THIS IS A VERY VERY LONG BACKSTORY, SO PROCEED WHEN YOU HAVE A LOT OF FREE TIME

She woke up in a puddle of green goop and glass shards laying in front of a boy in his young teens named Hunter.

She looked at herself, and this is what she looked like:

They started talking, and she found out that she was hooked up to a bunch of wires in a tank filled with the green liquid and that he pushed a button and a hammer came down and smashed the glass she was contained in. They continued to talk, and they got along fairly well. About half an hour later, a scientist walked in and yelled at Cass that she wasn't ready. He didn't mention what for though. Hunter walked up to confront him, but the scientist punched him. Angered, Cass walked up to the scientist, grabbed him by the neck, lifted him up, and said don't mess with my friends. Struggling for air, he pulled out a club and whacked her cheek. She let go of him and fell to the ground, hand on her cheek. She got up and pulled out a sword that came out of nowhere and scared him away.

Hunter just stared in shock as she says "What? Is my sword really that jaw dropping?" He shook his head and pointed a shaky finger at his cheek: the same one she got clubbed on. She raised her hand and felt her cheek. She felt the outline of her blocky jaw and her blocky teeth. She felt around some more, and her fingers got tangled up in thick strings. Hunter handed her a shard of glass to use as a mirror and saw that the strings she tangled her fingers in were wires. Her blocky jaw and teeth made of steel. She realized what she was: a robot.

She blue screened, and when she came back online, Hunter took her to go get it fixed. When they got to his home, Hunter didn't have the parts necessary to fix it. Hunter noticed a hidden switch on her back, and, like the curious person he is, flipped it. Cass suddenly went hostile and scratched him so hard that her exoskeleton hand fell off.

He quickly flipped the switch back, Cass apologized like 10 times, and they continued to go on adventures. They were messing around one day, and she tripped over Hunter and scraped her knee. Off.

A few days later, they met a person named Barbara (whom I have yet to draw because she was my friends idea and they never told me what they looked like) and Cass made her mad. They got into a fight, and she ripped Cass's arm clean off.

The next day, they met a nice kid named Sora (not my character or any of my friends).

Alas, his head was chopped off by the supervillain of the town. Cass was devastated, and decided to keep his necklace and blade. A few days later, they found a lake/river full of some strange liquid. Cass decided to dip her foot in to see if it was safe. Bad idea.

Once they finally find a way safely across the strange goo, Hunter remembered that his friend Garanzo (who was also another idea never told) lived near here. They met this garanzo person and decided to play baseball with Brussels sprouts. They didn't have a pitcher, so there was a machine. At some point during the game, Cass was up to bat and the machine went psycho and shot Cass's eye.

How old were those sprouts man?! Anyways, she could no longer see through that eye, so they left garanzo's house and headed back towards the supposed supervillains hideout. On The way, they ran into the scientist again. He shouted that he knew he couldn't trust Hunter with his plan. This is where people start saying "I ship it..." He then pulled out  a light saber and went to slash Hunter. Cass jumped in the way and took the hit. She protected Hunter because she couldn't live without him and she was already damaged anyways. She did it out of her love for him.

Knowing that he hurt his creation again, the scientist ran away. They finally made it to a shady looking castle, where inside was nothing but probably 5 football courts worth of land, and the supervillain himself, El Dorito. He was so fat he was basically a giant ball. They went to fight him, but Cass noticed an incredibly strong force field. She went and attacked it with all her might. She wore it down until it was almost broken. She was about to land the last hit on the field to finally break it, but the supervillain slapped her and she fell to the ground. A sign then appeared saying Opponent's Turn. She tried to activate her shield, but she used up all her strength attacking his force field. Hunter tried to run to help her, but it was too late. El dorito spawned a huge knife and attacked. Not only did it destroy his last but of force field, but it chopped Cass's head off.

With her final words, she told Hunter to take her soul and gain her power. Her system said lack of oil, and she shut down forever. Through tears, Hunter listened to her and grabbed her soul, pushing it into his chest.

Her soul fused with his, and he managed to defeat and destroy the supervillain once and for all. But it was too much. The power was overwhelming. He went to the all too well known doctor and scientist Alphys to have Cass's soul extracted and given a new body. But, getting a new body is like getting a new phone: any memory of her past adventures were cleared. And, as always, Alphys dun fucked up and accidentally killed Hunter in the process. Alphys was also missing a few pieces so Cass had the same exact wound on her cheek as she did before. Now, she lives with her good friends kennady_noelle, TeddyBearKitkat, SinTrash_, and many sanses in Snowdin!

My god! 1010 words not including this or the start! This is probably by far the longest chapter I have ever written since my first reddit horror story!
