This Zillo Beast was the last member of its kind. In 22 BBY, the beast was awakened during the Battle of Malastare of the Clone Wars and caused chaos on Malastare, destroying Dug camps and Republic troops and vehicles alike. The Republic managed to stun the Zillo beast by using RX-200 Falchion-class assault tanks. It was brought to Coruscant for study, but it was killed there when it broke out of its research facility.
