William Raines is a character on The Pretender.
Dr. William Raines was the leader of several projects in the Centre, including projects like the Red Files responsible for the events that have helped shape Jarod, Angelo, Kyle, Mr. Lyle, Miss Parker and 3 others; and Gemini that created Jarod's clone. Known for the trademark squeaking of the wheels on his ever-present oxygen tank, Raines is one of the most feared people at the Centre.
He was raised with foster parents. He was born Abel Parker and was adopted by the Raines family.
- Edna Raines - Raine's wife.
- Annie Raines - Raine's deceased daughter, whose killers Jarod will track down.
- Miss Parker - Dr. Raines is allegedly the real father of Miss Parker, according to a discovery made by Broots in Island of the Haunted, the final TV movie. They shared the same affection towards smoking, a habit that she discontinued mid-series.
- Sydney - a constant rivalry in almost every project especially over Jarod, mostly about which projects to use him and how.
It turns out later, in the films, that Dr. William Raines, is actually an alias, last name taken from the adoptive family (Raines) and his real name is Abel Parker and he is the brother of Mr. Parker.
