001

 is a character in DARLING in the FRANXX.

Appearance
001, also known as the Princess of Klaxosaurs, is shown to have long flowing white hair with prominent blue eyes. She also seems to have large klaxosaur like thorns which she can control on her back.

Personality
So far, she is shown to despise Papa and the others, calling them “damned human wannabes”. She doesn't hesitate resorting to violence whenever she feels threatened (e.g. Episode 17, Tarsier's attempted murder of 001 near the end of the episode)

Episode 16: Days of Our Lives
In the new opening sequence, the Klaxosaur Princess briefly appears, possessing eight spiderlike appendages, bluish-white hair, blue eyes, a tiara, and a single blue horn.

In the episode, the Seven Sages (two of whom, it is quite worth mentioning, are absent) refer to her in passing. They discuss that their parasite reserves have dwindled down to just 60% in the month following the battle of Gran Crevasse. When one of them asks if perhaps they went too far by blowing up the plantations, Vice Chairman replies by saying taking a Machiavellian approach: "The ends justify the means. Humanity now has control of Gran Crevasse." He then goes on to say that the construction of Hringhorni, which appears to be a colossal ship or FranXX unit, is in its final phase, too. Papa then adds that he has sent two messengers (referring to the other two sages) to "you-know-where," saying that "this will likely be our final warning to them." The scene ends with him saying, "There is no need for two keys. Now, Klaxosaur Princess, which will you choose?"
