Maps Mizoguchi src

Mia 'Maps' Mizoguchi is an excitable and curious first-year student of Gotham Academy and one of Olive Silverlock's best friends, as well as the little sister of her boyfriend Kyle. She is known for her love of fantasy, exploration, and cartography -- the latter being source of her nickname -- as well as her boundless enthusiasm.

The Ghost of Gotham Academy

Maps became a first-year student at Gotham Academy the year her elder brother Kyle was in his final year, and was assigned Olive as a guide to get used to the campus. The two began investigating reports from students about a ghost appearing on campus, with Maps being ecstatic about exploring the school and going on an adventure. The two eventually join forces with Pomeline Fritch, a haughty classmate of Olive's who had attempted to raise Mille Jane Cobblepot's spirit and believes the ghost sightings to be her; Maps also recruited Colton Rivera, a delinquent upperclassmen, for his lock-picking skills.

Together, the group snuck around the school to investigate, eventually discovering that the "ghost" was a hoax, and that the ghostly eyes that they had seen within the school were Killer Croc's, a friend of Olive's mother who had escaped Arkham Asylum.[1][2] The group tracked Croc through the school's secret, centuries-old underground tunnels, which connected the asylum to the academy; however, Batman was on the same trail, forcing Croc and the group to flee. In the aftermath, Maps decided to form a secret Detective Club with the group and her older brother in order to formally investigate the connection between the asylum and the school.

Meeting Damian Wayne

Mia and Damian.

Not long afterwards, one of the group's leads was covertly stolen by Robin, who also enrolled in the Academy as a civilian.[3] When fantasizing about the perfect team for the new club, Maps was drawn to Damian's fighting skill. After writing his name next to hers with a strange quill she had previously taken from the Headmaster's office during the club's outings, the two of them suddenly became magically bound to each other by the hands. After a raven stole the feather, the two went on an adventure to take it back, befriending each other along the way.

Eventually, the quill is confiscated by Professor Scarlet and their hands are able to separate; though the faculty attempted to convince the two of them that it was all in their imagination, they later found that someone had scribbled out what Maps had written. Damian was expelled by the headmaster after taking the fall for the quill's theft, and gifted Maps a Batarang before leaving.[4]

We Are Robin!

Maps later attended the funeral for Olive's mother, who had passed away while incarcerated. While investigating the possibility that her death was faked, Maps came face-to-face with Red Robin, who believed her to be part of the "We Are Robin" movement.[5] Through him, Maps learned that Olive's mother was latest in a long line of blood-related, white-haired supervillains called "Calamity", who once terrorized Gotham with her pyrokinetic abilities until she was apprehended by Batman and the first Robin. Dr. Hugo Strange, had hoped to coax Calamity out of Olive for his own gain, but was thwarted by the Detective Club.[6]

As the "We Are Robin" movement continued, it was outlawed by Gotham City and academy students found participating were expelled. When prominent movement member Riko Sheridan was transferred to the academy, she earned the admiration of Maps; however, in order to protect Maps from being put in danger by association, Olive reported Sheridan to the authorities. Maps is stopped from intercepting the police by Robin (whom she does not realise is Damian Wayne) who assured her that due to the activities going on within the city, Riko's temporary arrest would actually protect her. He had hidden gear around the campus for Maps' perusal, promised her that he would keep in touch when her help is needed and asked that she avoid adventures until then.[7]

Second Semester

Maps cornered by her mind-controlled peers.

When Mia returned to the academy after Christmas break, she was disappointed to find that a new student named Amy had become Olive's roommate instead of her, and that Olive continuously blew off the group. She managed to advance into second-year English, the same class as the rest of the Detective Club; the group's first mission of the new semester was to investigate the sudden disappearance of Elith Pio, the professor who was supposed to lead the class. They discovered that Pio had been kidnapping and mind-controlling students into mass-burning the school's books in order to get revenge on Professor Scarlet, a fellow academy professor who had manipulated her into looking for the Book of Old Gotham.[8][9]

While breaking into administrative offices in search of a way to deactivate the Mad Hatter tech that controlled the students, Colton was caught and expelled by the Headmaster.


  • Cartography: Maps' favorite hobby is the drawing and studying of maps and she tries to always have her tools along.
  • Investigation
  • Lock Picking: Colton has been teaching Maps how to pick locks, though she's as of yet a novice.
  • Throwing: Maps has been given a couple of Batarangs by Robin which she has gotten adept at using.

  • Maps is a huge fan of Batman and fantasizes about becoming Robin, frequently drawing the two of them on adventures. She once snuck into the GCPD precinct building to activate the bat-signal and prove herself to him, but fell asleep before he arrived. He returned her to her dorm and signed her drawings.[10]
  • Maps is an avid fan of "Serpents & Spells", a Dungeons & Dragons analogue, and was once gifted a first edition copy of its handbook by Damian Wayne.[11]
  • Despite her intelligence, Maps' grades in school are apparently quite poor.[8]
