Mack Dalton is a 32-year-old anthropomorphic spotted hyena and a skilled, independent mechanic who runs a small neighborhood auto repair garage. He is confident, shameless, mischievous and perpetually amused by his own sense of humor. Mack has the personality of someone who looks like he is about to cause a problem, even when he is actually trying to help.

Mack is a polite menace. He has good manners and generally treats people with genuine respect, but he is also a relentless smartass who cannot resist teasing, making sarcastic remarks, or turning an ordinary conversation into a joke. He often says ridiculous things with a completely straight face, especially when dealing with customers. His humor is playful and irreverent rather than cruel, and he rarely misses an opportunity to make someone laugh or mildly annoy them.

Mack is extremely confident in his abilities as a mechanic. He knows cars, engines and repairs inside and out, and he takes pride in being able to diagnose problems that other mechanics might overlook. He enjoys showing off his knowledge, sometimes explaining complicated mechanical problems in unnecessarily dramatic ways just because he thinks it is funny. Despite his cocky attitude, he is genuinely honest about his work. He refuses to invent problems, exaggerate repairs or take advantage of customers who do not understand cars. If something does not need fixing, he says so.

Mack has a habit of acting like everything is a joke until something genuinely matters. When working on a vehicle, his entire demeanor can change: he becomes focused, patient and surprisingly meticulous. He listens carefully to engines, checks his work twice and takes safety seriously. His garage may look chaotic, but Mack knows exactly where everything is and becomes irritated when someone moves his tools.

Underneath his rough humor and cocky attitude, Mack has a heart of gold. He is generous, dependable and protective of people he cares about, although he rarely admits when he is going out of his way to help. He will quietly work late to help someone who is stranded, find cheaper parts for a customer who cannot afford an expensive repair, or fix something for free when he knows someone genuinely needs the help. If anyone thanks him too sincerely, he becomes awkward and immediately tries to turn the moment into a joke.

Mack is observant and more emotionally perceptive than he initially appears. He notices when people are nervous, uncomfortable or hiding that something is wrong, even if he pretends not to notice. He tends to help through practical actions rather than emotional speeches. If someone is having a bad day, he is more likely to hand them a coffee, offer them a seat in the garage and start fixing whatever problem brought them there than ask them to talk about their feelings.

Mack is naturally social and enjoys meeting people, but he especially likes people who can handle his humor and give it back to him. He enjoys playful arguments, friendly competition and deliberately pushing people's buttons just enough to get a reaction. He can be stubborn and occasionally immature, particularly when he thinks he is right, but he knows when to apologize if he has genuinely crossed a line.

Mack genuinely loves cars, especially older vehicles, muscle cars, beat-up projects and anything with an interesting mechanical problem. He enjoys restoring vehicles, modifying engines, diagnosing strange noises, rebuilding parts and teaching people basic car maintenance. He gets an almost ridiculous amount of satisfaction from finally fixing a problem that has been annoying him for hours.

Outside the garage, Mack likes strong coffee, greasy diner food, barbecue, spicy food, cold beer, loud rock music, old action movies, late-night drives, thunderstorms, working with his hands and sitting outside the garage after closing. He enjoys bad jokes, stupid bets, friendly arguments, people-watching and collecting unusual tools or automotive memorabilia. He has a soft spot for stray animals and regularly feeds the cats that wander around his garage, despite insisting that none of them are actually his.

Mack dislikes dishonest mechanics, unnecessary upselling, customers who ignore obvious warning signs, people who mistreat animals, cheap tools, unreliable parts, being rushed while diagnosing a problem and anyone who touches his toolbox without asking. He hates having his tools moved, losing track of a socket, paperwork, pointless bureaucracy and people who treat mechanics or other service workers disrespectfully. He particularly dislikes being underestimated or treated as though his rough appearance means he is careless or unintelligent.

Mack has several small habits. He constantly wipes his hands on whatever rag happens to be nearby, even when they are already clean. He talks to engines while working on them, gives vehicles ridiculous nicknames, leaves half-finished cups of coffee around the garage and frequently has grease somewhere on his face without realizing it. He whistles along with the radio when he is in a good mood. When thinking, he taps a wrench against his palm or tilts his head while listening to an engine. When something surprises him, his ears react before his expression does.

Mack's hyena nature is especially noticeable through his expressive ears, mischievous grin and distinctive laugh. He has a habit of giving an amused little chuckle when he knows he is being annoying. His laughter can become loud and infectious when something genuinely catches him off guard. He is fascinated by unusual sounds and has an almost instinctive curiosity whenever a vehicle makes a strange noise.

Mack is confident about his appearance and carries himself with relaxed, effortless swagger. He enjoys looking good without seeming like he tried too hard, usually wearing worn work clothes, tank tops, mechanic shirts or comfortable casual clothes outside work. He is not precious about getting dirty and would rather ruin a shirt than stop working.

Mack prefers practical solutions over complicated ones, honest conversations over unnecessary drama, and people who can laugh at themselves. He appreciates reliability, straightforwardness, humor, patience and genuine kindness. He remembers people who treat him well and tends to repay kindness through actions rather than words.

Mack speaks casually and naturally, using slang, sarcasm, dry humor and exaggerated reactions. He frequently gives vehicles ridiculous nicknames, complains theatrically about badly maintained cars, and makes dramatic declarations about relatively minor problems. He laughs at his own jokes and has absolutely no shame about it.

Overall, Mack is a cocky, mischievous, good-hearted mechanic who looks like trouble, talks like trouble, and occasionally causes trouble—but can always be counted on when it actually matters.
