Neptune is the human form of the CPU Purple Heart and the former goddess of Planeptune. She is often considered to be energetic and dorky. Her favorite food is custard pudding and she loves playing video games. Eggplants are her most hated food, stating that they are not "people food". While she enjoys playing all games, she especially loves Retro video games. She likes to make video game references. Neptune 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. She can also summon a katana or a broadsword when she is in a fight. When Neptune went to the Ultra Dimension she lost her HDD form and couldn't turn into Purple Heart anymore. She spent years looking for a CPU Memory but never found one and ultimately began aging as a human. Since Neptune aged, some of Purple Heart's serious and mature personality traits became more prominent but in general Neptune is still her fun, ditzy self. By the time Neptune returned to her own dimension, her younger sister Nepgear had filled in as the goddess of Planeptune. As it turned out Neptune couldn't fulfill her role anymore and is now doing the boring stuff. Neptune was pretty bummed out that she wasn't the goddess anymore but had to be a helpful sister and guide Nepgear. With Neptune's new position, she has gotten lazier than usual and still gets nagged by Historie. Neptune has short lilac hair with bangs and purple eyes. She female and is 5'2 feet tall, slender, D cup breast size. She wears white hair-clips shaped like D-pads, a light blue choker with a D-pad symbol, and a mostly white hoodie dress featuring controller plug strings, large pockets with D-Pad symbols on them, light blue stripes on the sleeves, dark and light purple stripes at the ends of the sleeves and bottom of the hoodie. The zipper emblem has a purple "N" for her name. Her cleavage is slightly exposed. Neptune also wears light blue and white striped thigh high socks with frills at tops along with purple shoes combined with blue ones.
