Dr. E. Raser appears as a scientist Yo-kai with gray, spiky hair and a skull with red eyes, a black ghost tail, and a white lab coat. Along with skeletal hands, he has 3 floating chemicals flasks. In one hand, there are 2 flasks with green chemicals. While in the other hand, he holds another flask with the red chemicals. There's a purple glowing aura around all of the flasks. E. Raser also wears a belt with a round buckle. If you look closely at his chest, you'll see (his) ribs are the same color of his mask.
