Set in the prequel Star Wars era, The Yoda Chronicles features the one and only Yoda -- the Jedi Master who has seen it all, done it all and taught generations of Jedi Knights. With help from a fresh class of Padawans, Yoda leads the Jedi in a desperate fight to stop Darth Sidious and his minions from creating a new super-weapon that could crush the Republic and win the war for the forces of evil.
In the Menace of the Sith, Darth Sidious shows off the new Sith clone, JEK 14, who is an extremely powerful weapon of the dark side. However, JEK has a mind of his own and wants to be his own master. Suddenly, both the Jedi and the Sith try to win him over. It remains to be seen which side he chooses, good or evil.
