This is for the Western Civilization Board Monthly Art Theme May: Mary Marvel - A personal favorite of mine as Mary Batson is particularly powerless with a gag over her mouth. So let's make this one all about the World's Mightiest Girl!

It seems that Mr. Mind, the evil alien worm, has captured Mary Marvel. Now he is gloating about his victory. This is going to take awhile.

Mary Marvel (Mary Batson AKA Bromfield) is the twin sister of Captain Marvel and a member of the Marvel Family, given incredible powers by the wizard Shazam. Originally Mary Batson is adopted under the name Mary Bromfield, although she later discovers Billy Batson is her long-lost brother. She has been a member of the Justice League and Super Buddies. Mary Marvel was created by Otto Binder and Marc Swayze, first appearing in Captain Marvel Adventures #18. (1942)

Mary’s story is inherently linked with that of her namesake, Captain Marvel, known as Billy Batson in his alter ego. Before attaining any superpowers, she met Billy and Freddy Freeman at a game show hosted by Batson. Through a series of revelations, it becomes clear that Mary and Billy are siblings. Mary, soon after, is kidnapped and upon being rescued by Captain Marvel and Captain Marvel Jr. (the alter ego of Freddy) the family connection is revealed to her as well. Through necessity, after Billy and Freddy are captured, she discovers that the magic phrase operates with her as well. She then meets the wizard Shazam who reveals her powers are not the same as Billy’s, though they are similar. She takes on the name Mary Marvel and fights crime alongside her new friends.

Following the reboot of the DC Universe after the events of Crisis on Infinite Earths, the origin story of the surviving Marvel family members is slightly retold. Mary and Billy Batson's parents are now archaeologists and Egyptologists. At the age of nine, Mary goes with her parents on a Sivana-sponsored expedition and Billy stays at home. An associate of the Batsons is a man named Theo Adam, who happens to be the half-brother of Sarah Primm. Adam kills the Batson parents when they unearth a priceless jeweled scarab, and steals Mary back to . Mary looses her memory, both of her life as a Batson, and of the murder of her parents. Adam places Mary into the care of Primm, who at the time is working as a maid for Nick and Nora Bromfield. As with his previous history, Billy is eventually chosen by the wizard Shazam to be his champion, and is given the power of Captain Marvel. One of the first tasks the old wizard gives to Billy, is to find his lost sister. After some searching they discover Mary at a spelling bee hosted by WHIZ radio and is being emceed by local teenage host Billy Batson. Also entered in the bee is a young boy named Freddy Freeman. Mary wins the spelling bee, and is whisked away only to be kidnapped. Billy rescues the girl, but she is soon kidnapped again, proving there is a conspiracy to collect a ransom from her adoptive parents. Billy begins to think about how familiar Mary seems. He soon discovers that Mary is his lost sister. Mary soon discovers that the powers of Shazam apply to her as well and, as with the golden age story, she must go free her brother from kidnappers. In the new universe, Mary's powers no longer stem from a different set of gods than Billy's, but instead share from a finite store of the magic which the wizard Shazam serves as a conduit.

Her story is to be rebooted once again in the DC Universe after the new 52. In this universe, she meets Billy as the two are placed together in a foster home. As the child that has been there the longest, she is given some level of authority over him in the house. The story is ongoing.
