Aridath battle droid

"Vrekon Shal, meet Aridath Battle Droids."

- Jur'ak D'aghar

Details
All the Aridath Battle Droids have different aspects; however, it is notable that each Droid is given the choice of what gender to be. Each Battle Droid is independant, and can choose names for themselves if they so choose. Most prefer to stay with their designations, however.

Type B (Behemoth)
"Made for defense. Good luck killing any."

- D'aghar

A large droid with minimal intelligence, this class of droid had thick armor. Used as a tank most of the time, it had a heavy projectile cannon protruding from the undercarriage. This cannon was able to swivel slowly in order to track larger targets if necessary, but was primarily used against enemy fortifications. Against enemy infantry the Type B had to rely on its massive claws that were on the ends of its feet. Reminiscent of a four-footed AT-TE, this 'Behemoth' type was primarily used for taking enemy fire. 5-meter (average) thick armor protected from all but the most powerful assaults, and a heavy shield generator could be projected in a sphere around it in order to protect allies. Defense was its main programming, and it was the best of the best in this regard.

Type A (Assassin)
"And, firing... Note, there is a small gap in armor between collarbone and neck. Did I get my polish messed up?"

- Assassin-18639

The 'Assassin' type A was actually the first model produced. Carrying a laser rifle in its hands, this droid was programmed to do damage. Tall and thin in appearance and sporting a dart shooter hidden in its left arm, it is reminiscent of the ancient IG-88 droids. Unusually accurate for an assassin droid (or even sentient sniper), it has an average kill rate of 19-1. A massive databank allows the droids to share important critical points in enemy armor instantaneously. This optimizes the number of instant kills. Interestingly, 76% of these droids chose 'female' programming over male, and some of them have requested modification in order to look better.

Type S (Soldier)
"Soldier Captain-4097 reporting. Pinned down under fire. Sticks and Red deactivated instantly. The station is lost, Commander. I'm sorry. I'm calling in a Broken Arrow. The men have voted, it's the only option. Bring the rain."

- Soldier Captain-4097, just before his death

The standard model of the Battle Droids, this slightly wider version of the Type A is the most successful of a long line of attempts at creating the Type S. Slightly more 'masculine' of a make, 51% of these were male. While perhaps less intelligent on average than the Type A, their personality cores are slightly more developed, allowing for a wider range of personalities among one type. With a powerful blaster rifle held in-hand, these heavy-to-medium-armored droids are by far the most versatile. Useful for everything from cover fire to simply blasting their way into an enemy base, this powerhouse of a droid is still unique among each model.

Type E (Engineer)
"Modeled after an R2-series droid I met once upon a time."

- D'aghar

With the most sophisticated personality cores, the Type E is not designed for front-line fighting. Far from it; this tool-covered droid resembles an ancient R2-series astromech. Speaking Binary instead of Galactic Basic most of the time by preference, these droids can't be stereotyped by anyone. The one thing that can be guaranteed similar from one to the next is that it'll be unique. Full of everything from basic tools to ridiculously specialized cutting mechanisms and interfaces, there are over thirty sections in each that are modifiable based on the droids' preferences.

History
Unseen until the Black Knight Crisis, the conflict was almost lost until D'aghar brought in the army of droids. Tearing through the Black Knight armies in a matter of months, the war was won entirely due to these droids.

Production
Production unknown, but D'aghar left the galaxy to get them.
