- "Ah hah hah hah! They called me mad at the university...and they were right!"
- ―Crazy Scientist
The Crazy Scientist has messy gray hair, a white lab coat with a few lime green spills on it, and black legs with a white hip piece. He comes with a new part, which is a conical flask. It is clear with green mixed into the lower section.
- At two per box, he was the rarest minifigure in Series 4.
- His hair is made out of a type of rubber, similar to the Punk Rocker's hair. The hairpiece was featured in the Agents theme on Dr. Inferno and Dr. D. Zaster.
- His "monster" is also included in the same series based off of the "Frankenstein" story and films.
