In The Black Wiki:Bureaucrats

The Bureaucrat status is generally granted to senior members of well established editing communities. They have all of the permissions of an administrator, plus the ability to promote registered users to the administrator level. This level of responsibility is also granted on Gamepedia wikis to specified Game company representatives when they have indicated a desire to be actively involved in the wiki's growth and development.

Users chosen to be Bureaucrats, have demonstrated over time their knowledge of how wikis work, their sensible and balanced judgment while interacting with members of the community, and their trustworthiness to not abuse their position.

Bureaucrat's are expected to be the final mediator in user disputes when administrators are either unable to resolve a situation, or are personally involved in the dispute. Bureaucrat's who are inactive for an extended period of time will lose their status.
