Mecha-Grunty

Mecha-Grunty is from the game Banjo-Kazooie: Grunty's Revenge, which is a story set 1 year after Banjo-Kazooie and 1 year before Banjo-Tooie. She has taken Kazooie captive and it's up to Banjo to get her back. Mecha-Grunty is a robotic version of Gruntilda which is housing her soul while her body is trapped in her grave after the events of Banjo-Kazooie. She is defeated at the end of the game and her soul returns to her body, while she waits for her sisters to remove the boulder trapping her.

Note: It is possible that the Mecha-Grunty is a previous model of the Hag 1, seeing as her hat is a drill and on her waist there's a plaque that reads HAG 1
