A JMM head was weighing ten kilos.
The droid information broker 8t88 had his head replaced by that of a JMM droid as a prank. The head was cut off and was swallowed by his pet, Grendel. Eventually recovered by Kyle Katarn, who retrieved the coordinates of the Valley of the Jedi held in its memory banks. In the process, he used the droid's head to strike Pic who was jumping on him; the hit smashed him into a bulkhead like a rag doll, killing him.
Imperial Grand Moff Bertroff Hissa was given the arms of a JMM droid after he lost his own during an accident.

The first mention of this droid in Kyle Katarn's Tale identifies it as an espionage droid, while The Complete Star Wars Encyclopedia and Barely Tolerable: Alien Henchmen of the Empire use the term assassin droid.
The droid was named after James McFadden, a.k.a. JMM at JMM's Star Wars Chronology.
