Alphys is a yellow, reptilian monster with scales with sharp, protruding teeth. During her battle with the protagonist, she wears gray armor and wields an axe.
In her Alpha form, she seems to have longer, sharper scales. She also has a yellow, laser-like, light in the shape of a lighting bolt coming out of her left eye.
Alphys behaves much like Undyne in the original Undertale.
Undyne - Undyne and Alphys have crushes on one another.
Toriel - Alphys tried to go up and fight Toriel but she fails at it. Then, Toriel trained Alphys how to fight, and soon, Alphys became head of the Royal Guard.
Sans - Alphys trains Sans even though she knows that he'll never be in the royal guard because he is too nice (she wouldn't tell him this because he would be sad), so Alphys taught him how to cook instead.
