Ventus (voiced by Jesse McCartney) is a character from Kingdom Hearts: Birth By Sleep.
He was a Keyblade appentice who teamed up with his friends Terra and Aqua. They dreamed of becoming Keyblade masters.
Ventus' heart is severely damaged by the creation of his dark counterpart, Vanitas, then again when the X-Blade forged by their hearts is destroyed. Both times, Sora's heart reaches out to mend his heart. By the end of Kingdom Hearts: Birth By Sleep, Ventus' heart has gone to sleep within Sora so that it can recover until it is fully healed and ready to rejoin his body, which lies comatose but safe within the Chamber of Waking.
