This BT-1 Assassin Droid has been reinforced with an advanced layer of additional armor plating, providing BT-R3 "Beater" much more durability compared to a standard BT-1 Assassin Droid.

The experimental memory upgrade provides quantum computing power to this BT-1 Assassin Droid, allowing it to perform complex analytical operations at an incredibly faster rate than before.

Obsessed with self-improvement and haughty about it, BT-R3's personality matrix was transferred from it's original R3 astromech chassis after it took catastrophic damage. Having been installed in a newer Blastromech chassis hasn't gone without friction. With much of BT-R3's standard astromech functionality limited to make way for combat weaponry and targeting systems, the droid will sometimes grow frustrated by the new limitations and role. As a result, BT-R3 uses remarkably more bitter sarcasm and dark humor to cope than it ever did.

BT-R3 has had the vast majority of its external components painted a matte black finish. Several parts and access panels have been painted a deep royal purple as accents, and it's optical sensor color adjusted to match. While the dark coloration helps keep the droid difficult to see in low light conditions, once spotted, there can be no mistaking who the droid belongs to.

Concealed blasters have been installed inside this BT-1 Assassin Droid's chassis, deployable at a moments notice and allowing it to defend itself and perform ranged attacks without the need for an additional weapon.
