XR-85
the Arakyd tank droid, it is an sentient attack vehicle. Designed by the remnants of the Empire from pirated pathway matrices stolen from the R7 astromech droid, the first droid was finalized during Thrawn's reign of terror against the New Republic. However, the droid was not fully realized until Umak Leth brought the idea before the reborn Emperor Palpatine. He worked with Arakyd to design the tank droid, which measured 32 meters in length, nearly 30 meters in height, and moved about on a pair of treads. Each tank was armed with a heavy particle cannon, two light turbolasers, four twin heavy repeating blasters, and a Golan Arms DF.9 weapons turret mounted on its back. It had a top speed of 70 kilometers per hour, and could travel equally well on land or in water up to fifteen meters deep. Although the XR-85 was highly successful, mass-production of the sentient droid brain was cost-prohibitive.
