W. D. Gaster was the Royal Scientist before Alphys, responsible for creating the CORE[1] and said to have disappeared. Characters such as the River Person and Gaster's Followers hint at his existence. Now, he is currently the Royal Scientist, being assisted by Alphys and Sans. He's helding Bernardo captive for recovery, and he should break out any moment sooner. Bernardo is likely a step-son to him. If anything happens, Gaster will train him.
