Bernice Summerfield hails from the 26th century, established in the Whoniverse as a Space Opera setting. She was companion to the Seventh and (briefly) Eighth Doctors before spinning off into her own continuity. Best friends with Ace when they travel together. Started out in the Virgin New Adventures novels and got her own Big Finish audio spinoff (among many, many other things).
Bi the Way: Though, to be fair, they were all under the influence of a sex drive stimulating pollen so it's unsure if she's into women the rest of the time.
Big Damn Kiss: Can't resist tackle-snogging the Eighth Doctor, following by a Sexy Discretion Shot. (The author was quite miffed that the BBC wouldn't allow an illustration.)
In "The Shadow Of The Scourge", a Big Finish episode written after that novel was published, Bernice sees a mirage of Eight while she's stuck in Seven's mind. She fancies him right away and jokingly asks Seven if he plans to regenerate soon. Seven teases her mercilessly about it for the rest of the episode.
Determinator: And how. When she was young, she went on an expedition all by herself, found nothing but a high cliff, promptly fell off it, and broke both her legs. She spent a month crawling back to base camp using only her arms. All the time keeping her wounds open so she could attract predators with the scent of her blood and feed on them. Bernice Summerfield does not give up.
Ethical Slut: Being from a time that's bordering on Free-Love Future, she's very open about sex and enjoys having a good shag now and again with the people she meets on her adventures. She also has no real nudity taboo, but always respects the fact that other cultures do. She still experiences jealousy, though, and values monogamy in her own long-term relationships. Benny and Jason have a tacit understanding about infidelity under extraordinary circumstances.
Fan of the Past: Benny is an expert on, among other things, 20th century Earth.
Mama Bear: Towards Peter. Her pregnancy was a complete surprise, considering her body was stolen by someone who then proceeded to have sex with Adrian (who'd fancied Benny since forever and didn't know it wasn't her). Benny takes it all in her stride as best as she can, although occasionally (like in "The Plague Herds Of Excelis") she has to take a break and get away from it all.
Mystical Pregnancy: The circumstances of Peter's conception were strange enough (Benny's body was possessed)—but, while pregnant, Benny then gets held prisoner by evil cultists who want her baby.
Bad Ass: As of Legion. It helps when you're stronger than all but the most fiendishly augmented humans (see below). Doubles as Badass Gay too.
Break the Cutie: Let's see, he was born by a C-section while Benny was in a prison and without much medication not a promising start. Then, during the occupation of the Collection by The Fifth Axis he was forcibly separated from his mother and hidden away for months. Then, when he was eight he was manipulated/hypnotised into murdering Jason by Braxiatel (and it's implied, later remembered every second of it) and was held responsible for the death. Two stories later, he was forced to go on the run with his mother (who regularly faces danger, so one has to question the introduction of a child into all of it). Of course, the biggest blow was when he was held on a slave planet for possibly three years with no knowledge of how he had arrived there or where his family were. And just before he was rescued by Alternate Braxiatel, his lover, Antonio, who'd been his only source of hope in all that time was murdered. It's hard not to blame him for being a little bitter by Legion. But just to rub in further numerous manipulations by his 'other' mother, AvrilFenman meant that a fragment of Antonio's mind (namely his love for Peter) continued to exist inside his own mind, convincing him that Antonio was still alive. So when it was revealed that Antonio was dead and that Fenman was using a solid light image of his body to make herself corporeal, Peter essentially had to destroy the image of the person he loved and it still contained a fraction of Antonio's consciousness, which was begging for death. All this by the time he was eighteen. In short; if you're a Big Finish character, don't have children, they will go through hell.
Soap Opera Rapid Aging Syndrome: Thoroughly averted. The character remained a baby/toddler for years after his birth (written in 2001) was only able to speak coherently five years of books and audios later. It wasn't until the 2010 releases that he became a teenager. Sort of played straight later when he was separated from Benny for four years (only two as far as listeners were concerned) and by the time they met up again he was eighteen years old, angry at Benny for abandoning him and had a boyfriend called Antonio.
Suddenly Sexuality: Although it makes sense considering his age and how being half-human is more of an issue for most people (although Antonio thought it made him look cute) rather than who they're interested in. Benny Lampshaded it.
There's a turn up for the books. Adrian Wall, wherever you are, I salute you! I wonder what you'd make of our grown up little boy.
Super Strength: Peter is stronger than all but the most augmented humans by late childhood. This was why Braxiatel manipulated/hypnotised him into killing Jason when he was eight years old. It also came in handy when he became the security officer on the complete cesspit of a planet that was Legion.
Another Time Lord, strongly implied to be the Doctor's brother. (Rumor has it that this was confirmed by the writers at a con, in fact.) He has an archive/museum/gallery of everything, which he keeps on a private planet. Used to be a neutral Mr. Exposition who'd send Bernice Summerfield off on adventures, but has been steadily getting more and more evil. First mentioned (sort of) in a throwaway line in the 1979 serial "City of Death". Currently also a main cast member in the GallifreyBig Finish audios.
Canon Immigrant: Yep, from the Epoch Boxset and onwards this series's Braxiatel has been replaced by the one from the Galifrey series. still uncertain as to weather this is an alternate universe, alternate timeline or something else at work.
Future Me Scares Me (Apparently, his future self scares him a lot. So much that he suspects himself of engineering the events of Life During Wartime, so he tries a little murder-suicide to destroy himself in a temporal paradox. We also learn that Braxiatel is so scared of his future self that he is keeping his Watcher (the inchoate form of his future self) locked up in the Collection to stop it from taking over him. Turns out Brax was right to be afraid of the person he might become.)
Timey-Wimey Ball: The Gallifrey audios feature Braxiatel as a member of the High Council, prior to his leaving Gallifrey, but also feature President Romana. Romana becomes President at some point after her return to Gallifrey in Blood Harvest, which is two novels afterTheatre of War, which introduces Irving Braxiatel, eccentric collector.

Temporally-displaced former teenage runaway from the 1990's and intermittent street hustler. Briefly and acrimoniously married to Bernice Summerfield, although all installments after their divorce make a point of showing that Aww, Look! They Really Do Love Each Other.
Insistent Terminology: A running joke; people never quite call him what he wants them to call him. He spent World War I as "Captain Kane", despite continuously insisting people just call him Jason, because it made him sound like a Marvel character.
Adrian is a Killoran: a seven-foot-tall alien that looks like a wolf/ape hybrid. He's head of construction at the Braxiatel Collection.
Abhorrent Admirer: Despite later confessing to having a strong platonic love for him, Benny viewed him in this way for a while after Peter's conception. Although Bev certainly sees something in him and even Benny seemed to be considering taking advantage of him shortly after Jason died (although understandably she was highly stressed).
Badass Baritone: Actor Harry Myers has a very low and gravelly voice, presumably to suit the character's canine influences.
Perhaps, Adrian just has a lower than average voice for a Kiloran? (He is larger and stronger than average remember) and also, it's clear from other plays that that voice is all Myers's, no sound effects
Berserk Button: Do not threaten or harm Benny or Peter or Bev or you'll have an incredibly strong humanoid canine bearing down on you.
Break the Cutie: Aside from the obvious of having no choice in loving a woman who he knows will never love him back; later he undergoes being locked up and enslaved by a bunch of fascists and then he is severely tortured by Doggles on Braxiatel's orders leaving him permanently scarred and limping.
Cannot Spit It Out: spends a great deal of the beginning of The Judas Gift working up the courage to propose to Bev. At the end, she reveals that she already knew
Interspecies Romance: One-sided with Benny when he ends up fathering her child while she's possessed by a soul sucker. Has another one with Bev Tarrant. They almost get engaged.
Informed Flaw: Kilorans are apparently aggressive, yet, while Adrian loses it on a few occasions it's generally on occasions such as Peter being kidnapped, Bev seemingly dying or while being tortured by Doggles during which, anyone would tetchy. The rest of the time he comes across as the most straightforward and agreeable character there is (but bear in mind he is surrounded my enigmatic Time Lords, ex-cat burglars and world-weary archaeologists).
Nice Guy: As mentioned previously, he is incredibly compassionate and caring of Benny and Peter, actually seems to respect Benny's preference for Jason (even though Jason could be a bit of a jerk to him sometimes). He genuinely loves Bev and she thinks that he's the best thing that ever happened to her. Unlike the other characters he doesn't suffer from a Dark And Troubed Past and doesn't have some hidden agenda. On the other hand, try to harm his loved ones and you find out just how strong a Kiloran is.
I'm guessing it says a lot about the nature of a series where your most easily relatable character is essentially an intelligent bipedal dog.
Punny Name: He thought 'Hadrian's Wall' was a real Earth name. To make it worse, he's a builder.
The Stoic: He was able to withstand the efforts of both the Fifth Axis and Braxiatel in their attempts to enslave or torture him for information.
And bear in mind that his species's tendency to imprint on their partners means that for years he had an uncontrollable desire for Benny which she would never return. Now consider how very very strong he is and how aggressive his species is; it's a wonder he was able to stop himself from forcing himself on her.
Super Strength: His son was able to tear a man apart when he was eight and he was only half Kiloran. Imagine what the full specimen is like.
Vitriolic Best Buds: with Jason after he conceded that Benny hadn't chosen him. Although they don't show it. It's notable that Adrian was the only one with a kind word to say at Jason's funeral.

Originally a one-off character from the Seventh Doctor audio "The Genocide Machine", Bev came back again... and again... and again. She was a member of an illegal salvage team, eventually met the Master, hung out with Seven and Ace for a bit, and crossed in and out of Bernice Summerfield's stories with great frequency.
In-Joke: She first appeared in the Big Finish "Dalek Empire" arc (before it became a proper spinoff), and was named on the basis that a Terry Nation-pastiche story had to have a character with a one-syllable first name and the surname Tarrant. (cf Jill Tarrant in "Death to the Daleks", Cal Tarrant in the Dalek Annual, Dev and Del Tarrant in Blake's 7, etc.)
