Glitch Kat (Alternate Origin)

Glitch was a human child at the age of 8, she liked to play horror games and very little RPG (who doesnt these days) she booted up Undertale and decided to do genocide but at the end she sold her soul to Chara like normal but instead she LITERALLY died and she was just a soul inside the game until she was revived as Glitch in Alphys' lab. She then found and accidentally absorbed the six human souls causing her to gain the powers she has today. She trains with Undyne to become the first human in the royal guard
