Grindette is Grinder's robotic bride who first appeared in the episode Bride of Grinder
Grindette first debuted in Bride of Grinder after Grinder was sad with being all alone with no one to love him. She was made so he wouldn't be all alone and when normal electricity failed to bring her to life, Dr. Buttocks decided to take her and turn her into a spy under his control so he could find the Tree of Life. Ultimately, her love for Grinder prevented her from becoming truly evil despite Dr. Buttocks' attempts.
She was shown to have laser equipment, an umbrella inside of her head and incredible throwing strength as she managed to destroy Dr. Buttocks' computer after throwing the wedding ring.
