The Zillo Beast Strikes Back (2x19)

Air date: Apr 16, 2010

The most dangerous beast is the beast within. When the Zillo Beast is brought back to Coruscant in hopes of learning the secret of its impenetrable armor, it instead breaks loose and rampages across the city-planet. As the clones prepare to kill it with poison gas, the Jedi are again trapped in a moral conflict between the value of its life and that of the planet's civilian populace
