The Imperial Royal Guard serve the evil Emperor and Lord Vader as their personal bodyguards, assassins, and executioners.They had crimson robes and sinister helmets, members of the Royal Guard are always at Palpatine and Vader’s side (in Vader's case not always )and remain fanatically loyal to their dark vision. Vader has selected each member of the elite Royal Guard from the ranks of only the most successful Stormtroopers. Criteria for admission into the Imperial Royal Guard include great strength and intelligence, along with an unwavering devotion to the Empire. Despite their constant presence alongside the Emperor and Vader, very little is known about the workings of the Royal Guard. The unit is so secretive that suggestions as to its numbers have ranged from 50 to tens of
thousands. Although trained in the use of many weapons, the Royal Guard typically wield Force pikes, which they combine with hand-to-hand attacks during combat. They are also somewhat resistant to the Force, allowing them to withstand Force powers that would easily dispatch regular Stormtroopers.
