Alphys

Alphys is the second queen of the Underground. She wishes to obtain 7 human souls and break the barrier that traps monsters underground. She is the ex-wife of Undyne.

Personality
Alphys is a kind monster that enjoys gardening, Golden Flower Tea, and Undyne's Butterscotch Pie. Like her daughter, she speaks in southern slang (most notably "howdy" and "golly"). Before her battle, she offers the protagonist many opportunities to explore the Underground and is reluctant to fight them at all; she even suggests that Undyne, the protagonist and herself live as a family if the protagonist spares her. Monsters in the Underground look to Alphys for hope and see her plan to collect seven human SOULs as one of the few things that keep them going. However, Alphys does not want to kill anybody and feels so guilty that she offers the protagonist her SOUL to "leave this cursed place." Though she is miserable because she has killed humans, she feels that it is her duty to her people to battle the protagonist. Alphys lives in the past and wants nothing more than to see her wife and child again, even though they have been gone for a long time. She reiterates the same phrase in her journal every day, perhaps in denial that life has changed since Shyren's demise.

Appearance
She is a yellow, reptilian monster close to the same height as the protagonist. She has protruding teeth.

She wears a yellow crown and purple cape with gold pauldrons. Underneath the cape, she wears a yellow-hued suit of armour.
