Ahsoka Tano is discovered by Master Plo Koon and raised in the Jedi Temple. She graduates to Padawan at an early age, both due to the ongoing Clone Wars and as an effort by Master Yoda to teach Anakin Skywalker a greater sense of responsibility. She wields a green lightsaber.
Ahsoka displays the same type of rash and rebellious behavior that Anakin is known for. She adopts a highly informal attitude towards her new Master and tends to address individuals by nicknames; for example, Anakin is dubbed "Sky Guy" and R2-D2 is referred to as "Artooey." Anakin in turn refers to her as "Snips," in reference to her "snippy" attitude when they first met.
She first appears as a messenger sent by Yoda to Anakin and Obi-Wan Kenobi. Anakin initially believes that Ahsoka is to be Obi-Wan's new Padawan, but she claims that Yoda has in fact assigned her to Anakin, much to his chagrin. It is later revealed that Obi-Wan and Yoda engineered the confusion over who was to be Ahsoka's Master as a means of forcing her upon Anakin in order to make him look like a more responsible Jedi than in his previous recklessness as Obi-Wan's former padawan. After earning Anakin's respect on a dangerous mission to destroy a Separatist shield generator, Ahsoka accompanies him on a quest to rescue the infant son of Jabba the Hutt. Her impetuous nature both annoys and endears her to her Master, but Anakin reveals a newfound affection for his new apprentice, abandoning a duel with Count Dooku when he believes her life to be in danger.
