[[folder: The Tracys]]
!The Tracy Family in general
* AcePilot: All of them are aces at manning their own vehicles. They are skilled enough to fly each other's if need be, such as Alan piloting Thunderbird 1, Virgil piloting Thunderbird 3 and Scott piloting the Fireflash, a plane that isn't even part of the International Rescue fleet.
* BadassCrew[=/=]BadassFamily: Each one of the Tracys have a background specialising in the roles they play in a rescue.
* ExpansionPackPast: According to WordOfGod, they all have had impressive careers before forming International Rescue. Jeff was an astronaut, Scott was an air force pilot, Gordon was an Olympic swimmer, Alan was a race car driver, etc.
** MultipleChoicePast: As noted in ContinuitySnarl, most of the guides and expanded universe content concerning the team's past exploits contradict each other.
* ImprobableAimingSkills: All of them are excellent shots, but Virgil and Gordon stand out.
* {{Irony}}: Scott's background was in the USAF, while his namesake (Scott Carpenter) was an aquanaut. Gordon takes part in the underwater missions and [[ExpansionPackPast spent a year commanding a deep-sea bathyscaphe]]. Gordon Cooper was in the USAF.
* KnightInShiningArmour: The moment they show up, most problems will be solved.
* LanternJawOfJustice: Runs in the family.
* [[NiceGuy Nice People]]: Some of the nicest.
* ThemeNaming: All five Tracy brothers were named after members of the Mercury Seven, a famous crew of dashing American astronauts.
* ScienceHero: They use science, awesome vehicles and gadgetry to save the day.

!Jeff Tracy
Voiced by: Peter Dyneley (original), Guillermo Romano (Latin American Spanish dub, series), Creator/SalvadorDelgado (Latin American Spanish dub, movie); Played by: Creator/BillPaxton

Ex-astronaut and wealthy philantropist. Patriarch of the Tracy family and founder and leader of International Rescue.

* AcePilot: Implied as he was a colonel in the USAF before becoming an astronaut.
* AdaptedOut: Absent from the [[WesternAnimation/ThunderbirdsAreGo remake]].
* AFatherToHisMen: Literally and figuratively. He is compassionate and fatherly not only to his actual sons, but to most people he meets.
** Bill Paxton actually became this during filming of the 2004 movie to the actors playing the other Tracys.
* BadassBaritone: Peter Dyneley, his VA, had one by default.
* BigGood: The founder and head of International Rescue.
* BigShutUp: In "[[Recap/ThunderbirdsS1E22BrinkOfDisaster Brink Of Disaster]]", Jeff does this to conman Warren Grafton when Grafton complains that the out-of-control monotrain is going too fast.
* CigarChomper: Often seen with a cigar.
* ComicBookFantasyCasting: Jeff's design was based off of Lorne Greene.
* CoolOldGuy: He was in the USAF and was an astronaut before starting International Rescue.
* {{Expy}}: Of [[{{Series/Bonanza}} Ben Cartwright]]
* {{Fiction500}}: Big time. All of International Rescue - the island, the vehicles, the world-wide spy network - was funded by his past exploits as an astronaut.
* GentlemanSnarker: He has his moments. The BigShutUp was pretty memorable.
* GoodParents: He's a loving dad towards his sons.
* TheIdealist: Played straight. Jeff Tracy made his incredibly ambitious ideal of a global rescue organization come true by virtue of his wealth and Brains' genius.
* MissionControl: He stays at HQ and commands the International Rescue teams.
* NiceGuy: he's intelligent, kind and has a good sense of humour
* NonActionGuy: Due to being a RetiredBadass, he works MissionControl.
* OverprotectiveDad: A strange example for a man who routinely sends his kids into danger. Explored in "[[Recap/ThunderbirdsS2E1AtlanticInferno Atlantic Inferno]]", when he goes on vacation and temporarily hands leadership over to Scott. Scott does well enough, but he can't stop himself from constantly worrying and meddling.
* PragmaticHero: One of Jeff's rules for International Rescue is that it focus on actually saving people and preventing disasters, instead of catching the criminals or terrorists who cause the problems. He does avert this on a couple of occasions, however.
* RetiredBadass: Worked as a colonel in the USAF and then became an astronaut who landed on the moon.
* RichIdiotWithNoDayJob: The part he plays.
* TeamDad: Both literally and figuratively.

!Scott Tracy
Voiced by: Shane Rimmer (original), Luis Bayardo (Latin American Spanish dub, series), Sergio Gutiérrez Coto (Latin American Spanish dub, movie); Played by: Philip Winchester

Eldest son of Jeff Tracy and principal pilot of Thunderbird 1, a hyper-fast reconnaissance vehicle. With his moblie base, he oversees and leads many operations. He also co-pilots Thunderbird 3 together with Alan.

* ADayInTheLimelight: Gets plenty of screentime, but "[[Recap/ThunderbirdsS1E10TheUninvited The Uninvited]]" is completely his episode.
* TheAce: He was an AcePilot in the USAF.
* AcePilot: Scott was decorated for valour by the USAF.
* BewareTheNiceOnes: In "[[Recap/ThunderbirdsS1E20MoveAndYoureDead Move - And You're Dead]]", Scott in Thunderbird 1 [[spoiler:shot at the villains who were responsible for putting Alan and Grandma Tracy on a bridge with a bomb on it.]]
* BigEater: Loves to help himself to some of Grandma's apple pie. He eats an entire pie by himself in "The Uninvited".
* TheCaptain: While Dad is in overall charge, Scott takes the place of field leader.
* CaptainObvious: Occasionally. He is always first on the scene and has to bring his brothers up to speed, pointing out every obvious detail.
* ColourCodedCharacters: He has a light blue sash.
* ComicBookFantasyCasting: To an extent. His puppet's features were based off of Sean Connery.
* TheComicallySerious: Being in the USAF has helped him keep a cool head, even in the more comedic moments, such as the ending of "Cry Wolf".
* CoolShip[=/=]CoolPlane: ''Thunderbird 1'', piloted by Scott, is a hypersonic aircraft that is reminiscent of the X-15 and the [=MiG=] 19 and 21, designed for getting to the crisis scene as fast as possible for information.
* DeadpanSnarker: "The things I do for International Rescue..."
* MissionControl: The field agent variety, as he has TB1 scope out the Danger Zone.
* MrExposition: He is the first at the Danger Zone, and has to assess the danger and figure out which equipment is needed.
* NiceGuy: Scott is quite a friendly guy.
* NumberTwo: Jeff is the BigGood of the series, while Scott is the field commander. He plays this role somewhat to Alan when acting as co-pilot to Thunderbird 3.

!John Tracy
Voiced by: Ray Barrett (series and ''Thunderbirds Are Go''), Keith Alexander (''Thunderbird 6''), Jorge Lapuente (Latin American Spanish dub, series), Luis Alfonso Mendoza (Latin American Spanish dub, movie); Played by: Lex Shrapnel

Second son of Jeff Tracy and operator of Thunderbird 5. He ostensibly shares this duty with Alan, which would also make John a principal pilot of Thunderbird 3, [[TheUnfavorite but...]]

* ADayInTheLimelight: He gets into action in a grand total of one episode: "[[Recap/ThunderbirdsS1E19DangerAtOceanDeep Danger At Ocean Deep]]". Even then, he didn't do much.
* AllThereInTheManual/ExpansionPackPast: John is said to be the quietest and most intellectual of the brothers. Part of his background is his expertise in electronics and (fittingly) astronomy. Regarding the latter, he has written and published four textbooks and has also discovered the Tracy Quasar system.
* ComicBookFantasyCasting: John's facial features are based on those of actor Charlton Heston and pop star Adam Faith.
* TheGenericGuy: He only serves as a space monitor and is pretty much a two-dimensional character, despite his ExpansionPackPast stating he is a professional astronomer who wrote textbooks and discovered a quasar.
* HeroOfAnotherStory: John claims he has been on "a dozen or so" rescues, despite "[[Recap/ThunderbirdsS1E19DangerAtOceanDeep Danger At Ocean Deep]]" being the only episode in which we see him take part in one.
* NiceGuy: He's somewhat friendly.
* TheUnfavorite: Creator/GerryAnderson hated this character with a vengeance. To what extent? He was initially unimpressed with the design of Thunderbird 5, but he approved it anyway so that John would [[KickedUpstairs be stuck in space]] for most of the series.

!Virgil Tracy
Voiced by: David Holliday (Series 1), Jeremy Wilkin (Series 2 and movies), Miguel Córcega (Latin American Spanish dub, series), Creator/JoseGilbertoVilchis (Latin American Spanish dub, movie); Played by: Dominic Colenso (2004 film)

Third son of Jeff Tracy and pilot of Thunderbird 2. As such, he is often right in the heart of the action.

* BadassBaritone: Out of all the Tracy brothers, his voice is the deepest. As far as badass goes, he handles the heavy lifting.
* BashBrothers: With Scott. More often than not, the two of them handle the rescue of the week together. They work well as a team and clearly have a strong bond.
* TheBigGuy: Not so much his character, as his plane, ''Thunderbird 2'', was the powerhouse of International Rescue. [[WesternAnimation/ThunderbirdsAreGo The remake]] took this trope and ran with it.
* ColourCodedCharacters: His sash is a canary yellow.
* ComicbookFantasyCasting: Virgil's facial features are based on those of actor Robert Reed.
* CoolShip[=/=]CoolPlane: ''Thunderbird 2'', piloted by Virgil, is a giant less-hypersonic-but-still-fast lifting-body transport for moving the gear that ''Thunderbird 1'' called for. (This one is unsurprisingly the most frequently seen of the lot, appearing in both (all right, all three) movies and all but one episode of the TV show.)
* ExpansionPackPast: He is a graduate of the Denver School of Advanced Technology. It gave him the experience and knowledge to become the pilot of Thunderbird 2 and its many complex auxiliary rescue vehicles, such as the Mole, the Firefly [[MyFriendsAndZoidberg and the Monobrake]].
* FriendToAllChildren: In "[[Recap/ThunderbirdsS1E18CryWolf Cry Wolf]]" he takes part in rescuing two kids in a mine.
* HeroicAmbidexterity: He is shown painting with both his right and left hands.
* HiddenDepths: Likes literature, painting and playing piano.
* ImprobableAimingSkills: Second only to Gordon.
* JackOfAllTrades: Somewhat regarding his ability to operate many of the pod vehicles, his background in several arts, and being an engineer.
* ManlyManAndSensitiveGuy: Sensitive Guy to Scott's Manly Man. Scott is the straight talker with military training, while Virgil is soft-spoken and likes to play the piano.
* NiceGuy: Virgil shares a compassionate side of responsibility like his brothers, never placing technology above human needs, even if it means placing his own life in danger.
* {{Troll}}: He has Alan stand with his racing trophy for ages so he can do a painting, [[http://vignette2.wikia.nocookie.net/thunderbirds/images/b/bc/Move777.png/revision/latest?cb=20150428225422 This is the result.]]

!Gordon Tracy
Voiced by: David Graham (original), ? (Latin American Spanish dub, series), Creator/YamilAtala (Latin American Spanish dub, movie); Played by: Ben Torgersen

Fourth son of Jeff Tracy and principal pilot of Thunderbird 4.

* ADayInTheLimelight: Single-handedly saves not one but two Fireflashes in "[[Recap/ThunderbirdsS1E12OperationCrashDive Operation Crash-Dive]]".
* ColourCodedCharacters: His sash is orange.
* CoolBoat: Thunderbird 4 is a submarine that is decked out with multiple gadgets.
* DeadpanSnarker: His "thing" was being a bit more mouthy than the other brothers.
* ExpansionPackPast: Gordon used to be a Olympic champion at the butterfly stroke and served at this universe's version of the World Aquanaut Security Patrol (the main organisation from ''Series/{{Stingray|1964}}'' however it is unknown if this is a shard universe) and commanded a deep sea self-propelled submersible and spent a year beneath the ocean investigating marine farming methods. (Similar to ''Scott's'' namesake) On another note, he was in a near lethal hydrofoil speedboat crash at over 400 knots. He also designs SCUBA equipment.
* FightMagnet: Gets into no less than three shootouts during the series.
* HotBlooded: Usually lighthearted, he tends to get pretty exited in action compared to his brothers. For instance, when [=TB2=] is grounded for repairs during an emergency, Gordon seriously proposes piloting [=TB4=] on a trans-oceanic trip and the rest of the family have to gang up on him to make him realize that idea is dangerous and completely impractical.
* ImprobableAimingSkills: Gordon was recognised as the best marksman on the team, though, and was often utilised when something needed aiming, eg. firing the cable from ''Thunderbird 2'' into the Zero X in the first movie.
* MadeOfIron: Implied in his ExpansionPackPast where he survived a nasty hydrofoil speedboat crash at 400 knots.
* NiceGuy: Gordon is good-natured, high spirited, and possesses a strength and resilience that makes him a well respected member of the IR organisation.
* NoIndoorVoice: Especially during "[[Recap/ThunderbirdsS1E6DayOfDisaster Day Of Disaster]]", when Brains needs him to be quiet. Helps that he is voiced by David Graham, who also voiced [[Series/DoctorWho the Daleks]].
* RealAwardFictionalCharacter: Gordon is an Olympic champion at the butterfly stroke.
* ThisLooksLikeAJobForAquaman: As the underwater craft and smallest Thunderbird, [=TB4=] was used only occasionally. He takes turns with Alan and Brains for backup on [=TB2=]. There was that time he fought a saboteur on board a supersonic airliner and had to make a quick fix with his bare hands.

!Alan Tracy
Voiced by: Matt Zimmerman (original), Miguel Córcega (Latin American Spanish dub, series), Aarón Díaz (Latin American Spanish dub, movie); Played by: Brady Corbet

Youngest son of Jeff Tracy, principal pilot of Thunderbird 3, and all-round crewmember to the point of being a jack-of-all-trades. He often comes along in Thunderbird 2, flies Thunderbird 1 when Scott is unable to do so and shares duties with John monitoring Thunderbird 5.

* ADayInTheLimelight: "[[Recap/ThunderbirdsS1E20MoveAndYoureDead Move - And You're Dead]]" is his main one, but he got plenty of screentime as the series went on.
* {{Bishounen}}: He's exceptionally pretty, although he still has the [[LanternJawOfJustice Tracy jawline]].
* ColourCodedCharacters: His sash is off-white.
* ComicBookFantasyCasting: The reason he bears the most resemblance to Virgil is because his facial features are also based on Robert Reed.
* CoolShip: Thunderbird 3 is a SSTO rocket used for space missions.
* CrazyJealousGuy: Alan can be quite upset when Tin-Tin shows interest in another man. This is especially evident in "End of the Road" and "Ricochet". To add insult to injury, in both episodes Alan ends up having to rescue his rival.
* DoggedNiceGuy: He has a crush on Tin-Tin, especially evident in ''End Of The Road''. The romance never really takes off, as the series had other things on its mind.
* ExpansionPackPast: He was involved in an experimental rocket project; during this, there was a near-catastrophic accident, resulting in an unexpected disaster. Despite this accident, he went on several lunar missions. He was once a champion racecar driver and for sport, Alan enjoys rock climbing and running, as reinforced in his enthusiasm in exploring Tracy Island's more inaccessible parts, which is his constant source of adrenaline-inducing activity.
* KidAppealCharacter: Alan isn't this trope for being the youngest of the Tracy brothers at Twenty-One. He happens to have a job coveted by most kids- being an astronaut. It helps that he was also a professional race car driver and a rock climber. He is also given a fair bit of spotlight despite his main Thunderbird not seeing much use. Despite being the more moody of the brothers, he avoids being TheScrappy sort of KidAppealCharacter.
* LovableJock: He's the most sporty of the Tracy siblings,(race car driver, and rock climbing) and he's a nice guy.
* MeaningfulName: Like John, it is more meaningful as he is actually an astronaut like his namesake. (Alan Shepherd)
* NiceGuy: Alan is caring and deeply romantic and though the youngest of his brothers, displays a great maturity in his responsibly to the organisation.
* SpotlightStealingSquad: All movies, both the puppet ones and (particularly) the live-action ones, focused on him.
* ThisLooksLikeAJobForAquaman: Suffers from this even more than Gordon, as [=TB3=] is the most rarely-seen Thunderbird. He gets compensation as he comes along with Virgil more often.

!Grandma Tracy
Voiced By: Christine Finn (original), Sylvia Gray (Latin American Spanish dub, series)

Mother of Jeff, grandmother of the five Tracy Brothers. She lives in her own house at first, but later in the series moves in with Jeff and the boys. Usually a background character.

* ADayInTheLimelight: "[[Recap/ThunderbirdsS1E20MoveAndYoureDead Move - And You're Dead]]", which was meant to be her introduction, but see below...
* ContinuitySnarl: Played with. She was originally not going to appear until "[[Recap/ThunderbirdsS1E20MoveAndYoureDead Move - And You're Dead]]", episode 9 in production order. However, when the episodes were lengthened to an hour, she was added in the extra scenes shot for many of the previous episodes.
* GrannyClassic
* NiceGirl: She's a kindly Grandmother.
* NoNameGiven: Everyone refers to her as either mother, grandma or Mrs. Tracy.


[[folder: The Tracy Island Crew]]
Voiced by: David Graham (original), Pedro D'Aguillón Jr. (Latin American Spanish dub, movie); Played by: [[Film/RevengeOfTheNerds Anthony]] [[Series/{{ER}} Edwards]]

The [[IncrediblyLamePun Brains]] of the team. Designer and engineer of the Thunderbirds machines, as well as many other cool vehicles and revolutionary innovations.

* ADayInTheLimelight: He plays the protagonist in "[[Recap/ThunderbirdsS1E8DesperateIntruder Desperate Intruder]]", which also develops his character. He also gets to save the day in "[[Recap/ThunderbirdsS1E11SunProbe Sun Probe]]" and "[[Recap/ThunderbirdsS2E4LordParkersOliday Lord Parker's 'Oliday]]".
* TheAtoner: In "[[Recap/ThunderbirdsS1E8DesperateIntruder Desperate Intruder]]", he wants to atone for endangering the mission by going after the treasure himself. Of course, this ends up causing more trouble.
* BadassBookworm: As the series progresses, he comes along with the brothers more often, and proves to be as competent and fearless as they are. [[spoiler: He eventually becomes the pilot of Thunderbird 6.]]
* ComicBookFantasyCasting: Brains' facial features are based on those of actor Anthony Perkins.
* ConvenientlyAnOrphan: His parents died in a hurricane that hit Michigan.
* ExactlyWhatItSaysOnTheTin: He's the brains.
* ForeheadOfDoom: His puppet has a truly enormous forehead. Probably overlaps with MyBrainIsBig.
* GadgeteerGenius
* MrExposition: As far as the scientific aspects of the series goes, Brains lends some context.
* NiceGuy: Very well mannered and friendly.
* OmnidisciplinaryScientist: Although engineering is his main forte, he is shown to be into chemistry in "[[Recap/ThunderbirdsS1E19DangerAtOceanDeep Danger At Ocean Deep]]" and archaeoligy in "[[Recap/ThunderbirdsS1E8DesperateIntruder Desperate Intruder]]".
* OnlyKnownByTheirNickname[=/=]EveryoneCallsHimBarkeep : His real name is never mentioned in the series. Everybody just calls him Brains. He occasionally goes by the alias of "Hiram K. Hackenbacker", which the 2004 film used as his real name. In the 2015 series, his name is Hiram again.
* ThePerfectionist: Brains is stated to never be fully satisfied with his work.
* ScienceHero[=/=]NerdActionHero: In addition to his merits as a scientist, he is a competent rescuer in his own right.
* SmartPeopleWearGlasses: The only bespectacled member of the main cast, and by far the cleverest.
* SpeechImpediment: Ah, ah, speaks with ah, ah, a bit of ah, ah, a s-s-stammer.
* {{Technobabble}}: Most of his "explanations" don't make much sense.
* TechnoWizard: He designed the Thunderbirds craft and all of the gadgets.
* TheSmartGuy: He is an engineering genius.

Voiced by: David Graham (original), Fernando Rivas Salazar (Latin American Spanish dub, series); Played by: Bhasker Patel

Housekeeper of Tracy Island. He once had his life saved by Jeff Tracy and is eternally grateful for the fact. He does his bet... but there's the downside of him being mindcontrolled [[TheMole occasionally spying on International Rescues on behalf of The Hood]], his evil older brother. It is unclear whether he is entirely aware of this.

* TheButlerDidIt: Although he does it under influence of The Hood, and probably doesn't even realize himself what's going on.
* ExpansionPackPast: He is an expert botanist and was developing synthetic food when he met Jeff.
* ExtremeDoormat: He's incredibly servile and humble towards everyone else, although in "[[Recap/ThunderbirdsS1E14TheMightyAtom The Mighty Atom]]" he is seen to stand up for himself against Parker.
* IOweYouMyLife: He and his daughter were saved by Jeff before the series starts, though we don't know exactly how.
* TheMole: Unwillingly, as Hood is his half-brother, and has psychic influence over him.
* NiceGuy: Though it gets to the point where he's a doormat.
* WeakWilled: The Hood has the poor old guy in his power. Kyrano is utterly powerless to stop him, and not brave enough to tell Jeff or anyone else about this.
* SupremeChef: He was head chef at the Paris Hilton once.
* VagueAge: His birth certificate was lost.
* YesMan: To Jeff Tracy. The man can do no wrong in his eyes.
* ZombieInfectee: He ''never'' cares to tell anyone about his connection to The Hood. As the series was cancelled, the plotline never got resolved.

!Tin-Tin Kyrano
Voiced by: Christine Finn (original), Amparo Garrido (Latin American Spanish dub, series), Sherlyn González (Latin American Spanish dub, movie); Played by: Music/VanessaHudgens

Kyrano's beautiful daughter, who has been taken under the wing of International Rescue and lives on Tracy Island. She's ostensibly Brain's assistant technician, although she performs many roles.

* AcePilot: In ''[[Recap/ThunderbirdsF2Thunderbird6 Thunderbird 6]]'', she's doing some impressive stunt flying to mess with Parker.
* BrainyBrunette: She's dark haired and the assistant of Brains.
* TheChick: Very much plays the role of the caring one. She is always trying to calm and reassure everyone.
* DistressedDamsel: From day one. She's been one of the rescuees in no less than six episodes, plus "Thunderbird 6".
* ExpansionPackPast: She has degrees in higher mathematics, advanced technical theory, and engineering.
* FauxActionGirl: She is a full-blown member of IR and even has a uniform (seen twice). Even then, she usually ends up in need of rescue. A notable exception occurs in one novel, in which she rescues Scott and Virgil from her uncle.
** It should be noted that she mostly works with Brains, and is fully capable too with her background in engineering.
* GoodWithNumbers: Tin-Tin has a degree in higher mathematics.
* HiddenDepths: Her educational background involves [[GoodWithNumbers higher mathematics]], advanced technical theory and engineering. She is also shown to be a pilot, SCUBA diver, and skiing (both the regular and water).
* MasterOfTheMixedMessage: To Alan. They are often seen in loving embrace one moment, the next she sees another guy and forgets all about Alan.
* TheMedic: Plays this role in "[[Recap/ThunderbirdsS1E10TheUninvited The Uninvited]]" nursing Scott back to health.
* NeutralFemale: Although she is often involved with IR missions in some capacity, she mostly just hangs around.
* NiceGirl: She's very nice.
* SingleWomanSeeksGoodMan: Her relationship with Alan is rather ambiguous, and she often falls for other men.
* TheSmurfettePrinciple: The only female inhabitant of the island, save for Grandma Tracy.

[[folder: Lady Penelope and Parker]]

!Lady Penelope Creighton-Ward
Voiced by: Sylvia Anderson (original), Queta Lavat (Latin American Spanish dub, series), Itatí Cantoral (Latin American Spanish dub, movie); Played by: Creator/SophiaMyles

London-based Agent of IR, blue-blooded lady, owner of a [[BigFancyHouse fancy house]] and a [[CoolCar fancier automobile]] and EnsembleDarkhorse, Lady Penelope is the heir of British aristocracy and International Rescue's go-to lady for espionage, intelligence and investigation.

* ActionGirl: In the 2004 movie, at any rate; one of the few good elements in the eyes of fans.
* BadassInDistress: She's often a genuinely competent woman who gets captured by the bad guys.
* BigFancyHouse: Her mansion is impressive.
* BlueBlood: She comes from a line of aristocrats.
* ChristmasCake: Supplementary material usually give her age as late twenties or early thirties.
* DependingOnTheWriter: Either a cool, collected badass who takes no shit from anyone, or a spoiled, pompous NeutralFemale who panics as soon as she fears she might get her hands dirty. Most episodes have her lean toward the first, fortunately.
* DrivesLikeCrazy: At first, as seen in "[[Recap/ThunderbirdsS1E13VaultOfDeath Vault Of Death]]". She gets better, as seen in "[[Recap/ThunderbirdsS1E22BrinkOfDisaster Brink Of Disaster]]".
* FashionModel: In both major incarnations she is a fashion-model. Thus she has a groovy 1960's fashion sense (right down to [[CoolCar her pink Rolls-Royce]]), as well as give her reason to pop up anywhere in the world whenever the Tracy family needs her assistance in a mission. She just happened to be attending a show or gala nearby.
* GirlyBruiser: In the 2004 film; she beats the stuffing out of the Hood's lackeys while [[ParasolOfPain wielding a parasol]].
* IAmVeryBritish: The most British character in a British show mostly starring [[FakeAmerican Fake Americans]], Penny combines quite a lot of British stereotypes. She's a posh aristocrat with a cockney butler, lives in a stately home, keeps a StiffUpperLip at all times and loves her tea.
* ImpoverishedPatrician: BigFancyHouse and jewellery collection notwithstanding, it is occasionally implied she's not particularly rich. She gives guests a tour of her home ("[[Recap/ThunderbirdsS1E1TrappedInTheSky Trapped In The Sky]]") and calls on Jeff when someone needs financial help ("[[Recap/ThunderbirdsS1E22BrinkOfDisaster Brink Of Disaster]]", "[[Recap/ThunderbirdsS1E21TheDuchessAssignment The Duchess Assignment]]").
* InkSuitActor: Her appearance was loosely based on Sylvia Andersons', although Sylvia holds she was oblivious to the fact at the time.
* InstantCostumeChange: The 2004 film has her do this frequently, even when she logically shouldn't be able to; this was [[LampshadeHanging lampshaded]] by Creator/JonathanFrakes on the DVDCommentary.
* LadyOfAdventure: A lovely, plucky young woman who loves going on adventures.
* TheMainCharactersDoEverything: Is invariably called out to every mission, no matter where in the world, despite specifically being the London agent. See the episode "[[Recap/ThunderbirdsS1E16TheImposters The Imposters]]" for a good example of this (although she did team up with IR's local agents in the area). The 2004 movie at least somewhat justifies her presence, as Alan, Tin-Tin and Fermat need her help against the Hood (with the other Tracys having been trapped aboard Thunderbird 5 by the Hood's missile) and in turn they head for London with her.
* MasterOfDisguise: When she is disguised as Wanda Lamour, even Parker doesn't recognise her.
* NiceGirl: One of the nicest secret agents you could ask for.
* NonIdleRich: Like Jeff, she poses as a RichIdiotWithNoDayJob, but goes on plenty of adventures.
* NotSoStoic: Stays calm in the face of danger. ''Loses it'' in the presence of [[EekAMouse mice]].
* PrettyInMink: Has a full-length mink coat.
* {{Troll}}: In ''Vault of Death'' she deliberately drives FAB-1 in a manner that scares the hell out of Parker. (Granted the latter was up to something.)
%%* StiffUpperLip
%%* {{Socialite}}
* SpotOfTea: Even her icon on Scott's Mobile Command Center is a teapot.
* UnlimitedWardrobe: Now we have a justification in "Alias Mr. Hackenbacker."

!Aloysius "Nosey" Parker
Voiced by: David Graham (original), Juan José Hurtado (Latin American Spanish dub, series), Raúl de la Fuente (Latin American Spanish dub, movie); Played by: Ron Cook

Lady Penelope's Cockney BattleButler, Parker has quite the past as a burglar and serial bank robber. Lady Penelope saved him from a life of crime, leaving him utterly devoted to 'er Ladyship. His vast underworld connections sometimes come in handy.

* TheAtoner: He was a master thief and a criminal in his past.
* BattleButler: He drives Fab 1, a pink future Rolls-Royce that will shoot you off the road.
* ButtMonkey: He's occasionally a victim of slapstick, most notably in "[[Recap/ThunderbirdsS1E25TheChamCham The Cham-Cham]]".
* CatchPhrase: Yes, m'lady.
* CoolOldGuy: Despite his past, he is a faithful butler and a loyal agent of International Rescue. Not to mention the times where his vast underworld connections prove beneficial.
* ADayInTheLimelight: "[[Recap/ThunderbirdsS1E13VaultOfDeath Vault Of Death]]", which details his past as a safecracker.
* ExpansionPackPast: He was a master thief before joining International Rescue.
* GagNose: He's among the most caricatured puppets in the show. Presumably, his schnoz earned him his nickname.
* ImprobableAimingSkills: Try counting the number of times Penelope compliments his shooting.
* LovableRogue: Penelope is certainly charmed by his criminal past.
* NiceGuy: Putting aside his past, he's generally good natured.
* PunchClockHero: A few episodes establish that Parker's days as a burglar aren't ''quite'' behind him. Arguably the most prominent example is in "[[Recap/ThunderbirdsS1E13VaultOfDeath Vault Of Death]]". Upon hearing there was an problem at the bank, he believes it to be a robbery conducted by an old cellmate (when Parker was convict) nicknamed Light Fingered Fred. Parker is unwilling to foil the plans of whom he considers an old friend and attempts to divert Penelope and Lord Silton away from the bank. [[spoiler: The actual emergency was that a member of staff, Lambert, was trapped in the vault with the air was being pumped out and the bank needed the one key that could open the vault. Even though he didn't know it, Parker's diversions could very nearly have cost Lambert his life.]]
* TheRat: Still has many connections with the underworld that come in handy.
* SatelliteCharacter: His character revolves entirely around Her Ladyship. He rarely has interactions with anyone else.
* YesMan: To Lady Penelope. ''Yes, m'lady'' is his CatchPhrase, after all.

[[folder: The Hood]]
Voiced by: Ray Barrett (series and ''Thunderbirds Are Go''), Gary Files (''Thunderbird 6'') , Gabriel Pingarrón (Latin American Spanish dub, movie); Played by Creator/BenKingsley

A mysterious terrorist with PsychicPowers and a penchant for masquerade who lives in a palace, deep in the jungles of Southeast Asia. He violently opposes International Rescue and will put everyone and everything in danger to steal their secret technologies. He often works alone, but has been known to sell his services to even greater and more mysterious powers.

* AdaptationalBadass: The 2004 movie not only amped up his PsychicPowers, but also had him succeed in his goal to steal the Thunderbird craft, ''and'' he nearly dropped Alan into The Mole's spinning drill turbines. (Bonus points for IR actually being aware of his existence too.)
* AllThereInTheManual: "The Hood" is never mentioned as a name or alias for this character in-series. The only aliases he goes by in-series are "Mr. Stutt", "Agent 7-9" and "Black Phantom".
* BaldOfEvil: He's the only bald character ever to appear in the series.
* BigBad: Except when a BiggerBad hires him.
* BigOlEyebrows: His frowner head in particular has huge, bushy eyebrows.
* CardCarryingVillain: From his appearance to his accent, from his villainous lair to his clothing. He seems to make an effort to look s evil as possible.
* TheChessmaster: He manipulates people using disguises, hypnosis and sabotage, mostly for the purpose of bringing out International Rescue.
* EvilGloating: Although usually with no audience.
* EvilIsPetty: Nothing is beneath him, including endangering children to get to his enemies or smashing a mechanical camera-mouse because it took the wrong pictures.
* FauxAffablyEvil: Often when he's in disguise, such as in "[[Recap/ThunderbirdsS1E14TheMightyAtom The Mighty Atom]]".
* GiantHandsOfDoom: His puppet was given much bigger hands than any other, in order to make him look more powerful.
* GlowingEyesOfDoom: His eyes glow yellow when he uses his psionic powers. (The 2004 movie has them glowing red instead.)
* {{Greed}}: The very first words in the series, as spoken by him:
-->"International Rescue... If only I knew their secrets, I would be the wealthiest man in the world!"
* TheHeavy: He is most certainly this in all episodes he's in.
* LargeHam: On his own he is very dramatic.
* LatexPerfection: Disguises himself perfectly, using rubber masks. To his credit, it must be a lot easier to pass off as a convincing ''puppet'' than as a human this way.
* LaughablyEvil: His moments of pure evil are offset with moments of comic relief. Although he is known to terrify children, his scenery chewing and ButtMonkey antics make him less scary.
* {{Leitmotif}}: He has his own sinister sounding theme music.
* MasterOfDisguise: He can disguise himself perfectly, another reason why he is called "The Hood".
* MrExposition: By way of his constant monologuing to himself.
* NoNameGiven: He's never addressed by any name in the series, not even "The Hood" (that's AllThereInTheManual).
* OutOfFocus: His appearances became fewer as the series progressed, to the point of him being absent altogether in the second season. He does show up in both movies, but his role in ''Thunderbird 6'' is little more than a cameo.
* PsychicLink: To Kyrano, who he uses to gain information.
* PsychoForHire: He's occasionally hired by some wealthy EvilOverlord.
* RedScare: Defied trope. With the UsefulNotes/ColdWar going on, the Andersons deliberately avoided making the main villain Russian, giving him an Oriental flavour instead.
* SmugSnake: One damn smug and snooty villain, who rarely goes beyond UnknownRival with the heroes and often uses his kindly and meek brother for his own purposes.
* ThinkingOutLoud: ''Constantly''. This guy just ''won't'' shut up to himself. He peppers it up with [[EvilLaugh Evil Laughter]] and the occasional IncrediblyLamePun.
* UnknownRival: Most of the The Hood's schemes revolve around stealing all of International Rescue's secrets and selling them to the highest bidder. Conversely, International Rescue is barely aware of his existence, apart from a vague notion that they have "enemies". Though "[[Recap/ThunderbirdsS1E24MartianInvasion Martian Invasion]]" brings the latter up for debate:
-->'''Virgil''': You know Scott, I've been wondering whether that "Stud" could be the agent that's been after our plans ever since we went into the rescue business.
-->'''Scott''': Yeah, I was wondering the same thing myself Virgil. Anyway, whatever disguise he wears...we'll get him. One day.
** And if the tie-in comic books are canon, this trope is definitely averted since in said comics The Hood directly confronts International Rescue multiple times.
** Also averted in the 2004 movie, which has him telling the Tracys (trapped on Thunderbird 5) that he is The Hood- though he says it so casually it almost sounds like he came up with it on the spot- and he is quite visible.
** Subverted in one episode where his submarine gets into a direct shootout with Gordon in Thunderbird 4. Gordon wins and sinks the Hood's ship, although he doesn't realize who the Hood is.
* VileVillainSaccharineShow: Played with: In a generally light and optimistic show aimed at full families, he habitually causes disasters that could potentially kill hundreds or thousands of people should International Rescue fail, just to give himself opportunities for industrial espionage.
* VillainsActHeroesReact: Justified - International Rescue's whole concept is reacting to disasters, and he causes them so that he can be on the scene already to spy on them.
* WouldHurtAChild: In Cry Wolf, he endangers children by luring them into a mine and causing its collapse.
