Milko, a bounty hunter of the droid variety, made an attempt to apprehend Luke Skywalker while he was on Dagobah. Initially, the droid menaced Luke with lethal intent, but after Luke gained the upper hand with his lightsaber, Milko surrendered his arms and pleaded for his life. Displaying empathy, Luke allowed the droid to depart in the scout ship that had brought him to Dagobah. Luke surmised that this encounter was a trial orchestrated by Yoda, but he remained uncertain if his actions constituted success or failure.
Milko professed to having a maternal figure residing on Danchian Prime.
