William Hand (New Earth)

Black Hand (real name William Hand) is a DC Comics supervillain and a recurring foe to Green Lantern. He first appeared in Green Lantern v2 # 29 (June 1964) and was created by John Broome and Gil Kane.

An inventive genius, with a penchant for speaking in hoary old clichés, Hand's most noteworthy invention is a device that can absorb the residue of Green Lantern power ring energy from any object that it has touched. Black Hand can then use this energy much the same way that Green Lantern does. In addition to Green Lantern Hal Jordan, Black Hand has also done battle with the second Flash, Barry Allen.

The Black Hand once tried to go straight, opening a business consisting of skin flicks. But when his theatre was visited by Guy Gardner and Ice Maiden, then of the JLA, he took it as an assualt to his business and tried to confront Guy. He suffered a mental breakdown during this encounter, but Guy continued to beat him none the less.
