Scarlet whilst under the control of the Mysterons Captain Scarlet
Mission reference: Instrument of Destruction part 1
Status: Former Mysteron agent
Task: Destruction of Skybase
Additional notes: Captain Scarlet was present on the mission to Mars, and was the surviving member of the two-man team. It is uncertain how he became a victim of the Mysterons, as he does not appear to have been reconstructed in the conventional manner. It is possible that he was reconstructed whilst still on Mars, and that he remained unaware of the fact until the Mysterons required him to act. Scarlet was freed from the Mysterons' control by unknown means.
Captain Black Captain Black
Mission references: Instrument of Destruction parts 1 & 2, Mercury Falling, Circles of Doom, Rain of Terror, Skin Deep, Heist, The Achilles Messenger
Status: Primary Mysteron agent
Task: Destruction of life on Earth
Additional notes: Captain Black was killed by the Mysterons on Mars and reconstructed only when Scarlet failed in his mission to destroy Skybase. He acts as a human vessel for their powers, and acts as their spokesperson on Earth.
McGill Hank McGill
Mission reference: Instrument of Destruction part 2
Status: unknown
Task: commandeering of nuclear fuel
Additional notes: McGill was killed by Captain Black in Instrument of Destruction part 1 and used his haulage business to collect thousands of nuclear fuel rods. It is unknown what has become of McGill.
General Zamatev General Zamatev
Mission reference: Instrument of Destruction part 2
Status: deceased
Task: destruction of Earth
Additional notes: General Zamatev was brought under Mysteron control during the UN briefing regarding the Mysterons. He assisted Captain Black in stockpiling nuclear material and provided a getaway tank for the primary agent. It is presumed that he died in the Dreznik tank when it sank.
The Swarm The Swarm
Mission reference: Swarm
Status: deactivated
Task: destruction of Skybase
Additional notes: The Swarm comprised of many small robots that act together. One single bug infiltrated Skybase and replicated itself into a swarm. The Swarm have the ability to tap into a person's cerebral pathways to gain knowledge. The Swarm had a design flaw that left them susceptible to water, and they were destroyed when Captain Scarlet activated the fire suppression systems on Skybase.
The RAT The RATs
Mission reference: Rat Trap
Status: destroyed
Task: death of Captain Scarlet
Additional notes: The RATs were originally Spectrum research machines, used to collect rock samples from the Martian terrain. They were commandeered by the Mysterons, and attacked the scientists at Base Elysium in order to lure Captain Scarlet to Mars and destroy him once and for all. The RATs were both destroyed.
Commander Lewis Commander Lewis
Mission reference: The Homecoming
Status: deceased
Task: detonation of antimatter reactor
Additional notes: The original Commander Lewis was lost in space on 12th August 2049. He was taken into Spectrum custody after the replicant returned to Earth, and was reunited with his daughter, Lieutenant Green. He was able to make use of the Mysteron power of hypnosis to fool Dr. Gold into performing DNA analysis on his own blood and escape from Skybase before anyone realised the mistake. He almost succeeded in detonating a prototype antimatter reactor at the Space Agency's base in New Mexico. He was killed by Lieutenant Green.
Dr. Kopalski Dr. Celine Kopalski
Mission reference: Mercury Falling
Status: deceased
Task: destruction of Washington DC
Additional notes: Kopalski was still human when she took control of the Mercury shuttle. The Mysterons used her knowledge to their advantage when they took her under their control. Captain Scarlet killed Kopalski by throwing her into a canyon from a moving Rhino.
Gina Martinelli
Mission reference: Skin Deep
Status:
deceased
Task:
ensuring the destruction of Skybase
Additional notes:
Gina was paid as a lookalike thief and committed a robbery using the face of Destiny Angel before she was Mysteronised. After her Mysteronisation, she was the eyes and ears of the Mysterons, ensuring that Captain Scarlet fulfilled his task to destroy Skybase.
Storey
Mission reference: Chiller
Status: in custody
Task: destruction of Skybase
Additional notes: Storey was a human paid to plant a bomb on Skybase. The Mysterons who recruited him promised to end the war once Spectrum were out of the way.
The MIB (Mysterons in Black)
Mission reference: Chiller
Status: Active
Task: Recruitment of human agents
Additional notes: These Mysteron agents were only seen recruiting Storey in Chiller, but the impression is given that they are senior agents, perhaps like Captain Black himself.
Driver
Mission reference: Chiller
Status: deceased
Task: death of Captain Scarlet
Additional notes: Hypnotised into driving his fuel tanker into the diner where Captain Scarlet was being held prisoner. The ensuing inferno should have destroyed Scarlet for good.
Mrs. MacKenzie
Mission reference: Trap for a Rhino
Status: deceased
Task: capture of a Spectrum Rhino & destruction of Grampian Power Station
Additional notes: Mrs. MacKenzie was allowed to see the Mysterons and contact the police before she was killed. Considering that she's a little old lady, she's pretty strong - able to throw Harmony across a room and pin Scarlet to the ground. She fell to her death once Johnson had stolen the Rhino.
Cadet Johnson
Mission reference: Trap for a Rhino
Status: presumed deceased
Task: capture of a Spectrum Rhino & destruction of Grampian Power Station
Additional notes: Johnson was a Spectrum cadet training with Harmony Angel when he was Mysteronised. He stole a Rhino from Captain Scarlet and almost succeeded in destorying the Grampian Power Station. He was (probably) killed when Scarlet crashed a Hummingbird into the Rhino, although his death is not confirmed on-screen.
Rottweiler
Mission reference: Heist
Status: unknown
Task: killing a Vampire pilot
Additional notes: Probably chosen because it could infiltrate a top-security base without suspicion. Could have been a guard dog, we never find out. Poor mutt only has about 5 seconds of screen-time.
Pilot
Mission reference: Heist
Status: deceased
Task: distracting Spectrum long enough that the Heavies can kidnap Victoria Gray.
Additional notes: He's obviously enough of a throw-away character that no-one thought we would notice that he appears to be Scarlet's identical twin brother! Mysteronised by the Rottweiler and dies in a blaze of glory when he is shot down by four Spectrum Angels.
Heavy One
Mission reference: Heist
Status: in custody
Task: Kidnapping Victoria Gray & keeping tabs on Colonel White.
Additional notes: Appears to be human, and unaware of Black's true nature and/or motives. Is run off the road by Scarlet and Blue.
Heavy Two
Mission reference: Heist
Status: deceased
Task: Kidnapping Victoria Gray & ensuring Spectrum's implication in the Great Train Robbery.
Additional notes: Starts off as human, but when he gets cold feet, he is Mysteronised by Black. Colonel White traps him in a Rhino and drives it from a railway bridge.
Astrid Winters
Mission reference: The Achilles Messenger
Status: deceased
Task: passing information to Spectrum
Additional notes: Astrid Winters was reconstructed by a Mysteron who did not agree with the war, and pledged her support to Spectrum. She was killed by Captain Black before she could tell anyone what the Achilles heel of the Mysterons is.
