The Nerdlucks are a group of aliens which work for Mr. Swackhammer. In their original form they are small, weak and not particularly intelligent. However, they have the ability to steal other creatures' abilities and assume a new, much larger and more menacing form.
Their only other appearance to date has been a cameo in the Animaniacs and Pinky and the Brain special "Star Warners" as patrons at the cantina bar.
The Nerdlucks are small insectoid aliens who wear bowties, they have bug-like eyes, antennas, lizard-like noses, and three fingers.
