9'β

9'β (ナインベータ) is a character in DARLING in the FRANXX. He was a Parasite who served in the 9's, a special forces unit that APE directly controls. He was partnered with 9'η and piloted a FRANXX called 9 Model.

Appearance
Nine Beta has light blue hair with grey eyes. He wears a special Parasite uniform emblazoned with white and gold, instead of the typical gray uniforms that other Parasite squads use. When in his FRANXX, Beta, along with the others in his squad, sports a red battle suit. Like his fellow stamens, he appears with golden horns that appear to be holographic klaxosaur horns.

Personality
Nine Beta often does not say much and lets his team leader 9'α speak on behalf of the 9's squad.

In Episode 17, Nine Beta is shown to be aware of his surroundings as he commented the ruined state of Mistilteinn was not a good place for parasites.

In Episode 22, Nine Beta is shown to be willing to fight to his death when he, along with Alpha and Gamma, offered to come with Squad 13 to fight the final battle against VIRM. This was further demonstrated when he and Gamma went on 'a blaze of glory' in Episode 23 to take out a huge number of VIRM soldiers, which he met his demise.

Episode 17: Eden
9'α, 9'β, 9'γ, 9'δ and 9'ε show up at Mistilteinn on Papa's orders. As 9'α explains that Papa hadn't forgotten Squad 13, much to their relief, 9'β whispers to 9'γ that the environment of Mistilteinn was not good for Squad 13. When offered bread by Zorome, 9'β politely declines. Later, 9'β and his squadmates examined the baby book 9'δ found when she bumped into Kokoro earlier and find it contains information that Papa has banned. At the end of the episode, 9'β and the rest of the 9's arrive at Cosmos by elevator. 9'α tells Papa there is something he needs to know.

Etymology
Similarly to Zero Two, he received the name from Papa. Beta is a letter in the Greek alphabet.
