The 33-year-old assassin of the Malkin witch clan, she is a malevolent witch skilled with knives and scissors in combat. Her mark is a pair of scissors. She nonetheless follows a strict code of honour not to use trickery in combat, to the point where, when ordered to kill Tom, she regretted it as she would not be able to face him when he was at his prime, and offered him a quick death (although he did survive). She gained protection from the Fiend by bearing him a son. The baby was not a witch but an ordinary boy so the Fiend killed him, resulting in her swearing to destroy him. For that reason she’s unlike the average antagonist as her hatred often makes her side with Tom. Grimalkin is the best character in physical limits and has battle smarts. She is the best Malkin Clan assassin. Credit to wiki.
