Henry Jekyll

Henry Jekyll, also known as the Groundsman, is an antagonist from the fairy tale drama Once Upon a Time. Though he originally seemed to be the heroic half of Mr. Hyde, his true nature is revealed in the episode "Strange Case," after he attempted to kill Belle in order to exact vengeance against Rumplestiltskin, the same villainous goal as his counterpart.

Jekyll is based on the protagonist from Robert Louis Stevenson's 1886 novel The Strange Case of Dr. Jekyll and Mr. Hyde. He is portrayed by Hank Harris.
