Threat File — Chaos Biker
TR 9 · Traitor AstartesSaves: Toughness +7, Agility +7
Proficiencies: Pilot +8, Awareness +5
Moving Target. Ranged attacks against the biker suffer Disadvantage in any round it moved 30 feet or more.
Mounted Fire Discipline. The biker may make its ranged attacks at any point along its movement, not just its endpoint.
Iron Skid. Once per scene, the biker negates being knocked from the bike or knocked Prone by an attack or hazard.
Bolter Strafe. The biker attacks up to two targets it passes within 30 feet of during its movement. Ranged Attack: +7 to hit, one attack per target. Hit: 2d8 + 3 ballistic damage.
Run Them Down. Melee Attack: +7 to hit, reach 5 ft., one target in the biker's path. Hit: 2d10 + 4 bludgeoning damage, and the target makes an Agility Save DC 15 or is knocked Prone and Exposed until the start of its next turn.
Circle the Kill. The biker moves up to its full Movement and ends behind an enemy's cover. That enemy gains no cover benefit against the biker until it moves.
Morale: Disengages at speed when outmatched; a biker that leaves is a biker that returns on the next objective.
Tactics: Never let it idle: it strafes, circles, and forces the party to keep rotating their facing while slower traitors advance. Terrain is its counter — give the party a chance to cut lanes, drop rubble, or mine the obvious circuit.
Loot / Evidence / Hooks: The bike survives its rider more often than not, and its corrupted machine-spirit will carry a new master exactly as far as it wants to.

GM ReferenceA Chaos Biker is a traitor Astartes on an armored machine that treats streets, dunes, and courtyards as fire lanes of its own. It brings bolter fire faster than the party can redeploy.
Use this enemy for pursuit scenes, convoy attacks, and open-ground encounters where the party's careful positioning needs to become a moving problem.
Very high speed, mounted bolter fire, ramming pressure, hard to pin, weaker when terrain kills its momentum.
