When Ventus was attacked by the Heartless in the flashback, Xehanort took the darkness in Ventus' heart and it took the shape of Vanitas, but that left Ventus incomplete. After a while, Xehanort took Ventus to Destiny Islands so he could rest in peace at the same time Sora was being born. Their hearts connected, and since from then on Sora is replacing the darkness in Ventus, Vanitas resembles him.
