Here is a list of my favorite television villains . . . so far:
MY FAVORITE TELEVISION VILLAINS
1. Seska "Star Trek Voyager" (1995-2001) - Actress Martha Hackett portrayed my favorite television villain of all time, the Cardassian spy that had herself surgically altered as a Bajoran in order to infiltrate Chakotay's Maquis cell. Following Voyager's arrival in the Delta Quadrant, Seska was revealed as a spy and she became an ally and lover of the crew's first enemy, Kazon Nistrim leader Maje Cullah.
2. Eobard Thawne aka the Reverse-Flash "The Flash" (2014-Present)/"Legends of Tomorrow" (2016-Present) - My favorite villain from the D.C. Comics Arrowverse franchise is the time traveling speedster and main nemesis of the costume hero, the Flash, Eobard Thawne aka the Reverse-Flash. Actor Tom Cavanagh portrayed Thawne, when the latter was genetically disguised as a scientist he had murdered during Season One of "THE FLASH". Matt Letscher portrayed the character with his true face in various "THE FLASH" episodes and Season Two of "LEGENDS OF TOMORROW". And both are great in the role.
3. Nina Myers - "24" (2001-2010) - Sarah Clarke was excellent as Jack Bauer's second-in-command at CTU Los Angeles, who ended up killing his wife Teri and being exposed as a mole. Following her revelation as a mole, she appeared on the show for another two seasons before she was murdered in cold blood at the hands of her former boss and lover.
4. Wo Fat "Hawaii Five-O" (1968-1980) - Khigh Dheigh was a joy to watch as the Communist Chinese intelligence officer who became the main nemesis of Hawaii State Police chief, Steve McGarrett.
5. President Morgan Clark "Babylon Five" (1993-1998) - For at least three to four seasons, actor Gary McGurk appeared only a few times as the Earth politician who became head of state and dictator of Earth Alliance via political assassination. Despite his limited appearances, Clark proved to be one of the most effective villains in recent television history.
6. Owen Crawford "Taken" (2002) - Joel Gretsch first made a name for himself as the aggressive and ruthless Owen Crawford, an Air Force officer who schemed and murdered his way into control of the private program in charge of investigating aliens that crashed in New Mexico and the U.S. citizens who had been "taken" by said aliens.
7. The Borg Queen "Star Trek Voyager" (1995-2001) - Alice Kriege first became a science-fiction icon in her portrayal of the eader or avatar of the Borg Collective in the 1996 film, "STAR TREK: FIRST CONTACT". But she did memorably reprised her role in the two-part series finale for "Star Trek Voyager".
8. Luther Mahoney "Homicide: Life on the Street" (1993-1999) - Erik Dellums gave a memorable performance in the recurring role as the Baltimore drug lord who made a big impact upon the lives of some of the police detectives in the series - in life and after his death.
9. Elkhanah Bent "North and South Trilogy" (1985; 1986; and 1994) - No fan of the television adaptations of John Jakes' trilogy could ever forget Philip Casnoff's twisted portrayal of the demented West Point cadet-turned Army officer-turned mercenary who made the lives of the Hazards and the Mains miserable before, during and after the Civil War.
10. The Borg Queen "Star Trek Voyager" (1995-2001) - Susanna Thompson also gave memorable performances as the Borg Collective's leader in two two-part episodes from the series. Whereas Kriege had "the voice", Thompson had "the eyes". And both were fantastic.
Honorable Mention: John Goetz "Jericho" (2006-2008) - D.B. Sweeney surprised the hell out of me in his chilling portrayal of the mercenary in post-apocalyptic Kansas, who inflicted a strong impact upon the town of Jericho. His cold-blooded murder of the adolescent deaf-mute Bonnie Richmond sent shock waves throughout the series' fandom.
