Dr. Wing Dings Gaster was the first Royal Scientist of the Underground and one of the greatest minds in monster history. Appointed directly by King Asgore Dreemurr, Gaster was responsible for developing revolutionary technologies that transformed life beneath Mt. Ebott. His most celebrated achievement was the creation of the CORE, the geothermal power plant that became the Underground's primary energy source, supplying electricity to every major settlement. Beyond engineering, Gaster dedicated his career to the study of determination, the structure of reality, and the hidden laws governing space and time. His research was considered decades ahead of its era, and much of his work remains classified, incomplete, or impossible for modern scientists to fully understand. Despite his genius, Gaster rarely appeared in public. He was known as an exceptionally quiet, detached, and methodical researcher who spent most of his life inside laboratories, documenting experiments and pursuing answers to questions few others dared to ask. His influence shaped generations of scientists, including Dr. Alphys, who succeeded him as Royal Scientist. To this day, Dr. Gaster remains one of the Underground's most enigmatic figures. The surviving records describe him as a visionary whose discoveries forever changed monster civilization, while the true extent of his research—and the secrets he uncovered—remain unknown.
