Doghead Thirteen

Calum Wallace, AKA "Doghead Thirteen" is the author of about a dozen Fanfics, including several delightfully deranged Harry Potter stories and a complex set of interlinking Mega Crossovers. Among other things, he is known for the very... different versions of Harry Potter who show up in his works.

His major projects are:
 * Enter the Dragon, a Harry Potter fanfic which would have eventually crossed over with Shadowrun. In it, Harry is turned into, well, a dragon by a freak accident at Stonehenge when he is eight. Unable to support his literally all-encompassing appetite (Dragon!Harry eats meat, every plant that grows, random potions ingredients, coal, pig iron and sheet steel, and drinks both water and petroleum products of all kinds), the Dursleys call upon Dumbledore, who moves Harry to the grounds of Hogwarts.  There he is raised (and studied) by the school staff, whom he comes to view as his family (yes, even Snape).  As he grows, he has interesting conversations with those who are aware of his presence there, decides what constitutes being a "proper" dragon, and sets about to live his life accordingly.  The story is currently abandoned at the point where Harry and Hermione are about to board the Hogwarts Express for the first time.  Wallace has indicated that the core "gimmick" of the story is hyperactive!dragon!Harry, and in the long term he would either have to move away from this characterization as Harry matures, losing what is arguably the story's main appeal, or leave Harry hyperactive and immature even as his classmates become adults.  Unable to resolve the dilemma, Wallace suspended work on the story and offered it to anyone who cared to try to complete it.  At least one author has begun an attempt.
 * The Book of Dobby Reboot: Per Arcana ad Astra, which is an AU diverging at the end of Harry's fourth year, eventually crossing over with Girl Genius. Kicked out of Hogwarts for political reasons, Harry intends to take the fight to Voldemort in a way that neither the Dark Lord nor the Ministry is equipped to understand. Dobby is organizing the house-elves into as close a replica as possible of the RAF circa 1940, and the Gringotts goblins are apparently the Jaegers. It's crack, but highly entertaining; also incomplete. It's a reboot/Retool of an earlier story, The Book of Dobby: Per Arcana ad Astra, which is different enough to be worth checking out as well.  This, too, has been abandoned, for less clear reasons than Enter the Dragon.
 * Top Dog, a really huge Mega Crossover universe patterned in form after Undocumented Features. The main continuities are Enter the Fnords, which is Harry Potter with a severely traumatized and Badass Anti-Hero Harry in a magical world upgraded to fit into Top Dog's intergalactic politics; Biker Half, which is Ranma ½ with Ranma the heir unaware of one of the strongest Amerai clans; and A Fox in Tokyo, which is Naruto with guns and Claymore mines, in a Konohagakure transplanted into the Nerima of Biker Half. Epic storyline, and a wonderful series of funny moments as you see the canon universes fitting into the crossover.
 * The Sea King, a crossover between Harry Potter and Deadliest Catch.
 * His current active project, not yet entirely available to the public, is The Scourge From the North, a cross between Harry Potter and an idea from Warhammer that's been lifted out of its original context and mutated dramatically, along with a bit of Girl Genius (again). Living in and around the Orkney Islands (and parts of Scandinavia) are the Orcs, a subgroup of magical humanity who are very large Viking-like folks, mostly not wand-users, who are very good at violence and have no aversion to using any Muggle technology that suits their needs (like machine guns and armored trucks).  And Harry Potter, who has recently been affianced to Pansy Parkinson as well as taken Hermione Granger as a concubine, is their uncrowned king.  They learn about him at the beginning of his fourth year, and vow that he will not be kept from his people and assassinated as his father -- another uncrowned king -- was.  By the time the Goblet of Fire spits out its (not entirely expected) choices, an army of Orcs several thousand strong is on its way to Hogwarts to protect their king and a fortified bunker is already being built in the Forbidden Forest as their advance scouts go to war with those centaurs who haven't decided to make a run for France.  Features an increasingly tech-savvy Harry who's turning the Chamber of Secrets into a high-tech supervillain lair with the help of a few house-elves, a different course for the Tri-Wizard Tournament, a civil war cleverly fomented among the Death Eaters, and both Pansy and Hermione in bondage.  Among other things.  Definitely NSFW, as of the end of 2017 it is up to four very large chapters that are only available through a specific Yahoo Group.


 * Alternate Universe Fic: Most of his fics, especially his large projects, are based in AUs of some variety.  Top Dog is built by welding AUs together into a single continuity.
 * Brains and Bondage: As seen in his depictions of Hermione.
 * Casual Kink: Light BDSM (playful spanking, mostly) shows up occasionally, usually between Harry Potter and Hermione Granger.  The Scourge From the North goes well beyond "light" without getting particularly Squicky.
 * Creator Thumbprint: In his Harry Potter fics, you will frequently see House-elves speaking hilariously over-mangled English (and who don't think anything like a human), Harry-Hermione shipping (sometimes with a touch of playful BDSM), and a Harry (or Hermione) who is mechanically inclined at a level anywhere from handyman-tinkerer to self-taught aerospace engineer.  (Or genuine Spark.)
 * Muggles Do It Better: The core idea behind Harry's plan in The Book of Dobby.
 * Mythology Gag: Doghead frequently locates Hogwarts about a dozen miles inland from the coastal Scottish town of Mallaig. The railway near Mallaig was used by the Harry Potter movies for a decade as the shooting location for the Hogwarts Express.
 * Shipping: Is very much a Harry-Hermione shipper in the Potter fandom.
