[Undertale Contest Entry] AN ECHO FROM THE PAST

✌☠ ☹☜✌☼☠ ✌ ☹☜⚐☠

Chara leans against the door of the machine, flipping her knife in her hand. Sans cringes, seeing Frisk's desperate attempts to make Chara leave, but to no avail. He looks at her, blue light pulsing from his eyes stronger then it ever has before. He thought of Frisk, Papyrus, Alphys, Undyne, Snowdrake, Jerry, everybody...dead. "Let. Her. Go." He says, the light in his eye growing so strong he has to close it. 

"Oh, Sansy, I only have two more souls I need before I can erase this world." She murmurs, holding up her hand. A pink soul. A yellow soul. An orange soul. They all revolve around her hand. The room fills up with silence, the only noise being Neon's angry pounding on the door and her muffled cries. "I saved the best souls for last." Chara stands up and presses the green button of the machine.

"NO!" Sans screams and slams Chara into the ceiling, running over. Chara's knife is flung down at him, and he crashes into the wall trying to dodge it. Neon's furious and begging wails fill the room, propelling Sans even faster. He sees her essence being practically reversed on itself, creating a shadow. An echo of what she was. Chara snarls, tackling Sans onto the ground.

"I will not let you ruin my plans, you SMILEY TRASHBAG!" She screams, searching for her knife while Sans repeatedly shoots bones at her, his eye creating a flame worthy of challenging the sun. Chara hisses and turns away, her eyes scathing from the light. The DT Machine starts whirring and clanking as it works harder to contain what's left of Neon. Sans kicks Chara into the wall and scrambles for the machine..just a second too late. Neon stands there, her eyes wide. She's fully black, galaxies swirling in her eyes. And they both start to cry. Chara walks over, knife in hand, her eyes red and glowing.

"I told you.."

"I always win.
