Edward Hyde.
Edward Hyde, or better known as Mr. Hyde, is the dark side of Henry Jekyll, unleashed by use of a potion. Through Jekyll he was a member of the British Paranormal Society then later the B.P.R.D.
Description[]
Hyde is described as a "pale and brutish giant," and has rough, corded hands. Everyone who sees him describes him as giving an impression of ugliness, although he is not somewhat physically deformed. Essentially, he exudes pure evil. Hyde was at first shorter than Jekyll because the evil in man is lesser than the good but as Jekyll began to embrace the debaucherous freedom of Hyde the latter grew larger as a sign that his evil was growing stronger.
Overview[]
Hyde was created out of an experiment by Dr. Henry Jekyll, who wanted to live a wild, carefree existence without losing his respectability. So he decided to unleash his darker side. He created a potion, which allowed this to happen, and he transformed into Edward Hyde, the embodiment of his inner evil.
For a time after this, Jekyll is the respectable doctor by day, then uses the potion to become Hyde and live a life of debauchery and excess by night. Hyde's truly evil nature first made itself apparent when he trampled a small child who had bumped into him in the street. About a year after that, something worse occurred. Hyde, without provocation, savagely beat an old man named Sir Danvers Carew to death.
After this incident, Jekyll determined never to use the potion again. However, Hyde asserted himself and Jekyll began to transform without taking the potion, and he had to brew more to change back into himself. When Jekyll ran out of his materials, he tried procured more to brew the potion again, but he couldn't reproduce it exactly. Unable to go on, Jekyll brewed a lethal poison and swallowed it, but changed back into Hyde before he died.
