FRANXX

FRANXX are robot weapons used to fight Klaxosaurs. Their creators are APE and drFRANXX. They feature a similarity to the flowers after which they were named.

Parasites
Parasites are those who pilot FRANXX. The female is known as the Pistil while the Stamen is the male. This is a direct reference to the male and female reproduction organs of flowers.

Stamen

 * APE: The government body.
 * Otona/kodomo: Evolved in this world. All children are called by codenames.
 * Klaxosaur: Generic name for the mysterious giant animals that threatens humanity.
 * Cerasus

Stampede Mode
Stampede mode (スタンピード・モード, Sutanpido Modo) occurs when a pilot loses control of his or her FRANXX. When a FRANXX was controlled by only its Pistil, the FRANXX took on a more beast-like appearance. In the case of Strelizia, it happened if its Stamen died.
