Star Wars: Knights of the Old Republic/T3-M4

T3-M4 joins your party after getting him from Droids by Janice in the Upper City North on Taris: while he must be a member of your party to open the security door to the Sith base to allow you to escape the planet, after entering the base you can exit immediately to remove him again.

Although he communicates in a series of beeps and boops, their meaning is made clear by your responses, or those of another party member. You can't unlock further dialog by speaking to him, but he may comment during dialog when in your party, although unlocking this may also be conditional on others being added or removed, among other things:


 * Dantooine


 * Tatooine


 * Manaan


 * Korriban


 * Leviathan


 * Star Forge System
