Golden Body

Quirk
Golden Body (ゴールデンボディ): Aiko's Quirk is able to mimic the properties of gold, effectively causing her to appear as if made of gold. She shows no loss of flexibility from her ability as she was able to move her arms around with ease as well as brush her hair. She has also shown that she is able to return her body to its natural self.

While in the armored state, Aiko possesses the same degree of mobility that he does in her normal form, though her endurance and speed are enhanced. The conversion from flesh and bone to organic gold is accomplished by a psionic whole-brain interface with an ionic form of osmium, an extremely dense metal, located in another dimension. In willing the act of transformation, Aiko actually exchanges osmium atoms for her carbon atoms. The psionic interface with the other dimension re-creates all of Aiko's body in functionally similar organic ionic-osmium materials.

The process by which Aiko gains additional mass from an unknown, perhaps extra-dimensional, force remains unknown. Aiko cannot become partially or selectively armored; her body is either entirely converted or not.
