approached a dirty pond, which she jumped right into and started swimming. Even though Undyne had never asked, what kind of monster race she was, her relation to water was obvious from the first moment, she set foot on a puddle. So what would have taken other monsters several minutes, took her only a few seconds.

Quickly reaching the small cliff at the end of the other side, Undyne summoned a spear and rammed it into the wall. This helped the girl lift herself up and with a big push, she gripped her hand on the rocky edge. After dozens grunts and sweat drops, she finally pushed one of her legs up as well and with one last roll to the side, Undyne was lying there on the ground, taking a few deep breaths, before standing up, always keeping that determined spark in her eyes.

Before her were a couple of round houses with all their different colours and gardens. Undyne chuckled at her own genius and looked around for something to hide herself behind, so she could lurk for any bandits.

Of course a thief would try to steal something in a house, but not on Undyne's watch! And so the waiting game began.

But Undyne absolutely despised the waiting game. Patience was never her strong suit and so she ended up, twitching with her right eye, stomping the ground with her feet and even trying to balance a spear with her finger just for the heck of it.

Awhile passed.

"Have...to...stay….awake.." She mumbled under her breath, having a hard time actually keeping her eyes open, as her head was already leaning against the boulder like a pillow.

When suddenly Undyne finally noticed a movement from the corner of her eye. She abruptly stood up and jumped over the boulder, a spear ready in her hand. And indeed the movement came from a tall, suspicious looking monster with yellow skin and a weird looking hat with little bumps sticking out of it. However what really caught Undyne's attention was the giant bag he carried over his shoulder. This must have been all the treasures he stole, this person was one of the bandits!

"Hey stop right where you are, you thief!" The yellow monster turned surprised around to face the child, but quickly looked back behind him to see, if she didn't mean anyone else.

"I'm talking to you alright! The days of stealing and evil are now finally over! Justice will be served!" Without giving the "thief" any time to respond, Undyne lunched into him and kicked the monster right into his guts. Not stopping there, she grabbed his arm and threw him towards the ground.

She was about to throw a barrage of spears at the guy, when she suddenly felt a grip on her hand and her tiny body was without any warning lifted from the ground.

"Dammit Undyne not again. That's the mailman, you're attacking!" The figure sternly told her and swiftly threw the girl several feet behind him.

Undyne was unprepared and landed, faceplanting the ground. Enraged she pulled herself up and turned her head to see the figure was actually...
