The Scutiger-100 stealth droid, also known as the millicreep droid, was an insect-like assassin droid used by the Umbaran Militia. Crawling around on six electrified legs, millicreeps were able to use their tail to electrocute an organic being to death. The Umbarans utilized the droids to great effect against the Galactic Republic's clone army during the Battle of Umbara.
