A rogue B2-series super battle droid, part of the Plazir-15 labor force, malfunctioned in 9 ABY. This was a result of its reprogramming by aggressive nano-droids. These nano-droids had been introduced into a batch of Nepenthé by the commissioner, Helgait. The droid consumed the tainted Nepenthé during a visit to the droid cantina called "The Resistor". However, the nano-droid infection did not take effect until later, while the droid was working at the loading docks. While Din Djarin, the Mandalorian, was investigating the wave of malfunctions in the city alongside Bo-Katan Kryze, he kicked the droid in the leg. This caused the droid to become enraged and punch Djarin, revealing its rogue status. The two Mandalorians pursued the droid through the streets of Plazir, as it attempted to flee by hurling pylons and tables at them, until they finally caught up and destroyed it.
