"Chara was fugitive due to an Small accident and ran into underground, Found Asriel, Asriel tried to kill him to get Human Souls but Toriel Arrived to stop Asriel because she sees Chara was way too powerful so Toriel tried to convince (and lie) to Chara about going into Sans Castle, of course Toriel was thinking that maybe Monster are free at last but Sans was suspicious how could Human have such powerful magic and thus convince Chara to sent to lab for experiment, Monster eventually Find out it indeed was extremely powerful, around 2 Human Soul to be exact but due to it unstable Nature, They test a fragments of it on heavily injured Monster and they immediately Melt slowly and became a Puddle after 4 minutes despite life support, Chara was allowed to be alive for a while as They're experimented to see if there a way to make their Soul stable enough for Monster to use or if there a way to manifest such power for Monsters to use, you may wonder why Sans didn't just use Other Human Soul to make them strong enough to handle Chara Soul or leave early in the first place considering his personality? It pretty simple, No other Human have actually fallen down there yet, Chara remain the first Human to falls and about Mettacrit and Napstarblook I have different plan for them!"
