If this B-1 has ever been fitted with a restraining bolt, it doesn't seem to show it. This droids spouts more profanities and insults than the most ill-bred of mercenary captains, constantly issuing a sharp-tongued diatribe to any and all who have presented themselves as targets, or simply entered into its presence. The B-1 has a specific knack for scathing remarks concerning the parentage of its victims; although, in dual measure, a great deal of its verbal jabs actually present modicums of helpful advice, hidden beneath layers of seeming cruelty.

Sera's B-1, at the time of purchase, appears to have been blasted apart and reconstructed at least a dozen times over, if not more. No single one of its parts matches with the rest of its chassis; its main torso a dull, sandy red, likely destined for Geonosis, its limbs a mish-mash of various colors and components, while its head is bare steel, as if it had been pulled right off the assembly line before being flash-welded on. To add insult to injury, each piece bears varying degrees of battle damage, some brand new, others badly scarred. A few parts appear to have been fixed on with glue; how the thing still runs is anyone's guess.

It certainly won't be winning any beauty contests anytime soon... but, at least it has character.

Sometime before it came into Sera's possession, this B-1 appears to have been reprogrammed to act as a training droid, perhaps explaining the sheer degree of wear and tear present across its chassis. Whatever the case, the droid appears to have had its memory-module modified specifically for this purpose; it has a particular knack for remembering forms and patterns of combat that it has witnessed, and mimicking them later on. Although it lacks any real mastery, the multiplicity of fighting styles aids in the bot's teaching abilities; it is the perfect first opponent for any new trainee... with some degree of lethality held in reserve. Just in case.

Unfortunately, the droid's training programs and expanded memory make it... belligerent. Simply put, it has a tendency to pick fights; droids, people, animals. Anything that just so happens to test it, or challenge it in any sort of way, can expect a fight; all to improve the training regimen, of course.
