Banzo (H&H)

Banzo - also known as Stitchbuddy - is the family dog of the Greywhinders, who was killed by Martin and turned into a stuffed toy, capable of changing size and becoming a monstrous creature As seen by his preference to prioritize Ava, Banzo isn't entirely heartless nor cruel. At least not to those who he had loved previously. He seems to have his own personal interest to protect her by any means necessary, even if it is at his own expense. When Martin demands for him to murder Ava, he's shown to be more hesitant as the audience is given a choice between acting on his demand or refusing to stay obedient. Because of the emotional connection these two shared in both life and death, some fans speculate that Martin had killed Ava upon Banzo's refusal to do so himself.
