The Sixth Doctor's first comic stories were written before his first televised episode, and with no characterisation to go on, the writers interpreted him as a much kinder incarnation than the Jerk Ass we all know and love from the TV show. It stuck, and his adventures with Frobisher and Peri show him as a kind, determined intergalactic hero.
Alice Allusion: He features as the white rabbit in Peri's hallicunation sequence.
Early-Installment Weirdness: For the first story, the artist had no idea yet what the back of Six' coat looked like, and simply improvised.
Guile Hero: Having a companion who can shapeshift offers endless possibilities in this regard.
In addition to his developments in novels and audio adventures, the Eighth Doctor faced significant development in comic form as well.
Aborted Arc: He would have ended his story by regenerating into the Ninth Doctor, but the writers and Russell T Davies agreed that they couldn't find a way to make it work.
Although in the notes at the back of "The Cruel Sea" the writers say this was probably a good thing as it would have been de-canonized by the War Doctor.
Big Damn Kiss: Gets another very big damn one with Grace, leading Izzy to assume that he and Grace are boyfriend and girlfriend. (He never bothers to correct her.) Also gets snogged by Destrii a few times over, though against his will.
Changed My Jumper: Halfway through his adventures, the Eighth Doctor wears a long, dark blue coat rather than the dark green one he wears in the TV movie. Author Scott Gray felt that the green coat didn't work well once the comic started being published in colour. For a winter adventure in the wild west, he adds some warmer clothes and a hat he got from Mark Twain; for a Victorian story, he wears his usual gear and a nice top hat. (In ancient Egypt, he just strips down to nothing but a pair of shorts for the entire story.)
A God Am I: Merging with part of the space/time vortex itself. He's very moved by the experience and ready to say goodbye to physical life forever, but seeing that Destrii needs him snaps him out of it again.
Heroic Suicide: He offers the Cybermen to let them kill him, so they can copy his regenerative pattern and hopefully leave the humans of earth alone as a result. They (of course) betray him and he (naturally) had already escaped by that time.
Hot Blooded Sideburns: Starts off with a nice pair. Izzy later happily mocks him for it when they look back on their past selves.
Nice Hat: He spent a full year of comics travelling alone, and would start off each story with a different hat instead of a companion. Including a fez.
Roaring Rampage of Revenge: His graphic, horrifying genocide of an entire fleet of Cybermen, delivered with all the passion and rage of an angry God. (Which he is, pretty much, at the time.)
Torture Porn: It's the Eighth Doctor. Of course there's Torture Porn. His final adventure sees him badly beaten up by the Cybercontroller.
Sharon (Fourth Doctor)
The first original companion to be created for Doctor Who Magazine. Sharon was a clever and fairly stoic teenager from Blackcastle, who got mixed up in an adventure involving the Meep. Rather than calling the police, she much preferred to sort things out by herself. First non-white companion in any medium.
Brainwashed: In her first story. In the same story it also later leads into...
Plot-Relevant Age-Up: She starts out as a secondary school student, but due to a fault in the TARDIS's chrono-compensator in one of her later stories, it made everyone in the TARDIS age four years whilst they were passing through a time rift.
Token Minority: With a side helping of Political Correctness Gone Mad. Sharon was a black girl from Blackcastle who got sucked into a black hole, where she was hit by the black light radiation from the Black Sun and everyone got turned into zombies by the Black Star Drive. Trivia: The Doctor refers to the Black Guardian in the story.
A shapeshifter who prefers to take the form of a penguin. Has a daytime job as a private eye. Appears outside of Doctor Who Magazine in the "Prisoners Of Time" IDW comic miniseries, in the novel "Mission: Impractical", and in Colin Baker's Marvel graphic novel "The Age Of Chaos". Also appears in the Big Finish Doctor Who audios, where he's voiced by Robert Jezek. Not to be confused with the character from Torchwood: Children of Earth.
The Bartender: Sometime after parting ways with the Doctor, Frobisher retires from adventure and settles into this role at his bar, "Bish's."
Belated Happy Ending: Fifteen years after his last comics appearance, Frobisher returned to the stories, now the owner of a successful bar and happily dating a nice woman.
Breakout Character: Originally a comic book creation, Frobisher has had multiple feature length appearances in both Big Finish Audios and the novels. He also appears in the IDW and Marvel comics, and he's the first character to be mentioned in Doctor Who Legacy without ever having been referenced in the TV series.
The Lancer: His ego and arrogance are ever so slightly larger than that of the Doctor, which is no small feat given that this is Six we're talking about. This was specifically used in the Big Finish episode "The Holy Terror", as Rob Shearman felt Frobisher could meddle with the planet's culture in ways the Doctor would never even consider.
No Name Given: He's said to have taken many aliases before going with Frobisher, which he sticks with thereafter. His original name is never disclosed.
Shapeshifter Mode Lock: Frobisher got stuck in penguin form in his second adventure for "personal reasons", since the writer considered him overpowered. The next writer blatantly ignored that, and from that point on, his powers came and went Depending on the Writer. It was eventually explained as chronic monomorphia, which sometimes even conveniently came over him right in the middle of a story's climax. Even when he's not afflicted by it, though, he prefers the shape of a penguin.
Sizeshifter: He can shrink enough to hide comfortably within a phone receiver and grow to a much taller form than the Doctor's.
Voices Are Mental: Notably averted. Frobisher at one point spends almost an entire Big Finish episode shapeshifted into the Sixth Doctor. Including his voice. This leads to Colin Baker impersonating Robert Jezek playing Frobisher pretending to be the Doctor. It is completely glorious.
A happy young "fan-geekoid" from Stockbridge, who's working as an UFO hunter together with Maxwell. Joins the Eighth Doctor on his travels, and in the process comes to terms with the reality of all of time and space, with having been adopted, and with being gay. Also appeared in a Big Finish Doctor Who audio, voiced by Jemima Rooper.
Action Girl: Very much so after the body swap, as she has no qualms going hand to hand with a demonic super strong energy creatue. Was never one to avoid danger before, though she was more of a Plucky Girl to begin with.
Adrenaline Makeover: Started off as a shy Geek who used travelling with the Doctor as a way of dodging her adoption issues, with kind of androgynous, frumpy features and clothing. Later morphed into a confident Amazonian Action Girl (whether a fish or a mammal) who had no qualms punching monsters.
Changeling Fantasy: Subverted. Due to being adopted, Izzy fantasises about having special parents, about actually being an alien princess and how she'll one day be picked up and brought back to her home planet. Since this is Doctor Who, "Be Careful What You Wish For" is in full effect, and her fantasies come completely true... when she's trapped in Destrii's body. And Destrii's home planet turns out to be a complete hellhole, where being a princess is just about the worst job imaginable. She eventually realises how much she cares about her adoptive parents and goes home to them. Her real parents' identities are never revealed.
Epiphany Therapy: Seeing into Destrii's mind makes her realise that her own problems are completely trivial in comparison, which in turns leads her to admit to herself that she's gay and that she's been awful to her parents for years.
Hollywood Nerd: She loves to use sci-fi pop culture references. Granted, there are some pretty obscure ones in there as well.
How Do I Shot Web?: Destrii's body is amphibian, and once Izzy gets stuck in it, she has to learn how to breathe water. Problem is, she can't even swim. The Doctor and the TARDIS manage to get her into the swimming pool just in time before she dries out, and Eight has to forcefully "baptise" her. It's fairly traumatic for poor Izzy.
Gayngst: Quite a bit of it, and also the reason she's so upset having having been adopted. Her parents are the sweetest couple you could possibly imagine, but Izzy represses her sexuality to the point where she starts lashing out at them over entirely unrelated matters — including the fact that they're not her biological parents. She gets over it in the end.
Get a Hold of Yourself, Man!!: In a moment of self pity she wangsts to real life artist Frida Kahlo about the loss of her old body, telling her she has no chance of understanding what she's going through. However, having been the victim of crippling physical injuries herself, Frida angrily tells her that despite the trauma she didn't let her experiences break her and that she's not the only person to suffer such a trauma.
Pop Cultured Badass: Fits the trope to a T. At one point, a villain in 17th century Japan tries to conquer the land using images of the future ripped from Izzy's brain; fortunately, Izzy's knowledge of Japan consists of Sentai shows, impressive amounts of 90's anime, and Godzilla, which promptly and thoroughly ruins the villain's plans.
Straight Gay: Although allusions to Izzy's homosexuality are made throughout the strip, it's never unambiguously confirmed until her final story.
Took A Level In Bad Ass: Being turned into a super strong, lightning fast human fish hybrid probably had something to do with it.
Fey Truscott-Sade (Eighth Doctor)
A kind of on- and off-again companion to the Eighth Doctor, whom he had allied with previously. A secret agent for the British Crown in the 1930s and 40s. Fey's a thoroughly Badass Action Girl — she punches Time Lords in the face.
A friendly, silly, heroic adventurer who happened to have been Cyberconverted somewhere along the line. He spontaneously regained the capacity to experience emotion, but not his memories of his previous life. Originally introduced in solo back-up strips in the eighties, in which he wandered the universe trying to do good despite everybody's terror of him. Later reintroduced during the Eighth Doctor comics, much older and more experienced, in which he became a full-scale companion and a major player in one of the comics' arcs. (No connection to the tellurium-themed bad guys.)
Ascended Extra: Only had a handful of brief appearances in Doctor Who Weekly and was then absent from the comic strip for quite a while, before becoming the Doctor's new companion.
A God Am I: He eventually becomes the keeper of the axis of all multiverses.
Guardian of the Multiverse: Becomes Guardian of the Omniverse. That's right, not just all possible worlds of the Doctor Who universe, but of all universes and multiverses and worlds of fiction out there.
Quest for Identity: Initially subverted, because the idea of regaining his memories is too painful. Izzy forces him, eventually.
Same Character, But Different: Writer/artist Adrian Salmon didn't even intend to bring him back, he was just toying around with an old character for an elaborate pencil test. Because of this, he felt free to let his interpretation of Kroton be inspired by Blaxploitation tropes and Luke Cage: Hero for Hire in particular. Salmon showed the pages to his friends working at Doctor Who Magazine, promptly got hired to expand the pages into a full-length comic, and became a mainstay artist for the franchise. (Kroton's newfound silliness was simply explained by him being a few centuries older than the last time we saw him, and more experienced with life.)
The Eighth Doctor's final Doctor Who Magazine companion, an alien who escaped her hellhole homeworld to see the universe. She turns out to be very mentally unstable and has a whole lot to learn about morality. Got hit by an Aborted Arc, courtesy of the TV series's return.
Abusive Parents: Tortured by her mother from a very young age, both physically and emotionally.
A God Am I: Her brief stint merged with the Horde.
Aliens Steal Cable: How she became a fangirl — her uncle Jodafra fed her a steady diet of Star Trek, The Avengers and old Westerns, to get her excited about exploring other worlds. All for his own purposes, of course.
Amazonian Beauty: Tall, gorgeous and dressed in only the bare necessities. She subjects Izzy's body to a serious exercise regime as well.
Amazon Chaser: Some of the soldiers in "Bad Blood" seem rather allured by her combat skills.
Anti-Hero: Type V. Gets better as time goes by, roughly a Type III by her final appearence. The Doctor offers her a chance to better herself, and she chooses to accept.
Anything That Moves: Has a habit of calling people "Sweetie" and blatantly flirting with them. She really wants to shag the Doctor, but he's having none of it.
Axe Crazy: Trained as an arena warrior, and trained to fight dirty, ever since she could walk. She loves carnage, and even after her Heel-Face Turn, she revels in the bloodshed.
Body Snatcher: Destrii tricks the Doctor's companion Izzy into swapping bodies with her to avoid capture by her people. It gets reversed. She later acquires a hologram pendant from a group of enemies, which allows her to project herself as a human.
Character Development: Gets a nice amount of it, and would have gotten more had her stories not been cut short.
Easily Forgiven: She forcefully kisses and sexually intimidates the Eighth Doctor a few times over, and he's not remotely happy about it. He still takes her on as a companion, after she's nearly beaten to death by Jodafra and shows the beginnings of a Heel-Face Turn. He makes sure to let her know she's "on probation" and has a lot to make up for if she really wants to travel with him.
Even Evil Has Standards: Her final and very ugly break with her uncle Jodafra comes when she discovers that he's planning to feed a bunch of little kids to a monster in exchange for power — hurting children hits rather too close to home for her.
Hollywood Nerd: Together with Izzy, one of two the Doctor knew at the same time. (The narrative uses this thematically.) Destrii fangirls 1960s and 70s sci-fi and westerns. She and Izzy initially bond over Star Trek quotes.
Innocent Bigot: Her inexperience with Earth minorities coupled with her over-exposure to twentieth-century Western pop culture leads her to tease an Asian cook, Tony, on his resemblance to Chinese stereotype Hop Sing from Bonanza. Due to exposure to the Cybermen's emotion aggravation device he tries to kill her, leaving a baffled Destrii to wonder why he hates Bonanza so much. The two spend the rest of the day facing Cybermen together, and Destrii comes to understand that she made a bit of a mistake.
Self-Made Orphan: Kills her mother. After looking at Destrii's childhood, you can see why.
Token Evil Teammate: When Eight takes her on as a companion, she's only just starting to realise that there are other ways to live.
Totally Radical: Late 1990's-early 2000's variety, at least in her earlier appearances. Justified as she was raised on a selected batch of pop culture by her manipulative uncle.
Wild Card: Due to being extraordinarily mentally unstable.
Majenta Pryce (Tenth Doctor)
When they were told that the 2009 Doctor Who TV specials would not feature any ongoing regular companion, the strip's creators decided to revive the DWM tradition of original companions for Ten's final arc. Originally introduced as a minor villain, "Madge" later joined up with the Doctor against his will, since she blames him for her amnesia and expects a cure.
Affably Evil (to an extent; she's more ruthless than evil, but she's terribly polite about it)
The local nerd in the English country village of Stockbridge, the DWM comics' standard location for when something's weird going down in a bucolic setting. Has repeatedly turned down the idea of travelling with the Doctor because he claims to be too cowardly, although he's shown significant courage when pushed. Introduced Izzy to the Doctor and has some mild, vague psychic abilities. Has also appeared in one Big Finish Doctor Who story, "The Eternal Summer", where he was voiced by Mark Williams.
A creation of the Matrix Lords of Gallifrey, those Time Lords whose minds survive in the Matrix, serving as their agent in the wider universe. A sometime ally of the Fifth and Eighth Doctors, who through his adventures with them discovers he's slowly developing free will. Appears in the Big Finish Doctor Who audios, where he's voiced by Mark Donovan.
Abnormal Ammo: His gun fires psychic bullets, powered by the will of his backers.
The Blank: Has a featureless black sphere for a head.
Abslom Daak was a thuggish Human criminal from the mid-26th century. Eventually he was convicted and given the choice between vaporisation or exile as a Dalek Killer. He chose the latter. During this, his only true love was killed by a Dalek survivor that Daak had overlooked, leaving Daak grief-stricken and vowing to exterminate every Dalek in the galaxy. Made his first appearance in a back-up comic strip in 1980. He met the Fourth and Seventh Doctors and also Bernice Summerfield a couple of times (he lived during the same 26th century time period as her).
Sociopathic Hero: Daak is almost psychotically eager for battle to the point that he's along with the Doctor the only being able to make Daleks feel fear (at least until River Song comes on the scene).
True Companions: The Star Tigers crew - the Draconian Prince Salander, Vol Mercurius and an Ice Warrior, Harma, who came to travel the galaxy with Daak in a small ship known as the Kill-Wagon.
An adorably cute alien fluffball who is actually a murderously psychotic Galactic Conqueror. Introduced in the Fourth Doctor comic story "The Star Beast", a parody of cute Alien Among Us narratives in which he crashed on contemporary Earth while fleeing justice and tried to pull a Wounded Gazelle Gambit. Made several later appearances as a comedy villain. Also appeared in one Big Finish Doctor Who drama, "The Ratings War", in which he was voiced by Toby Longworth.
The froglike CEO of Intra-Venus Inc. who wanted to possess the TARDIS, and regularly hired mercenaries to pursue the Fifth and Sixth Doctors. Also appeared in a Death's Head crossover, where he hired the titular Freelance Peacekeeping Agent (and definitely not a mercenary) to pursue the Seventh Doctor. Appeared in the Big Finish audio "The Maltese Penguin", voiced by Toby Longworth.
Aborted Arc: Despite being built up as a huge threat and potential long-term villain, he drops off the radar without explanation when the "Voyager" arc gets going.
This Master was one of the most coolly manipulative and patient versions seen so far, simultaneously juggling a grand plan to achieve divine power with a pettier plan to morally humiliate the Doctor and turn his favourite species into the kind of culture he's spent his life fighting. Was granted the body of an old, balding human vagrant, which he suspects was a kind of punishment.
Decoy Protagonist: It turns out that the conflict between him and the Doctor was just a sideshow, and the real Good and Evil contenders for the Cosmic Keystone were the Doctor's companion Kroton and the Master's chief minion Katsura Sato.
Race Lift: This version of the Master happens to be black in human ethnic terms, although little is made of it. This is due to his mind being placed in the body of a human vagrant.
Destrii's foppish, devious uncle and the only member of the family she actually likes. Looks like a humanised lion. When he's introduced, he seems sympathetically roguish, but later developments reveal just how evil he can be.
Aborted Arc: According to Word of God, he would have made future appearances as Destrii's Arch-Enemy had the Eight-Destrii comics not been cut off by the revival of the TV series.
