Mad Scientist (hrf004) is a mid-range LEGO minifigure valued at $7.63 on BrickLink. It comes from 1 set, exclusively Scary Laboratory. Not a headline piece, but it adds up. Sellers processing bulk lots should know this figure is worth pulling and listing individually rather than bundling it into a random minifig lot.
The LEGO Mad Scientist (hrf004) is worth $7.63 used and $14.85 new/sealed on average, based on BrickLink sales data from the last 6 months. Prices range from $4.45 to $10.00 depending on condition. Completeness (all accessories included) and print condition are the biggest factors affecting price.
Mad Scientist appears in 1 set: Scary Laboratory (1382-1, ~$195.49). Since it was only in one set, it can't be sourced elsewhere. That scarcity is reflected in the price.
Look for the BrickLink ID hrf004. It's the definitive identifier for this figure. Mad Scientist is made up of 4 parts (a standard minifigure assembly). The parts breakdown on this page shows each component with colors. If you have a loose figure and aren't sure what it is, the brick'em scanner can identify it from a photo in a few seconds.
List it individually on BrickLink with the ID hrf004. Buyers search by part number and will find it. Include clear photos showing condition. At $7.63, it's worth the time to list separately rather than bundling. If you have several LEGO figures, listing them all at once saves on the per-item effort.
