The Night King (new entry - making it 18 types)
This student says very little - almost nothing in fact. This silence could cause problems in committee meetings, qualifying exams, defenses, and presentations; yet the student has such as commanding (intimidating even) presence, that no one dares to criticize. This student has a remarkable ability to resurrect old, presumed dead, data and manuscripts, which are rapidly converted into published papers that quickly steam-roll related papers by other groups. The supervisor hopes it isn't all a thin veneer that can be quickly punctured by someone brave enough to challenge the core principles and methods behind the work.
