H.I.V.E.

H.I.V.E. is a mysterious organization that hired Deadshot to kill Andy Diggle.

Trivia

 * H.I.V.E. stands for Hierarchy of International Vengeance and Extermination.
 * In some versions, notably the Teen Titans cartoon version, H.I.V.E. is lead by Brother Blood; they also frequently contract Deathstroke for work, and in the aforementioned Titans cartoon were contracted by Slade Wilson. Given that both these individuals are present, with their authority positions switched, it is possible that the Blood Cult is actually H.I.V.E..
