“If you are interested in stories with happy endings, you’re better off listening to some other story,” said Tiger as she started to explain her backstory to Gaster as he was writing it down peacefully. In the past, she was a human called Charlotte. She almost died in a fire but was saved by a skeleton, but she died after being in a coma for 7 months. After she died, the skeleton that saved her got her to a lab in the underground and Charlotte was turned into a robot and her identity was changed as well. Charlotte’s new name was Tiger EX and one of Dr. Alphys’s prototypes became Tiger’s brother, Leo EX and she got a twin sister which was the kindness soul that the king captured. All was well but she had to keep a secret, in her upper thigh on her right leg, she had a glitch from the destroyer of universes, that held all the secrets to her past. Every single one and they were revealed to anyone, they would have to be killed but Dr. Alphys was the only living soul that could be told.
