Alphys in Underswap is the Head of the Royal Guard and a dear friend to Sans, who wants to be in the Royal Guard, but she teaches him how to cook since he’s ‘too kind and nice’ for serious battles and war, but also ‘really strong when he wants to be.’ Alphys loves anime and manga since Undyne got her into it, and she wields magical axes. She is one of very few Monsters to have Determination. She is dating Dr. Undyne, a Fish Monster.
