long ago, two races ruled over the earth, HUMANS and MONSTERS. One day, war broke out between the two races. After a long battle, the HUMANS were victorious. Dust from the MONSTERS blew everywhere.They trapped the remaining MONSTERS underground with a magic spell. Legend says those who climb the mountain never return....
So the story begins. =)
Chara, get outta here! I'm telling your story here!
When Chara died, Asriel absorbed their soul, crossed the barrier,and went to the surface. Chara's last request was to see the golden flowers from their village... when Asriel laid their body on the flowers, the villagers attacked him thinking he had killed the child. Chara had always hated the villagers and wanted Asriel to kill them. He refused, and returned Underground, still smiling...His dust spilled across the garden, and his DETERMINATION from Chara's soul went into a flower, and he became Flowey. A merciless emotionless nutjob.
At the end of the Genocide route, where you have killed everyone, including Flowey(Asriel soulless). They thank you. They say your determination revived them, and every time you gained a Level Of ViolencE, they grew stronger, until they stood before you... (this is a theory)and they watched you kill their brother and only friend... they hated you for it.
When you meet Chara, they tell you all things on the last slide, and say,
"There is nothing left for us here. Let us erase this pointless world, and move on to the next. " because it's true. You killed everyone. You destroyed their brother. If you refuse, something scary happens. Their eyes disappear. They jump out at the player screaming"SINCE WHEN WERE YOU THE ONE IN CONTROL?" Their face melting. And if you accept, the world goes into a black void. They question you and ask for your soul in return for the world to return.
If you accept, their eyes disappear, and they say,"you've been a great partner. WE'LL BE TOGETHER, WO'NT WE?" And the game starts again. You may think Chara is such a bad guy.., but you are the bad guy. They have no choice to help you. They're attached to you. You could have been Pacifist and spared their lives, but you killed them all. You monster.
