Star Wars: EotE - Debts to Pay
T3P0 was developed by the base’s sci-tech division to handle all operations in the event of a Omega Level Event.
T3P0 maintains all life support functions, security functions, and several other systems that have been deemed as “classified”.
His quirky personality and voice were initially established as a joke by one of the programers, but after T3P0’s go-live implementation, they were never able to convince the AI that they should be allowed to change his voice.
In the years following the cataclysm, T3P0 (teepo) has been the bases care-taker. It was only once the generators stopped working and the battery back-up died that Teepo was brought offline.
