Yojimbo

A battered knight-class Assaultron with a horsehair plume, found running on bare minimum power in the Rapid City hospital (Session 4), her signature laser eye dark and broken until Ushi hands over a spare energy cell.

• Fights alongside the party once restored, eventually reaching full strength mid-fight and tearing into the Sentrybot alongside Zendaya.
• Helps the party finish assembling a genetic resequencer from parts scavenged during the hospital fight — the moment it's complete, a Harpy steals it from her hands.
• Explains her situation without dodging: she was contracted to retrieve exactly that kind of technology for something called the Ark; she doesn't know or particularly care what it's for, this is just the kind of work she and Ushi do — bounty hunting, fetch-quests, occasional bodyguard work.
• She defected from the Neon Queen Elizabeth's compound at The Observatory in the Black Hills, which is why the Queen's Knight, Sentrybot, Protectron, and Hydra unit were all sent after her specifically.
• Joins the party going forward at the players invitation.
