ĭuring her travels Meetra Surik visited to the Telos factory along with HK-47. Eventually, the crime lord G0-T0, who was in fact a planning droid previously assigned to Telos IV, discovered the HK-50 manufacturing facility and reactivated it, disseminating the new model assassin droids throughout the galaxy searching for the Jedi.
Revan was captured and his memory was erased before this plan could be realized, however, and the production on the HK-50 model ceases for several years. HK-47 became the basis for a new model of HK-series assassin droids: the HK-50. After Darth Revan witnessed first-hand the abilities of the HK-47 assassin droid he created, he decided that more droids of this design would make excellent agents for his purposes.
