Dr. Oliver Mitchell (portrayed by Richard Gilbert-Hill) is a minor character from the TV series Charmed, appearing in the Season One episode "The Truth is Out There... And It Hurts".
He was a mortal scientist that would one day help to create a vaccine that would wipe out warlocks.
In 1998, Dr. Mitchell was confronted in a parking lot by Gavin, a warlock from the future. Gavin claimed to have read all his work, even one that wasn't even published yet. He then told Dr. Mitchell that his work would help finding the vaccine and proceeded to kill him by burning a hole in his forehead.
