- Not to be confused with Neptune/Nepbike
Neptune is the human form of the CPU Purple Heart. She is often considered to be energetic and dorky. Her favorite food is custard pudding and she loves playing video games. While she enjoys playing all games, she especially loves Retro video games.
Neptune has short lilac hair with bangs that reach down to her collar bone and purple eyes. In her hair she wears white hair-clips in the shape of D-pads and around her neck is a choker that has a light blue D-pad symbol on it. She wears a mostly white hoodie dress that has a light purple hood, strings that look like controller plugs, and two huge purple and white pockets with purple D-Pad symbols on them. The sleeves have two light blue strips going all the way down while the front of the hoodie only contains one. The ends of the sleeves and the bottom of the hoodie have dark and light purple stripes. The zipper emblem and the back of the hoodie has a purple letter "N" to represent the first symbol of her name. She wears light blue and white striped thigh high socks with frills at the tops and her shoes are purple and blue.
She is a happy, excitable girl with a very strong sense of justice. Her ditzy personality causes her to be very careless at times which can either help her or land her into serious trouble. She makes friends rather easily due to her friendly nature and often gives them cute nicknames. People admire her optimistic outlook and confidence. She never gives up or backs down when the going gets tough and she makes sure to see her objective through to the very end. Neptune does not like fighting and is rather pacifistic, prefering to avoid conflicts whenever possible. But when she has to fight, she can act seriously.
Purple Heart is the goddess form of Neptune. She is considered to be cool, collected, just, and overall much more mature in comparison to her human form. While the personality and appearance change is major between the two forms, she still retains some aspects of her human form albeit to a lesser extent.
Purple Heart's appearance in her Lost Purple Core is reminiscent of the Purple Core but with much more stylization and design. Her hair and hair clips remain the same while her bodysuit, while still black, has purple and blue lining all around the torso and arms. The middle of the torso has purple mesh, allowing a vague vertical view of her stomach. She also wears thigh high boots with octagon patterns on the side at the very top; one filled it with purple and another just a white outline.
Purple Heart is a serious and mature person. She's often calm and rarely changes facial expressions. She is a very observant and intelligent female, thinking in a rational matter most of the time. She is the complete opposite of her human form in many aspects but her strong sense of justice and confidence remains unchanged. It can be said that Purple Heart is a bit arrogant, having a strong confidence in her abilities and believing that no one can defeat her.
