Krath war droid/Legends

The Krath War Droid were powerful a battle droid series created by the Krath, an organization of dark siders founded by the corrupt nobles of the Empress Teta System in 4,000 BBY.

Description
A single Krath War Droid was humanoid in appearance though they could hunch down as animals and race at amazing speeds towards their target due to a gyro-balance assembly system. These droids were designed to surprise and overwhelm their enemies in devastating shock assaults, making them deadly. Despite being easy to manufacture, Krath War Droids had limited cognitive matrices and were programmed only to seek and destroy the greatest threat on the battlefield. Thus, Krath War Droids were often deployed in large numbers to overwhelm the enemy.

They were armed with a melee combat short sword for hacking at close range and a Pulse-wave firing assembly. The attenuated induction spines of this weapon generated a pulse-wave charge and could also be used as a spearlike skewering tool.

History
Following the Jedi/Republic defeat at the Battle of Koros Major in 3,997 BBY, the Jedi held a a great assembly of ten thousand Jedi Master and Jedi Knights on the planet Deneba. The Krath saw this as an oppoturnity to test this new battle droid and to attack their enemies.

Their agents sabotaged the programming of the servant droids that would be at the convocation. The Krath then loaded a Tetan Corsair with a hundred modified life-pods, which each carried a single war droid. Halfway into the Jedi assembly, the sabotaged servant droids suddenly attacked their Jedi owners, causing much confusion and chaos. Meanwhile in orbit, the Tetan Corsair launched its life pods and an army of war droids emerged from the impact craters.

With the element of surprise on their side, the war droids charged at the assembled Jedi at frightening speeds and fired their pulse-wave firing assemblies. Soon, many Jedi fell to these mindless automatons. Jedi Master Arca Jeth fought back against them by using a Force technique he had discovered during the Great Droid Revolution to short-circuit them. However, he eventually fell to a plasma barrage. Though the Jedi had survived the assault, the death toll was apalling. Soon the Galactic Republic and the Jedi succeeded in defeating the Krath along with their Sith and Mandalorian allies.
