Traits

Droid Chassis

You are a droid — a nonliving construct. You have no Constitution score, no connection to the Force, and cannot benefit from biological healing such as medpacs. You do not eat, sleep, or breathe; downtime is spent in maintenance cycles. You are immune to mind-affecting effects (Charm, Fear), poison, and disease, and you ignore vacuum, radiation, and noncorrosive atmospheric hazards. Stun weapons — and other effects that work only on a living nervous system — fail against you, but Ion is the chassis analogue and can still disrupt you. (See §13 Droids.)

Squad Tactics

B1s in formation, never alone. When one or more allies are within 5 ft of the target you are attacking, you gain +1 to attack rolls against that target.

Programmed Drill

Every B1 ships with manufacturer-trained blaster-rifle muscle-memory; the E-5 was your canonical sidearm. You are proficient with the Blaster Rifle.

Clumsy Servos

Whenever you roll a natural 1 on a melee attack roll, the wild swing creates a small accident. Roll 1d6 on the B1 Clumsiness Table: (1) Drop weapon — your weapon slips from your hand and lands in an unoccupied square within 5 ft (random direction); it takes an Object Interaction to retrieve. (2) Stumble — you over-rotate and fall prone in your current square. (3) Wrong target — your wild swing finds the nearest creature (friend or foe) within 5 ft of you instead; that creature takes 1d4 damage of the same type as your weapon (no attack roll). (4) Vocal slip [positive] — you blurt out a startled B1-ism ("Roger, roger!" or "Uh, what was the order?"); the absurdity throws the target off and they have Disadvantage on their next attack roll against you. (5) Wild distraction [positive] — your flailing genuinely confuses the target; one ally adjacent to your target gains Advantage on their next attack roll against that target. (6) Accidental trip [positive] — your over-rotated swing sweeps the target's footing; the target falls prone.

Ion Sensitivity

B1 chassis are notoriously easy to ion-knock-down. On Ion damage: failed STR save (DC = 8 + PB + STR mod) = Stunned until end of your next turn.

Vocal Folly

Your unmistakable B1 vocalizer ("Roger, roger!") makes voice-disguise nearly impossible. You have Disadvantage on Deception checks.

Lore

The B1 battle droid is a mass-produced infantry droid built for the Separatist army, the disposable foot soldier that made up the bulk of the Confederacy war machine during the Clone Wars. Spindly tan skeletons barely more than exposed struts and servos, B1s poured out of Multi-Troop Transports by the billion on Naboo, Geonosis, and a hundred other worlds. Individually they were almost useless, mocked by the very clones they fought for their clumsy aim and worse judgment, and their thin nasal drone of Roger, roger became the unofficial epitaph of the whole army. Collectively, though, they were a flood the Republic spent three years drowning in.

The B1's silhouette is unmistakable: a gangly humanoid roughly 1.93 meters tall, all exposed struts and servos, with a narrow elongated head and a long stalk of a neck that gives it a permanently startled, almost avian look. That body was built to fold. When deactivated or low on power, a B1 collapses into a flat compact bundle, knees and elbows tucking in and the long neck folding down last, so that more than a hundred of them could be racked inside a single transport. On activation the sequence reverses, limbs snapping open first and the head rising last. The frame is cheap, light, and lightly armored, which is the whole point. The droid's distinctive build deliberately echoes the Geonosian species that designed it.

That resemblance is no accident. The B1 was designed and first mass-produced by the Geonosians of Geonosis, churned out of their cavernous droid foundries, with the Baktoid lineage (Baktoid Armor Workshop and Baktoid Combat Automata) commissioned by the Trade Federation to put the design into industrial production. The humanoid layout was a cost decision rather than a tactical one: a two-armed, two-legged droid could grip existing rifles, sit in existing cockpits, and operate machinery built for organic soldiers, sparing the Federation from redesigning its entire arsenal. The result was a soldier you could stamp out by the assembly line and feed into a meat grinder without flinching, because there was no meat in it.

Early B1s were a hive mind with a fatal flaw. Rather than think for themselves, they took commands from a Central Control Computer aboard an orbiting Droid Control Ship, which let Neimoidian officers puppet an entire invasion by remote signal. The weakness showed at Naboo: when a young Anakin Skywalker blundered into the control ship and blew its reactor, every B1 on the surface froze mid-stride into standby hibernation, and the occupation collapsed in an instant. The Confederacy learned the lesson, and the reworked Clone Wars B1s carried their own (limited) onboard processing so they no longer dropped dead if a single ship was lost. Color-coded OOM command variants in yellow gave them officers; red security and blue pilot droids filled out the ranks. That independent processing is also what produced the franchise's most beloved bug: the personality glitches, the fear and confusion and bickering, the deadpan "Roger, roger" that made a faceless killing machine weirdly endearing.

The B1's story ends as abruptly as it ran at Naboo, only galaxy-wide. With the Separatist Council dead on Mustafar at Darth Vader's hand, a single shutdown signal raced out to the fleet and switched off the droid army en masse, and the Confederacy effectively ceased to exist overnight. A few pockets fought on: holdouts like Gizor Dellso's remnant reactivated and reprogrammed survivors, and on Agamar the tactical droid Kalani blocked the deactivation order outright, keeping his B1s marching for years after the war they were built for had ended. The droid that defined the Clone Wars was, fittingly, undone by the same single point of failure that doomed it at the start.

In SWURPG, a B1 plays exactly as that battlefield reputation suggests: never the lone hero, always better in a pack. Droid Chassis defines what it is (no breathing, no eating, no sleeping, immune to a host of biological miseries), while Squad Tactics and Programmed Drill reward fighting alongside allies and leaning on baked-in routines rather than improvisation. The mechanical penalties are honest about the model's reputation, too: a -2 to Strength and the Clumsy Servos trait capture the flimsy, poorly balanced frame, while a -2 to Wisdom and the infamous Vocal Folly trait model the dim, blurt-it-out-loud processing that made B1s such poor sentries. Ion Sensitivity leaves them especially vulnerable to the weapons designed to kill machines, and only a modest +1 to Dexterity and Perception proficiency hint at any competence. Play one for the comedy of a squad of expendable mooks, or for the surprisingly poignant angle of a single B1 that woke up after the shutdown signal and decided, against its programming, to keep going.

Physical Description

B1 chassis are skeletal humanoid frames roughly 1.9m tall — long thin limbs, a central torso spine, and a distinctive elongated cranial unit with a triangular photoreceptor cluster that gives the species their slightly puzzled appearance. Stock plating is cream or tan duraplast (the famous "droid yellow"); variant production runs included grey (security), red (officer/OOM), white (cold-weather), and tan-with-blue-trim (Trade Federation original livery). The whole frame is built for cheap mass production — joints are exposed, central servos are unarmored, and a single well-placed blaster bolt can sever the spine. Repair is straightforward (a B1 is mostly modular parts) but the chassis was never intended to outlast its first deployment.

Famous B1 Battle Droid Characters

R0-GR ("Roger")Reformed Separatist droid

R0-GR, who everyone just calls Roger, is a B1 battle droid who lived through the Clone Wars and kept right on going, eventually attaching himself to the Freemaker family of scavengers in LEGO Star Wars: The Freemaker Adventures. Where most B1s are interchangeable cannon fodder, Roger developed a lasting personality, trading blaster drills for life as a wisecracking mechanic and even ghost-writing his own memoirs. He is the most fully realized individual B1 in current canon, credited as the author of the in-universe reference book Droidography.

OOM-9Droid army field commander

OOM-9 led the Trade Federation's ground forces during the invasion of Naboo in The Phantom Menace, directing the push against the Gungan army and the occupation of Theed. He is technically an OOM-series command unit built on the same B1 chassis, marked out from the rank and file by his yellow officer coloring. He remains the best-known named commander of the B1 line.
