Star Wars: Knights of the Old Republic/Zaalbar

Zaalbar joins your party when you and Mission rescue him from the Gamorrean compound in the lower sewers on Taris.

You can't really unlock further dialog by speaking to him, but when you travel to the Wookiee home world Kashyyyk his backstory is revealed, and you can meet his brother Chuundar and father Freyyr.

However, after first entering Rwookrrorro village he's removed from your party until you complete the quest, which isn't necessary to get the Star Map on Kashyyyk: this means it's possible for Zaalbar to remain on Kashyyyk for the rest of the game, either by accident or design.
