Adam Crown (Earth-616)

Adam Crown was a seemingly ordinary young man chosen by the Green Knight to carry the Pendragon spirit of King Arthur, and to lead the Knights of Pendragon in their final battle with the forces of the Bane. He remained with the newly reformed Pendragons for some time afterward, but eventually elected to leave them when most of the team split up. He later sacrificed his own life to prevent Bodb Derg from entering Earth by shoving the creature back through the portal he came from.
