Ventus was chosen by the Master of Masters to become a Dandelion and one of the five members to be a replacement Union leader.
His name means "wind" in Latin, similar to how Sora's name is Japanese for "sky". The official Japanese website refers to Ventus as the "Swift Wind Returning to Bonds" .

He is younger than the other union leaders.

Note that Ventus is voiced by Jesse McCartney in the original series.  https://www.youtube.com/watch?v=SqsKjXAX-yg For reference. It would be great if you have the same tone, but give your own version of him a go, too!
