Darling in the Franxx Episode 23 explanation

Many of you are wondering why Zero Two suddenly turned into stone and became a giant mecha waifu





The answer is quite simple really and the Klaxo-sapien Queen even explained it. This simply another form for the Klaxosaurs. The Klaxosaurs were stated to have transformed during their war with VIRM, some became the magma within the earth, others underwent a fusion with a biomechanical object, using two Klaoxsapiens, a male and female. The male becomes the source of power for the body, while the female seemingly merges with the body to control it. Obviously, the female must have abandoned their physical form to do this…just like Zero Two who turned to stone prior to the emergence of Apus Pure.





What we saw was not magic or anything that wasnt foreshadowed before in the series. Hiro and Zero Two simply became a Klaxosaur on a much larger scale due to the Apus was originally Star Entity, a massive Klaxosaur/biomechanical weapon.

Its unique appearance however must be due to the fact both of them are hybrids, since most examples of this sort of fusion resulted in feral and mindless foot soldiers





They both made the ultimate sacrifice to end the war.

So before you deride this sudden appearance of this beautiful machine, heed my words and look back, and you will see it was all leading up to this moment.
