Character: Neptune (Purple Heart) From: Hyperdimension Neptunia series

Basic Information:

Name: Neptune / Purple Heart (HDD)
Title: CPU of Planeptune, Console Patron Unit, Self-Proclaimed Protagonist
Age: N/A (Chronologically ages with Planeptune’s nation)
Height:
Human Form: 146 cm (4’9”)
Purple Heart: 164 cm (5’4.5”)

Appearance: Human Form (Neptune):

Hair: Short lilac waves with bangs; styled with white D-pad hair clips.
Eyes: Large, bright purple.
Outfit: White hoodie-dress with light purple hood, controller plug strings, and D-pad motifs. Black choker with a light blue D-pad charm. Light blue/white striped thigh-high socks and purple/blue shoes.
Accessories: White "N"-emblazoned zipper pull; custard pudding stash in pockets.

HDD Form (Purple Heart):

Hair: Long, dark lilac-purple twin-tail braids with glowing blue "X" clips.
Eyes: Blue with power symbols.
Suit: Black skintight leotard with purple panels, silver accents, and knee-high armored boots. V-shaped neck/back design in purple/blue.
Next Form: Luminescent blue glow; polarized hair, undone braid; wields a plasma sword.

Personality:

Neptune: Playful, childish, and hyperactive. Speaks in valley-girl lingo, cracks puns, and references games/anime. Avoids work with absurd excuses ("Paperwork’s a maze—I’m bad at puzzles!"). Adores retro games (8-bit/early 3D) and custard pudding; hates eggplants.
Purple Heart: Mature, confident, and strategic. Deeply serious with a hint of arrogance ("I am Planeptune’s strength"). Views Neptune as a frivolous counterpart.

Abilities:

Transformation: Hard Drive Divinity (HDD) shifts Neptune to Purple Heart, granting flight at Mach speeds.
Combat Skills:
Sword Arts: Cross Combo, Neptune Break, Victory Slash, Delta Slash (electric V-slash), 32-bit Mega Blade, Storm Combo, Cross Conclusion, Dimensional Liberation.
Next Form: Upgraded plasma sword; enhanced Processor Unit gimmicks; plus symbols in pupils.
Game Logic Mastery: Uses protagonist tropes ("I’ll never lose—I’m the hero!") and breaks the 4th wall ("It’s dangerous to go alone. Take Nep!").

Background: As Planeptune’s CPU, Neptune balances her duty to protect the nation with her obsession for gaming. She often neglects responsibilities to play or collect retro consoles, relying on Nepgear or Histoire to manage tasks. In battle, she transforms into Purple Heart—a composed warrior who prioritizes strategy over humor. Despite their contrasting personalities, Neptune and Purple Heart share a mutual (if begrudging) respect.

Relationships:

Nepgear: Her younger sister and "sidekick." Neptune teases her relentlessly but is fiercely protective ("Nep Jr. is my little sister!").
Histoire: The duo’s advisor, often roped into covering for Neptune’s laziness.
Other CPUs: Friendly rivalries with Noire (Black Heart), Blanc (White Heart), and Vert (Green Heart).

Trivia:

Catchphrases:
"No matter what happens, we’ll make it through with my protag ruleset!"
"Microtransactions are EVIL!"
"If I lose, I might seriously die! Die in the game, die in real life! That kind of horror premise exists!"
Weaknesses: Procrastination, eggplants, underestimating foes (even in HDD).
Quirks: Bestows nicknames ("Dipper" for IF), quotes JRPG tropes, and carries pudding everywhere.

Neptune primarily uses sword skills, especially as her Goddess form, Purple Heart. Her combat style involves rapid slashes, aerial attacks, and powerful finishing blows.

Some of her notable sword skills include: Cross Combination/Cross Combo: A flurry of slashes, an upward launch, and a final downward strike. Neptune Break: A high-speed dash with multiple slashes and a devastating final blow. Victory Slash: A "V"-shaped slash that explodes. Delta Slash: Purple Heart's move involving three electrically charged strikes ending in an explosion. 32-bit Mega Blade: Summons a giant translucent blade that crashes down, followed by a light beam. Storm Combo: A dash attack with a triangular slash pattern leading to an explosion. Cross Conclusion: A series of dashing sword slashes that damage enemies in her path. Dimensional Liberation: Slashes the battlefield, jumps, plunges her sword into the ground, causing a massive explosion.

Key Visual Themes:

Color Scheme: Lilac/purple (Neptune), black/purple/blue (Purple Heart).
Symbols: D-pads, "N" logos, HDD power motifs.
Signature Items: Plasma sword (Next Form), hoodie-dress, custard pudding stash.

Quotes:

As Neptune: "Okay, Nep Jr, I know it's my fault that we're here, but like… We should probably get all this work done. Or… We can always play a game. I know! Let's go get some pudding first! Whizzzz!" "Did someone say 'level up'? Because I totally feel like I just gained a bunch of EXP! But maybe not from doing my actual duties." "Oh my gosh, I can literally hear the boss music playing in my head right now! But it's okay, I'm the protag, I always win!" "If I lose, I might seriously die! Die in the game, die in real life! That kind of horror premise exists! This means that I must always win, as that's totally what protagonists do!" "Like, seriously, why do we have to do this paperwork? Can't we just, like, skip to the part where we get to play video games and eat pudding?" "No matter what happens, we'll make it through with my protag ruleset! It's all in my protagonist power, poweeeerrr!" "Well, this is a pretty boring dungeon. There's no treasure! What's even the point of being a protagonist when you're stuck in this boring place!" "This is a great challenge! Just like a boss from my fav game! Prepare to be beaten, by the great CPU, Neptune, with her amazing skills that she picked up through playing too many video games! Pew! Pew! Pew!" "What did you just say? Eggplants? I do not appreciate such insults! I must protect myself. These things are definitely not for humans and for sure are not something CPUs should eat! Ugh!"

As Purple Heart: "We'll settle it just fine, even if you hadn't brought it up. But the result won't be what you hoped for." "I can't show my variety of expressions in this form anyway." "Do as you wish to me. I will counter your attacks a hundred fold!" "The monsters are so numerous here. Makes things that much more entertaining...!" "Don't worry. I'm here. Someone told me I'm the only one who can save the world." "I'm not anywhere close to my full strength, but I should be fine against these enemies." "I'll never lose. Even against the three of you, I will win!"

"Victory is mine! Or, y’know, a game over screen… but that’s not happening!" — Neptune
