Characterisation Marches On: Their personalities in series 1 and 2 get increasingly changed and Flanderised in later series, although of the three Bill is the most unlike his personality in later series.
Nice Mean And In Between: Before flanderization, Tim is the kindest of the three Goodies and also a Kindhearted Simpleton. Bill is rude and insensitive and even has a Hair-Trigger Temper (mainly in Seasons 3-9. Graeme is a polite man, but he can often come across as snarky, snobbish and bitter.
Took a Level in Jerkass: In series 1 they are three friends who start The Goodies service as a way of helping people. However as the series goes on, all three of them become more likely to play Villain of the Week, they become much less friendly and more violent towards each other and are less motivated by helping people than by how much they can get paid for it.
Tim Brooke-Taylor
Berserk Button: Insulting the royal family or the UK is likely to get him going.
Butt-Monkey: Tim gets hurt and picked on much more than Bill and Graeme. (This was probably due to Tim being the only cast member who wasn't also writing the series.)
Camp Straight: Although the 'straight' part is debatable.
Characterisation Marches On: Starts the series slightly patriotic and highly-strung, but quickly becomes an effeminate, neurotic wreck obsessed with the royal family and patriotic in the extreme.
Character Tics: The aforementioned "I'm a teapot!" panicking, making patriotic speeches to "Land Of Hope And Glory" and bursting into tears.
Cross Dresser: Whenever the job of the week requires a woman, Tim will invariably be the one to drag it up.
Dirty Coward: Freaks out and tries to flee at the first sign of anything getting even slightly dangerous.
Flanderisation: From being slightly patriotic and easily upset to completely neurotic and obsessed with the royal family.
Goofy Print Underwear: Along with his Union jack waistcoat, Tim wears Union Jack boxers and socks.
Inelegant Blubbering: Has a habit of bursting into tears with little to no warning.
Large Ham: Particularly when he's panicking or performing one of his speeches.
Patriotic Fervor: His patriotism is played up in the later series, including him wearing his Union Jack waistcoat, obsessing about getting an OBE from the Queen, and making patriotic speeches to "Land Of Hope And Glory" in the background.
The Leader: In earlier series, when the trio were friendlier with each other and ran their service as a way to help people, he was this. Not so much in later series though.
Took a Level in Jerkass: Is The Leader for the earlier series, however becomes increasingly cowardly and unpleasant to the other two as the series goes on.
Upper-Class Twit: In demeanor if not in status, especially in the later seasons. Behind-the-scenes commentary traces this back to him having a hyphenated name.
Graeme Garden
Characterisation Marches On: In series 1, he's simply an eccentric boffin, however with each series starting from series 2 he becomes more and more of a Mad Scientist, and also becomes much more prone to villainy.
Comedic Sociopathy: Particularly in later series, as he starts displaying very little empathy for anyone or anything that isn't science.
Cargo Ship: In one episode, he goes on a date with, and nearly marries, his computer, and in another is mentioned to have been "put away for having an unnatural relationship" with it.
For the Evulz: In later series, if he's not just doing whatever mad scientist scheme he's working on that episode For Science!, he's doing it for this too.
Mad Scientist: Can end up like this on occasion, and in later seasons was the most likely character to play the Villain of the Week.
'70s Hair: Those sideburns, otherwise known as mutton chops. Averted in series 8 and 9, due to those series being made in The '80s, and Graeme has shaved his sideburns to fit, unlike the other two's hair, which remains pretty much the same.
Smart People Wear Glasses: In "The End", he's described as representing "the scientific and technical class" because he wears glasses.
Took a Level in Jerkass: In series 1 and 2 he's largely just an eccentric boffin, albeit one who lets it all go to his head a bit sometimes. From series 3 onwards he becomes more of a Mad Scientist and much more likely to be Villain of the Week.
His Ecky-Thump black pudding and huge flat cap in "Kung Fu Kapers".
Paper-Thin Disguise: "Robot" has him dressed up as a girl called "Helga". Despite him not shaving or changing his voice, everyone believes he is indeed Helga.
Pet the Dog: Even though he is often mean to Tim, Bill is always quick to reassure him when he gets upset, as seen in "The Baddies", where he comforts his crying friend.
Took a Level in Jerkass: In series 1 and 2 he's a vocal pacifist and pretty laid-back too, however he gets more and more violent and short-tempered from series 3 onwards.
