Dr. Kiln (Or, Doctor Henerik Kilnklein) is a mad scientist in the very sense of the stereotype. Originally mentioned in the manual of C2: Judgement Clay as having caused the chaos in the game and creating evil clones of each character, he makes his first in-game debut in ClayFighter 63⅓ as the main villain. He is voiced by Charlie Adler and his stage is Kiln's Labratory.
