FRANXX

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

FRANXX
The FRANXX used by Cerasus differ from typical FRANXX as they each have individual and unique designs befitting of their users. This is most likely because Plantation 13's Parasites are experiments. As shown in Episode 6, the other Plantations have identical FRANXX units, suiting their blank-slate personalities.

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.

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 is controlled by only its Pistil, it takes on a more beast-like appearance. Pistils appear to struggle heavily and injuries them significantly if continued for long periods of time.

This phenomenon is first shown with Strelizia. After 081 dies, Zero Two is forced to pilot alone, transforming it into its beast mode. When Mitsuru refuses to fight and Kokoro tries to pilot Genista alone, the lip of Genista's hat opens, revealing sharp metal "teeth" and two orange crosses appear above, making an animal-like face.

Paracapacity
Paracapacity (, Para Kyapashiti) is the numerical value indicating the degree of synchronization between FRANXX pilot and their FRANXX.
