TBH I hate the UNDERTALE fanbase forcefully invaded the MOTHER fanbase, but I couldn't resist temptations. I do not support Game Theory association with the relations of these games in any way.

Chapter One: Osohe Strange

It had been several months since the Dark Dragon had reset the world under the influence of the twelve year old heroine, Lucas. He, along with his friends Kumatora and Duster, and his loyal dog Boney, had defeated (technically) King Porky. It was a grueling task, set up against a mad man with no sense of age, reason, or sanity. After Lucas had pulled the final needle of the Magypsy Locria, his heart of love mixed with a heart of destruction and nothingness, it had seemed there was no hope for the rest of the habitable Earth.

But there was.

Yes, there was destruction. For many, their lives, mostly animal, some human, were cut short. Despite this, the world prospered. Tazmily was restored to its normal state, even if that normal state included everyone's memories being tainted. Now, Lucas lived back at home, with regular visits with Kumatora and Duster. Not that it truly mattered, for a kid to have an older teenage friend and an adult friend, the situation was a little strange. And yet, everybody understood, and everybody was grateful.

Lucas stood by Boney's doghouse, and was petting the dog in question. Kumatora was there as well, showing off a target-less PK Starstorm to show how her skills with it had improved. Duster was watching her with interest, possibly dreaming about what special PSI technique he would have. After yet another PP exhausting blast, Kumatora turned around.

"What'dya think? I know I won't need to use it anytime soon, but…" Kumatora threw two punches into the air, "Gotta stay sharp! Can't get stale in my moves!"

Lucas absentmindedly clapped for Kumatora. Duster looked at the boy.

"What's up, Lucas?" he asked. "Even though you used to be quiet, you seem a little… out of it."

Lucas looked down at Boney, then back up at Duster. Boney whimpered. "I just… Boney has been communicating with me through telepathy," Lucas whispered, and Kumatora stopped her showing off, "dogs can sense things humans can't, and Boney has been sensing something strange…"

Kumatora paused. "I can understand animals too, but not unless I wanna," Kumatora noted, "I can understand what he's saying now..." Kumatora closed her eyes and focused.

"(I feel a great presence nearby…)" Boney whined, "(By Osohe Castle!)" Boney sat up and barked. Lucas repeated the information to Duster, who nodded.

It seemed like their journey would never truly be over!

The three people and dog trekked to Osohe Castle. Boney suddenly stopped and ran off towards the direction of the graves near where Lucas had found the note from the Mr. Saturns. Lucas, Kumatora, and Duster ran off towards where Boney had run to. To their surprise, there was a huge crater, possibly miles deep, in the ground. Where had it come from? Was it left over from the rebirth and destruction?

Boney whined and looked down at the hole. Was he…? He was. In mutual understanding, Lucas deeply concentrated on his PSI powers. Maybe he should have done what Kumatora had been doing and trained himself even after all of the events caused.

"PSI Shield Omega!" Lucas shouted, and a physical barrier was placed around the party. Duster looked at Lucas with hesitation.

"Lucas, are you sure we should just jump down this gorge?" Duster asked reasonably. "There might be no escape down there, and if we were to seriously injure ourselves, no one would know…"

"Oh Duster, you're always the reasonable one," Kumatora grunted, "and always the no-fun police too. Lighten up, will you? If we get lost, I can shoot us upwards with PK Thunder Omega."

Lucas frowned. Being shot with a powerful PK Thunder seemed less than desirable. This stubborn explanation seemed enough for Duster. He must have given in, as once Kumatora had an idea, there was no stopping it.

Lucas, Duster, and Kumatora joined hands, with Boney grabbing on to Lucas's pant leg. At the count of three, the group jumped down into the abyss. It was a horrible reminder of falling down the "elevator" Porky made for them to get underneath New Pork City. The pressure of falling was too great, and the four friends lost grip of each other…

The group soon found out that they had an unusually soft landing.

Lucas got up, his PSI Shield shattered. He had actually landed on Kumatora, which was probably why his land was a little less hard. But Duster and Boney seemed to be safe on the soft, yellow flowers on the ground underneath them; Kumatora, not so much.

"Get off me, Lucas!" Kumatora snapped, rolling over so that Lucas was flung off. She stood up and dusted herself off, grumbling about how Lucas 'almost broke her spine' and the like. Boney and Duster got up as well. The leftover sunlight from the world up above must have promoted the growth of the flowers down below.

Boney sniffed the air, searching for any unusual scents. His tail suddenly straightened, and he bounded off yelping towards what seemed like a formed door.

"You seriously need to train him not to run off randomly!" Duster remarked, and then ran as best as he could towards the entrance. Lucas followed, along with Kumatora, still mumbling, though Lucas was sure she was just playing around by now.

Boney let out a single bark. "(Look!)" The dog told. In front of the foursome was a flower. It was bigger than a normal one, and it looked a little bit like the ones they had landed on. It had a face, and it looked a little shocked when it saw four creatures standing by.

"Why, howdy!" the flower spoke, much to the surprise of Lucas and friends. Was this a leftover chimera? "I'm Flowey. Flowey the Flower! Hmm, I see you four are new to the underground, aren't you? Well, I might as well show you how things work!"

"Look here, Planty! We don't need a little tutorial of whatever is going on here!" Kumatora growled. Flowey shot her a malicious look, and then got the party into a battle. However, instead of a normal fighting sequence, four heart shapes appearing in front of them.

Lucas looked shocked. His heart was colored red, and moved when he did. Duster's was green, with a little shield in front of it, Kumatora's was yellow, and Boney's was orange. Kumatora narrowed her eyes and tried to touch the heart, only to reel back and shiver from it. The girl then looked at Boney, blush on her face, like after sitting on the chairs in the flying limousine.

"That's your SOUL," Flowey cheerfully explained, "It's the culmination of your being! SOULs get stronger by gaining LOVE." Flowey winked. Lucas looked disturbed. Was this based on his special PSI power?

"LOVE is spread through little white 'friendliness pellets…'" Flowey droned. Duster cringed. "With enough of those, your LOVE increases, and…" Flowey looked at the group, seeming to stare into them. Suddenly, his face went a little bit horrified.

"How are their LVs well past 60? D-did they…" Flowey whispered. His face went back to normal. "I-I see how you guys are. I'll help you get stronger, then!" Without warning, Flowey sent out a ring of unavoidable bullets.

Lucas and company didn't have much of a choice against the bullets, since they didn't know the full capability of their Soul-Powers, so they hid behind Duster, who had the shield. Boney barked as the ring got closer, and the shield couldn't defend from all sides. Lucas couldn't take the pressure.

"PK Flash!" Lucas yelled, and a bright light emitted from his fingers to the air. Duster, Kumatora, and Boney closed their eyes, while Flowey was caught in the blast of light. Flowey screeched and dug back into the ground, disappearing. The fight was over, and the four hearts evaporated.

Lucas knelt down near where Flowey used to be rooted. "I can't see it in there," he reported, "the little flower got away."

Duster shook out his leg. "I don't know what the deal is down in this place, but it's so much different than Tazmily." He got a quizzical look on his face. "It's almost like we're in another world."

"I don't care what 'other world' we're in, I just want to go back now." Kumatora tried to pull her over-sized sweater lower down her legs. "It's cold down here, too!"

Boney barked. "(Well, maybe if you wore more clothes you wouldn't be-)" Boney's words were cut off by a snarl. "(Someone's here!)"

Duster heard the footsteps right after Boney protectively stepped out in front of Lucas and Kumatora, with Boney by his side.

"Hello? Is anyone there?" A voice, soft and feminine, called out from deeper in the cave. "I saw a great big flash of light, is anyone hurt?"

As the voice got closer and closer, a figure stepped out. She had white fur, soft, red eyes, and small horns like a goat. She had floppy ears, and wore a dress with ancient symbols on it. She was tall and broad shaped.

"Oh my!" the goat woman gasped, "Four people, all at once! You poor things. Are you injured?" She went up to the group and Lucas in particular. Lucas flinched away and felt the urge to summon another PK Flash at this strange creature. Boney growled defensibly.

"O-oh! I suppose I am rather shocking, yes?" the lady chuckled. "My name is Toriel, the guardian of these ruins. I am a race called a monster, and have lived underground for as long as I can remember. Please, do not fear me, I bring no harm.'

This Toriel asked the group to follow her. Duster warily looked at her before trying to get the rest of the group going. Lucas wished desperately he hadn't taken off all of his valuable armor. Only Boney and Kumatora had equipped things now, with a red collar and Mystical Gloves.

Kumatora leaned in to whisper in Lucas's ear. "See," she hissed, "I knew I was right practicing my techniques. These monsters or normal-ish chimeras are down here!"

Lucas gulped as he set out into the caves with a strange creature and friends who wouldn't leave his side.

I am so clever making a new story in relatively short doses that is easy to write! Mwahaha! The reasons for the SOUL colors are these:

Lucas is the leader of the party, so he can run from battles

Kumatora's normal bash attack says "shoot" for some reason if I'm not mistaken.

Duster's shield is more like him using his bad leg to block, though not really. Plus, I've always seen him as the mother-ish type to the group, wanting to protect them.

Boney gets orange because he is the fastest and it would be easy to dodge attacks with that speed.

Yes, Boney could have dodged Flowey's bullets that way, but he's a dog, and they don't know the true powers yet.

R&R,
