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 Professor Brainstein (uagt023) is worth $5.03 used and $7.75 new/sealed on average, based on BrickLink sales data from the last 6 months.

Look for the BrickLink ID uagt023. It's the definitive identifier for this figure. Professor Brainstein 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 uagt023. Buyers search by part number and will find it. Include clear photos showing condition. At $5.03, it's worth the time to list separately rather than bundling. If you have several Ultra Agents figures, listing them all at once saves on the per-item effort.
