Darth Vader (Formely Anakin Skywalker) is a sith lord. He is the student to Emperor Palpatine.
Darth Vader and a part of the Galactic Empire arrived at Ninjago City and used the Borg Tower as their base. Vader herad about that five ninja are protecting the city but warned the officers about that even they can't stop the Empire as their powers are no match for The Force. Later he fought The Ninja and defeated them. Sensei Wu arrived but even he was unable to stop Vader. Later Emperot Palpatine arrived and later two Stormtroopers brought them a hooded man with pale skin and red eyes. The man was put into prison beacuse Vader and Palpatine did not know what they should do with him. Later they have told about the sons of Garmadon and the Oni Masks. They went to their base and managed to defeat and capture the members of the S.O.G including Harumi. They have also stole the Oni Masks. Later at Borg Tower, Vader spoke to the inprisoned S.O.G and Harumi told Vader that he does not have power over in Ninjago. Vader then Force-choked Harumi and told the S.O.G that insulting the power of the Force will have horrible results.
