Neptune (Hyperdimension Neptunia)

"I'm Neptune! I'm the CPU of Planeptune!"

- Neptune Neptune is the human form of Purple Heart, the CPU of Planeptune, and also the main protagonist in Hyperdimension Neptunia who loses her memory after a terrible fight and is banished to Gamindustri. After crash landing near nurse in training, Compa's house. Now she must try to rally the other Goddesses and fellow party members to come aid her in defeating the evil goddess, Arfoire.

Personality
Out of the four main Goddesses, Neptune is the most careless and carefree. She'll jump head first into any situation dangerous or not, and does not bother to think about the possible consequences that await her. Several characters (including her own friends) see Neptune as being downright stupid and somewhat insane, due to coming off clueless, airheaded, and with a tendency of asking random questions or getting shocking ideas and theories.

Besides that, Neptune is often surprised easily and has shown klutzy tendencies. She usually shows an eager and perky behavior and is very affectionate to generally anyone, to the point of giving them cute nicknames or refusing to give them their personal space. Such as tickling girls, hugging them, or even touching their breasts. Noire of whom, is usually her target.

She also happens to really love food. Often in the middle of a snack or thinking about food, more-so in the Manga and official artwork she can be seen eating every so often. She often receives comments from both friend and foe about her 'pudgy' physique.

At first, Neptune was uncaring for anything important and was very lazy and impatient. She soon learned however that it was important to protect everyone depending on them and made plenty of new friends.

In Mk2, Neptune is still an airhead and pretty childish. But she's lost her attitude and impatient behavior and seems a little more mature and caring, and a little less selfish. She cares deeply for her little sister and tries to help with her confidence issues, and also happens to be very protective over Nepgear.

In Victory, Neptune seems to be the same but she has become somewhat more rude and insensitive, and has picked up her lazy behavior again, showing that she's never quite gotten over being irresponsible yet.

In the manga adaptation, Neptune is still a friendly, touchy, happy girl whose love of food is a lot more apparent then in the game itself. She also is shown to be a very big pervert, such as near the end of the Christmas chapter when she began to picture a bondage themed Noire and gave her a funny expression until Noire caught her.

In the anime adaptation, her personality remains mostly the same, though she seems slightly less vacuous and tends to take situations, as well as her responsibilities, more seriously than her video game counterparts.

Purple Heart (HDD)
As Purple Heart, Neptune turns very serious and loses her ditzy attitude and friendly disposition at first. Showing a more confident, mature, prideful self instead. Unlike most, her voice noticeably deepens significantly. She loves a good fight and does not give up until winning. She feels superior to the rest, due to being the strongest in terms of sheer power, making a single hit damage up to 2000 points. While the others would have to power up just to make a special attack match that very amount.

Despite this, however, and due to her over-confidence, they teamed up against her and took her down with ease, acknowledging that she was the biggest threat out of the four of them. While she is much more calm and observant, Purple Heart happens to be full of herself at first and gloats how the others couldn't beat her even if all three tried at once. It was her pride and gloating that made her the victim of their termination. Over the course of the game, due to her memory loss, she lessens up on this harsh behavior.

In Mk2 and Victory, Purple Heart is much more level headed and less prideful now and still retains "Neptune" traits in herself. Such as riding a roller coaster despite causing a light panic. She trusts the other Goddesses more than in the first game and is more caring towards the others. When she is sent to the parallel dimension of Gamindustri, she takes on the role of leader and usually acts as the voice of reason when the other CPUs lose focus of the situation to indulge in their eccentricities and arguments.

Like her normal self, Purple Heart still has a bit of air-headed tendencies. Though, it is a far less prevalent trait of her personality when compared to her human self.

Appearance
Neptune is a light skinned girl with the body of a pre-teen and being one of the shortest Goddesses of the group. She has little to no breast, but she doesn't seem to care. Her eyes are light purple, almost the same shade as her hair, which is about shoulder length with messy bangs/side parts of hair framing her face reaching her shoulders, along with many strands sticking up. In her hair she wears two game-pad shaped hairclips.

Neptune's outfit consist of a white hoodie worn like a dress with two light blue stripes down her sleeves, lining the hood, and down the center with a big white circled zipper with a purple N on it. The hood and ends of her sleeves are purple, while they also consist of two lilac purple stripes. For the hood, her jacket has two plug shaped straps and big pockets with X shapes on them with purple coloring. Along with a plain white choker, knee length white and blue striped panty-hose/stockings, and lilac with blue and white accent shoes.

Rarely shown are her undergarments, which are typical shimapan (striped undergarments) that are light blue and white.

As Purple Heart, her hair becomes a dark lilac-purple while her eyes turn blue. Her hair becomes very long and is worn in twintail braids while her bangs and the hair that frame her face are somewhat longer. Her hairclips turn into small black circular pieces with glowing blue x's on them. Her figure is more mature/curvier, only losing out to Vert/Green Heart (and in Neptunia V, Iris Heart and Yellow Heart) Purple Heart's suit resembles a black skin suit with purple segments and silver pieces along it. The boots/leg armor is above the knee.

Neptune can also turn herself into a ship that has a similar color scheme.

In Hyperdimension Neptunia V, Neptune changes her normal attire while her HDD form stays mostly the same save for an seeming increase in bust size or bust emphasis.

Neptune's new attire looks like a summer variety of her previous outfit. Instead of a big sweater/hoodie-dress, she wears a deep purple dress with lilac lining along the bottom, center, top, and pockets, along with white spiked edging at the hem. She wears a white, short-jacket over this with a big N button, purple plug-like strings, and purple lining and buckles on each shoulder sleeve. Her choker remains the same, along with her socks and shoes. On her wrist she has white bracelets with a soft spiked material and small powder blue spots in the center.

Weapons and Abilities
In battle, Neptune is a well-rounded character who relies on power. Though not as fast as her sister, she has higher attack power. She is at best when paired up with Nepgear due to their combo attack being one of the strongest in the game.

Her defensive stats are quite balanced as well and she has one of the highest HP's in the game. If you decide not toput Nepgear in your party, then Neptune is the best replacement.
