Ventus

Ventus (also known as Ven) is one of the three main playable protagonists of Kingdom Hearts Birth by Sleep and a Keyblade Wielder. Ventus is the youngest of Eraqus' three pupils; he is very kind, sweet and possesses a strong thirst to prove himself. Ventus was originally present during the events of Kingdom Hearts χ[chi], being one of the five Dandelions chosen by Ava to be new Union Leaders. Many years later, Ventus became an apprentice to Master Xehanort, who wanted to use the young boy to forge the legendary X-blade. However, Ventus proved to be a poor choice when he refused to use the darkness within his heart against the heartless. Frustrated, Xehanort used his keyblade to extract Ventus' darkness which quickly morphed into the physical form of a human. Master Xehanort named this new being "Vanitas". Ventus' heart was severely damaged after this experience and so it sought out another heart to connect with, eventually coming into contact with Sora. Ventus' heart took refuge in Sora's heart with the young boy's permission in order to mend itself. Due to his connection to Sora, the latter's nobody shares an identical appearance with Ventus. While Ventus' official introduction occurred in Kingdom Hearts Birth by Sleep, he was first seen in the secret ending of Kingdom Hearts II, though we did not see his face until the extended secret ending of Kingdom Hearts II Final Mix.
