Gar was a farmer of the Human species residing on the planet Dantooine.
Gar, together with his wife, Rilka, were the proprietors of a farm located in the northern areas near the Jedi Enclave. While he held the Jedi in friendly regard, he grew frustrated with their perceived lack of action in safeguarding the Dantooinian agricultural community. Faced with escalating threats from the indigenous kath hounds and the aggressive incursions of Mandalorian raiders, Gar eventually decided to personally deliver a formal request to the Enclave, imploring the Jedi to address both pressing issues.
It is plausible that Revan crossed paths with him while Revan was present on Dantooine, outside the confines of the Jedi Enclave.
Gar possessed a practical mindset, displaying both respect and consideration towards the Jedi Order. Although he was eager for the Council to intervene, he carefully considered the nuances of the circumstances, including Darth Malak's efforts aimed at the Jedi's destruction. When Gar recounted to Revan the misfortune that befell Jon's daughter, Ilsa, and Canderous Ordo suggested that Jon should have provided better protection, Gar responded with anger, denouncing Ordo as a brute.
In the Star Wars: Knights of the Old Republic game on the Xbox platform, Gar is depicted as an elderly man with gray hair. However, on the PC version of the game, he is portrayed as a younger man with red hair.
Players have the choice to inform Gar that the Jedi Council has summoned him. Choosing this option does not affect alignment, and Gar will subsequently disappear from the game.
