William Joseph Batson, nicknamed Billy or Shazam, is an teenage boy who was chosen by the wizard Shazam to be his champion, granting him enormous magical powers. Billy appears to be a cynical troubled boy who has no respect for authority and prefers to be alone, but his behavior is a result of being separated from his mother as a toodler. He can be reserved and quiet. Despite his flaws, he is an inherently good person. In his champion form, Billy is more upbeat and willing to have fun.
