Admiral Bruce Winnick was one of the members of Oversight. His codename was Hades.
In "Pandora" he was present during a meeting with Percival Rose.
In "Sanctuary" he met with Madeline Pierce, Phillip Ramsey and David Collins to discuss about Nikita. They have decided that the best option is the "Clean Sweep". Patrick Miller and some other men attacked the members of the Oversight to blackmail Amanda into releasing Percy.
