Zillo Beast

The Zillo Beast was a semi-sentient, reptilian species endemic to the planet Malastare. This gargantuan creature was believed to have long been extinct by the Dugs; during the Battle of Malastare, however, the last specimen alive was inadvertently unearthed by an electro-proton bomb used by the Galactic Republic.

Supreme Chancellor Sheev Palpatine sought to use the Zillo Beast's indestructible hide to aid the Grand Army of the Republic. Shortly after the creature was brought to Coruscant for study, however, it broke free from its restraints and rampaged through the capital. In the end, the Jedi and Republic army were left with no other choice but to kill the Zillo Beast using a powerful toxin.
