FRANXX

FRANXX are robot weapons created by Dr. FRANXX to combat Klaxosaurs, usually piloted by children in boy-girl pairs. Those who can pilot FRANXX are called Parasites.

All FRANXX units are at the disposal of APE, the government body of this world.

The FRANXXs feature certain similarities to the flowers after which they were named.

FRANXX
In order for the Parasites to connect with their FRANXX, each pilot has to first undress, put on a special underwear, and then change into a suit. The Pistil takes over the FRANXX. Every damage the FRANXX gets will be shared with the Pistil. When the paracapacity is low, only the female seems to get exhausted while the Stamen does not feel the stress. Therefore, they need to communicate verbally. Moreover, the Parasites connect their "minds" or to some sort of extrasensory level. The surrounding environment and the faces of the participants in the communication can be projected on the walls.

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. The 9's have custom made FRANXX units. The facial expression of the FRANXX captures the emotion of the Pistil including happy, angry, exciting and sad.

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. Below are the names of the current Pistils and Stamen of Plantation 13.

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. This will negatively affect their health 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.
