MEL was a modified power droid owned by the pirate Phee Genoa who accompanied her on various expeditions. Rebuilt multiple times, she was designated MEL-221 when she accompanied Genoa and Clone Force 99 on a mission to Skara Nal in the Kaldar Trinary system between 19 BBY and 18 BBY. MEL's body was destroyed by an ancient walker. This barely perturbed Genoa, who stated that she simply kept a back-up of MEL's memory bank and could have it restored. This was then downloaded into a new body, designated MEL-222.
MEL was a modified power droid owned by the pirate Phee Genoa. She traveled to too many uncharted planets to count, so she had MEL keep track of the legends she tracked down over the years. MEL was destroyed many times, so Genoa kept the droid's memory stored on the data bank of her ship, the Providence, and she would be rebuilt. Between 19 BBY and 18 BBY, MEL was designated MEL-221. She, Genoa, and Clone Force 99 were in Ciddarin Scaleback's parlor in Ord Mantell City. Genoa had MEL scan a compass that "Wrecker" and Omega found at a junkyard. The scan helped Genoa realize the compass was from long before their time and had coordinates for the Kaldar Trinary system. Genoa and the clones decided to go to the system to find possible treasure.
While en route to Skara Nal in the system on the Marauder, Genoa and and Omega used MEL as a foot rest while they discussed the latter's adventures. Upon landing on the planet, MEL followed Genoa and the clones into a mountain. After the group managed to open a doorway, Genoa ordered MEL to note the coordinates and wait there. MEL later fled from falling debris caused by an ancient walker, which was activated by Genoa removing the Heart of the Mountain from the walker. MEL was destroyed by a blast from the superlaser. After Genoa and Clone Force 99 disabled the walker, Omega apologized to Genoa about losing MEL, though Genoa stated that MEL's memories were backed up and she would be rebuilt before they headed to Vadnay.
MEL had yellow and blue plating and three black photoreceptors. She was was capable of making beeping sounds and scanning objects by projecting a purple light.
MEL first appeared in "Entombed," the fifth episode of the second season of the Star Wars: The Bad Batch animated series, which aired on January 25, 2023. Mel's full name MEL-221 was identified in the official Walt Disney Company Getty Images release for the episode.
