Evil Ash (Evil Dead)

Evil Ash is a villain in the Evil Dead movies and is none other than Ash Williams himself, or - to be more accurate - the dark-half of Ash's personality given corporeal form by the evil spirits that he has spent his life battling (known as Deadites in the series).

Evil Ash began his "life" as an entity known as Bad Ash, who appeared out of a mirror during the events of Evil Dead II and proceeded to torment his heroic counterpart - trying to drive him mad - indeed the whole Bad Ash scenario was suggestive of Ash beginning to lose his sanity and could arguably be seen as Ash battling his inner-demons on a literal level.

At any rate after a confrontation of two Bad Ash is "killed" by the original Ash and is never heard of again until the plot of Army Of Darkness - by which time Bad Ash resurrected himself as the more powerful Evil Ash, this incarnation was completely immortal and made himself the leader of the Deadite armies in direct opposition to his heroic counterpart - who was reluctantly acting as a hero to a medieval army of his own (due to time-travel related mishaps).

Evil Ash fought with Good Ash over the course of the movie and became more hideous as varied violent acts (which would be fatal to most) simply disfigured his already rotting body further - despite the damage he took over the course of the film he was driven by a crazed zeal to retrieve the Necromonicon, the Deadite's ultimate source of power, from the human settlement Ash was defending.

Evil Ash stormed the settlement with his titular "army of darkness" and a war broke out, with regular Ash's help the tide was turned in humanity's favor - however Evil Ash proved more formidable and via brute strength and sword made his way towards the Necromonicon but the original Ash sets him ablaze, yet even this is not enough and a now skeletonised Evil Ash battles his heroic counterpart again: in an ironic twist regular Ash cuts off Evil Ash's right hand before tossing him onto a lit bag of gumpowder resting on a catapult, regular Ash cuts the cord and sends Evil Ash catapulting to an explosive demise.

However true to his immortal nature Evil Ash returns in Evil Dead: Hail To The King - for some reason in this setting he has developed shape-shifting abilities and the ability to launch fireballs: he is also a recurring antagonist in the Evil Dead comics, as the dark half of Ash made flesh (much like the movie) - in the comics he is utterly obsessed with killing his "pure" half.
