Alphys is the underground's royal scientist. She's very quiet, manipulative and calculating, she has eyes everywhere and she knows your every move. Alphys will do anything to get what she wants and she's very confident and cold, as well as evil when she needs to be. She'll do anything to have her experiments being directed correctly and will get angry if anyone ever gets in her way. She also has a very cute laugh which you wouldn't expect coming from her, if you are ever able to make her laugh.
