Trade Federation Lackey is an NPC, an alien with a thick Space Japanese accent who was with Valorum/General Grievous when he and the Separatists with them boarded Count Dooku's dreadnought just as it was about to leave Coruscant's orbit after Dooku had kidnapped Chancellor Palpatine.
Revelation of the Sith
Trade Federation Lackey was present with Grievous when Palpatine, Obi-Wan, Anakin, and R2-D2 were caught by Grievous' Combat Cyborgs. When Anakin and Obi-Wan managed to get their laser swords and kill all of Grievous' Cyborgs and Magnaguards, and after Grievous escaped them by breaking through a main hangar window, the Lackey was able to escape along with the other Separatists with him by using the escape pods on Dooku's dreadnought to abandon ship.
