Battle Plan Zeta was a military tactic formulated by the battle droid garrison of ST-series super tactical droid General Kalani, on the planet Agamar. Amid the Galactic Civil War in 2 BBY, several members from the rebel Phoenix Cell—Jedis Kanan Jarrus and Ezra Bridger, ex-Clone Captain Rex, Garazeb Orrelios, and C1-10P—traveled to Agamar, seeking munitions to combat the Galactic Empire from a crashed supply ship. While on the surface, the team discovered Kalani's battle droids and were taken prisoner. The general forced them into a battle simulation, where he hoped to end the long-ceased Clone Wars in a Separatist victory. Employing Battle Plan Zeta, exciting the battle droids by its use, the battle ultimately failed as Imperial forces arrived and convinced the two sides to work together and successfully escape Agamar.
