~ Edward Nygma before seeking his revenge on Bruce Wayne for rejecting his mind manipulation invention.
Riddle me this, riddle me that. Who's afraid of the big, black, Bat?
~ Ed Nygma/The Riddler
Edward Nygma, better known as The Riddler, is one of the three main antagonists of the 1995 superhero film, Batman Forever, the others being Two-Face and The Scarecrow.
Edward Nygma starts out as an employee researcher at Wayne Enterprises who is obsessed with Bruce Wayne. Nygma wanted to use Wayne to test out his invention which was capable of beaming a TV signal into someone's brain. But Bruce rejects his invention and tells Nygma that it "raises too many questions".
Angered by Bruce's rejection, Nygma goes to his supervisor Fred Stickley, and tests it on him. When Stickley discovers Nygma's clandestine overtime, Nygma knocks Stickley unconscious, ties him to a chair, and then uses him to test his device, discovering that he can use it to absorb people's knowledge. Realizing Wayne was right about it being mind manipulation, Stickley fires Nygma, but Nygma murders Stickley, doctors the security tapes to make Stickley's death look like a suicide, and then resigns from Wayne Enterprises. Everyone except Bruce is convinced that it was a genuine suicide.
