Anakin Skywalker: "There are hundred of droids with red eyes."
Obi-Wan Kenobi: "But there aren't many droids that can kill Jedi." - Obi-Wan Kenobi, Garri, and Anakin Skywalker
IG-100 MagnaGuards,[7] or Magna Guard, were a type of battle droid created by Holowan Mechanicals.[1] They were a favorite of General Grievous, who used them as his bodyguards during the Clone Wars, though they were also known to accompany other high-ranking Separatist personnel. MagnaGuards were equipped with electrostaffs that could be used against Jedi lightsabers and were capable of continuing a fight even with the loss of one or multiple limbs or even their heads. They were worthy competitors even to the most skilled Jedi, one was even able to back Obi-Wan Kenobi into a corner. MagnaGuards usually fought in at least pairs of two, one to occupy the Jedi's lightsaber and one to attack from the unguarded flanks or behind.[8] Their presence signified that a high ranking commander was nearby, and the droids automatically outranked other battle droids deployed.
