Leader is the Fulcrum handler for Dr. Jill Roberts. Little is known about him, not even his real name.
Leader is a tough, hardened operative. It is currently unknown what Fulcrum intended to do with Castle once they took control, however, his position overseeing the operation indicates he is ranked somewhere above an ordinary field operative. The incident is the first confirmed instance of two Fulcrum agents working in tandem on the same operation. Leader is a talented—and in his own words devious—strategist, and arranged his own capture to gain access to Castle by using Chuck's feelings for Jill against him.
Leader is shown to be ruthless and very skilled in hand to hand combat, as he is able to hold his own and even gain the upper hand against John Casey. He is eventually taken down by a surprise attack from Big Mike.
