Lin-D was a masculine-programmed entertainment droid designed to tell jokes and make wisecracks. With a humanoid design, and gray, silver, and orange plating, Lin-D's facial features sported a perpetual grin and a pair of adjustable, white photoreceptors—both qualities that underscored his flippant attitude and penchant for making light of any situation. Indeed, Lin-D's loquaciousness proved unbearable to some; the protocol droid C-3PO found him to be quite annoying.
