The small droid who accompanies Cal Kestis in Star Wars Jedi: Fallen Order is BD-1.
Cal meets BD-1 on Bogano while investigating an ancient Zeffo vault connected to Jedi Master Eno Cordova. The droid was once Cordova’s companion and carries recordings that help Cal understand the vault and the Jedi Holocron hidden inside it.
BD-1 is more than a mascot. He scans objects, projects map data, slices certain machines, and carries Stim Canisters that heal Cal during combat. His expressive movements and electronic sounds make him one of Cal’s closest companions despite having no spoken dialogue.
A common mix-up is BB-8, another famous Star Wars droid with a rounded body. BD-1 has a distinctive bipedal design, large optical lenses, and a birdlike silhouette. He returns alongside Cal in Star Wars Jedi: Survivor.
