Legacy- Part 1

W.D Gaster was an elusive man. Not too many people knew anything about him. A lab rat, hermit and shut in without much to speak of. The people that claim to know W.D. Gaster, do not know Wing D. Gaster- before the accident. In 198x, the project that Wing Gaster was working on, went terribly wrong and had lasting effects, hidden from the monster community.

"Come on little brother!" Papyrus yelled rushing ahead of his mother and young brother. Sans was pulling his mother's hand, excited to catch up with his brother.

"Calm down you two, we don't even know if your father is done yet. We can't go into that part of the lab, you know that." Verdana warned her children. Her husband Wing, was fairly new to the Royal labs in the Underworld Human Defense Division. All that she knew was that the work was confidential and dangerous. Regardless of her internal warning signs, Wing promised the part of the lab that they were meeting in for lunch was safe. She looked down at her little boy, skipping at her feet and smiled to herself. She picked up Sans, "Sans, it's a beautiful day, the birds are chirping, the sun is shining, and children like you…" She paused to let her child finish.

"Should be listening to their mothers." Sans finished with a small pout.

"That's my boy."

The trio entered the lab doors, greeted by a small yellow monster. Behind the receptionist's desk, another small yellow monster peaked out, before quickly dashing back under the desk. "Hello? Ca- Can I help y-you?"

"I am looking for Dr. Gaster's lab?" Papyrus tugged at the bottom of his mom's shirt.

"We are going to see dad now?" The receptionist smiled at Papyrus.

"Your dad's lab-b is on the s-second floor. 201." As the trio walks away, Verdana gave the receptionist a look of thanks. Walking to the lab, Pap was in a near skip, singing the numbers of the rooms they pass. As they approached the door 201, Papyrus ran up, and burst through the door.

"DAD. WE BROUGHT SPAGHETTI" In the doorway Papyrus holds the large lunch bag high and proud, ignoring the laughter of the other workers in the lab. Gaster turned the corner to see his family waiting for him. He smiled to himself before greeting his son and patting his head and taking their lunch.

"Hi Hon." Gaster leaned forward to kiss his wife. "Gee Sans, you feeling alright, you are looking kind of boney there, champ!" There was a collective groan from the monsters in the lab.

Sans lit up with laughter. "That was a good one dad!" Gaster led his family over to a comfortable area next to the doors to eat.

"This is a nice set up Wing. Asgore is really taking good care of this unit isn't he?" Verdana said as she took in her surroundings. The lab was new and most of the equipment still had an intense metallic shine. There were big windows on the opposite wall, displaying a huge machine in the secure room.

"Ya, with the funding from the crown, we have made rapid progress with this project. The applications extend way beyond weaponry." Gaster looked down to sans, sitting on the floor listening intently. "Want to know what I call it?" Sans nodded excitedly. Gaster picked up his son and twirled "I call it, The GASTER BLASTER!" Sans giggled with joy as they walked to the window.

"It's so cool dad!" Sans put a boney hand on the window and gazed at the huge machine. Soon, Pap and Verdana were also at his side.

"Why the huge machine if you are trying to arm monsters?" Verdana asked.

"We have to condense the energy into ammo canisters to go into the blasters. We are actually just about to run a test, see how much energy we can put into one cartridge."

"I want to see that dad! Can I stay to see it? Please!" Sans begged. Wing and Verdana exchanged looks.

"I don't see why not." Wing put down Sans before entering into the secured area to start the test. She was happy to see her husband in such a respectable position, inventing groundbreaking work for monster kind. She watched through the window as her husband worked. He turned to her from a lower platform and gave her a thumbs up. The machine behind him whirred and glowed blue and white, pulsing downward to the bottom.

The pulsing got faster and the workers moved faster. Something wasn't right. Verdana took inventory of her children. One Sans, by her side and one Papyrus, not in sight. "Where is Papyrus?!" She panicked.

"Down there mommy." Sans pointed at the window, Papyrus was down on the platform near his dad, watching.

"Why didn't you say anything Sans!" Verdana yelled.

"He said he wanted to help capture humans! And then went down there." Sans looked confused. Verdana scooped up Sans and ran to the door. The machine seemed to become more unstable. She slammed it open and yelled down. "WING! PAPYRUS!" Wing turned around to see his son mesmerized by the rapidly pulsating machine and his wife and youngest running down the stairs to him. The needles on the machines were out of control and the other monsters in the lab were attempting to contain the failing machine.

"There is no time! Everybody get out!" yelled another monster. Wing rushed to Papyrus. Verdana and Sans were already on the same level as the machine. Monsters were running everywhere as the machine began to crack. A burst of energy came out of the machine and Verdana grabbed Sans and pulled him in close to her, shielding him in a ball. A passing intern jumped on Papyrus and Wing as another burst came from the machine. More and more energy blasts came until the whole machine collapsed.

Wing woke up, Pap in his arms, still intact with only a few cuts. He looked around his lab. Most of the invention was in rubble and on fire. Most of the workers seemed to still be on the floor, injured but there was a significant absence in some of his employees. Wing scanned the room, looking for Verdana and Sans. All he could see was fire.

"Dr. Gaster! Over here." A monster yelled to him. One of the less injured monsters came over to watch Pap. Wing did his best to crawl over to where the monster had called him. He was clearly severely injured, but he could not determine the extent. Gaster approached a monster knelling near a small blue flame. As he got closer, he could see that the flame was… Sans. Wing stumbled faster to his son and held him in his arms.

"Sans?" Wing could barely get a word out. Sans didn't move. Wing clutched his son closer to him and he began to cry. The monster laid a hand on Gaster's back, consoling him.

"Da-d" the small voice came from his arms. The rest of the flames seemed to have subsided.

Sans had opened his eyes, seeming void of life, except for the blue flame coming from his right eye.

"Sans." Gaster hugged his son, relieved. Two sons, fairly unharmed, but there was no sign of Verdana.
