TV 94 aboard Grevious's ship

The General's description of your tactics have been 100% accurate today. Very impressive, even by my standards.
~ TV 94 to Anakin Skywalker
TV 94 served as the secondary antagonist of Episode "Grevious Intrigue" from Star Wars: the Clone Wars. 

He served directly under General Grevious, Supreme Commander of the Separatists Droid armies, and was possibly his second in command as he was his personal Tactical Droid. He served aboard the General's Recusant-class light destroyer when Jedi Master Eath Koth was captured and tortured by Grevious. When Republic forces engaged with Grevious's fleet, TV-94 was left in charge of the prisoner while Grevious boarded one of the ships to personally confront Obi Wan Kanobi. TV-94 was confronted by both Jedis Anakin Skywalker and Adi Gallia who intended on saving Eath, but several Commando Droids appeared to assist TV-94. TV-94 began torturing the prisoner but Anakin cut off his hand, which turned into a small battle between the Jedi and droids. When TV-94 finally got his hand back so he can finally kill Koth, he realised he couldn't push the button due to a lack of hand, so Anakin cut down the droid and rescued Eath.
