Alphys is the royal scientist of Mt. Ebott. She is a yellow lizard monster who wears glasses and a lab coat. She's caught on to the deaths that the human has been making, and tries her best to put an end to it. She uses a device which can replicate other attacks that monsters use. Gaster Blasters, lasers, bombs, etc. She isn't the best at fighting, but she can definitely pack a punch to the player. The device also gives Alphys determination overtime, which will eventually cause Alphys to melt.
