Unidentified super tactical droid/Legends

This Super Tactical Droid was the leader of a mission in order to destroy the Republic Strategy Conference. While the tactical droid was leading the hijacked Republic ship to its destination, the D-Squad landed on board and made a plan to stop the destruction of the conference station. When the hijacked ship was near the station, this tactical droid went to start the countdown for the Rhydonium explosives on board. While he was doing this, R2-D2 came in and began to battle the droid in order to stop him. When it became apparent that Artoo would not be able to stop the detonator, he sped it up while his teammates escaped. This tactical droid was destroyed in the explosion.
