A male Falleen was taken prisoner in 19 BBY by a band of Zygerrian slavers. This Falleen, together with a human and a Falleen female youngster, were held captive by the enslavers in the remnants of Old Ord Mantell City located on Ord Mantell, with the Zygerrian commander Raney supervising them.
A Clone Force 99 took on a contract to rescue a child named Muchi from the slaver's camp during 19 BBY. Upon their arrival at the ruins, they mistakenly believed the Falleen girl was their target, as she was the only child in sight. The clones effectively diverted the Zygerrians' attention by setting loose a confined rancor, which enabled them to liberate the Falleen captives. Nevertheless, when Omega, a member of the squad, called the girl Muchi, the Falleen prisoner clarified that Muchi was actually the rancor. Despite this confusion, the clones freed the Falleen and escorted them to speeder bikes positioned at the city's southern gateway. The Falleen then used the bikes to flee the city with the child, expressing gratitude to their saviors.
The Falleen prisoner was featured in the Star Wars: The Bad Batch episode entitled "Rampage," which was the fifth episode of the series. It was made available on Disney+ on May 28th, 2021. Liam O'Brien played the part.
