Pato Ado was an Ithorian male, specifically an Ithorian of the male variety, who worked as an ecologist and xenobiologist. He encountered Meetra Surik while she was on Dantooine. Having dedicated much of his life to the study of Dantooine's flora and fauna, he felt a strong urge to go back to his herd residing on Telos so he could contribute to the ongoing restoration project there. While awaiting transportation to Telos, he developed an interest in playing pazaak as a pastime. Initially, numerous people were eager to play against him; however, as his proficiency increased, fewer and fewer individuals were interested in playing. Consequently, he began using the rare and valuable armor components he utilized in his research as rewards for unique pazaak matches.
Meetra Surik eventually won all of his credits after a series of games, which led Pato to put his armor components up as collateral; this was the first time he had ever lost his components. The Ithorian did not harbor any resentment towards Surik, and simply found pleasure in playing against a worthy adversary.
The player has the option of inviting Pato Ado to become a member of the Khoonda Militia, but he turns down the offer. He also has a collection of pazaak cards available for purchase.
In contrast to the majority of pazaak players, Ado is happy to keep playing matches with the player even after his components have been taken, without any stakes.
