Incorruptible Pure Pureness/Video Games

You're really going to be glad when you play as, or work with, these characters in your games.

Terra Branford, of Final Fantasy VI. While she was mentally enslaved by the Empire and forced to do horrible things while being controlled, when she is freed she later becomes a pure hearted protector. She ends up caring for a group of orphans in Mobliz whose parents were murdered by Kefka after the Apocalypse. Once she finds out who she is, she becomes a protector, who fights not to kill, but to protect and to ensure hope. Completely driven by love, she never has hatred in her heart.
- Co-star Celes Chere is described as having a spirit as pure as snow, but she plays more of The Atoner as she has done past evil actions under free will due to being a general for the Empire. It can be said that she does fall under this trope later in the game, as the Empire tries to bring her back to their side on the Floating Island, but she refuses.
Aerith of Final Fantasy VII is probably the only person alive in the world who could get The Planet to condone a Holy, besides the fact that she's the only person alive with the means and knowledge of how to do so. Nevertheless it seems that this might have been common among the Cetra when there were a lot of them.
Link in The Legend of Zelda: A Link to The Past. His true form / inner animal is a pink bunny.
- The Links in general are described as having pure hearts. Combined with the Triforce of Courage, it's why only he/they can wield the Master Sword.
- In Twilight Princess he is forcibly transformed into a wolf. Even in this bestial form, various characters note that it hasn't diminished his nobility one bit.
  - Interestingly enough, those characters who DON'T freak out when they see Wolf Link are usually innocent characters themselves (Agitha the wide-eyed bug collector and the innocent simpleton lantern salesman at Faron, among others)
- Princess Zelda herself also qualifies; in the linked games of Oracle of Ages and Oracle of Seasons, she is specifically sought by the villain to be a human sacrifice for this precise reason.
The whole point of Ultima IV is for the main protagonist to become this.
The Princesses of the Heart from Kingdom Hearts (Alice, Jasmine, Snow White, Belle, Cinderella, Aurora and Kairi) are, by definition, seven maidens of Incorruptible Pure Pureness. In Birth by Sleep, several characters observe that Ventus's heart is similar to theirs - because his corruptible impureness was removed and molded into Vanitas a few years earlier.
- Both Sora and Mickey. Mickey is associated with light, after all.
- Aqua, being the only keybearer of the BBS Power Trio to achieve the rank of Keyblade Master. Her purity isn't quite as much a part of her character as it is with Ventus or Sora, but it was still sufficient to allow her to survive for more than a decade in the Realm of Darkness without her armor or her normal keyblade.
  - In addition Vanitas considered her a possible "backup" for Ventus, should the latter not become strong enough to join with him. Which means that her heart is, or can become, pure enough to be considered "pure light"
Adell from Disgaea 2, at least by the standards of the Disgaea universe.
- Artina from Disgaea 4 is definitely this. She was a nurse who aided enemy soldiers during a war, unwilling to let anyone die if she could prevent it. When she encountered the vampire Valvatorez, she willingly offered him her neck rather than have him feed on someone else. When she was eventually executed for the "aiding the enemy" thing, she became an angel in Celestia (implied to be an extremely rare occurrence in this Crapsack World).
  - In a weird way, Valvatorez himself becomes this thanks to her. He was a bloody tyrant, and so offended when Artina expressed no fear that he swore he would drink no blood until he showed her true terror. His failure to take this promise seriously led to her death (he was supposed to protect her, because he needed her alive to scare her). Remorseful, he keeps his promise and abstains from blood for 400 years. In the process he lost all his power, and is now a lowly Prinny instructor. He is now completely determined to keep any promises he makes at all costs. He also cares for the Prinnies (who are the butt monkeys of the universe), and enacts a Netherworld-wide campaign of reform to protect them.
Nanako Dojima of Persona 4, perhaps by virtue of being 7 years old, loves everyone unconditionally and sincerely. The only person not to manifest a Shadow when thrown into the TV world, though whether it's because she's that pure or because she's too young to have fully manifested her ego is unknown.
Imoen does take a turn for the morbid at times, but her genuine cheer and goodness was, apparently, enough to keep the piece of the God of Murder inside her at bay.
Princess Peach, especially in the RPG games. In the first Paper Mario game, her love for her kingdom is enough to counter Bowser's defensive spell, and in the second one her purity is what makes her the chosen vessel for the Shadow Queen. Also present is Luigi. The Partners In Time' Aurora Block shows exactly how pure his heart is...which results in the Aurora Block humorously crushing him. This isn't exactly the case with his paper counterpart, though his arrogant personality is played for laughs.
The eight potential player characters in Darkstone are known as the Pure of Heart, a group of special fighters whose souls cannot be tainted by evil.
Earthbound gives us a lot of examples. From MOTHER 1, you have Ana (one of the party members) and Queen Maria. Then, in Earthbound, you have Paula Polestar, the second playable character. In the next game, you get Hinawa, the mother of Lucas and Claus.
Banjo from the Banjo-Kazooie series is pretty much the nicest bear that you'll ever meet. Basically, he's as sweet as honey, which he eats. Not so much with Kazooie who is more of a snarker, though she is truly a good person at heart.
Runescape has Armadyl, the god of justice. He is the one god that wishes for all the other gods to live in peace and coexist. This is subverted with Saradomin...while his worshippers would likely portray him as such, it is eventually revealed that Saradomin wasn't always the benevolent god that he is today and he is somewhat of an atoner.
Marth and his love interest Caeda were portrayed like this in Fire Emblem Shadow Dragon, and especially Mystery of the Emblem. He pretty much was fair to everybody and was always innocent minded despite the evil things that happened to and around them.
Beatrice from ~Dante's Inferno~.
Paz from Metal Gear Solid Peace Walker is a subversion, since she's really a nihilistic mole for The Patriots and was just using the Incorruptible Pure Pureness personality as a cover.
Colette Brunel from Tales of Symphonia combines this with Love Freak and The Ditz. Of course, her counterpart in the alternate world Zelos, is anything but.
Byakuren Hijiri of Touhou is probably a Deconstruction of this trope. Sure, she's like Mahatma Gandhi and Martin Luther King Jr. combined, but even ZUN questions whether her equality paradigm makes a lick of sense in Gensoukyou, where humans are basically at the mercy of the youkai that outnumber and outpower them.
- Definitely Deconstructed with Hinanawi Tenshi. She's a celestial, and a celestial is supposed to be this trope incarnate; it's even a requirement to be a celestial to begin with. But she sure doesn't live up to it...
- Kasen Ibara strives to be this trope incarnate, with mixed results. One hand missing notwithstanding...
  - Hermits must follow the training of Shuugyou (abandoning worldly desires to pursue enlightenment) in order to preserve their existence. It is far more difficult than being a celestial, as they must be diligent in their training lest an assassin from Hell comes every century to kill them as their powers weaken when they stray or they will even turn to ash. The Touhou universe is more lenient with them.
Hatou Yumei in the Girls Love Visual Novel Akai Ito. Listing the many, many reasons why she's this trope will take too long.
How about an entire species of Incorruptible Pure Pureness then? I'm talking about the Pokémon Absol. They watch humanity from their mountain dwellings only to warn us disasters both natural and man made. And what do we do to repay them? The human villagers falsely and mistakenly accuse them of causing these disasters then persecute and abuse them. Yet they still warn us in hope that one day we'll finally pay attention and heed their warnings. If that's not Incorruptible Pure Pureness I don't know what is.
In Fate/stay night, Gilgamesh is this. Gilgamesh reveals he managed to stop all the evils of the world corrupting him when he was hit by the Holy Grail's curse via his willpower and purity. Fate!Shirou manages to be this, surviving the same curse by will alone once, then using Avalon to block it when it hit him a second time.
Amberle in the Elder Wars of Lusternia. Sadly, she didn't realize she was in a Cosmic Horror Story - while attempting to reach out to a Soulless God, she was murdered and devoured whole, providing Elder War protagonist Meridian with a Dead Little Sister.
Jun Kazama from the Tekken series. It may be such an incredible level of purity that even becoming Unknown hasn't eliminated it.
Even if she was manipulated by Iris and later ends up being Right for the Wrong Reasons and gets her own Heroic BSOD upon being attacked and badly wounded by Iris, Tia of Rosenkreuzstilette is shown to be this, seeing how she not only refuses to take part in RKS's rebellion but also condemns it, and is willing to protect the people of RKS as much as she's willing to protect the people from RKS, that without letting anybody be sacrificed. She seems not to have a slight inch of hatred in her heart, despite refusing to forgive Iris for using everybody to attack one another for her own amusement. It's later revealed that Tia was reincarnated from another form of Incorruptible Pure Pureness in the form of Rosenkreuz, born with his greatest ability of all; the ability to tap into the strength of others'. It's no wonder Iris recognizes her as his other incarnation besides herself, the "Blade of Rosenkreuz".
While he does tend to be quite an Idiot Hero of a Cloudcuckoolander, Kirby is revealed to be this in Kirby Mass Attack. Reason? He has the Heroic Heart, which resembles a star, that got separated from his main body when Kirby was split into ten and almost wiped out of existence by Complete Monster Necrodeus. Even after he was split, his heroic heart remains, and offers for itself and the ten Kirbys to fight Necrodeus together.
Pit from Kid Icarus: Uprising have shown themselves to be this. The best example is the Mirror of Truth, which is supposed to reflect the dark side of someone who looks into it. Pandora tricked Pit into breaking it and creating Dark Pit, Virdini says that the Chaos Kin only feeds on the purest of souls and the Chaos Kin idol states that Dark Pit was needed to be revived.

AA species of Incorruptible Pure Pureness: the Pokémon Absol. They watch humanity from their mountain dwellings only to warn us of disasters both natural and man-made. And what do we do to repay them? The human villagers falsely and mistakenly accuse them of causing these disasters then persecute and abuse them. Yet they still warn us in hope that one day we'll finally pay attention and heed their warnings. And even then, as revealed in Pokémon Sun and Moon, younger generations have started to listen.Gardevoir is very protective of its Trainer and if needed will risk its own life or create a small black hole that prevents harm before the black hole ceases to exist shortly after; this however causes Gardevoir to lose all of it's psychic power for a undetermined amount of time. Due to Gardevoir's impressive psychic power, they can also see into the future, can make it to where they don't feel the force of gravity and ultimately distort dimensions if needed.
