Michonne is introduced as a mysterious woman armed with a katana. She first appears towing two armless, jawless zombies in shackles and causes no small consternation among the group. She saves Otis from zombies and follows him to the abandoned prison where the group is based.[6] She immediately bonds with Tyreese, recognizing him from his days in the NFL, and shares his passion for weightlifting.[7] They sleep together, precipitating Tyreese's breakup with Carol Peletier; Michonne and Tyreese then become a couple.[8]
