Ventus

Ventus (also known as Ven) is a main protagonist in Kingdom Hearts Birth by Sleep. From the view of the story, it is revealed that he is one of the Keyblade Wielders before Sora and has a strong bond to him. Ventus, along with Terra and Aqua, fights against Master Xehanort and Vanitas. He is the youngest of the three Keyblade Warriors when it comes to age.

While his name Ventus means "Wind" in Latin, Sora's name in Japanese means "Sky". The connection between the two is explained at the end of his story mode.

Kingdom Hearts Birth by Sleep
Ventus is the youngest of Master Eraqus's three apprentices. The game opens up with a clip from his past, revealing a connection to Master Xehanort. In this flashback, Ventus has an Awakening and finds that his Station of Awakening is broken off. He hears Sora's voice, and he offers to connects with his heart until one day he complete his own heart. Sora's heart fixes his Station.

Xehanort took Ven to Master Eraqus to learn from him how to become a Keyblade Master. Terra and Aqua met Ven with open arms. However, when Terra asked Ventus about who he was, where he was from, among other things he panicked, eventually falling unconscious. Eraqus revealed that this was because Ven had lost his memories. Afterwards he remained asleep for some time, although he did awaken eventually.

It was then that his heart began to heal and he started to form strong bonds of friendship with Terra and Aqua. One flashback scene even shows Terra and Aqua trying to reassure Ven after he lost a training match. Terra even went so far as to give Ven his wooden training Keyblade, which he carried with him throughout the game until he reaches Neverland.

Years later, following the Master Qualification Exam, he once again earns the interest of Master Xehanort and his apprentice Vanitas. After dark hints regarding Terra left by Vanitas, Ven attempts to follow Terra and embarks on a journey of his own in order to save his friend.

Along the way, it is revealed that Ventus was once the apprentice of Master Xehanort and that Vanitas was actually a being created from the darkness of Ventus's heart. At one point of their training in the Keyblade Graveyard, Xehanort summoned multiple Neoshadow and persuaded Ventus to use his darkness. However, he refused to comply and was defeated. Deeming him to be too weak, Xehanort created Vanitas and Ventus gained amnesia in the process. In order to make him stronger for the creation of the X-Blade, Xehanort delivered Ventus to Eraqus.

After learning of his past, Ventus returns to Eraqus in order to discover more. Realized Xehanort's plan, Eraqus proceeds to destroy him. Fortunately, he is saved by Terra and sent to Destiny Islands, much to his displeasure. There, Vanitas is waiting for him, causing him to fully remember his past with great pain. Before leaving, Vanitas tells Ventus to go to the Keyblade Graveyard, where he will see Terra and Aqua one last time. Once reunited with his friends, Ventus requests to be erased, much to their shock. Before they could reply, Xehanort and Vanitas appear and the battle begins.

During their final battle at the Keyblade Graveyard, Ventus is frozen in the process. Aqua manages to catch him, saving his life. Braig quickly appears and fights Aqua. Stalling long enough, Braig withdraws from the battle. Vanitas knocks out Aqua as he drops down from a cliff. Before the enigma could finish her off, Ventus uses all of his willpower to thaw out of his frozen state and fights Vanitas. To this end, Vanitas summons many Unversed to hold Ventus down as he forcefully integrates into him completing his heart. Vanitas and Ventus are transported to the Awakening, engaging in a metaphysical battle while Aqua and Mickey Mouse battle Ventus, possessed by Vanitas.

Vanitas is defeated in the two fights and fades out of existence. However, this also results in Ventus losing his heart. Aqua later places his body in the newly created Chambers of Repose and Waking (and, by extension, Castle Oblivion). Somehow, Ventus's heart finds its way to a young Sora, in his own Awakening, and his heart passes on into Sora's body.

Kingdom Hearts 358/2 Days
While Ventus does not make a physical appearance in the game, Xemnas and Xigbar see Xion (a Replica of Sora) as Ventus. Xigbar reveals that his complete being has met the real Ventus.

Kingdom Hearts II
In The World That Never Was, Sora encounters Xigbar, who mentions "the others", referring to Terra, Aqua, and Ventus.

Abilities
Ventus is the fastest of the trio, using swift combo attacks with quick movements. Unlike most Keyblade wielders, Ventus wields his Keyblade, Fresh Breeze, in a reverse grip. Aside from his impressive speed, Ventus also utilizes a variety of magic, including new and unique spells such as the Zero Gravity. He also seems to have access to some of Sora's very own techniques, such as the Strike Raid. His known Command Styles are:

Level 1 Command Styles

 * Speed Rave: Ven's personal Command Style that puts a large emphasis on overwhelming enemies with wide-ranged, speed-based combos. Activated by filling the Command Gauge with physical-based commands.
 * Thunder Bolt: A swift Command Style that unleashes powerful lightning upon attacks. Activated by filling the Command Gauge with Thunder-based commands.
 * Fire Blazer: A ranged and versatile Command Style that focuses the Keyblade to erupt in flames while attacking. Activated by filling the Command Gauge with Fire-based commands.
 * Diamond Dust: An ice-based Command Style that seems to specialize in crowd-control and dealing with multiple enemies. Activated by filling the Command Gauge with Ice-based commands.
 * Ice Blast: Another ice-based Command Style that uses an ice cream theme. Randomly activated by filling the Command Gauge with an Ice Cream item.

Level 2 Command Styles

 * Cyclone: After meeting certain requirements, Ven's initial Command Style morphs into the much more powerful Cyclone Command Style, attacking surrounding enemies with spin attacks. Activated by filling the Style Gauge with Raid, or Aero-based commands.
 * Wing Blade: An omni-directional Command Style designed to combat multiple enemies from all directions with a wingspan of phantom swords. Bears a resemblance to Riku and Sora's "Session" limit. Activated by filling the Style Gauge with physical, counter, or Magnet-based commands.
 * Air Rider: A Command Style that gives Ven great midair advantage, it allows him to ride his Keyblade around to attack foes from above at high speed. Activated by filling the Style Gauge with evasive, or Zero Gravity-based commands.

Additional abilities include:
 * Dimension Link: An ability that allows Ventus to summon character's powers from other worlds to aid him in battles.
 * Shoot Lock:
 * Photon Charge: Rush to locked on enemies for multiple hits. If the lock on number reaches MAX, a pillar of light raises for a Finish attack (The information for how to input it isn’t written, but according to last year’s trailer, you have to hit once at the correct time.). “Lock on to all enemies in the area.” “A straight attack with the speed of light!”
 * Pulse Bomb: Ventus holds his Keyblade backhanded and sends out energy from the light of the Keyblade, causing many small explosions.
 * Multi Vortex: Ven starts by slashing in all directions multiple times before spinning and creating a giant tornado filled with shooting stars.

Personality
As mentioned earlier, Ventus is the youngest of the three Keyblade warriors. Personality-wise, he has many similarities with Sora; he's sweet, cheerful, curious, and gets excited at anything new or interesting. He also makes new friends easily in different worlds and really cares about his best friends Terra and Aqua, viewing Terra as an older brother. Ventus is very much unable to cope with Terra turning and subsiding to the darkness in his heart. Some of his traits might have passed on to Sora when his heart joined him.

Appearance
Ventus bears an uncanny resemblance to Roxas, bearing identical facial features. Further highlighting this resemblance is Ventus's outfit, which is strikingly similar to Roxas's own Twilight Town clothes. He wears a jacket that resembles a fusion of Roxas's jacket (white on the right side) and Sora's jacket in Kingdom Hearts II (black on the left side). The collar of the jacket is red and pleated, again, similar to the collar on Roxas's own jacket. Underneath this, he wears what appears to be a grey vest with a single button and several white, angular patterns on it. He wears a third layer under this, in the form of a plain, high-necked, black shirt. He also has a chunk of dull green and grey armor on his midsection that appears to be under his vest, and another piece of armor on his left shoulder. Master Eraqus wears a similar piece of armor, though more blue-green, and more obvious.

Ventus's pants are also similar to the pants Roxas wore, though Ven's balloon outward slightly before closing up about halfway down his legs, similar to caprice pants. These pants are colored in shades of grey, black, and white. He also wears an ornate, dull green and grey piece of armor on his upper-left arm, along with a black and white checkered wristband that is, once again, strikingly similar to Roxas's, but with white edges as opposed to Roxas's black-edged wristband. Like Aqua, he wears two criss-crossing straps on his chest, on which he wears a silver badge vaguely resembling the Heartless emblem or the Nobody emblem turned upside down. His boots are rather odd when compared to Aqua's and Terra's, as they resemble an armored version of normal street shoes in shades of dull green and grey.

When touching the piece of armor on his shoulder, Ventus becomes full clad in armor. In "Birth by sleep", Ventus's suit of armor shares the coloration of the pieces he normally wears, predominantly sporting shades of green and gold. In this suit, Ventus adds a yellow cape to his outfit that is discolored, almost appearing rusted. The armor on his knee is gold and bears a sharp, upward-pointing hook on the outer side of each one. Ven's helmet has a notably different design from Aqua and Terra's, appearing more squashed and flat at the top. His helmet also has two prongs on either side of his head which point backwards and angle diagonally upward. Strangely, Ven's boots are colored completely gold in this outfit, as opposed to the multi-colored ones he normally wears. In Kingdom Hearts Birth By Sleep, Ventus's armor is altered. He loses his cape, his boots change to more closely resemble those in his unarmored state, and the coloration changes much more than Terra or Aqua's. Ven's armor loses the greens entirely, now sporting steel blue, gold, and black armor, with several red lines decorating it.

At the end of Kingdom Hearts Birth by Sleep, Ventus fused with Vanitas and ended up taking on the appearance of Vanitas's red and black bodysuit. While Ventus's head remained the same, his eyes were changed to the color of Vanitas's eyes.

Trivia

 * The Japanese Birth by Sleep website's startup screen refers to Ventus as the "Swift Wind Returning to Bonds" (絆巡る疾風).
 * In the end of Ventus's story in Kingdom Hearts Birth by Sleep, Ventus's heart finds its way to a young Sora while Sora was in his own Awakening and merges his heart into Sora's body, thus explaining why Roxas (Sora's Nobody) resembles Ventus and why Xion (an imperfect Replica of Sora) is seen as Ventus by Xemnas and Xigbar.
 * The badge on Ventus's chest slightly resembles the symbol of the Nobodies turned upside down. The same badge is on Aqua's chest, Master Eraqus's belt and Terra's belt (except Terra's is yellow).
 * In the opening of Kingdom Hearts Birth by Sleep, Ventus is shown falling the same way Sora does at the Kingdom Hearts opening movie and the same way Roxas does at the end of the Kingdom Hearts II opening movie, but with Ventus, the Kingdom Key and Soul Eater are floating as he falls.
 * In his final battle against Vanitas in his Awakening, Ventus says the equivalent to Sora's "My friends are my power" line word-for-word, adding more to the Ventus/Sora connection.
 * Ventus is shown to stand in the same stance that Sora often does, with his hands behind his head. Several of Ventus's attacks also resemble both Roxas's attacks during his boss battle in Kingdom Hearts II Final Mix and Sora and Riku's Limit Eternal Session in Kingdom Hearts II.
 * Ventus is one of only five characters in the series to call King Mickey by his name only. Others include Yen Sid, Aqua, Riku, and Data Sora.
