Royal Scientist Alphys serves as the Royal Scientist, the primary guide for the Hotland region, and the gatekeeper to the dark lore of Undertale. She is a nervous, anime-obsessed dinosaur who accidentally created the game's ultimate antagonist.


Just alphys. I don't really know if this is ture or not but this is how I see her. I think she is shy Smart (of course) Nervous? Not really Likes undyne, 100% ture And uh.. whatever you see her Alphys acts like a deeply anxious, socially awkward nerd who hides immense guilt, low self-esteem, and depression behind an obsessive love for anime.

Alphys wants acceptance, forgiveness, and a way to undo her past mistakes. Because she lives with crippling guilt, her true desires are entirely about escaping her self-inflicted isolation.1.

She landed the job by deceiving King Asgore.The Ghost in the Shell: A lonely ghost monster (Napstablook's cousin) desperately wanted a physical body to become a glamorous star. Alphys designed a mechanical, robotic shell for them.The Royal Lie: Alphys presented this robot—Mettaton—to King Asgore, claiming she had invented a highly advanced, artificial intelligence engineered specifically for hunting humans. Asgore was so amazed that he immediately appointed her as the new Royal Scientist, unaware that Mettaton was actually just a ghost possessing a metal body.2.
