9 Model

The  (, Kyuu Shiki) is a type of FRANXX specifically built for the 9's.

Appearance
The 9 Model is an intimidating-looking FRANXX with a sleek silhouette. It has large and bulky shoulder and leg plates. Their face is expressionless, as if they're wearing a mask. A blue glow illuminates from their eyes. Like many other FRANXX, they're armed with an orange lance. This FRANXX's design resembles that of Strelizia's, as its pistil, Zero Two, is a former member of the 9’s. The 9 Model (In the Manga, at least.) has remarkable speed and agility. Alpha’s 9 Model wears an eye patch over its right eye, as Alpha does due to having lost his right eye, and it also wears a trimmed cape.

The 9's are seen piloting the 9 Model at the battle of the Gran Crevasse. Ichigo remarks it's like having a bunch of Strelizias.

The 9's are seen piloting at the second battle of the Gran Crevasse.

Nine Delta's 9 Model FRANXX gets crushed by a VIRM soldier, killing Nine Delta and Nine Epsilon. Nine Alpha goes berserk and starts killing both VIRM soldiers and klaxosaurs.

Episode 23 : DARLING in the FRANXX
Nine Alpha and Hiro pilot in Nine Alpha's 9 Model to reach Zero Two during the galactic battle. Nine Beta and Nine Gamma join them in their respective 9 Models. During the galactic battle, Beta and Gamma went on 'a blaze of glory', destroying their 9 Models in the process.

Later on, Alpha helps Hiro reach Strelizia, but their 9 Model is surrounded by VIRM units. Alpha ejects Hiro out of the 9 Model into Strelizia. He tells him to say 'hi' to Iota (Zero Two) and self-destructs, taking the VIRM soldiers and the 9 Model with him.

Manga
Following the annihilation of the 9’s by the Klaxosaur Princess, the sole survivors, Alpha and Delta pair up to help Squad 13 in the siege of the Gran Crevasse. Dr. FRANXX immediately makes changes and amplifications to Alpha’s 9 Model, which was damaged from the battle against the Klaxosaur Princess.

Trivia
