Executioner droid

"There are only three of these deadly droids known to exist in the whole universe&mdash;it's a collectors' item... and nedless to say, completely unstoppable!"

- Kenna, to Mace Windu

The executioner droid was a very rare battle droid model. During the Clone Wars, there was only three of these deadly droids known to exist in the galaxy. One executioner droid, owned by the collector Kenna, faced Jedi Master Mace Windu aboard Kenna's starship when the Jedi went on a mission to an abandoned planetoid.
