Mr. Gristle is the secondary antagonist of Laika's 3rd full-length animated feature film The Boxtrolls. He was voiced by Tracy Morgan. The shortest of Archibald Snatcher's henchmen, Mr. Gristle is perhaps the most sociopathic of the Red Hats, second only to Snatcher himself. Unlike Mr. Trout and Mr. Pickles, Gristle has no moral qualms or doubts about his job as a Boxtroll hunter, nor about hurting anyone along the way. He follows orders with sadistic joy, taking delight in other people's misery and discomfort, even his own colleague's- when Snatcher's face began to swell due to his cheese allergy, for example, he could only giggle with glee as Pickles and Trout looked on in horror and disgust. Though he did help heal Snatcher's cheese fix by throwing leeches on his face, it was less about helping his fellow Red Hat and more about it being "funny" to him. Gristle is also the least talkative of the Red Hats, often parroting single words that other people say with an enthusiastic shout, such as "Hat!" or "Throat!".
