Mary was originally Billy's long lost twin sister whose adoptive family, the Bromfields, took in Billy who had been living on the streets. Their blood connection is not always maintained in adaptations though their foster sibling status is consistent. She originally had her powers derived from a different set of individuals than those that bestowed power on her brother but the first letters of their names still spelt out the magic word SHAZAM: Selena, Hippolyta, Ariadne, Zephyrus, Aurora and Minerva. This was later changed to her powers being derived through the same source as Billy and shared between them and Freddy Freeman/Captain Marvel Jr.
Mary appears in the 2019 film SHAZAM!, portrayed by Grace Fulton and Michelle Borth in her respective normal and superhero forms. Much like in the Geoff Johns run, she is portrayed here as Billy Batson's foster sister, instead of a biological sister.

Mary Marvel/Captain Marvel/Lady Shazam provides examples of:
- Action Girl: One of the oldest ones in comics, actually. Mary is a young superhero.
- Alliterative Name: As Mary Marvel.
- All Your Powers Combined: In the Golden Age & Pre-Crisis stories, and in Jeff Smith's variant, Mary draws on Selena's Grace, Hippolyta's Strength, Artemis' Skill, Zephyrus' Speed (and flight), Aphrodite's Beauty, and Minerva's Wisdom. In the regular Post-Crisis continuity she gains her powers from the same mythological beings as Billy (which better justifies their having the identical powerset). She briefly gained them from the same sources as Black Adam as well.
- Badass Adorable: Much of the time, but particularly in Jeff Smith's version.
- Badass Cape: Usually Mary wears a white cape trimmed in gold, which often has an attached hood.
- Beware the Nice Ones: In Superbuddies, she's portrayed as incredibly sweet and naive... and then gets Mind Controlled and proceeds to almost kill Captain Freaking Atom.
- Brainwashed and Crazy: In Countdown to Final Crisis.
- Chest Insignia: Same as the rest of the Shazam powered supers Mary Marvel's got a lightning bolt across her chest.
- Clark Kenting: Averted in the 90s series, where she turns into an adult under the influence of the magic. Played straight Pre-Crisis and in Monster Society of Evil.
- Comic-Book Fantasy Casting: Just as Captain Marvel was visually modeled after Fred MacMurray, Mary Marvel was modeled after Judy Garland.
- Cute Bruiser: In both the regularly continuity and even moreso in Jeff Smith's version.
- Dangerously Short Skirt: Look any further under it◊, and she'll shock you.
- Demonic Possession: By Desaad in Final Crisis.
- Distaff Counterpart: Possibly the first superhero example, and the trope codifier for the genre.
- Drunk on the Dark Side: In Countdown she briefly starts sharing Black Adam's powers and goes flying off the deep end.
- Expy: In an odd series of developments, an editor ordered his writers to base Captain Marvel on Superman (although he turned out quite different and more lighthearted); Wonder Woman was apparently based on Captain Marvel (with the similar grounding in magic, and more specifically the divine gifts); Mary Marvel seemed based on Wonder Woman; Supergirl was based on Mary Marvel; and Power Girl was based on Supergirl.
- Evil Costume Switch: Provides the trope image. When Mary acquires Black Adam's powers, her costume turns black and she gains a new level in moral ambiguity. It's taken even further in Final Crisis where she sports a dominatrix outfit and pink pigtails on an otherwise shaved head.
- FaceHeel Turn: In Countdown to Final Crisis. In Final Crisis, it was Retconned as Demonic Possession.
- Flying Brick: Her usual powers, but mystical in nature.
- Friend to All Children: Loves children, fitting considering shes a child in her normal form.
- Fun Personified: A trait she retained Post-crisis, even when the DC Universe was getting darker and darker around her.
- Genius Bruiser: As with Billy this is dependent upon her using the Wisdom of Solomon (Minerva in the Pre-Crisis continuity). In the 90s series, she was more prone to doing this than he was.
- Henshin Hero: One of the earliest, she is a normal human when she's not transformed into the superpowerful form of Mary Marvel.
- I Just Want to Be Special: Mary cannot stand not having her powers to the point of addiction, even to the point of stating her powers were the only trait that gave her life purpose and disparaging being normal. When she lost her powers after the death of the Wizard Shazam, she went to desperate lengths to get her powers back, even trusting and taking the powers of Black Adam with his permission which led her down the path of corruption and evil.
- Incorruptible Pure Pureness: One of her defining character traits, including the wonderful handling in the 12-part "I Can't Believe It's Not The Justice League" story. The weakly Hand Waved subversion of this is one of the many issues fans take with Countdown to Final Crisis and Final Crisis.
- Kid Hero: Most incarnations shes a kid with the ability to transform into a adult.
- Long-Lost Relative: Originally and in several subsequent adaptations she's Billy's long lost twin sister.
- Magic Skirt: Her usual attire is a short dress that should be a constant wardrobe malfunction considering she's a flyer.
- Minidress of Power: All her super costumes are dresses.
- Most Common Superpower: Upon transforming from Mary Bromfield to Mary Marvel, her breasts grow to d-cup sizes.
- Motor Mouth: Was this in one issue from the early 2000's when Fire bought an apartment with her. Had to do with Mary discovering coffee for the first time.
- Nice Girl: Extremely friendly and likable in both forms. Her extreme compassion rivals her brother.
- Nigh-Invulnerability: At times considered impossible to harm in her transformed form.
- No Celebrities Were Harmed: Her appearance was originally based on Judy Garland.
- Older Alter Ego: Sometimes (in the '90s series), sometimes not (originally, currently, and in Jeff Smith's version).
- Plot-Relevant Age-Up: For Mary's superhero form towards the end of Billy Batson and the Magic of Shazam (which follows the Jeff Smith continuity). Mary says the magic word at the Rock of Eternity (where the magic is more unstable), and when the smoke clears, her superhero form is no longer a child.
- Put on a Bus: Almost.
- Sexier Alter Ego: Mary Marvel is taller, leggier, and older than Mary Bromfield in the 90s series.
- She's Got Legs: As Mary Marvel
- Sibling Team: With Billy
- Spoiled Sweet: Golden Age Mary was raised in luxury by her adoptive mother, a noted society lady by the name of Bromfield, and led a much more sheltered life than either Billy or Freddy. It didn't stop her from being the kindest-hearted girl in the Marvel Family.
- Statuesque Stunner: As Mary Marvel in the 90s series, where she grew to about six feet tall.
- Super Intelligence: By accessing Solomon (or Minerva)'s Wisdom, Mary can reason out solutions to problems that are far beyond her.
- Super Reflexes: A given when empowered by six gods known for their sharpness in battle.
- This Is Your Brain on Evil: Again, Countdown. It was so egregious that Shazam decided Mary wasn't worthy of her powers and removed them immediately after his resurrection.
- Thou Shalt Not Kill: Her usual mo. Not so much when shes evil.
- Unrelated in the Adaptation: While the original Mary was Billy's blood related sister, given the strangeness of her introduction, there have been several adaptations simplify their relationship by making her an adoptive sibling, emphasizing his difficulty socializing with a new family in contrast to his brief stint at being homeless/living as an orphan.
- UST: On and off with Captain Marvel Jr. who she's married in some realities where they're both allowed to become actual adults.
