Mr. Edward Underwood was the adoptive father of Freddy Krueger. He presumably took in Freddy at a young age when the boy's biological mother gave him up for adoption.
He was portrayed by singer-songwriter, Alice Cooper.
A severe alcoholic, Mr. Underwood abused Freddy both verbally and physically. His preferred method of beating the boy was apparently being whipping with a belt.
Once he became a teenager, Freddy, fed up with his foster father's abuse, murdered the old man when he came home drunk one day, and laughed off Mr. Underwood's blows before he stabbed him in the eye with a straight razor as revenge, a memory which Freddy's daughter, Maggie Burroughs, later witnessed after she entered her father's mind years later.
