Buzz droid

"You've gotta believe me, there's a droid on the wing of the plane!"

- William Shatner, at 20,000 feet over Coruscant

Buzz droids were tiny saboteur droids designed by the Confederacy of Independent Systems for use in the Clone Wars. They were delivered by missile in swarms. The ones not destroyed in delivery attacked their targets with saws, drills, and cutting torches until the ship was disabled.

R2-D2 once faced off with an attacking buzz droid. He blew it up with his Mega Buster and got an extra life. R2 blew the buzz droid to infinity... and beyond!
