When his father died in a podrace, his uncle sold Doby's older sister Djulla into slavery. Ratts's podracing colleague, Sebulba, bought her. To get her freedom back, Doby's brother Deland would compete in a podrace against Sebulba's son Hekula. Doby was Deland's race mechanic.
But, as always, Sebulba cheated, and he broke Deland's arm. Fortunately, a young Jedi named Anakin Skywalker raced on Deland's behalf as one of Sebulba's one-time rivals, in Deland's vehicle, which was sabotaged by Sebulba. Anakin won, freeing and sending the happy three Aleenas back to their home.
Obi-Wan Kenobi soon found out though that Doby Tyrell and Deland Tyerell cheated on the podrace by getting a faster map sent by Maxo Vista to them. Maxo Vista also sabotaged the podracer, but Anakin Skywalker pulled through. It turned out that they had used Anakin Skywalker to free their sister.
Later on, when Deland started the Ratts Tyerell Foundation, Doby played an important part in it.
