Dr. Terminus

Dr. Terminus was the main antagonist of the Disney 1977 film Pete's Dragon.

Pete's Dragon
Dr. Terminus was a con artist who specialised in selling "miracle cures" to unwary individuals but became obsessed with capturing the dragon Elliot as he reads up on the legends of how dragon body-parts are said to be infused with many useful properties.

Dr. Terminus plans on capturing the dragon so as to dismember him and use his body-parts to create new "miracle cures" to make himself rich - in order to do so he allies with the gruesome Gogans, who wish to get rid of Ellliot so that they can force Pete into a miserable life of child-labor and cruelty.

In the end Dr. Terminus meets his defeat when, in an effort to harpoon Elliot, his leg is caught in the rope and he is sent catapulting through the ceiling.
