An advanced toolkit has been integrated into BD-unit Backpack Droid, allowing it to perform sophisticated and large-scale repairs on other droids or technology.

BD-unit Backpack Droid has received specialized upgrades and programming to all its motivators and actuators, allowing for much smoother and more subtle movements than a standard BD-unit Backpack Droid with a slightly reduced reflex time and movement speed.

BD-unit Backpack Droid has developed a personality around the concept of a caretaker. It has assumed the needs of its owner to be its prime directive, even such tasks that have not been requested of it. This results in BD-unit Backpack Droid often flitting about in an attempt to meet any possible task before it is necessary, including menial tasks.
