As Purple Heart, Neptune becomes very serious and loses her ditzy attitude and friendly disposition to show a more confident, prideful self. Unlike the other Goddesses, her voice noticeably deepens when she is Purple Heart.
She feels superior to the rest of the Goddesses, due to being the strongest physically, causing the others to team up against her.
After losing her memory, Purple Heart learns to be less full or herself and more humble.
In Hyperdimension Neptunia Mk2, Purple Heart has become level-headed and carries over many traits from Neptune into herself. She also trusts and cares for the other Goddess's and CPU Candidates more than ever.
