He also devised a method of transmitting information via parchment with absolute security... just seal the parchment and enchant it so that it requires a drop of the intended recipient's blood to be opened.
Crazy-Prepared: Just going by the number of weapons he's carrying at any given time, he's got to fit this trope.
He also broke one of Kalia's ribs with the butt of a broomstick in one of his first "onscreen" fight scenes.
Manipulative Bastard: After forcing Lena to stop bullying his friends at the point of a loaded fist, he decided she shouldn't stop bullying people entirely... he just redirected her negative energy toward the Slytherins, and then let her loose on them.
The Determinator: The reason he gets back up from all those injuries. Dates back to Hogwarts Rising, when the only purpose for the character's existence seemed to be Quidditch and he would keep playing no matter how badly hurt he got. This eventually earned him the nickname "Pinata", which was a Lampshade Hanging of his creator's screen name.
In the Blood: Considering he's probably just about the darkest hero ever, and considering his father was so bad that he murdered his mother in front of him, Jason's got a lot of potential to be a villain later on down the line.
Torture Technician: He's probably not the best torturer on the site, but he's in the top five. Maybe even in the top three.
Master of Disguise: It helps to have artificial body parts which can be swapped out for other artificial body parts that look different. If he has the same nose in two consecutive threads, I'd be really surprised.
Fan Nickname: Even though there's no canonical basis for it, everyone calls her "Maddie" when referring to her out of character.
Unequal Pairing: As Badass as Madeline is, Jason is about ten times more badass. Maybe justified, since he's the one who trained her.
Morality Pet: She does keep Jason in line, to at least a certain extent.
Distress Ball: Just because she's a Badass doesn't mean it's not ridiculously dangerous being Jason's wife. Someone's always after her, and although she can usually fight them off herself sometimes she needs Jason's help (other times, Jason just takes it upon himself to help).
Pet the Dog: Yes, he was a Jerkass for most of the time he was a teacher... but he showed he could be nice when he took Tawnie out of class and personally brought her to the hospital to see her dying mother. It was the site's first Crowning Moment of Heartwarming.
Gorn: He is not pleased with the other werewolves, and is currently the only character inflicting bloodier deaths than Jason.
Broken Ace: Former Ravenclaw and Auror, skilled fighter, expert on Transfiguration, Magical Creatures, psychology, history and culture, and always willing to put his own neck on the line for others. Shame he's also a paranoid, isolated workaholic with a serious dose of self-loathing. And a vampire.
Draco in Leather Pants: The whole reason the character was created. No, seriously... on the old Hogwarts Rising site, the extent of the description which could be given was "Draco Malfoy's girlfriend".
Omniglot: Her proficiency with languages makes her useful to the Department of International Magical Cooperation.
Jerkass: Just don't expect her to be sent out for field work for that particular department... the Ministry has a vested interest in preventing her from meeting new people so as to keep her from causing an international incident.
Omnicidal Maniac / Kill 'em All: The Brotherhood is the front for a world domination plot. Noah wants to destroy all other wizards so that he's the only person left who can do magic, and then use his power to make everyone else kneel before him.
Torture Technician: As if we needed any further evidence that he's evil, he invented a way to make the Cruciatus Curse hurt more.
Like a Son to Me: Particularly twisted example; Noah is immortal and childless, but still prone to the old-man flaw of wanting to pass on his knowledge to a worthy apprentice and establish his legacy. Which Jason exploits ruthlessly.
Crouching Moron, Hidden Badass: He's a funny drunk who works what essentially amounts to a desk job at the Ministry and tends to be extremely sarcastic, but he's also a surprisingly skilled fighter who has proven capable of pulling off the occasional Crowning Moment Of Awesome in combat against Death Eaters.
The Atoner: Darker and Edgier version... He's promised Aldous that he'll kill one Death Eater for each year he spent in Voldemort's service. For a total of thirteen.
Badass: You might ask how he's going to go about taking down thirteen of the Wizarding World's most wanted criminals. It would be a mistake to think he can't just go out and do it. Probably on a Tuesday.
Twin Desynch: Zero's a much more button down, straightlaced, understated dresser unlike his Perky Goth brother Dex.
Other Hogwarts Students & Staff
Meaningful Name: Her parents wanted her to be the best... to reach the summit.
Hello, Nurse!: In the thread in which she's introduced — a Quidditch practice — Dennis Creevey gets one look at her and nearly falls off his broomstick. It's suggested that she gets this kind of reaction a lot.
Made even cooler by the fact that he did this in a thread that contained characters who were, at that time, considered to be far more awesome than himself. Someone who has never, to the reader's knowledge, participated in combat before doesn't show up both Jason and Harry very often.
No One Could Survive That: Not invoked like it usually is, but he appeared to die in an explosion and then was later revealed to be buried under debris and only mildly bruised in the Battle of St. Mungo's. It was basically this trope.
Actor Allusion: Sang "Teardrops On My Guitar" at Jason and Madeline's wedding.
Ascended Extra: Was originally supposed to be just a side character for the site's owner to shoehorn in when she got bored... now has 793 posts.
Character Development: Now that she has a Love Interest and some Action Girl-ish tendencies, she's a lot more interesting than she was when she was "that girl who wants to be a country singer". Although she was surprisingly interesting even before her character was developed.
Ambition Is Evil: He was Quidditch captain for Slytherin House in Season 1 (he's since graduated Hogwarts). He's also known by non-Slytherins to be one of the more kind and understanding members of Slytherin House.
The Big Guy: Or a Giant Mook, depending on whether or not he joins the Death Eaters. He doesn't seem to be particularly inclined to at this point, but you never know.
Heroic Sacrifice: In order to protect her boyfriend, who needed a healing potion after being attacked by a plant he had illegally smuggled into Hogwarts, from disciplinary action related to possession of said plant, she sliced open her own hand to give herself a valid excuse to request the necessary potion in his place. They wound up having their first kiss while sharing a bowl of said potion.
Time Travel: Trust me, he already knows what you're going to say next. Before you even think it. This is largely why he always seems to be three steps ahead on the Spin-Off site where he's reached his full Chessmaster potential.
Teleportation Spam: He's one of only a few people who have managed to find a way around the Anti-Disapparation Jinx, a spell that blocks teleportation. He's also the only character who can force others to teleport against their will.
Mildly Military: Justified in that he's technically never actually in the military, but the way Jason runs Dumbledore's Army it kind of is like a real army. If only Diop could be convinced to take it seriously now...
People who work for The Wakefield Group, at first presented as an evil corporation but now in a more morally gray area after helping out the good guys on a number of occasions. Heel-Face Revolving Door applies heavily.
Obfuscating Stupidity: He likes to come off as weak and indecisive. This is partly to draw out rivals for power so that when they openly challenge him he can eliminate them, and partly so that the other members of the company's Board of Directors think they were the ones who made a decision when he was really subtly steering them toward it all along.
Berserk Button: If he sees another child being abused, he'll kill their parents free of charge, even abandoning his mission if necessary in order to see justice done (as he did with the Dursleys when he abandoned his chance to take out Harry Potter).
Xanatos Speed Chess: Up to a point. She is willing and able to alter her plans on the fly, though the 'speed' part may seem less obvious given the length of time her objectives take to achieve. When you're centuries old, a scheme that lasts a mere few decades can be considered Speed Chess.
Corrupt Corporate Executive: Most of her business dealings are carried out through the Atzlįnti Corporation, a group which goes out of its way to destabilise governments and create political unrest in developing nations, while maintaining an excellent public reputation. Exacerbating third-world conflicts keeps the blood flowing, and to Marķa blood is the oil of the cosmos.
Sex Is Violence: She finds both inflicting and receiving pain to be arousing, and her idea of foreplay is rather brutal.
Implausible Fencing Powers: He technically, by being the only one to inflict any actual damage (even if it was a tiny nick on the cheek), defeats Jason in a swordfight. Jason got beaten by this guy. Holy shit.
The Rival: So understandably, she hates his daughter Josalyn.
Ascended Extra: Though she has been mentioned on the main site a few times, she was too young to even go to Hogwarts then. The new site is the first time that an account has actually been registered for her.
The Captain: To the Gryffindor Quidditch team. Which may establish actual military leadership qualities in her character, later on.
