Dr. Michael Slovak

First appearance: The Mind's Eye (2015)

A drifter with telekinetic powers runs afoul of the head of the Slovak Institute of Psychokinesis, an organization set up to help telekinetically powered individuals. But does the The head of SIP have other more nefarious plans? You can count on that, wouldn't be much of a movie other wise.

This is the second movie from Joe Begos, director of Almost Human.

Darryl Revok

First appearance: Scanners (1981)

Turns out there's a real weird birth defect associated with the old analgesic Ephemerol. Psychic powers! Now there's two groups of people looking for these psychics, known as Scanners. One is ConSec and it's owner Dr. Paul Ruth, the guy who invented Ephemerol and tested it on his wife,  who is hoping to train these psychics to uses their powers for espionage. The other is lead by Darryl Revok, a scanner, who's using his company Biocarbon Amalgamate to send more Ephemerol to pregnant women in hopes of creating an army of psychic babies! Can former bum and troubled Scanner, Cameron Vale, help ConSec stop Revok from creating an army of fellow Scanners?
Most people know it as "That movie with the exploding head."
Another strange Canadian sci-fi/horror flick from director David Cronenberg from the 1980s. A little slow in parts but worth seeing for its strange mix of spy and monster movie conventions.
I think it might be my favourite Cronenberg movie.

Sadako

First appearance: Ringu (1998)

A weird psychic girl gets her revenge through a cursed video tape. Watching the tape means you'll die in seven days. Why does she want to kill you? It has something to do with being thrown in a well where she died. Certain aspects of the plot are similar to the amaing "The Changling" (1980).

Remade in the U.S. into a stylish yet boring movie.
