B1 battle droid/Legends

"Useless things. A greater danger to us than to Jedi."

- General Grievous

B1 battle droids were the battle droids that made up the backbone of the Trade Federation Droid Army and the Separatist Droid Army. It was the successor of the hunter-killer droid.

B1s were perhaps the most numerical soldiers ever, and, unlike most organic soldiers, they were capable of action in hostile environments like underwater or in space.

Design
"Roger, roger."

- Typical response of a B1 battle droid

B1 battle droids' heads were designed to imitate the shape of a dead Neimoidian's skull. In this way, they were intended to strike fear into an enemy's heart. In addition, they vaguely resembled Geonosian bodies.

B1 battle droids were physically identical to their direct predecessor, the OOM security battle droid; unlike OOM models, they did not have color marked on the head, shoulders, and/or chest to distinguish function. However, some were painted with different colors to blend into a certain environment.

B1s were usually slaved to a central control mainframe located on a remote starship or some other well-defended facility. However, this could lead to massive failure if the central control mainframe was destroyed, such as during the Battle of Naboo, in which Anakin Skywalker destroyed the Droid Control Ship. The monumental defeat at Naboo spurred interest in independent battle droids, and this technique gained ground following the battle.



In extreme cases, the droids would deactivate the electromagnets that kept its limbs attatched. During the Clone Wars, clone troopers learned to aim at the hips, torsos, and arm joints of the B1s to quickly destroy them.

B1s were designed for cheap mass-production. Other models, like droidekas, B2 super battle droids, grapple droids, and air battle droids, were more expensive and powerful.

Battle droids used E-5 blaster rifles, blaster pistols, and thermal detonators in combat. They spoke with a monotonous, mechanical voice. The voice varied between units around the time of the Battle of Naboo, but by the end of the Clone Wars, the voices seemed to be standardized.

History
"Send more droids against the Jedi Knight! Their bodies are making a pile so high that he will never be able to cross it!"

- Sentepeth Findos, speaking of Kit Fisto

Following the Naboo crisis, the Galactic Republic enacted strict legislation that prohibited the use of droid armies and the development of military hardware. The Trade Federation, however, relocated its droid foundries and laboratories to remote territories far from the Republic's jurisdiction like Geonosis. The Trade Federation also developed a new generation of B1s with enhanced intelligence and independence. Some, towards the end of the war, even began to express more emotional traits such as sarcasm.



After the Trade Federation joined the Confederacy of Independent Systems, they became a part of the Separatist Droid Army. B1s would be the Confederacy's most common soldiers, with quintillions churned out on countless CIS factory worlds. They participated in many battles including, but not limited to, the Battle of Geonosis, Battle of Muunilinst, Second Battle of Coruscant, and Battle of Kashyyyk.

Following the execution of the Separatist Council by Darth Sidious's new apprentice, Darth Vader, all, if not most, of the B1s were de-activated. However, some would be re-activated to serve in the various Confederate Remnants.

During the Galactic Civil War, B1s left over from the Clone Wars were discovered on Geonosis by Rebel pilot Wedge Antilles after crash landing in his X-wing. Several stormtroopers that landed on the planet in escape pods managed to destroy many droids by using E-Web blasters.
