Dr. Jekyll and Mr. Hyde

Origin
The dual title character, a doctor who has covered up a secret life full of cruel deeds. He feels as if he is constantly battling within himself between what is good and what is evil, and is pushing away people dear to him. After drinking a potion of his own creation, Jekyll is transformed into the cruel, remorseless, evil Edward Hyde, representing the hidden side of Dr. Jekyll's nature brought to the fore. Dr. Jekyll has many friends and has a friendly personality, but as Mr. Hyde, he becomes mysterious, violent, and secretive and as time goes by, Mr. Hyde grows in power. After taking the potion repetitively, he no longer relies upon the potion to unleash his inner demon.
