The Provisional Evangelion Unit-05 which Mari pilots drastically differs from previous incarnations of the Eva Unit. It has four mechanical ”legs” that end in wheels and a lack of hands which is replaced with a jousting lance and “claw”. This unique design requires Mari to wear a helmet-like contraption in order to pilot Unit-05. Her plugsuit is also equipped with several attachments that connect to tubing that apparently help her in moving her unit.
So pretty! I really like her choice of setting for this photograph. Thanks to Quince for sending this!
