Roxas

Roxas is Ventus' nobody. He first was formed after Ventus gave up his Heart in Kingdom Hearts Birth By Sleep. Roxas is very shy when he was first born. He eventually became friends with another Organization Member named Axel and then another member that was created in the future Xion. Things eventually go wrong for Roxas as Xion dies and returns to Sora's Heart. Then he left the organization and faced off Riku. Riku destroyed him and Roxas regained his heart. This eventually led to Kingdom Hearts II when Roxas re-meets with Axel and they face off. Then eventually in the end of the game he finally meets Sora and Roxas dies in the end, but enters Sora's Heart like Xion did
