With her own body

She decided to make a gamble. She used up almost all of her powers to form his perfect desirable body. One that would hopefully break through that mental block he made himself. Only, it wasn't what most would call "sexy", attractive sure but it was rather plain. She wasn't big, or curvy, or thin just right in the middle.

However while her physical appearance may be rather plain she could feel her mental state change immensely. She smiled softly as she didn't fight the changes, rather she embraced them, encouraged them to take over her. She wanted this, to become his perfect servant and that's what was happening. Now all she needed to do was find a way to get him to open up, but how was her biggest question.
