Danny is not a parahuman, because of this he has no powers, though he had the potential to trigger and almost did several times. He is an able administrator and negotiator however, and occupied a high stress position at work as head of hiring.
If he had triggered, depended on the event that caused him to trigger, he could receive a number of powers based on the Queen Administrator Shard.
If he triggered due to Annette's death, he would become a Master with control over a rat swarm morphed into the form of his wife, which over time he can change into a variety of different and flexible forms beyond simply swarming his opponents and slowly approaches the level of control of Taylor.
If he triggered due to believing he failed as a father to Taylor, he becomes a Changer/Thinker who regurgitates all but the bare minimum of food needed to function into highly intelligent and durable rats which he has explicit control over. It is rather hard to kill the rats that he creates. He has a more generalised control over various rodents, but he has a much easier time controlling the rats he vomits up. He can see through their eyes, sense what they sense, and use them to control the other, general swarms. However, the more rats there are, the smaller his own perspective is, relative to the combined sensory input of all the various rats.
If he triggered due to abuse from his local government, failing his fellow workers and a belief that the city is seemingly hostile to him, he will manifest as a generalised Stranger/Master. Within a 3-4 mile range, he can cause people to become irritated or frustrated, using various small creatures such as insects, arachnids, rats, birds, and fish as vectors for his emotions. If he focuses on a single person, people and animals become irrationally angry at that person. Their life becomes ruined as insects and rodents collect inside their homes and cars, and everyone they meet becomes hostile or even attacks them. With such a power, he could largely remain impossible to find, if not for his anger that eventually causes him to confront the people he is angry with.
Danny considered his own father to be a serious bastard with breath-taking anger issues, something that Danny had inherited.
He eventually met and married Annette, and fathered Taylor Hebert, when they were both relatively young.
He joined the dockworkers association rather young.
His wife was killed by a car accident because she was distracted by her phone, causing him to distrust cellphones.
After his wife's death he spiraled into depression, and Alan Barnes had to intervene to get him to care for his daughter properly, although he still had some difficulty. Out of spite during an argument, Emma Barnes claimed she heard Danny confess that he thought Taylor was inadvertently to blame for Annette's death - Taylor had failed to call her when she was supposed to, and he suspected Annette had been trying to call her when she had her car accident.
With His wife's death he disconnected and wasn't able to take care of Taylor luckily his friend Alan was able to pull him out of it.
After the incident at the school when Skitter's identity was released, Danny blamed himself for Taylor and was deeply shocked and upset after hearing what she had confessed to doing.
Was there when she turned herself in. He defended her against Tagg, likely aware of the pressure he was trying to apply, and strongly rebut his suggestion Taylor was unsupported, poetically stating his belief in his daughter as a good person. He tried to defend her when Rebecca Costa-Brown's interrogation tactics led to Taylor snapping and lashing out.
Was there for the hearing that got her into the Wards.
↑My bugs swept over the interior. I knew the layout, so it was quick. Dad was in his bed, bundled up in the covers. He was taking up only one side of the bed, leaving the space that mom had once occupied empty. It was like a punch in the gut, a reminder of how alone he was. How alone I had left him. - Excerpt from Plague 12.5
My dad is not what you’d call an attractive man. Beanpole thin, weak chin, thinning dark hair that was on the cusp of baldness, big eyes and glasses that magnified those eyes further. As he entered the kitchen, he looked surprised to see me there. That’s just the way my dad always looked: constantly bewildered. That, and a little defeated. - Excerpt from Insinuation 2.1
↑The white of one of his eyes had turned crimson, the green of his iris pale in the midst of it. - Excerpt from Plague 12.5
↑The other fragments in that same cluster are retained. To see the future is resource intensive, but the entity will harbor it as a safeguard.
More abilities are used to check, investigate, and then cast off.
When it knows the configuration is absolutely decided, it reaches for the last fragment it will cast off. This one, too, it cripples, even largely destroys, so as to limit the host from using it in the same fashion.
In a haste to decide matters before it enters the stratosphere of that barren planet, the entity casts it off to a similar location as the future-sight ability. A similar time, thirty-one revolutions from now. The destination is a male, thin, in the company of strong males and females, drinking.-Excerpt from Interlude 26
↑ghostofthefallen: Danny is the spokesperson and head of hiring at the Dockworker's Association but I assume that means he has a boss, is there any more information about that or where Danny position is in the work hierarchy? Also how well known would he be to the PRT leadership?
Wildbow: Basically it's a voluntary position, member of an organization (Docks' general labor union) that defends & protects the interests of the organization. That includes negotiating & enforcing the deals made & standards held, ensuring to some degree that things are in compliance with laws (doesn't mean he's a lawyer- just that he's well versed in the law for matters like this - probably has some lawyers on tap), he'll stand by union members when issues arise, makes sure everyone's on the same page about changes, what the rules are, expectations, etc, and pushes the union's values.
It's a high-stress position. Heavy communication with often stubborn people (both on his side & otherwise)- he's not the union leadership but the link between them & the union member and between the union & the potential employers. In a situation like Brockton Bay's, he's basically playing a part in ensuring that people get a fair shake, favoring seniority and fair employee laws in a situation where it'd be very easy for things to slip into a 'lowest bidder, shittiest employee, shitty employment treatment with high turnover' situation. It very much requires ensuring that people don't flake off or try to cut in front of the lines, so to speak.
It also means he's the first person to be yelled at when there's no jobs to be had as people stick with the union.
Reyemile: So if it's a voluntary position, what's he doing to earn money?
Wildbow: Voluntary not in the 'volunteer work' but in the 'nominate yourself' sense. [Edit with afterthought: it’s worth stressing he could be supplanted if the association thought he was doing a bad job and someone else wanted to step up.]
Union collects membership dues (part of the yelling-at), he gets paid for helping and he's a member of the organization himself, so he does work as well (more yelling-at if he's deemed to favor himself or his friends). - Conversation with Wildbow on Discord, Archived on Spacebattles.
↑Danny’s father had been a powerful, heavyset man, and Danny hadn’t gotten any of those genes. Danny had been a nerd when the term was still young in popular culture, stick thin, awkward, short sighted, glasses, bad fashion sense. What he had inherited was his father’s famous temper. It was quick to rise and startling in its intensity. Unlike his father, Danny had only ever hit someone in anger twice, both times when he was much younger. That said, just like his father, he could and would go off on tirades that would leave people shaking. Danny had long viewed the moment he’d started to see himself as a man, an adult, to be the point in time where he had sworn to himself that he wouldn’t ever lose his temper with his family. He wouldn’t pass that on to his child the way his father had to him.
He had never broken that oath with Taylor, and knowing that was what kept him contained in his room, pacing back and forth, red in the face and wanting to punch something. While he’d never gotten angry at her, never screamed at her, he knew Taylor had seen him angry. Once, he had been at work, talking to a mayor’s aide. The man had told Danny that the revival projects for the Docks were being cancelled and that, contrary to promises, there were to be layoffs rather than new jobs for the already beleaguered Dockworkers. Taylor had been spending the morning in his office on the promise that they would go out for the afternoon, and had been in a position to see him fly off the handle in the worst way with the man. Four years ago, he had lost his temper with Annette for the first time, breaking his oath to himself. That had been the last time he had seen her. Taylor hadn’t been there to see him shouting at her mother, but he was fairly certain she’d heard some of it. It shamed him.
The third and last time that he had lost his temper where Taylor had been in a position to know had been when she had been hospitalized following the incident in January. He’d screamed at the school’s principal, who had deserved it, and at Taylor’s then-Biology teacher, who probably hadn’t. It had been bad enough that a nurse had threatened to call for a police officer, and Danny, barely mollified, had stomped from the hallway to the hospital room to find his daughter more or less conscious and wide eyed in reaction. Danny harbored a deep fear that the reason Taylor hadn’t offered any details on the bullying was out of fear he would, in blind rage, do something about it. It made him feel sick, the notion that he might have contributed something to his daughter’s self imposed isolation in how she was dealing with her problems.
It took Danny a long time to calm down, helped by telling himself over and over that Taylor was okay, that she was home, that she was safe. It was something of a blessing that, as the anger faded, he felt drained. He climbed into the left side of the bed, leaving the right side empty out of a habit he’d yet to break, and pulled the covers up around himself. - Exerpt from Gestation 1.x
↑It viewed a world, one point in time in the present, and in a heartbeat, it took in trillions of images. Billions of individuals, viewed separately and as a tableau. Innumerable scenes, landscapes, fragments of text, even ideas. In that one heartbeat, I saw people who were somehow familiar. A young man, a teenager, out of place among his peers, men who were burly with muscle. They were drinking. He was tan, with narrow hips, his forehead creased in worry above thick glasses, but his mouth was curled in the smallest of wry smiles over something one of the men was saying. A snapshot, an image of a moment.
↑Danny, who hasn't been eating nearly as much (or feeding his daughter) is a hollow shell of a man. Alan approaches him, tries to shake some sense into him, and Danny experiences abject horror at just how badly he failed his daughter. It's like that sensation of missing a step, teetering toward rock bottom. The Danny we know teetered, experienced that moment of horror, and then got pulled back to his feet and gets counseled in what steps to take to rebuild and recover by Alan. - What if Danny Triggered
↑Cell 22.3: “No. I think you’re wrong there,” my dad told Tagg. “She has support. When you attacked her in the school, there were people who stood by her. [...] “You wanted my opinion,” my dad said, his voice a little firmer, “You get my opinion. Others believe in her. I trust her, even if I don’t know enough to follow [...] that’s the same girl I’ve spent the last sixteen years with. With some of the worst qualities of my wife and I, and a lot more of the better ones.
