Heavy battle droid/Legends

The heavy battle droid was a line of more powerful versions of B1 battle droids. They were armed with larger and more powerful blasters than the regular B1's E-5 blaster rifles, and wore larger "backpacks". They were used by the Trade Federation during the Invasion of Naboo, and were deactivated after the rise of the Galactic Empire.
