Carbon Costume

Murderbot (played by Alexander Skarsgard) is the titular security unit in Apple TV’s Murderbot.  It is also the narrator of The Murderbot Diaries book series, upon which the series is based.  Murderbot is assigned to protect the PreservationAux team including Pin-Lee and Dr. Gurathin.  In the series, Murderbot is shown as wearing white, black, and grey armor, with an asymmetrical helmet.  To create your costume, you can start with white and grey padded clothing for motorcycle riding.  Layer knee pads, chest armor, and forearm guards with gloves over that.  For the unique helmet, you can either purchase a black helmet and carefully add details with grey and white paint, or opt for a 3D printed mask instead.
