The Uranium 235 core was the device that animated and powered the bio-mechanical demonoid Adam. With the core, Adam could go indefinitely without food, water, or sleep and survive any wound.[1]
History[]
Jonathan, during his time as the Initiative's tactician, found out in Professor Walsh's original design schematics for Adam that his power source was not biological, but a a small reservoir of uranium 235. According to Jonathan, the core was capable of lasting "essentially forever."[1]
The Scooby Gang determined that they needed to extract the uranium core from Adam in order to defeat him. Riley informed them it was embedded inside Adam's chest, probably near the spine. The group considered researching a spell capable of extracting uranium or paralyzing Adam to perform an exploratory surgery on him, but they would be unable to either find or perform such spells.[2]
Ultimately, Buffy, Willow, Xander, and Giles performed an enjoining spell that combined their abilities, which allowed them to punch through Adam's chest, reach into the uranium core, and remove it from inside Adam. Without the core, Adam fell dead on the floor. The Scoobies then cast a Sumerian spell that levitated the core from Buffy's hand and magically disappeared.[2]
