Mbryo: The blurry distortion effect of an A.T. Field can be seen as Unit 01 integrates Zeruel's flesh into her own body and shapes it into an arm identical to her old one, leading to the implication that Angels and Evangelions are capable of using their A.T. Fields to define their physical appearance. This is consistent with Episode 10, where the same blur can be seen as Sandalphon morphs from his vaguely fetus-looking form to his completely disparate adult form.
