Rebecca Crane

The Brotherhood's hardware genius, Rebecca built Baby — the Animus 2.0 — out of scavenged parts and outperformed Abstergo's billion-dollar program from the back of a van. She ran every session of the Desmond era, kept the cell moving through Italy one step ahead of Vidic, and later wired the Assassins into Abstergo Entertainment's own systems through the researcher they'd suborned. Field work found her too: she took a bullet meant for Shaun in the London Shroud raid and kept working through the recovery.
