“Take good care of Dani, Max. You'll never know how precious she is, until you lose her...”
―Binx advice to Max
Thackery Binx is one of the tritagonists in Hocus Pocus. He is turned into an immortal black cat in the beginning of the film. During the film, he finds himself growing attached to Dani Dennison.
Thackery was a 17th-century boy living with his mother, father, and sister, Emily. One day, he followed her into the woods, but was unable to rescue her from the three Witches, and after insulting Winifred, was transformed into an immortal black cat. After the sisters were hanged, he was unrecognized by his family and was abandoned. At some point afterwards, he decided to guard the house every Halloween night in order to prevent the sisters from returning. In 1993, when a teenage boy named Max Dennison accidentally brought them back, he acted as a guide for him, his sister Dani, and his crush, Allison. During the adventure, he quickly takes a liking to Dani, and bonds with her. When the Sanderson Sisters disappear off the face of the earth at sunrise, his soul is freed. He leaves with Emily when saying goodbye to Max, Dani, and Allison.
Thackery is shown to be a caring, brave, and determined character, as he cares about his family, and also, after he loses Emily, he becomes determined not to fail anymore, no matter what it takes. He has also been shown to be a loving brother to her, as he was determined to save her from the sisters, even though he failed. He is also cautious, as demonstrated when expressing that the spellbook must be kept shut. During his time with the children, he becomes attached to Dani and cares about her.
