"LCL is a yellow-tinted, translucent liquid used to mentally link a pilot with the Evangelion and supply oxygen directly to the lungs when breathed, similar to liquid breathing. Its properties can be altered when it is electrically charged; this includes turning the liquid colorless. It may also help in protecting a pilot from mental attacks and physical shocks. LCL may also be compared to the amniotic fluid in the mother's womb; many of the mother references that the main character has in the story take place in LCL."
