Aqua (Earth-101001)

Aqua (アクア) is one of the main protagonists of the anime series Kingdom Hearts. Aqua was a Keyblade wielder years before Sora was. Like Terra and Ventus, it is her dream to become a Keyblade Master, a dream she is the only one of the three to accomplish.

Appearance
Aqua has a tall and slender figure, about as thin as Ventus and standing a few inches shorter than Terra. She has blue eyes and medium-length icy blue hair, mostly parted to her left. She wears a black and navy blue, high-collared halter top, a black corset with two pairs of white laces, and black shorts. She has two pink straps intersecting over her chest, with a silver badge similar to badges also worn by Ven and Terra over the intersection. On Aqua's arms are white bell-sleeves and tan, fingerless gloves. She also wears a small, segmented piece of armor on each of her upper arms. She wears black stockings reaching about halfway up her thighs, leaving a small area of bare skin. There are two strips of blue cloth draped over each of her hips, along with a smaller, white strip of cloth tied around her waist and draped in the same manner. Her silver boots are pointed and armored, with a sharp "hook" on the outer side of each

Personality
She displays true elegance while fighting, and will do anything to protect her friends. When relaxed she can be very friendly and comedic, but when angered, she can become aggressive.

Aqua bears some similarities to Kairi and Sora, primarily in her sisterly affection for her closest friends. This is displayed by when she makes lucky charms for them, does everything in her power to protect Ventus (despite his apparent discouragement whenever she tells him to go home), her confidence that Terra will overcome the darkness, and when she strands herself in the Realm of Darkness in order to save him. Aqua is also shown to be very sociable with children, quickly befriending Kairi, Sora, and Riku. Aqua is remarkably calm and dead-set on her goals, and only threats on her loved ones seem to make her lose her composure. Although, like Sora, Aqua is comedically insecure in a romantic sense, so when Zack asks her out on a date, she shakes her head, wildly waves her arms, avoids eye contact, stutters, and blushes, desperately trying to compose herself. She also quickly changes the subject when Hercules asks why her face is red.

Aqua is typically modest, referring to herself as a trainee (only calling herself "Master Aqua" before she fights Terra-Xehanort, even then only as an intimidation tactic) and acting very respectful toward elders and authorities such as Master Eraqus, Queen Minnie and the Grand Councilwoman. However, like Eraqus, Aqua is also strict, stubborn, and overprotective, which sometimes makes her seem condescending.

Late teen years
Aqua, alongside Terra, was one of Eraqus's pupils. Like Terra, Aqua also had a dream of becoming a Keyblade master.

One day, a suspicious man named Master Xehanort arrived and gave Eraqus a new apprentice to work with, a boy named Ventus. Terra called out to Aqua and told her that a new apprentice had just arrived. Aqua and Terra tried to converse with Ven and asked him about why he wanted to train to become a Keyblade master. The questions troubled Ven to the point that he couldn't take the pressure. He fainted and shocked Aqua and Terra.

Eraqus told Aqua and Terra that the reason Ven fainted was because he had lost his memories. Aqua decided to look after Ven, in case he woke up. Many days passed and, despite Ven being unable to awaken, Aqua did not abandon him. One day, Aqua saw Ven open his eyes and regain consciousness. Overjoyed, she quickly informed a worried Terra and Master Eraqus.

Since that day, Aqua developed a very close relationship with Ventus, acting much like his older sister and becoming very protective of him. Over the years, Aqua, Terra, and Ven forged a strong bond with each other.

Kingdom Hearts Birth by Sleep
One night, Ven, Terra, and Aqua watch a meteor shower together. After commenting that Ven and Terra would make the weirdest brothers, Aqua gives them each a good luck charm called a Wayfinder she made herself, saving one for herself.

The next day, she takes the Mark of Mastery exam along with Terra, and becomes a Keyblade Master, although Terra fails due to his inability to control his darkness. After Terra and Ventus left, Aqua was the last apprentice to be sent by Eraqus to bring Ventus back to the Land of Departure. Before she left, Eraqus wanted to ask Aqua to keep an eye on Terra, to make sure he is alright and stays safe from the darkness in his heart. If Terra's heart would become too close to the darkness, Eraqus needed Aqua to bring Terra back immediately.

Aqua meets Terra in the Castle of Dreams, where she learns that Master Xehanort is looking for hearts of pure light, but she is comforted to hear that Terra had learned there that believing in a dream has the power to hold back the darkness. However, her faith in Terra is shaken when she arrives in Enchanted Dominion to learn that, according to Maleficent, Terra willingly helped steal Aurora's heart for her. Aqua later catches sight of Terra in the Lanes Between and pursues him to Radiant Garden, but loses track of him there.

Aqua meets Mickey Mouse and the young Princess of Heart, Kairi, who touched Aqua's Keyblade in fright, unintentionally performing a Bequeathing. Aqua and Mickey protect her from a group of Unversed, and in return, Kairi gives Aqua flowers, which becomes the Keyblade Destiny's Embrace. Aqua also places a protective charm on Kairi's necklace to help her in the future, believing that their meeting may not have been a coincidence. This charm would later transport Kairi to Destiny Islands where she would be with someone who would always protect her, while Ansem believed it was because Kairi, as a Princess, was naturally drawn to the Keybearer.

Aqua later meets up with Terra and Ventus, but the reunion is short-lived as they team up to battle a massive Unversed. They manage to defeat it, but things take a turn for the worse. Terra and Aqua begin to argue about Master Eraqus's orders, revealing to Terra that she was sent to watch him. Hurt by this, Terra leaves, and Ventus calls Aqua awful, claiming that she has let her new status as a Keyblade master go to her head. He then leaves to find Terra, as Aqua stays to contemplate.

After meeting Merlin at his house, Aqua goes to the town square and encounters the enigmatic Vanitas, who taunts her by inquiring about Ventus and if he has gotten stronger. When Aqua asks what he means, Vanitas attacks, and the pair fight a vicious battle. Aqua emerges victorious, but Vanitas simply leaves via Corridor of Darkness, making an ambiguous comment about her being his backup plan. Aqua then resolves to stop Vanitas to protect Ventus and Terra. Ventus then appears, asking to go with Aqua. At first, she is harsh with him and he appears discouraged. She softens and tells him she doesn't want to put him 'in harm's way', and departs not long after.

Aqua's faith in Terra is restored upon her visits to Olympus Coliseum and Deep Space. In Olympus Coliseum, Aqua learns that Hades attempted to trick Terra into being his warrior of darkness, but Terra instead saved Zack when Hades decided to use the warrior instead. In Deep Space, Aqua learns from Dr. Jumba that Terra considered his Wayfinder a precious reminder of their friendship, and had even inspired Experiment 626 to start making friends.

While in Neverland, Aqua encounters Peter Pan and the Lost Boys, joining them on their treasure hunt. They later find their treasure chest, filled with wooden swords and Ventus's wooden Keyblade. Peter Pan tells Aqua that Ventus left the toy there as he no longer needed it. Aqua then senses someone nearby and goes off to investigate. She then encounters Vanitas again, this time with Ventus's cherished Wooden Keyblade. The dark enigma cruelly mocks Aqua's actions and snaps the toy weapon in two. Greatly enraged by this, Aqua battles and defeats him again, but is left exhausted by the fight and passes out. While unconscious, she reminisces about the first starry night she spent with Terra and Ventus. She soon recovers and leaves Neverland.

At one point Aqua and Terra come to Destiny Islands and meet two young boys by the name of Sora and Riku. Aqua sees the strong bond between the two friends and advises Sora to help Riku if he ever falls into darkness; though she initially intends to grant Sora the power to use the Keyblade, she decides against it upon discovering that Terra had already done it for Riku, not wishing to put the two innocent children through the ordeals she and Terra have faced.

Aqua later encounters an unconscious Mickey drifting in space and takes him to the Mysterious Tower, where she hears of Eraqus's death from Yen Sid and heads to the Keyblade Graveyard to meet up with Terra and Ven.

A short conversation with Ventus takes place there, one where he states that if he does become the χ-blade, he wants the two of them to "put an end to me". Aqua appears horrified, but Master Xehanort makes an appearance and tells about the history of the Keyblade War. Afterwards they attack, and a great battle takes place. Xehanort holds Ven over the edge of a cliff where Aqua can see, he freezes the boy and drops him; however, she manages to catch him. After fighting Braig and then Ventus under Vanitas's influence, the X-blade is destroyed and she is flung into the Lanes Between, unconscious. Mickey finds her and Ventus drifting there and brings them both to Yen Sid's Tower, where it is revealed to her that Ventus has lost his heart. She takes Ven back to the Land of Departure and places his sleeping body in a throne. She takes Eraqus's Keyblade and transforms the world into Castle Oblivion to keep Ventus safe. Afterwards she says her goodbyes to Ven, fondly stroking his hair, and leaves. She then tracks down the possessed Terra to Radiant Garden.

Failing to bring Terra back to his senses, Aqua fights and defeats Xehanort; subsequently, Xehanort stabs himself in the chest with his own Keyblade in an attempt to lock Terra out as a horrified Aqua looks on. As Terra-Xehanort falls through a portal into the Realm of Darkness, Aqua dives in after him but quickly realizes that she will be unable to save them both. Instead, Aqua sacrifices her armor and Keyblade to save the dark being that had once been her dear friend, sending him back into the Realm of Light while she remains behind. Now stuck in the Realm of Darkness, Aqua is attacked by several giant Heartless and decides to just allow them to destroy her, but is saved by Terra and Ventus's Keyblades. She is then reminded of the people she is connected to. With renewed trust in her friends, Aqua looks at her Wayfinder.

Kingdom Hearts
Aqua's armor and Keyblade reside in the Chamber of Repose, a room constructed by Ansem's apprentices under Radiant Garden for an unknown purpose. Xemnas visits the armor often, calling it "friend" and talking to it for long periods of time.

Realizing that the Castle of Dreams has been swallowed by the darkness, Aqua roams the Realm of Darkness to uncover the source behind the strange occurrences. Furthermore, she also notices that time does not pass in the Realm of Darkness, and therefore does not know what is happening in the Realm of Light. In the remains of the Castle of Dreams, Aqua encounters an illusion of Terra. Realizing that the denizens of the world have not fallen to darkness, she resolves to press on. Arriving in the remains of Dwarf Woodlands, she encounters an illusion of Ventus and battles a phantom of herself inside the Magic Mirror. After breaking out of the Mirror, she pursues visions of Terra and Ventus in the remains of Enchanted Dominion, battling hordes of Darksides in the process. To her surprise, Terra speaks with her, explaining that he has become part of the darkness. Xehanort uses Terra's connections to Aqua to force her to reveal Ventus's location, but Terra battles Xehanort, forcing Xehanort to summon dark hands to drag Aqua further into the Realm of Darkness.

Aqua prepares to become one with the darkness, but she is rescued by King Mickey. After Mickey explains his mission to save the Realm of Light from the Heartless, the two locate the Kingdom Key D behind the door in the secret place in the remains of Destiny Islands. Aqua and Mickey realize they are on the opposite side of the Door to Darkness. Aqua and Mickey prepare to help Sora and Riku seal the Door to Darkness. When a Demon Tide attacks Riku, Aqua sacrifices herself by staying on the darkness side of the door to save him. The Demon Tide thrusts her back to the island shore, separating her from Riku and Mickey because the door in the secret place has been sealed and has disappeared from Mickey's side. While fighting the Demon Tide, Aqua vows to guide other lost souls lost in the Realm of Darkness. After its defeat, Aqua rests on the shore, watching the sky. Once Sora saves the worlds, Aqua remains in the Realm of Darkness and not Destiny Islands, as she is not originally from the island, though Master's Defender is returned alongside Destiny Islands.

Blank Period
Later on, after Mickey informs Yen Sid that they have located Ventus's heart, Yen Sid concludes that Terra is the only one left to find, as the two had already located Aqua.

Aqua wanders into the End of Sea, where she meets Ansem the Wise, who was cast into the Realm when his machine exploded. Ansem the Wise reveals to Aqua that the Realm of Light nearly fell to Darkness more than once over the course of the last decade, though it was saved by an exceptionally Keyblade wielder named Sora. Knowing that Sora will rescue her and her friends, Aqua sheds a single tear, while uttering Sora's name with renewed hope.

Kingdom Hearts Dream Drop Distance
Mickey mentions Aqua when he suggests that he help Sora and Riku inside the Sleeping Worlds by following his heart's path, as Aqua told him long ago.

When Sora arrives at The World That Never Was, he is caught by the Organization and placed within a nightmare in which he chases after memories of Riku and Kairi. When he catches up to them at the Contorted City, the phantoms suddenly take the form of Terra and Aqua, while Sora himself takes on Ventus's appearance. Sora is confused, but the phantoms grasp his hand before turning back into Riku and Kairi and walking off again. As Riku attempts to wake Sora on his own side of the dream, Sora recalls when Aqua came to Destiny Islands and nearly wakes up.

However, Ansem appears within Sora's dream at the last second and thrusts him back into the nightmare. Xigbar and Xemnas reappear within the nightmare to taunt him and lead him into despair by explaining the inevitability of their plan and playing on his insecurities, but a defiant Sora proclaims that while he may not have been chosen by the Keyblade, he will always be proud to be there for his friends, including Aqua and all the others.

Kingdom Hearts Guardians of Light
Shortly after meeting Ansem the Wise, Ansem, Seeker of Darkness arrives on the shores of the End of Sea and demands information from Ansem the Wise regarding a girl who had undergone experimentation alongside Xehanort to unlock her forgotten memories. Aqua attempts to defend Ansem the Wise, but she is easily dispatched by Ansem's guardian without her Keyblade. Concerned for Aqua's safety, Ansem the Wise relents and leaves with Ansem, but not before the latter darkens Aqua's heart and casts her out into the sea, leading to her transformation into "Anti-Aqua".

Powers and Abilities
Aqua is a skilled magic user and is a Keyblade user who has proven herself to be a formidable combatant while in battle. The Keyblades she uses all focus on magical strength. Out of the trio, she is the most balanced in terms of strength and speed, making her a capable physical fighter.

She has the most expertise in magic compared to Terra and Ventus, utilizing a barrage of spells as her style, and can use Barrier to completely protect herself. Aqua's magic also gives her access to elemental spells, including special variations of Fire, Ice, and Thunder. Aqua's mastery of magic is almost comparable to Master Xehanort.

Trivia

 * Aqua's name is Latin for "water", connecting to Kairi's name meaning "sea" in Japanese.
