Amon/Female

"Okay. I am a woman...Somehow, this isn't bothering me as much as I initially thought. Maybe because my main concern now is the fact that I'm..." "Stark naked in an abandoned building's bathroom like some exhibitionist?" "...Not dignifying that."

- Amonko, after her first transformation, speaking to Gram

Amonko (アモンコ Amonko), also called Amy (エーミー Ēmī) are the names assigned to the female incarnation of Amon by Lamia, though she will still go by Amon. Amonko is not a distinct entity from Amon, unlike Beast, and is instead the result of a gender switch that occurred due to Eva Kiesler injecting Amon with an as-of-now unknown substance that alters the man's genetic make-up when exposed to Red Lacrima. Unlike Amon, who has powerful magical energy at his disposal, the exposure to Red Lacrima strips Amonko of her own magic, rendering her technically powerless with the exception of her Black Blood, which is more similar to a curse.

Amonko appears numerous times in Fairy Tail: Vice, whenever Amon is exposed to Red Lacrima; the change is only temporary, however, and Amonko reverts back to her original male incarnation when the energy of the Red Lacrima leaves her body. Surprisingly, Amonko does not particularly hold any dislike for the body, as she told Gram, and adapts fairly well to the new body despite being unfamiliar with it.
