Poole is based on the character of the same name from Strange Case of Dr Jekyll and Mr Hyde.
In the Land of Untold Stories, Poole is an orderly that works for the warden, Hyde, who is the darker side of a doctor, Jekyll, with both of them sharing the same body as a result of a mishap. Hyde's control over the body while Jekyll is "awake" is not fully understood, but it is known that if Jekyll drinks a blue serum, he will become dormant in the body while Hyde takes his place. To keep Jekyll from escaping, Poole is left in charge by Hyde to keep watch on his other half. Without either Hyde or Poole knowing, Jekyll begins growing a purple flower that will serve as the final ingredient in a serum meant to permanently separate himself and Hyde into two different bodies. When a group of strangers approach Jekyll for help returning home, Poole tasers them into unconsciousness before imprisoning them. Later, he catches Jekyll in the hospital lab after fixing the group's broken wand that they need for going home. Jekyll tries to lie his way out of the situation, and when he tries to escape, Poole ends up cutting him on the cheek. He forces him to ingest the serum to wake up Hyde, despite the latter's protest that Hyde doesn't like being disturbed. Hyde becomes interested in the wand's power and believes it's time that he travels to another realm instead of being stuck in this one. With Poole looking on, Hyde uses the wand to reach into the Land Without Magic, where he steals Pandora's Box, which contains the Dark One's pregnant wife. ("Only You")
Poole guards Jekyll, who is left in a straitjacket after Hyde becomes dormant, but he ends up falling asleep. When Jekyll comes to, he cuts himself free and steals a key from Poole to free the prisoners. Jekyll brings the group to his old home, where he completes a red serum to separate himself and Hyde into two bodies. Before he can drink it, Poole bursts in, once again forcing Jekyll to down the blue serum so Hyde appears in his stead. After the heroes flee, Hyde ingests the red serum to split himself from Jekyll. He then attempts to choke the life out of his weaker half, but the heroes return to save Jekyll. Poole tries to stop them with his taser, however, Zelena quickly knocks him out with a bolt of her own magic. ("An Untold Story")
