Sarah Jane Smith
Played by: Yasmin Paige (2007-08)New girl to the area, sees Sarah Jane communicating with an alien and after helping foil an alien scheme she joins Sarah Jane in her adventures.
- Kid Sidekick: All of Sarah Jane's teen companions qualify, but Maria is the one who works most closely with her.
- Like A Daughter To Me: To Sarah Jane.
- Little Miss Badass: Shows shades of this after leaving for America. In an email she says she's helping aliens hide from the United States government.
- Put on a Bus: In The Last Sontaran. She gets one more episode, The Mark of the Berserker, and then the occasional mention in emails.
So, there you go. The boy that was made by aliens to destroy the world? Saves the world YET AGAIN!
Played by: Tommy KnightThe boy Sarah Jane adopts in the first episode. He was grown in a lab by aliens, so he knows nothing about socializing at all. Very intelligent, but seems simple.
- Artificial Human: He was grown by the Bane, has a body that rejuvenates itself with little upkeep necessary, and isn't affected by some things natural humans are susceptible to.
- Belly Buttonless: He lacks a navel, due to being created by the Bane rather than born like a normal human.
- Commuting on a Bus: Luke left for Oxford after The Nightmare Man but appeared in several episodes afterward.
- Happily Adopted: Sarah Jane takes in Luke as her first adopted child and gives him his name, since it would be hard to find a better place for an alien-grown human teenager to grow up than her home.
- Momma's Boy: Not portrayed as a bad thing at all.
- Nice Guy: Very quickly becomes this. Then again, having Sarah Jane as a mother figure does and can transform you into this and Luke is definitely raised right and quite obviously follows her example to heart
- No Social Skills: At first.
- Photographic Memory: Luke rarely forgets any detail he learns, even before he was activated
- Portmanteau Couple Name: "Clani" in ''The Man Who Never Was.
- Socially-Awkward Hero: Much more so in season 1, when he's still getting used to human norms.
- Younger Than They Look: Was effectively "born" in the middle of the first episode, yet appears 14. As of Secrets of the Stars, this no longer applies, as he now considers himself to be born in 1994 rather than 2008.
Let's have a High School Musical moment! A group hug will sort everything out.
Played by: Daniel AnthonyCool kid, or at least likes to think of himself as such. Starts of as a bit of a jerk but slowly softens. Smarter than he'd like to admit.
- Beware the Silly Ones: Clyde may joke around and act "cool," but he's a member of Sarah Jane's gang, with the smarts and skills to show for it.
- Butt-Monkey: He gets slimed more frequently than anyone else, even Tempting Fate and suffering for it. And in The Curse of Clyde Langer, his bad luck gets Played for Drama.
- Casanova Wannabe: Kid-friendly version, of course.
- Deadpan Snarker: A wisecracker and a major fan of Puns.
- Disappeared Dad: His father left his mother during Clyde's childhood, but one day came back for him out of the blue. It did not go so well. It got worse when an alien artefact made him very possessive of Clyde.
- Hidden Depths: Clyde's a talented artist, and is in general much kinder and smarter than he sometimes appears.
- Parental Abandonment: We don't get to meet Clyde's family till series two (The Mark of the Berseker), though it is established early on that he lives with his mother after his father ran off with his mother's sister.
- Pungeon Master: This sometimes grates on the others' nerves.
- Second Episode Substitute: For Kelsey Hooper.
- Shout-Out: His name, to the British record producer and musician Clive Langer.
- UST: A mild case of this with Rani. He mentions a couple of times in "The Empty Planet" they may have to Adam and Eve the planet again, possibly seriously. They also kiss one another on the cheek a couple of times. This is also a literal case of UST, since the show got cancelled before their relationship could go anywhere romantic.
Played by: Anjli Mohindra (2008-2011)
Old Rani played by: Souad Faress (2009)Suspiciously Similar Substitute for Maria from series 2, another new girl and the daughter of the Park Vale Comprehensive School's new Sadist Teacher Headmaster. Wants to be a journalist.
- Beware the Nice Ones: Like the rest of Sarah Jane's gang, just because she's nice does not mean she's a pushover.
- Deadpan Snarker: Gets especially fed up with Clyde's shenanigans.
- Intrepid Reporter: In the making.
- Like Brother and Sister: With Luke.
- One Steve Limit: A recurring female Time Lord villain in Doctor Who was named the Rani. And that Slitheen posing as Rahnius (actor Ronnie Corbett) who makes a joke about there being "two Ranis" in From Raxacoricofallapatorius with Love.
- UST: Shades of this with Clyde pop up, especially when Luke mentions the idea of "Clani".
Voiced by: Alexander ArmstrongSarah Jane's alien computer, who is actually a sentient creature known as a Xylok.
- A.I. Is a Crapshoot: Averted. Even in The Lost Boy when he's "against" Sarah Jane, it's intentional on his part and he's actually playing both sides.
- Aliens Speaking English: Mr Smith is actually an alien hooked up to a computer, and used his access to the internet to learn English.
- The Chessmaster: He plays both sides very effectively in The Lost Boy.
- Good Feels Good: After his reprogramming, he begins to develop a sense of humour.
- Left the Background Music On: His fanfare, as revealed when he crosses over into Doctor Who.
- Magical Computer: He can do pretty much anything he needs to by virtue of being a Sufficiently Advanced Alien.
- Sealed Evil in a Can: The race of supercomputers that he belongs to. Averted post-reprogramming, as he is now genuinely on the side of Sarah Jane.
Played by: Sinead Michael (2011)
Baby Sky played by: Chloe Savage, Ella Savage, Amber Donaldson, Scarlet Donaldson (2011)Alien girl who joins the cast in Series 5. Left on Sarah Jane's doorstep as a baby and rapidly ages.
- Constantly Curious: she is constantly asking questions, due to only being a few weeks old
- Cousin Oliver: The addition of Sky in the fifth season threatened to be this, but ultimately ended up averting the trope because the character ending up not being annoying and she never really got to replace any cast member in the long term because the series ended only six episodes after she joined. Not her fault, either.
- Defusing the Tyke Bomb
- Happily Adopted: The second child adopted by Sarah Jane, mainly because Sky's real mother was an unsympathetic monster who bred a daughter merely to be a war weapon.
- Human Alien: downplayed after the first story of the fifth season, but this may be why she was unaffected by the curse on Clyde's name
- And, in the plan for 'Battle for Bannerman Road', she was going to be revealed to be part TRICKSTER.
- Plot-Relevant Age-Up: She is born as a Fleshkind baby, but when her mother activates her genetic programming, Sky rapidly ages into a pre-teen. Technically, she was added to the cast because the others were growing up and some were even Dawson Casting.
- Shock and Awe: The end of "Sky" suggests that her electric powers haven't totally gone away. In the final story, she mentions being sensitive to electrical vibrations.
- Suspiciously Similar Substitute: For Luke. She is a teenager with No Social Skills who is Younger Than They Look and is adopted by Sarah Jane, and was grown by a woman (really an alien) as a weapon, and said woman refers to herself as the real mother. This is heavily lampshaded in Series 5, episode 2 when Clyde says that having her around is like "deja vu" and Sarah Jane lets her wear Luke's old clothes.
- And again when they meet in Episode 5, Clyde calls Luke "[his] biggest success - Frankenbane, now a normal teenager", and they eventually form a Brother–Sister Team.
- The Pollyanna: Lampshaded, deconstructed, and invoked. Sky sees everything in the world as fresh and new with the innocence of the baby she once was, even remembering when she was a baby for that brief period before being aged up. She gets called out as a Pollyanna in The Man Who Never Was.
- Walking Techbane: when she's a baby her cries short out anything electrical. When she is aged up she has slightly more control, but Mr. Smith is still nervous around her.
- Wrench Wench: An entirely non-fanservice example in the audiobooks.

Played by Cyril Nri and a parrot (2010-2011)Two enigmatic self-styled "servants of the universe" who have occasionally press-ganged Sarah and friends into serving their probably benevolent purposes. Their origins and affiliations are unknown. The Shopkeeper appears to be an avuncular dark-skinned man in eccentric early-twentieth-century clothes, and the Captain to be a large red-and-yellow parrot.

After members of their family were killed by the Doctor, they built up a grudge against planet Earth.
- Exposed Extraterrestrials: When not in human suits.
- Fat Bastard: They kill fat humans and use the skins as disguises, because their body compressing technology only compresses them enough to fit. Except in The Lost Boy, where two of them use the skins of a rather skinny couple to pull off their plan, thanks to newer, more advanced compression technology.
- Hunting the Most Dangerous Game: They love killing humans.
- Palette Swap: The Slitheen-Blathereen from The Gift are brownish-orange, compared to the more yellow-green Slitheen.
- Also in The Nightmare Man, an unnamed Slitheen is shown to be a much darker shade of green than the others shown, leading some to believe that he is actually from another Raxacoricofallapatorian family.
- Toilet Humor: A major part of their character humor. But absolutely averted in The Lost Boy.
- Weaksauce Weakness: They explode upon contact with vinegar, because they're made of calcium.

The main recurring singular villain in the series, out to take down Sarah Jane, and later the Doctor himself.

- Big Bad: The main bad guy of the show, his goal is to alter the timeline and cause chaos, which he hopes to do by removing the Doctor from it.
