Ahsoka Tano was a Force-sensitive Togruta female former Jedi Padawan who, after the Clone Wars, helped establish a network of various rebel cells against the Galactic Empire. Tano was discovered on her homeworld of Shili by Jedi Master Plo Koon, who brought her to the Jedi Temple on Coruscant to receive Jedi training. Following the outbreak of the Clone Wars, Jedi Grand Master Yoda assigned the young Tano to be the Padawan learner of Jedi Knight Anakin Skywalker, who nicknamed her "Snips" when she joined him at the Battle of Christophsis. Whereas Tano was eager to prove herself, Skywalker had a reputation for recklessness, and they had a rather difficult start as master and apprentice. Yet they worked together to rescue Rotta, the son of crime lord Jabba Desilijic Tiure, and returned Rotta to his father, thus facilitating a crucial alliance between the Hutt Clan and the Galactic Republic.

As a commander in the Grand Army of the Republic, Tano found a mentor in Clone Captain Rex of the 501st Legion, with whom she and Skywalker collaborated to lead frontline campaigns against the Confederacy of Independent Systems. In her first command position at the Battle of Ryloth, Tano disobeyed orders and lost her entire squadron of pilots, but she rebounded and helped secure a victory at Ryloth. Her assignments pitted her against a variety of opponents, from General Grievous and Sith apprentice Asajj Ventress to bounty hunters such as Cad Bane and Aurra Sing. Over time, she matured into a respected leader, contributing to key Republic victories like the Second Battle of Geonosis and the Battle of Mon Cala. She even died during a series of events on Mortis, but the Daughter, a Force wielder who personified the light side, sacrificed herself to bring Tano back to life.
