Droideka

Droidekas, also known as  destroyer droids (destroyers for short), or as rollies in clone trooper slang, were a type of battle droid used by the Trade Federation during the Invasion of Naboo and, later, by the Confederacy of Independent Systems during the Clone Wars. Manufactured by the Colicoids on Colla IV, droidekas were dangerous and deadly, designed to exterminate their adversaries with extreme prejudice. They could transform their shape by curling into a ball and moving up to 75 kilometers per hour across a surface, or stand on three legs and utilize a shield generator while firing at a target. Before the Invasion of Naboo, Jedi Master Qui-Gon Jinn and his apprentice Obi-Wan Kenobi had to face droidekas on a Droid Control Ship.

Shelled in bronzium armor, droidekas came equipped with numerous armaments, both defensive and offensive. In particular, they made use of twin repeating blaster cannons and personal deflector shield generators, which meant that when clones conducted mass attacks, they were scythed down by the droideka's twin repeating blaster cannons, and nothing could be done, unless the clones could get an EMP through the shield, or artillery could be called in. Some destroyers were referred to with he/him pronouns while others were referred to with she/her. Additionally, a droideka could be referred to with it/its.
