    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?

    Before the events of Undertale. . . All was well in the underground. A skeleton named Papyrus was training to be in the Royal Guard and his skeleton brother Sans was part of the Royal Scientist along with their father Gaster. All it took was one day to change the skeleton family forever. Undertale belongs to Toby Fox Disclaimer: This MY version of how Gaster Sans became Gaster Sans and eventually Gaster Blaster Gaster Sans. This means it is NOT just Gaster Sans.

    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!
