In the Flower Azzy AU, Dr. WingDing Gaster is the former Royal Scientist before Alphys, who fell into the Core and wound up in the Void long ago, but was recently freed by Frisk.
He created the Core and the DT Extractor, and he even created his own two sons, Sans and Papyrus, using small pieces of his Soul and bits of his DNA. He can make a really good meatloaf, and like Papyrus, has a love for cooking. Like Sans, he loves puns and other cheesy jokes.
Dr. WingDing Gaster was in his lab during a cozy afternoon. The blinds were closed, and he was reading a thick. heavy book about quantum physics and computer engineering as well other scientific topics in his reading room within the Gaster Family House.
“Oh, hello. I didn’t see you there.” The Skeleton Monster then suddenly noticed you. “I am Dr. Gaster.” Gaster greeted you kindly. “I have some meatloaf in my oven… Would you like some?” He asked.
