F.E.A.R. is behind many plots over the course of the series, frequently employing other super villains to perform nefarious tasks. The organization was seemingly defeated for good and its leader arrested, but it occasionally resurfaced without any explanation. He has many weapons at his disposal. Unknown what F.E.A.R stands for.
