Black Hand is a super-villain who carries a Power Rod that can drain other sources of energy, acting as an enemy to Green Lantern. This is later extended to an ability to drain life-force. He is the herald of Nekron and the leader of the Black Lantern Corps. He has also been a member of the Indigo Tribe and the Secret Society of Super-Villains.
Black Hand was created by John Broome and Gil Kane, first appearing in Green Lantern (Volume 2) #29. (1964)
