    It is a undertale genocide run but has some major tweaks in it.anything undertale related belongs to DAT BOI TOBY FOX..And some of the ocs is obviously mine, but try to follow along And don't hate. Idk If I will continue it your guys choice really...enjoy! It wasn't a normal genocide run like you have seen it before .The human was confused but didn't care that there were more new important monsters. It means more EXP and LV for them . Now they have to face a more difficult monster that is angered at them for killing his two sons and daughter. Who will win this battle to the death? Chara or Gaster?

    Erin was a gaster blaster who was made by dr Gaster for his son Sans. After a few years Sans had grown up and had left the lab taking Erin with him, he had other gaster blasters but preferred his only female blaster. They confined everything with one another but when frisk comes into the picture, things get really awkward for Erin as she might just be given away by the little brown haired rascal. She may even have possible powers only Dr Gaster knew

    In this fanfiction plans Ib (my OC) to prank Understitched Gaster (from Gasterblaster7659) and forces him to a dinner. She trys a lot to make Gaster embarrassed and uncomfortable their whole meeting. Ib makes suggestive jokes and trys to flirt, but Gaster avoid them. Though at the end he does something she doesn't expect. This short story is mainly just for fun and is meant to make my good friend Gasterblaster7659 embarrased. So please don't take anything seriously

    𝐀𝐧𝐨𝐭𝐡𝐞𝐫 𝐝𝐚𝐲, 𝐚𝐧𝐨𝐭𝐡𝐞𝐫 𝐫𝐞𝐬𝐞𝐭. Sans, a lazy short skeleton is a victim, along with the entirety of his home and family to a human named Frisk and their friend Chara. After the thousands of times that Frisk has murdered the entire Underground, Sans didn't even know why he kept fighting. It was like he was some type of mindless NPC. However, one day was different. Even in the slightest change, Sans found an opportunity to strike, and finally kill Frisk. However, that was all false hope. Frisk was transported to another world, meeting someone who looked oddly similar to Sans, however, he had a dark shape to him, and black goo surrounded his body. He easily overpowered them, yet, he offered something. That's when Frisk knew, this was the start of an entirely new story. A new timeline. -Inspirations- ᴜɴᴅᴇʀᴠᴇʀꜱᴇ ᴄᴏᴍʙᴀᴛ ɢᴏᴅꜱ (ᴊʜᴀɴᴢᴏᴜ) ʜᴏᴡ ᴛᴏ ɢʀᴇᴇᴛ ᴀ ɴᴇᴡ ᴘᴀʟ (ᴜɴᴅᴇʀᴛᴀʟᴇ ᴄᴏᴍɪᴄ) ᴀ ʙɪᴛ ᴏꜰ ɪᴄʜɪᴋᴀ -Best Achievements- ɴᴏɴᴇ ᴊᴜꜱᴛ ʏᴇᴛ! -Length Expectancy- ᴄʜᴀᴘᴛᴇʀꜱ ʟᴇɴɢᴛʜ: 1.8-2.8ᴋ ᴡᴏʀᴅꜱ ꜱᴛᴏʀʏ ʟᴇɴɢᴛʜ: 15~20 ᴄʜᴀᴘᴛᴇʀꜱ "𝑻𝒉𝒂𝒕'𝒔 𝒂𝒍𝒍, 𝒏𝒆𝒓𝒅 𝒐𝒖𝒕 𝒃𝒓𝒂𝒉!" - 𝑭𝒓𝒆𝒔𝒉 P.S: THIS STORY IS IN OWNERSHIP OF @ThatWriterBoi, I AM JUST POSTING THIS ALONG WITH HIM SO IT COULD GET MORE RECOGNITION!

    This is a GasterBlaster!Underswap!Sans fic in the world of Underswap. Sans (or Blueberry) is a ten-year-old skeleton who isn't allowed to leave home. While his father (Gaster) does his job at a local party store, Papyrus is in charge of making sure his little brother stays safe and at home. But while Papyrus was out getting food, and unexpected visit came to their house, making the curious Sans, follow her and find out something that he had never saw in himself. I don't own Underswap or Undertale. Neither do I own the Gaster Blaster Sans AU. Hope you like it anyway! ^^
