MichonnePlayed by Danai Gurira
Before the apocalypse, Michonne lived with her boyfriend Mike and their three-year-old son Andre in a loft in downtown Atlanta. After the fall, she taught herself to wield a katana and became a fierce warrior. Andre was eventually killed and Mike fatally bitten during a walker attack at their refugee camp. Blaming Mike for Andre's death, Michonne turned him and his friend Terry into walker pets and roamed the countryside alone.
When Andrea falls sick, Michonne cares for her and scavenges medicine in a walker-infested pharmacy. Andrea is on the verge of death, however, when Merle discovers them near a helicopter crash site. He brings them to an idyllic town, Woodbury, where they meet the Governor.
Though Andrea is immediately taken with Woodbury, Michonne harbors a deep mistrust of the Governor, who refuses to hand over her confiscated katana despite her repeated requests. After Michonne leaves Woodbury, she finds the prison and offers to show the group how to gain entry into Woodbury to rescue Glenn and Maggie. Although her secretive nature initially has Rick on his guard, she eventually gains the group's trust and proves to be a valuable asset in defending the prison against Woodbury.
As peace settles in at the prison, Michonne develops a close bond with Carl, procuring comic books and candy bars for him during her frequent supply runs. Her real mission on these runs, however, is to hunt down the Governor. But after months without any tangible leads, Daryl convinces Michonne that the trail has gone cold and she agrees to stop hunting him.
The Governor, it turns out, has not disappeared for good: One day he kidnaps Michonne and Hershel in a gambit to take the prison for himself. Michonne vows to kill him and later delivers on her promise, stabbing him through the heart with her katana during the prison attack.
In the aftermath of the battle, Michonne creates a new set of walker pets and adopts her lone warrior persona once again. She begins having nightmares about Mike and Andre and, no longer wanting to be alone, tracks down Rick and Carl at an abandoned house. Over the following weeks, she grows even closer to Carl, eventually telling him about her son and how Andre's loss turned her into a lost soul. "But Andrea brought me back," Michonne tells Carl. "Your dad brought me back. You did."
