Michonne is a fictional character from the comic book series The Walking Dead and is portrayed by Danai Gurira in the television series of the same name. Armed with a katana and harboring a mysterious past, Michonne is introduced clothed under a hood and pulling the shackles of two reanimated corpses for protection and camouflage. The two walkers are subsequently revealed to be her zombified boyfriend and his best friend. In both the comic and TV series, she has a prominent role in the conflict between the town of Woodbury led by The Governor, and the Prison crew (of which she was a member).
The direction of the character is contrasted between the two mediums (though in both mediums, Michonne is introduced as an outsider who quickly proves to be a valuable asset). In the comic, Michonne is a former lawyer as well as a divorcee with two missing daughters. She forms a complicated relationship with Tyreese. Her conflict with The Governor is much more violent in the comics, enduring sexual assault before mutilating him in revenge. Michonne's mental state deteriorates after many losses, bringing her closer to Rick Grimes who shares similar trauma. Despite finding temporary peace with Ezekiel at The Kingdom, Michonne runs away to Oceanside before making a return. Her absence was explored in a 3-episode Telltale Games mini-series, exploring her departure and living life at sea.
Michonne's backstory is slightly altered in the television series, having a three-year-old son named Andre Anthony, while the fate of her boyfriend and friend remain the same. In the television series, Michonne's trauma and guarded nature gradually diminishes as she slowly recovers and finds herself opening up and investing in a community as well as Rick's core group. Her conflict with The Governor is motivated by his attempt to kill her after leaving the town under suspicion that he is dangerous and trying to protect her friend, Andrea. In addition, her relationship with the Grimes family is explored in more depth as she pushes her group to strive for a sanctuary in Washington, DC. In both mediums, she becomes a constable at the Alexandria Safe-Zone.
The character has been critically praised, often regarded as a fan-favorite in both mediums. Michonne was voted #86 on IGN's Top 100 Comic Book Heroes and Gurira's performance has been well received.
