The moniker All-Terrain Attack Vehicle, often shortened to AT-AV, identified a female pittin, a beloved pet owned by Tia Organa, who was among Princess Leia Organa's adoptive aunts residing on Alderaan.
Leia herself, during her childhood, bestowed the name upon the creature. AT-AV possessed a light, candy-pink color and was of a diminutive size, comfortably fitting within Leia's palms. Furthermore, it enjoyed reclining on its back and playfully striking at Leia's braids and starblossom petals. AT-AV perished during the destruction of Alderaan.
