“Each Eva has its own designated pilot, and operates by synchronizing the pilot’s soul and the human soul inside the Eva via the enigmatic liquid substance known as LCL. Surrounded by LCL, the pilot’s nervous system, mind and body join with the Eva’s controls, allowing the Eva to be controlled by the pilot’s thoughts and actions. The higher a pilot’s synchronization ratio, the better the pilot can control the Eva and fight more adeptly.

“…the extent to which the Evas are biological is not immediately apparent.”
